Rain chances, cooler weather returns to Maryland by mid-week
It feels more like late summer than October across Baltimore and much of Maryland right now, but some big changes are just around the corner.
Warmer air and a touch of humidity will stick around through Tuesday before a strong cold front sweeps through, bringing much-needed rainfall and a noticeable drop in temperatures.
Warm Weather in Maryland Early This Week
Overnight tonight, expect partly cloudy skies with lows dipping into the mid-50s to low 60s around central Maryland. Patchy fog could form in sheltered valleys and near the Bay, but most areas will stay clear.
Rain Returns to Maryland Tuesday Night
By Tuesday, clouds increase ahead of a strong cold front sliding in from the west. Baltimore and much of Maryland should stay dry through much of the day, though western Maryland could see a few early showers. The main rain arrives Tuesday night into early Wednesday morning, bringing a healthy soaking across the state.
Most areas will see a quarter to .75" of an inch of rainfall, and some models suggest locally higher totals up to an inch. Storms are not expected but a rumble of thunder can't be ruled out. This rain will welcome given the recent dry stretch and ongoing drought concerns in parts of the state.
Cooler Maryland Weather by Midweek
Once the cold front clears by midday Wednesday, the air turns much drier and noticeably cooler. Highs will only reach the mid to upper 60s around Baltimore Wednesday afternoon, with even cooler readings in western Maryland. By Wednesday night, clear skies and calming winds will allow temperatures to tumble into the 30s and 40s. Frost is a real possibility across western Maryland, especially in valleys and higher elevations.
Looking Ahead: Weekend Coastal Low a Question Mark
Thursday and Friday bring a stretch of crisp, dry fall weather, with highs in the 60s and chilly nights. But eyes then turn to the southeast coast, where a developing low pressure system could track northward along the Eastern Seaboard this weekend.
The exact path is still uncertain—some scenarios keep it offshore, while others bring it closer to Maryland. If the system hugs the coast, it could bring gusty winds along the Bay, coastal flooding concerns, and periods of heavy rain. If it stays out to sea, impacts will be minimal. Either way, it's a system to keep a close watch on.
