  • Fourth of July Outlook: What Maryland Can Expect on Independence Day 🇺🇸

    Fourth of July Outlook: What Maryland Can Expect on Independence Day 🇺🇸

    As Maryland prepares to celebrate Independence Day, all eyes are on the weather. The good news is that Saturday is not expected to be a washout, but it will come with two weather concerns everyone should plan around: dangerous heat and the potential for scattered afternoon and evening thunderstorms.

    Quick Outlook

    • 🌞 Hot and humid from start to finish
    • 🌡️ Afternoon temperatures in the upper 90s to near 100°
    • 🥵 Heat index values between 105° and 110° in many areas
    • ⛈️ Scattered thunderstorms developing during the afternoon and evening
    • 🎆 Many fireworks displays should be able to happen, but some locations may need to monitor storms closely

    What We’re Watching

    Saturday begins quietly with sunshine and rapidly warming temperatures. By afternoon, Maryland will once again experience dangerous heat, making it important to stay hydrated, take frequent breaks, and avoid prolonged time outdoors during the hottest part of the day.

    The biggest forecast question is where thunderstorms develop during the late afternoon and evening. Current guidance suggests that storms will remain scattered, meaning many communities could stay dry while others experience heavy rain, gusty winds, and frequent lightning.

    Because these storms will be scattered, it’s too early to determine exactly which fireworks displays could be affected. We’ll continue monitoring updated forecast guidance throughout the evening and overnight and provide the latest information Saturday.

    Planning Ahead

    If you’re attending a parade, cookout, festival, or fireworks display:

    • Plan for dangerous heat throughout the day.
    • Drink plenty of water and seek shade often.
    • Keep a close eye on the forecast if you’ll be outside during the evening.
    • Have a backup plan in case thunderstorms develop nearby.

    Stay With MD Weather Alerts

    We’ll be tracking the forecast through the night and throughout Independence Day, including any updates to storm timing, heat alerts, or impacts to fireworks displays across Maryland.

    Check back Saturday morning for the latest statewide forecast before heading out to celebrate.

    Have a safe, fun, and weather-aware Fourth of July! 🇺🇸🎆

  • Maryland Weather Forecast for Friday, July 3, 2026: Dangerous Heat Continues Before Holiday Weekend

    Maryland Weather Forecast for Friday, July 3, 2026: Dangerous Heat Continues Before Holiday Weekend

    Another dangerously hot day is ahead across Maryland as the prolonged heat wave continues. Heat Advisories and Extreme Heat Warnings remain in effect for much of the state, with afternoon heat index values reaching between 100° and 110° or higher in many communities. While the majority of Friday will stay dry, isolated to scattered thunderstorms may develop late in the afternoon and evening, especially across western and northern Maryland, with a few storms capable of producing gusty winds, lightning, and heavy downpours. (National Weather Service⁠)

    Morning Commute (6:00 AM – 9:00 AM)

    The morning commute will be quiet statewide with mostly sunny skies and warm, humid conditions already in place.

    Temperatures will begin the day in the low to mid-70s across most of Maryland, with upper 60s in the higher elevations of Garrett County. Humidity will make it feel warmer than the thermometer indicates, and temperatures will rise quickly after sunrise.

    Travel conditions will be excellent with dry roads, light southwest winds, and good visibility.

    Daytime Forecast

    Friday afternoon will once again bring dangerous heat to nearly every corner of Maryland.

    Western Maryland (Garrett, Allegany, Washington):
    Highs will range from the upper 80s in Garrett County to the middle and upper 90s in Allegany and Washington counties. While slightly cooler than central Maryland, the humidity will still make conditions uncomfortable. Thunderstorm chances increase late in the afternoon, especially over the mountains.

    North-Central Maryland (Frederick, Carroll):
    Expect highs in the upper 90s with heat index values between 102° and 107°. Most areas stay dry through the afternoon before isolated storms become possible late in the day.

    Baltimore Metro (Baltimore City, Baltimore, Harford, Howard, Anne Arundel):
    One of the hottest regions of the state. Afternoon temperatures will reach the upper 90s to near 100°, with heat index values commonly between 105° and 110°. Heat-related illnesses can develop quickly for anyone spending extended time outdoors.

    Washington Metro & DC Suburbs (Montgomery, Prince George’s):
    Highs near or just above 100° with oppressive humidity. Heat index values may approach or exceed 110° during the afternoon. Limit strenuous outdoor activity during peak heating.

