Baltimore and Washington, DC, are looking at a variable weather pattern this week, with a mix of clouds, sun, and warmer temperatures ahead. The National Weather Service Baltimore MD/Washington DC notes that the high-pressure system from New England is steering the weather, wedging down the East Coast today before drifting off Tuesday.
Ahead of this shift, the conditions over Baltimore include patchy low clouds due mainly to onshore flow. These clouds might hold back the temperature highs or could dissipate, leading to a split-the-difference scenario in the forecast. Tonight, areas could see more low clouds and a chance of fog, with overnight lows staying milder, in the mid-40s to mid-50s, escalating to gusts over 30 mph at higher elevations, according to a National Weather Service report.
For Tuesday through Wednesday night, the weather springs up with forecast temperatures in the 70s, even touching the 80s in certain areas. However, some uncertainty persists regarding persistent low-level moisture, which could put a slight hold on temperature climbs. The week's peak seems pegged for Wednesday, with projected highs that could push past the standing record daily warm temperatures for November.
As the week progresses, a cold front on Thursday brings a potential for sprinkles, especially along the Alleghenies. Following the front's passage, Friday is expected to see drier conditions with high pressure taking over from the central CONUS. Through the weekend, temperatures will tilt cooler, with most highs swinging in the 60s. The weather service indicates a small chance of a few light showers when the front encroaches Wednesday into Thursday night, with minimal coverage expected mainly along the mountains due to a westerly upslope flow.
The outlook for mariners indicates that a light easterly flow over the waters will turn southerly by Tuesday, with a possibility of near-advisory level wind events. Waters will likely require advisories Tuesday afternoon as winds pick up. While the tidal surges may push some locations to the action stage today, the general expectation is that conditions will relax below such levels midweek.
