Baltimore residents can anticipate a refreshing break from the sweltering summer heat, as a Canadian high-pressure system moves in to deliver cooler-than-average temperatures for the remainder of the week, the National Weather Service Baltimore MD/Washington DC indicates. Today's highs will settle in the mild 50s and 60s in the elevated western mountains, while the rest of the area, stretching east to the Chesapeake Bay, will see lower to middle 70s.
The arrival of this high pressure is set to ensure dry conditions prevail, and a drop in tonight's lows into the 40s in the Appalachian mountains and lower to middle 50s to the east might require some to pull out a blanket. Temperatures along the shoreline of the Chesapeake Bay and Tidal Potomac are anticipated to hold in the lower 60s. Thursday and Friday are poised to sustain the cool temperature trend, with the arrival of a cold front on Friday potentially stirring up a spatter of showers, or even the odd thunderclap, though the occurrence of which seems sporadic at best.
Looking forward to the weekend and beyond, the weather pattern remains pleasantly constant, as high pressure continuously lords over the mid-Atlantic, ushering in a series of sunny to mostly sunny days, accompanied by below-average temperatures consistently hovering in the 70s, save for some higher elevations where 60s will be more common, with isolated spots possibly reaching the low 80s especially in metro areas and valleys, reports the National Weather Service.
As for aviation and marine outlooks, conditions seem smooth sailing through to the weekend: pilots can expect VFR conditions, light winds, and mostly cloud-free skies making for clear visibility, while those out on the Chesapeake Bay and Tidal Potomac should notice winds picking up slightly into a small craft advisory early today before calming and then possibly rising again Thursday into Friday morning, as gleaned from the National Weather Service Baltimore MD/Washington DC announcement.