    Southern Maryland (Charles, Calvert, St. Mary’s):
    Temperatures climb into the upper 90s with heat indices near 105° to 110°. Areas along the Chesapeake Bay and Potomac River may be a few degrees cooler but will remain extremely humid.

    Upper Eastern Shore (Cecil, Kent, Queen Anne’s, Caroline, Talbot):
    Highs in the middle to upper 90s inland with dangerous heat index values over 100°. Bay communities will see only modest relief.

    Lower Eastern Shore (Dorchester, Wicomico, Somerset, Worcester):
    Temperatures in the middle and upper 90s away from the water. Ocean City and Assateague will remain considerably cooler, generally in the lower to middle 80s, thanks to an afternoon sea breeze.

    Evening Forecast

    The evening remains very warm and humid with temperatures holding in the 80s well after sunset.

    Isolated to scattered thunderstorms may develop from western Maryland into portions of central and northern Maryland during the late afternoon and evening. While not everyone will see rain, any storm that develops could produce:

    • Gusty winds
    • Frequent cloud-to-ground lightning
    • Brief torrential rainfall
    • Localized ponding on roads

    Storm coverage becomes much more isolated farther south and across much of the Eastern Shore, where many communities will remain dry through the evening. (National Weather Service⁠)

    Chesapeake Bay & Marine Forecast

    Southwest winds generally 10 to 15 knots will continue across the Chesapeake Bay. Boaters should remain alert for any thunderstorms developing late in the day, as locally stronger winds and dangerous lightning can develop quickly.

    Heat Safety

    Friday remains another high-impact heat day across Maryland.

    • Stay hydrated throughout the day.
    • Take frequent breaks if working outdoors.
    • Wear lightweight, light-colored clothing.
    • Never leave children or pets in parked vehicles.
    • Check on elderly neighbors, family, and friends.
    • Walk pets during the early morning or later in the evening when pavement temperatures are lower.
    • If possible, place fresh water outside for birds and local wildlife during the prolonged heat.

    Forecast Highlights

    • 🌞 Mostly sunny and dangerously hot statewide.
    • 🌡️ High temperatures from the upper 80s in Garrett County to near 100° across central Maryland.
    • 🥵 Heat index values of 100° to 110° common across much of the state.
    • ⛈️ Isolated late afternoon and evening thunderstorms, mainly west and north.
    • 🌙 Warm, humid evening with temperatures remaining in the 80s after sunset.

    Maryland remains under the influence of an intense summer heat dome through Friday. If you have outdoor plans before the holiday weekend, complete them early in the day if possible, stay hydrated, and continue monitoring for any updated heat alerts or late-day thunderstorm development.

  • Maryland Heat Wave Outlook: July 1–4, 2026

    Maryland Heat Wave Outlook: July 1–4, 2026

    Maryland is heading into a significant heat wave beginning Wednesday, July 1 and continuing through at least Saturday, July 4.

    This will be more than a typical hot summer stretch. Multiple days of heat and humidity will create dangerous conditions across much of the state, especially away from the mountains and immediate Atlantic beaches. Heat index values may reach the 100s for many communities, with some areas possibly feeling close to 105 to 110 degrees during the hottest periods.

    The heat will build in stages. Wednesday is the first major day. Thursday and Friday look like the peak of the heat for many areas. Saturday, Independence Day, may still be very hot, but storm chances may begin increasing as the heat dome starts to weaken.

    The main message for Maryland: take this heat seriously, prepare early, and limit outdoor activity during the hottest part of each day.

    Heat Wave Overview

    A strong ridge of high pressure will build over the region, allowing hot air to settle over Maryland. At the same time, humidity will increase, making temperatures feel even hotter than what the thermometer shows.

    This pattern will likely bring:

    • Multiple days in the 90s
    • Some lower-elevation areas near or above 100 degrees
    • Heat index values over 100 for many counties
    • Limited cooling at night in urban and low-elevation areas
    • Increasing heat stress for outdoor workers, pets, kids, older adults, and anyone without reliable cooling
    • Low rain chances early in the heat wave
    • Increasing thunderstorm chances by Friday and Saturday

    Western Maryland and the beaches will be somewhat cooler than inland central Maryland, Southern Maryland, and the Eastern Shore, but every part of Maryland will feel the heat in some way.

    Wednesday, July 1: Heat Wave Begins

    Wednesday is the first major day of dangerous heat across Maryland.

