Maryland is heading into a weekend with a very summer-like setup: warm, humid, unsettled at times, and not completely dry for everyone.
This weekend does not look like a total washout, but it also does not look like a weekend where you can ignore the radar. A weak front will hang around the region, and that will help trigger periods of showers and thunderstorms, especially on Saturday. Sunday looks a little better for some areas, but scattered showers and storms may still be around, especially across western, central, and southern parts of the state.
The main message: Saturday is the wetter and more unsettled day. Sunday has more dry time, but it is not completely storm-free everywhere.
Weekend Overview
A slow-moving front will be close enough to Maryland to keep shower and thunderstorm chances in the forecast through the weekend. That means the weather may change quickly from one county to another.
Some areas may get several rounds of rain or storms, while others may only see clouds, humidity, and a few passing showers. This is the type of pattern where it may be dry in one town while it is pouring nearby.
The biggest impacts this weekend will be:
- Periods of showers and thunderstorms
- Brief heavy downpours
- Lightning with any storm
- Patchy fog, especially early Saturday and Sunday morning
- Wet roads at times
- A few stronger storms possible, mainly with gusty winds
- Humid conditions, especially Saturday
At this time, the weekend does not look like a widespread severe weather outbreak for Maryland, but a few stronger storms cannot be ruled out.
Saturday Forecast
Saturday is expected to be the more unsettled day across Maryland.
Many areas will start the morning cloudy, damp, foggy in spots, or dealing with showers. Some rain and storms may already be around during the morning, especially across central Maryland, the Baltimore area, Southern Maryland, and the Eastern Shore.
Through the afternoon, more scattered showers and thunderstorms are possible. These storms may not hit everyone at the same time, but any storm that develops could bring heavy rain, lightning, and briefly gusty winds.
Temperatures on Saturday will depend heavily on clouds and rain. Areas that stay cloudy and wet longer will be cooler, while areas that see breaks of sun may warm up more and become more unstable.
Saturday Morning
Saturday morning may start damp in many areas. Patchy fog is possible, especially where rain falls overnight or early in the morning.
Western Maryland, including Garrett, Allegany, and Washington counties, may see clouds and scattered showers, but the rain coverage may vary. Mountain areas such as Oakland, Deep Creek Lake, Cumberland, Frostburg, and Hagerstown should plan for a cloudy, muggy start with some wet spots possible.
Across Frederick, Carroll, Montgomery, and Howard counties, Saturday morning may bring showers, damp roads, and patchy fog. Frederick, Westminster, Rockville, Germantown, Silver Spring, Columbia, and Ellicott City should expect a humid start with at least some rain chances around.
The Baltimore metro, including Baltimore City, Baltimore County, Anne Arundel, Harford, and Cecil counties, may see showers around during the morning. Baltimore, Towson, Catonsville, Annapolis, Glen Burnie, Bel Air, Aberdeen, Havre de Grace, and Elkton should plan for damp conditions at times.
Southern Maryland, including Prince George’s, Charles, Calvert, and St. Mary’s counties, may also start unsettled. Bowie, Upper Marlboro, College Park, Waldorf, La Plata, Prince Frederick, Chesapeake Beach, Leonardtown, and Lexington Park should be ready for showers or a passing storm.
The Eastern Shore, including Kent, Queen Anne’s, Talbot, Caroline, Dorchester, Wicomico, Somerset, and Worcester counties, has a good chance of seeing showers and storms at times Saturday. Chestertown, Rock Hall, Centreville, Stevensville, Easton, St. Michaels, Denton, Cambridge, Salisbury, Princess Anne, Crisfield, Snow Hill, Pocomoke City, Ocean City, and Assateague should all keep rain gear nearby.
Saturday Afternoon
Saturday afternoon remains unsettled.
Showers and storms may redevelop or continue in waves. This does not mean it rains every minute of the day, but it does mean outdoor plans should have a backup.
For Western Maryland, storms may be more scattered, but any storm that forms over Garrett, Allegany, or Washington counties could bring downpours and lightning.
For central and north-central Maryland, including Frederick, Carroll, Montgomery, Howard, Baltimore County, Baltimore City, Harford, Cecil, and Anne Arundel counties, scattered showers and thunderstorms remain possible through the afternoon. Some stronger cells could produce gusty winds and heavy rain.
For Southern Maryland, including Prince George’s, Charles, Calvert, and St. Mary’s counties, the afternoon could turn more active if storms develop along the nearby boundary. Lightning and brief downpours would be the main concerns.
For the Eastern Shore and beaches, including Kent, Queen Anne’s, Talbot, Caroline, Dorchester, Wicomico, Somerset, and Worcester counties, Saturday may be cloudy and unsettled with showers and storms at times. Ocean City, Assateague, and the coastal areas may stay cooler, but rain and storms remain possible.
Saturday Evening
Saturday evening may still have showers and thunderstorms around, especially across central Maryland, Southern Maryland, and the Eastern Shore.
If you have outdoor plans Saturday evening, keep them flexible. It may not rain the whole evening, but passing showers and storms could cause delays or force people indoors for a while.
Lightning is the biggest safety concern with any storm. If you hear thunder, head inside.
Sunday Forecast
Sunday looks somewhat better than Saturday, but it is not a completely dry forecast statewide.
The day may start with clouds, areas of fog, and leftover showers in a few spots. As the day goes on, some areas may see more dry time and a few breaks of sun. The best improvement may be along parts of the Eastern Shore and beaches, especially later in the day.
