Good evening, Maryland. If tonight feels different from the soup we were wading through last week, that’s because it is — NWS Baltimore/Washington (2:46 PM update) and NWS Wakefield (3:07 PM) both confirm a drier, cooler airmass has settled in behind departing high pressure over the Great Lakes. Dew points have crashed into the comfortable 50s and low 60s, skies are clearing out, and there’s genuinely nothing to worry about weather-wise tonight statewide. The only real story is a couple of Coastal Flood Statements for minor tidal flooding along the lower Eastern Shore and Worcester County beaches, tied to that lingering onshore flow and an elevated high tide cycle.
Tonight’s Timeline
- Evening (7–10 PM): Clearing skies statewide, temperatures falling comfortably, light north-to-northeast breeze.
- Late Evening (10 PM–Midnight): Any lingering high-tide coastal sloshing on the Shore should ease as tide recedes; inland areas turn crisp and dry.
- Overnight (Midnight–6 AM): Mostly clear to partly cloudy, patchy fog possible on the Lower Shore toward dawn. Lows bottom out in the 50s inland, 60s toward the Bay and coast.
- Monday Morning: A refreshingly cool start — feels like early fall for an hour or two before the sun takes over.
Region by Region
Western Maryland
Garrett County (Deep Creek/Oakland): Mostly clear, light easterly winds around 5 mph, low near 51° — genuinely chilly up in the highlands tonight, grab a blanket if you’re camping. Allegany County (Cumberland): Mostly clear, low around 56°, light north winds. Both counties see essentially 0% rain chance — as clean a night as you’ll get.
Northern & Central Maryland
Washington County (Hagerstown): Mostly clear, low around 57°, northeast wind 3-7 mph. Frederick CountyCarroll County: Mostly clear, low around 59°, light north wind 2-6 mph. Dry as a bone across the whole corridor — a fine night for stargazing if you’re away from town lights.
Baltimore Metro
Baltimore City & County, Harford, and Howard: Mostly clear, low around 64°, northeast winds 2-7 mph, essentially no rain chance. Anne Arundel County: Same story, low around 64°, though keep an eye on the Bay shoreline near Annapolis — see the tidal note below.
DC Suburbs
Montgomery and Prince George’s counties: Partly cloudy early, clearing out overnight, low around 63°, light and variable winds. A slight 4% pop is essentially just meteorological fine print — don’t expect to get wet.
Southern Maryland
Charles, Calvert, and St. Mary’s: Mostly clear, low around 64°, northeast winds up to 7 mph near the water. Comfortable, quiet night along the Patuxent and Potomac shorelines.
Upper Eastern Shore
Cecil, Kent, Queen Anne’s, Talbot, and Caroline counties: Mostly clear, low around 60°, light easterly winds. A slightly higher 7% pop reflects a stray sprinkle chance near the Bay, but nothing organized.
Lower Eastern Shore
Dorchester, Wicomico, and Somerset counties: Mostly clear early, then patchy fog developing toward daybreak, low around 62°, northeast winds 2-7 mph. This is also where the Coastal Flood Statement is in play — see Active Hazards below.
Ocean City & the Coast
Worcester County: Mostly clear, low around 67° — the mildest overnight low in the state, courtesy of that onshore flow. Winds northeast 6-10 mph. Surf around 2 feet, rip current risk currently Low tonight but NWS Wakefield flags it building to Moderate for Labor Day as onshore winds and nearshore waves increase — swimmers should be mindful heading into tomorrow. Water temp holding near 80°.
Active Hazards
Coastal Flood Statement (Minor): In effect for inland Worcester County and the Maryland beaches (Ocean City/Assateague), tied to elevated tidal anomalies from persistent onshore flow. Coastal Flood Statement (Minor): Also in effect for Dorchester, Wicomico, and Somerset counties on the Lower Shore. Expect minor nuisance flooding of low-lying shoreline roads and docks around the high tide cycle — nothing widespread or dangerous, but know your low spots if you’re near the water. NWS Baltimore/Washington also flagged that minor tidal flooding is becoming increasingly likely at Annapolis and other sensitive spots in the northern Chesapeake Bay; an advisory there is possible later tonight if the trend holds, though none was in effect as of this afternoon’s update.
Severe & Flooding Threat
None tonight. This is about as low-drama a forecast as Maryland produces — dry, clear-to-partly-cloudy, and quiet across all 23 counties and Baltimore City. The next legitimate threat to watch is mid-to-late week (details below).
Heat, Humidity & Winds
Humidity remains refreshingly low tonight — dew points in the 50s to low 60s statewide, a welcome break after last week’s mugginess. Winds are generally light, 5-10 mph out of the northeast, with slightly breezier conditions expected at Ocean City into Labor Day as onshore flow strengthens.
Chesapeake Bay & Marine
No marine hazards expected through the holiday weekend, though onshore gusts flirted with marginal Small Craft Advisory levels late this afternoon — NWS Baltimore/Washington favored a Marine Weather Statement given the brief duration rather than a formal SCA. Northeast winds tonight shift southerly by Tuesday, staying below SCA thresholds. Boaters on the Bay should watch that Annapolis-area tidal trend mentioned above.
Overnight Lows by Zone
| Zone | Low |
| Western Mountains (Garrett) | Around 51° |
| Cumberland/Hagerstown | 56-57° |
| Frederick/Carroll | Around 59° |
| Baltimore/DC Corridor | 63-64° |
| Southern Maryland | Around 64° |
| Eastern Shore (Upper/Lower) | 60-62° |
| Ocean City | Around 67° |
Looking Ahead
Labor Day (Monday): Sunny to mostly sunny and pleasant statewide, highs mostly low-to-mid 80s inland (upper 70s to low 80s Western Maryland, mid-70s Ocean City with a stiffer onshore breeze). Lower humidity holds. Rip current risk builds to Moderate at the coast — swim near a lifeguard. Tuesday: Similar dry, seasonable pattern, highs mid-80s inland, upper 70s at the beach. Wednesday into Thursday: Humidity and temperatures creep back up ahead of an approaching cold front, with highs potentially reaching the upper 80s to near 90 by Thursday. Showers and thunderstorms look possible Wednesday evening into Thursday as the front tracks through — timing and severe potential remain uncertain, but there’s at least some risk of stronger storms given available instability and possible wind shear. We’ll have much better detail as the week goes on.