    Morning conditions will be mostly quiet and dry, but temperatures will rise quickly after sunrise. By afternoon, much of the state will be in the 90s. Heat index values may reach 100 to 105 degrees in many lower-elevation and urban areas.

    A few isolated storms may try to develop during the afternoon or evening, especially near the mountains, Blue Ridge, or local boundaries such as the Chesapeake Bay breeze. Most areas will stay dry, but any storm that forms could bring gusty winds, heavy rain, and lightning.

    Wednesday Heat Focus

    The hottest areas Wednesday will likely include the I-95 corridor, Baltimore metro, D.C. suburbs, north-central Maryland, inland Southern Maryland, and inland Eastern Shore communities.

    Garrett County and the immediate Atlantic beaches will be cooler, but still warm and humid.

    Thursday, July 2: Extreme Heat Expands

    Thursday looks like one of the most dangerous days of the heat wave.

    Many inland areas may reach the upper 90s to near or above 100 degrees. Heat index values could reach 105 to 110 degrees in parts of central Maryland, northern Maryland, Southern Maryland, and the Eastern Shore.

    The risk becomes higher because this is not just one hot afternoon. By Thursday, the body is already dealing with the heat from Wednesday, and overnight temperatures may not cool enough for full relief in some areas.

    Rain chances remain low for most of Maryland, meaning there may not be much cloud cover or rain-cooled air to help.

    Thursday Heat Focus

    Thursday may bring dangerous to extreme heat across much of Maryland, especially from Frederick, Carroll, Montgomery, Howard, Baltimore, Harford, Cecil, Anne Arundel, Prince George’s, Charles, Calvert, and St. Mary’s counties eastward into the Eastern Shore.

    Western Maryland will still be hot, especially Allegany and Washington counties, but Garrett County remains somewhat cooler due to elevation.

    Friday, July 3: Peak Heat Continues, Storm Risk Begins Increasing

    Friday may be another extremely hot day across Maryland.

    Temperatures may again reach the upper 90s to near or above 100 degrees in many inland areas. Heat index values could again reach the 105 to 110 degree range in the hottest spots.

    By Friday afternoon and evening, storm chances may begin increasing as the heat dome starts to weaken slightly and disturbances move closer to the region. This does not guarantee storms everywhere, but any storms that form could become strong because of the extreme heat and humidity already in place.

    Possible storm hazards Friday include:

    • Damaging wind gusts
    • Frequent lightning
    • Heavy downpours
    • Large hail in stronger storms
    • Rapidly changing outdoor conditions

    Friday is a day to watch closely if you have travel, outdoor work, beach plans, evening events, or early holiday weekend activities.

    Saturday, July 4: Still Hot for Independence Day, Storms Possible

    Saturday, July 4, may still be hot and humid across Maryland, even if temperatures begin to ease slightly in some areas.

    Many communities may still reach the 90s, with heat index values over 100 possible. The Eastern Shore, Southern Maryland, central Maryland, and the I-95 corridor may still feel very uncomfortable.

    Thunderstorm chances may be higher Saturday compared to Wednesday and Thursday. This is important for Independence Day plans, fireworks, cookouts, parades, beach trips, and outdoor events.

    Saturday does not look like an all-day washout at this point, but storms could interrupt plans, especially during the afternoon and evening. Any storm that develops in this kind of hot and humid air could be intense.

    The key message for July 4: plan for heat first, but also have a storm backup plan.

    Heat Risk by Maryland Region

    Western Maryland

    Garrett County will be the coolest part of Maryland during this heat wave, but it will still be warmer than normal. Deep Creek Lake, Oakland, Grantsville, and surrounding mountain areas may stay mostly in the 80s, with lower heat index values compared to the rest of the state.

    Allegany and Washington counties will be much hotter, especially in the lower elevations. Cumberland, Frostburg, LaVale, Hagerstown, Williamsport, Boonsboro, and surrounding areas may reach the 90s on multiple days, with heat index values climbing near or above 100.

    Western Maryland may also have some of the earlier isolated storm chances, especially near the mountains.

    North-Central Maryland

    Frederick, Carroll, Montgomery, and Howard counties will see dangerous heat build quickly.

    Frederick, Westminster, Rockville, Germantown, Gaithersburg, Silver Spring, Columbia, Ellicott City, and surrounding communities should prepare for multiple days of highs in the mid to upper 90s, with some locations possibly near 100.

