“Unsettled” would be a good word to describe this forecast period. With a frontal system stalling out across the mid-Atlantic today, a wave of low pressure tomorrow, and a stronger frontal system Tuesday into Wednesday, there isn’t much hope for sunny skies or long stretches of dry weather. Several periods of showers and rain are in the forecast, along with the chance for some drizzle or mist as well. The midweek front should usher in a drier and sunnier pattern for our late week.
Today (Sunday): With a cold front draped across the region, much of today is gray, cool and damp. The best chance for showers of any significance (mainly light to moderate intensity) comes during the morning through around 1 p.m. or so, although a few light showers or some drizzle could linger later into the afternoon. Clouds may thin a bit toward sunset, but it’s a mostly cloudy day on the whole with temperatures mainly steady in the upper 40s to low 50s. A light wind blows from the north around 10 mph. Confidence: Medium-High
Tonight: High pressure tries to build in behind the front and should dry us out a bit overnight, though skies probably stay partly to mostly cloudy. With the front still nearby to our south, some of our southern or southwest burbs may still see some fog or drizzle overnight, but most everywhere else should stay dry. Overnight lows drop into the mid-30s to near 40 as winds remain out of the north at 5-10 mph. Confidence: Medium-High
Tomorrow (Monday): A wave of low pressure forms and moves along the front stalled to our south. Most of the rain associated with the low should stay south or our area. But we do have a 50% chance for mainly light showers south of the Beltway, with only a 20% chance or so elsewhere. That being said, with winds turning more from the northeast, there is an increased chance area-wide for some fog or drizzle. Skies stay mostly cloudy with highs likely stuck in the mid-40s to near 50. Confidence: Medium
Tomorrow night: Clouds cover up the stars once again during the evening, with that continued chance of drizzle or mist. Shower chances then increase to around 60% during the overnight hours, with temperatures fairly steady in the 40s. Confidence: Medium
Tuesday into Wednesday brings a good chance of occasional showers, first with a warm front and then with a cold front. There’s little change in scenery as far as the mostly cloudy skies are concerned, with highs both days in the 50s. Tuesday night lows only drop back to near 50. Confidence: Low-Medium
