As the week unfolds, Baltimore residents can expect a shift in weather patterns, with a National Weather Service report indicating a series of cold fronts moving through the area. The first of these fronts will bring light rain to southern Maryland and locales along the I-95 corridor this morning, with a dry air mass to follow on Tuesday. Temperatures are expected to range from the 50s to 60s during this period.
Late this evening, a cold front is set to cross the region, pulling down temperatures into the 30s and 40s overnight. The wind will shift northwest, potentially leading to gusty conditions, particularly over higher elevation areas. A period of small craft advisory conditions is forecasted beginning at 7 PM this evening through 1 PM EST Tuesday for parts of Maryland, specifically the MDZ008 zone.
By mid-week, another cold front will pass, bringing a dry air mass that could pose fire weather concerns. According to the National Weather Service, Tuesday could be particularly dry with the winds and low relative humidity creating optimal conditions for wildfire spread, while Wednesday's southerly wind gusts of 20-30 mph could further complicate matters. Given the extended dry period, even recent rains may not be enough to mitigate the elevated wildfire risk.
The National Weather Service also points to a progressive high-amplitude pattern affecting the country for the remainder of the week, with impacts felt in Baltimore as another cold front is expected by Friday. This front may increase rain chances into Saturday. Additionally, frosts are possible on Thursday and Sunday nights, where the growing season persists, mainly along and east of I-95, potentially affecting sensitive vegetation.
Marine conditions will vary throughout the week with northwest winds this morning, and the cold front later today shifting winds to the northwest. Small Craft Advisories may be issued accordingly. The calm should return Tuesday night as the high-pressure system settles, before southerly winds preceding Wednesday's cold front potentially kick up gusts of 15-20 knots. Aviation conditions across most terminals will remain VFR, except for potential MVFR ceilings due to light rain affecting MTN, BWI, and DCA this morning.