    Heat index values may reach 105 or higher at times, especially Thursday and Friday.

    Baltimore Metro and Northern Maryland

    Baltimore City, Baltimore County, Harford, Cecil, and Anne Arundel counties will be in a high-risk heat zone.

    Baltimore City may feel especially hot because urban areas hold heat longer into the evening. Towson, Catonsville, Owings Mills, Perry Hall, Bel Air, Aberdeen, Havre de Grace, Elkton, Glen Burnie, Annapolis, and surrounding areas should expect dangerous heat, especially Thursday and Friday.

    Areas near the Chesapeake Bay may be slightly cooler at times, but humidity will still make it feel very uncomfortable.

    Southern Maryland

    Prince George’s, Charles, Calvert, and St. Mary’s counties will also see dangerous heat.

    Bowie, College Park, Upper Marlboro, Waldorf, La Plata, Prince Frederick, Chesapeake Beach, North Beach, Solomons, Leonardtown, Lexington Park, and surrounding communities should expect multiple days in the 90s, with heat index values possibly reaching 105 or higher.

    Bay and river communities may be slightly cooler, but not cool enough to remove the heat risk.

    Eastern Shore

    The Eastern Shore will deal with significant heat, especially inland.

    Kent, Queen Anne’s, Talbot, Caroline, Dorchester, Wicomico, Somerset, and Worcester counties should prepare for a major heat risk from Wednesday through Saturday, with the most dangerous heat likely Thursday and Friday.

    Chestertown, Centreville, Easton, Denton, Cambridge, Salisbury, Princess Anne, Snow Hill, Pocomoke City, and other inland Shore communities may reach the mid to upper 90s or higher. Heat index values could climb into the 100s, with some areas possibly near 110 during the peak.

    Ocean City, Assateague, and the immediate coast will be cooler thanks to the Atlantic influence, but beachgoers still need to take the heat seriously because sun exposure, humidity, and crowded outdoor conditions can still create heat stress.

    County-by-County Heat Breakdown

    Garrett County

    Garrett County stays cooler than the rest of Maryland because of elevation, but it will still be warm. Highs may mostly stay in the 80s, with the warmest days late week. Deep Creek Lake and Oakland will be more comfortable than most of the state, but outdoor activity should still include water breaks and sun protection.

    Allegany County

    Allegany County will be hot, especially around Cumberland and lower elevations. Heat index values may reach near or above 100 during the hottest afternoons. Higher elevations near Frostburg will be somewhat cooler, but the heat will still be noticeable.

    Washington County

    Washington County will see a major increase in heat, especially Wednesday through Friday. Hagerstown, Williamsport, Boonsboro, and Hancock should prepare for highs in the 90s and heat index values near or over 100. Friday and Saturday may also bring increasing storm chances.

    Frederick County

    Frederick County will be very hot during this heat wave. Frederick, Thurmont, Brunswick, Urbana, and Walkersville may see highs in the upper 90s at times, with heat index values reaching dangerous levels, especially Thursday and Friday.

    Charles County

    Charles County will be very hot and humid. Waldorf, La Plata, Indian Head, Bryans Road, and surrounding areas should plan for highs in the 90s and heat index values in the 100s. Outdoor activity should be limited during the afternoon.

    Calvert County

    Calvert County will be hot, even with some Bay influence. Prince Frederick, Dunkirk, Chesapeake Beach, North Beach, Lusby, and Solomons should expect very warm to hot conditions. Inland areas will feel the worst of the heat, while waterfront areas may be slightly cooler but still humid.

    St. Mary’s County

    St. Mary’s County will be hot and humid through the heat wave. Leonardtown, Lexington Park, California, Charlotte Hall, and surrounding areas should expect highs in the 90s with dangerous heat index values possible. Bay and river areas may be slightly cooler, but humidity remains high.

    Kent County

    Kent County will see significant heat, especially inland. Chestertown, Rock Hall, Galena, and nearby communities should expect highs in the 90s, with heat index values climbing into the 100s during the peak heat. Waterfront areas may be slightly cooler but still uncomfortable.

    Queen Anne’s County

    Queen Anne’s County will be hot and humid, especially away from the Bay. Centreville, Stevensville, Kent Island, Grasonville, and surrounding areas should prepare for dangerous heat index values Thursday through Saturday. Kent Island may be slightly cooler near the water but still humid.

