Baltimore is set to experience a variety of weather conditions starting today, with shower chances lingering through daybreak west of the Blue Ridge Mountains as the cold front makes its approach. As reported by the National Weather Service Baltimore MD/Washington DC, the front’s crossing today will bring with it more chances of showers and thunderstorms, ultimately leading to a drop in temperatures as we move into next week, thanks to a strong dome of Canadian high pressure building in the region.

Today's highs are expected to be "a tick or two below climo norms" with low to mid-80s for most and 70s in the Mountains, the National Weather Service forecasted, tonight's lows will descend into the mid-60s ahead of the front, with 50s behind the front in the Alleghenies, and while shower activities are anticipated to cease after the front's departure early Monday, winds might see a slight bump as high pressure builds from the Ohio River Valley. For those at high elevations, frost may be a hallmark of the impending autumn, signaling a turn of the season that clings to the crispness of the air.

The forecast for the short term of Monday through Tuesday night sees a less busy sky, but temperatures will continue to flirt with the cooler side. For most, temperatures on Monday will remain below average, scuttling into the range of 70s to near 80, and the first frost of the fall is expected in high elevation valleys and bogs come Monday night. Dryness persists as we enter Tuesday with even cooler nights, potentially leading to patchy frost in areas traditionally favored by the chill.

As we extend our gaze to the long-term forecast stretching from Wednesday through Saturday, the area will remain under the influence of the broad H5 trough from the Canadian Maritimes. High pressure from Ohio will settle atop the region, peaking on Thursday, leading to more potential frost conditions, particularly in higher elevations; meanwhile, residents can expect temperatures generally sitting 5 to 10 degrees below normal across the area, touching upon the upper 30s in the Potomac Highlands, and regarding precipitation the National Weather Service indicates chances remain around the lower threshold of 10 percent during this period, thus no significant weather impacts are expected beyond the cool-down.

Coastal flooding has been a theme for the area, with minor improvements forecasted as winds change after Monday and water levels begin to recede. While moderate coastal flooding is expected in Annapolis early Sunday, the general trend will point to a gradual lessening of conditions. Marine life finds reprieve as well, with sub-SCA level winds expected today and no marine hazards from Tuesday through Thursday. For Baltimore and the wider region, nature's breath seems lighter with the passage of each day, laying a gentle hand upon the waters and the skies above.