However, scattered showers and storms are still possible, especially across western and central Maryland. Some guidance keeps enough moisture around for slow-moving downpours, especially west of I-95.
Sunday Morning
Sunday morning may start cloudy and muggy in many areas, with patchy fog possible where rain fell Saturday night.
Western Maryland, including Garrett, Allegany, and Washington counties, may start mostly cloudy with a lingering shower possible. The mountains and valleys may have some fog early.
Frederick, Carroll, Montgomery, and Howard counties may also begin with clouds, humidity, and patchy fog. A passing shower cannot be ruled out.
Baltimore City, Baltimore County, Anne Arundel, Harford, and Cecil counties may start cloudy or partly cloudy with some damp spots possible. Fog may be around early, especially in areas that picked up rain Saturday night.
Southern Maryland may have a humid start with clouds and a lingering shower possible across Prince George’s, Charles, Calvert, and St. Mary’s counties.
The Eastern Shore may see leftover clouds and showers early, especially across the lower Eastern Shore. Kent, Queen Anne’s, Talbot, Caroline, Dorchester, Wicomico, Somerset, and Worcester counties should improve with time, but a shower cannot be ruled out, especially earlier in the day.
Sunday Afternoon
Sunday afternoon should bring more dry time than Saturday for many areas, but scattered showers and storms are still possible.
Western Maryland could see a few showers or thunderstorms, especially in the mountains and areas west of I-81.
North-central and central Maryland, including Frederick, Carroll, Montgomery, Howard, Baltimore County, Baltimore City, Harford, Cecil, and Anne Arundel counties, may see a mix of clouds, some breaks of sun, and a few scattered showers or storms. The better chance may be west of I-95, but the forecast is not dry enough to fully clear outdoor plans.
Southern Maryland may also see a few showers or storms during the afternoon, especially if the boundary remains close enough. Prince George’s, Charles, Calvert, and St. Mary’s counties should stay weather-aware, but Sunday should still offer more usable dry time than Saturday.
The Eastern Shore and beaches may gradually improve Sunday. Kent, Queen Anne’s, Talbot, Caroline, Dorchester, Wicomico, Somerset, and Worcester counties may still see a stray shower, but the overall trend should be toward lower rain chances compared to Saturday. Ocean City and Assateague may stay cooler with more clouds at times, but Sunday looks more manageable than Saturday.
Sunday Evening
Sunday evening should continue to improve for many areas, but a few leftover showers or storms may remain possible early.
Western and central Maryland may still have an isolated shower or storm around during the early evening. Farther east, the Eastern Shore and beaches should trend drier with partly cloudy skies.
If you have Sunday evening plans, they look more favorable than Saturday evening, but it is still smart to check radar before heading out.
Temperatures This Weekend
Saturday will be warm and humid, but clouds and rain may keep temperatures lower than they would otherwise be.
Expected Saturday highs:
- Garrett County: 70s
- Allegany and Washington counties: upper 70s to lower 80s
- Frederick, Carroll, Montgomery, and Howard counties: lower to mid 80s
- Baltimore City, Baltimore County, Harford, Cecil, and Anne Arundel counties: lower to mid 80s
- Prince George’s, Charles, Calvert, and St. Mary’s counties: low to mid 80s
- Eastern Shore: upper 70s to mid 80s
- Ocean City and Assateague: upper 70s to around 80
Sunday may be a little warmer inland where clouds break up, with highs generally in the 80s for much of Maryland. The beaches should remain cooler, mainly in the upper 70s to around 80.
Beach Forecast
For Ocean City, Assateague, and coastal Worcester County, Saturday looks unsettled with showers and storms likely at times. It will not be the best beach day, especially during periods of rain, thunder, or heavier showers.
Sunday looks better, but still not perfect. A slight chance of showers may linger, especially earlier in the day, but there should be more dry time compared to Saturday.
Beach temperatures will stay cooler than inland Maryland, generally near the upper 70s to around 80.
If you are heading to the beach this weekend, Saturday looks like the day most likely to be interrupted by rain. Sunday is the better beach day, but still keep an eye on the forecast.
Chesapeake Bay & Boating Outlook
The Chesapeake Bay, tidal Potomac, rivers, and coastal waters should not see widespread advisory-level winds for most of the weekend, but thunderstorms are the main concern.
Any storm over or near the water can quickly create dangerous conditions, including lightning, gusty winds, reduced visibility, and choppy water.
Boaters should not focus only on wind speeds. Even if winds look manageable, storms can make conditions unsafe very quickly.
Saturday is the more concerning day for boating interruptions. Sunday looks somewhat better, but storms remain possible in spots.
Travel & Outdoor Plans
Saturday is the day most likely to cause delays or changes to outdoor plans.
If you have a cookout, sports tournament, festival, beach trip, yard work, graduation party, or outdoor event Saturday, have a backup plan. Rain may not last all day, but showers and storms could interrupt plans at times.
Sunday looks more usable, especially later in the day and farther east, but scattered storms remain possible.
For drivers, the main concerns are wet roads, sudden downpours, lower visibility, and ponding in poor drainage areas. This could affect I-68, I-70, I-81, I-270, I-95, I-695, I-895, Route 50, Route 301, Route 13, Route 40, Route 15, the Bay Bridge, and local roads across the state.