    Talbot County

    Talbot County will be very hot inland. Easton, St. Michaels, Oxford, Trappe, and surrounding communities should expect highs in the 90s, with the hottest stretch Thursday and Friday. Waterfront towns may be a little cooler, but the heat risk remains.

    Caroline County

    Caroline County will likely be one of the hotter inland Eastern Shore areas. Denton, Greensboro, Ridgely, Federalsburg, and surrounding areas should prepare for highs in the upper 90s to near 100, with heat index values possibly around 105 to 110 during the peak.

    Dorchester County

    Dorchester County will be hot and humid. Cambridge, Hurlock, Secretary, and surrounding areas should expect dangerous heat index values during the peak of the heat wave. Areas near the water may be slightly moderated, but inland locations will feel very hot.

    Wicomico County

    Wicomico County will face significant heat, especially around Salisbury, Fruitland, Delmar, and surrounding areas. Highs may reach the mid to upper 90s during the peak, with heat index values possibly near 105 to 110. Storm chances may begin increasing by Saturday.

    Somerset County

    Somerset County will be hot and humid, especially inland around Princess Anne. Crisfield and waterfront communities may be slightly cooler, but humidity and sun exposure will still create heat stress. Heat index values may become dangerous late week.

    Worcester County

    Worcester County will have a split forecast. Inland areas such as Snow Hill, Berlin, and Pocomoke City may become very hot, with highs in the 90s and heat index values in the 100s. Ocean City and Assateague will stay cooler due to the Atlantic breeze, but beachgoers should still take heat and sun exposure seriously.

    Heat Safety: What Marylanders Should Do

    This heat wave will last multiple days, which makes it more dangerous than a single hot afternoon.

    Marylanders should:

    • Drink water before feeling thirsty
    • Avoid strenuous outdoor work during the afternoon
    • Take breaks in air conditioning or shade
    • Check on older adults, neighbors, and anyone without reliable cooling
    • Never leave children or pets in vehicles
    • Walk pets early in the morning or later in the evening
    • Keep pets indoors during peak heat
    • Watch pavement temperatures for dogs
    • Make sure outdoor animals have shade and water
    • Bring large water containers outside for wildlife, birds, and strays where safe and appropriate
    • Charge devices and make sure weather alerts are enabled
    • Have a backup plan for July 4 outdoor events

    Signs of heat exhaustion can include heavy sweating, dizziness, weakness, nausea, headache, or feeling faint. Heat stroke is an emergency and can include confusion, loss of consciousness, hot skin, or very high body temperature.

    Outdoor Events, Fireworks & July 4 Plans

    The Fourth of July period will need extra planning this year.

    For cookouts, parades, fireworks, beach trips, camps, youth sports, and outdoor events, the biggest concern is heat during the day and possible storms later in the holiday period.

    Plan for:

    • Extra water
    • Shade tents or indoor breaks
    • Cooling areas
    • Earlier setup times
    • Shorter outdoor exposure
    • Pet-friendly cooling plans
    • Radar and lightning monitoring
    • A place to go indoors if storms develop

    The heat alone may be enough to make outdoor events difficult. If thunderstorms develop Friday or Saturday, they could create additional safety concerns with lightning and strong winds.

    Bottom Line

    Maryland is heading into a dangerous heat wave from Wednesday, July 1 through Saturday, July 4.

    Wednesday begins the heat. Thursday and Friday look like the peak, with heat index values potentially reaching 105 to 110 in parts of the state. Saturday may still be very hot for Independence Day, with increasing storm chances that could affect outdoor events.

    Every Maryland county will feel this heat in some way. The mountains and beaches will be somewhat cooler, but the heat risk remains statewide.

    Prepare now, take breaks, check on others, protect pets, and stay weather-aware through the holiday weekend.

  • Wednesday, July 1, 2026 Maryland Forecast: Dangerous Heat Arrives Across the State

    Wednesday, July 1, 2026 Maryland Forecast: Dangerous Heat Arrives Across the State

    Maryland is heading into the first major day of this heat wave, and Wednesday is the day the heat becomes a serious weather concern for much of the state.

    The morning starts mostly quiet and manageable, but temperatures rise quickly after sunrise. By late morning and afternoon, many inland areas will be in the 90s, with heat index values climbing over 100 degrees in several counties. For parts of central Maryland, the Baltimore metro, the D.C. suburbs, northern Maryland, and Southern Maryland, it may feel closer to 105 degrees or higher during the hottest part of the day.

