Baltimore residents can look forward to seasonable temperatures and low humidity continuing through Friday, as reported by the National Weather Service Baltimore MD/Washington DC. In their latest Area Forecast Discussion, a wedging high-pressure system from the north is expected to maintain the current pleasant weather conditions before temperatures start to rise over the weekend and into early next week.
For those making plans, the near-term forecast holds good news with mainly clear skies expected tonight, except for occasional high thin clouds. High pressure centered over Quebec is set to build southward into Friday morning, touching down over the Lehigh Valley of eastern Pennsylvania. By today, southeasterly winds will invite scattered stratocumulus clouds, although they should dissipate as the night draws near.
The weekend forecast allows for a shift in the high-pressure center offshore, leading to southerly winds and a modest temperature increase, with Saturday highs possibly reaching the mid to upper 70s. According to the National Weather Service, this slight warming trend is part of a fair-weather system that boasts limited cloud cover.
Looking further ahead, upper-level ridging will continue to dominate through Tuesday, the National Weather Service added, forecasting normal to slightly above normal temperatures east of the mountains. With high pressure sitting just off the coast, expect dry conditions, partly cloudy to mostly sunny skies, and a slight uptick in humidity. The anticipated warmth includes high temperatures pushing into the upper 70s and low 80s, while overnight lows will slowly climb from the mid to upper 50s on Sunday night into the low and mid 60s by Tuesday night.
Aviation operations seem to be in for a smooth ride, seeing no significant weather disruptions through the early part of next week, with VFR conditions expected. Mariners, on the other hand, after experiencing recently diminished winds, will find no marine hazards expected through Tuesday morning. However, small craft advisory conditions could arise with a cold frontal passage expected from Wednesday into Wednesday night.
Tides and coastal flooding concerns are also on the radar; moderate coastal flooding at Annapolis is projected to persist through Thursday night's high tide cycles, prompting the extension of a Coastal Flood Warning. The rest of the region is looking at continuing minor coastal flooding into Friday morning before water levels start to recede.
