D.C.-area forecast: The start of May will feel more like March.

First full week of May might end up cooler than any April week.

Express forecast
Today: Partly to mostly cloudy, windy, possible shower. Highs: 55 to 59.
Tonight: A shower or two and brisk. Lows: Mid-40s.
Tomorrow: Variably cloudy, breezy, possible shower. Highs: 54 to 58.


Much of April was mild, but temperatures have gone into reverse since last week. The first full week of May might end up cooler than any April week. Highs probably struggle to top 60 until Thursday or Friday. The payoff should be a delightful spring weekend with highs closer to 70. We’re not expecting a ton of rain this week but we’ll have a chance of a shower or two, mainly in the afternoon, today through Thursday.

Today (Monday): Partial sunshine may be with us during the first half of the day but clouds should become more numerous in the afternoon. A shower or two could pop up, and a little small hail could accompany any heavier showers. Highs are only in the mid- to upper 50s and it feels even chillier as winds from the southwest blow at 10 to 20 mph with some gusts of 20 to 30 mph. Confidence: Medium-High

Tonight: Skies remain mostly cloudy and there could be a shower or two, especially north and northwest of the Beltway. It remains breezy and cool, with lows mostly in the mid-40s. Confidence: Medium-High

Tomorrow night: Shower chances decrease after sunset with partly cloudy skies overnight. Lows are very chilly, dipping into the upper 30s in our colder areas and low 40s downtown. Confidence: Medium-High