    This is not just a typical warm summer day. This is the beginning of a dangerous stretch of heat that continues into Thursday and Friday.

    The main message for Wednesday: the morning is the safest part of the day to be outside. By afternoon, heat becomes the main concern across Maryland.

    Statewide Overview

    Wednesday will be hot, humid, and mostly dry across Maryland.

    Most areas will see plenty of sunshine through the day. Rain chances are low, but not completely zero. A few isolated showers or storms may try to develop during the afternoon or evening, especially near the mountains, along the Blue Ridge, or near local bay/river breeze boundaries. Most Marylanders will not see rain, but any storm that develops could briefly produce gusty winds, heavy rain, and lightning.

    The bigger and more widespread issue is the heat.

    Heat Advisories are in effect for many parts of Maryland from late morning through the evening. The highest heat index values are expected away from the mountains and away from the immediate Atlantic beaches.

    The hottest areas will likely be along and east of the Blue Ridge, the I-95 corridor, the Baltimore metro, the D.C. suburbs, inland Southern Maryland, and inland parts of the Eastern Shore.

    Western Maryland and the beaches will be somewhat cooler, but not everyone in those areas is fully out of the heat risk. Allegany and Washington counties will still be very hot, and beach areas will still feel humid even with the ocean influence.

    Morning Commute Forecast: 6 AM to 9 AM

    The Wednesday morning commute looks dry and quiet across Maryland.

    Roads should be in good shape statewide with no widespread rain, storms, or fog expected during the main commute window. Temperatures will already be warm, especially across the Baltimore metro, central Maryland, Southern Maryland, and the Eastern Shore.

    Morning temperatures will generally start in the upper 60s to mid 70s. Garrett County and the highest elevations will be cooler, while urban and Bay-adjacent areas may start closer to the mid 70s.

    The morning is the best time for outdoor errands, dog walks, yard work, and anything strenuous outside. Conditions become much more uncomfortable by late morning and afternoon.

    Daytime Forecast

    Wednesday afternoon is when the heat becomes dangerous.

    Most inland areas of Maryland will reach the 90s. Some locations may approach the upper 90s to near 100 degrees, especially across central Maryland, the Baltimore/Washington corridor, and inland Southern Maryland.

    Humidity will push heat index values higher than the actual temperature. In many areas, it may feel like 100 to 106 degrees during the afternoon. A few spots may feel even hotter.

    This is the type of heat that can cause heat exhaustion or heat illness if people are outside too long without breaks, shade, water, or air conditioning.

    Outdoor work, sports practices, camps, errands, and events should be adjusted around the heat. The safest windows are early morning and later evening.

    Evening Forecast

    Wednesday evening stays very warm and humid.

    Temperatures will slowly fall through the 90s and 80s after sunset, but many areas will not cool down quickly. Urban areas, especially Baltimore City and the I-95 corridor, may hold onto the heat longer into the evening.

    A stray shower or thunderstorm cannot be ruled out early in the evening, but most of Maryland stays dry. If a storm does develop, it could produce gusty winds and a quick downpour, but storm coverage should remain limited.

    Evening outdoor plans are not automatically canceled, but it will still feel hot. People should continue to drink water, take breaks, and avoid pushing too hard outside.

    Heat Alerts & Concerns

    Heat Advisories are in effect for many Maryland counties during the late morning, afternoon, and early evening.

    The advisory areas include much of north-central Maryland, central Maryland, the Baltimore metro, northeast Maryland, the D.C. suburbs, parts of western Maryland, and Southern Maryland. This includes areas such as Washington, Allegany, Frederick, Carroll, Montgomery, Howard, Baltimore, Harford, Cecil, Anne Arundel, Prince George’s, Charles, Calvert, and St. Mary’s counties.

    The Maryland Eastern Shore also needs to prepare for worsening heat later this week. Parts of the Upper, Mid, and Lower Eastern Shore are under Extreme Heat Watches for Thursday into Friday or Saturday, when the heat may become even more dangerous.

    Heat safety matters today:

    • Drink water before you feel thirsty
    • Take breaks in shade or air conditioning
    • Limit outdoor work during the afternoon
    • Check on older adults and neighbors without reliable cooling
    • Never leave children or pets in a vehicle
    • Walk pets early or late, not during peak heat
    • Watch pavement temperatures for dogs
    • Know the signs of heat exhaustion and heat stroke

    County-by-County Forecast
