FORECAST IN DETAIL

Considerable clouds probably keep today and tomorrow from being as hot as they could’ve been. Instead of mid-90s or more, it’s more like near 90 to low 90s for highs but with a boatload of humidity. All in all, the forecast right through the weekend is about as typical as you get for summer in the D.C. area, which is to say plenty warm and plenty humid with the occasional threat of a heavy shower or thunderstorm.

Today (Wednesday): Super muggy and partly to mostly cloudy. That’s the scene as highs head for near 90 to the low 90s with afternoon heat indices into the mid-90s. Maybe a passing shower through early afternoon, with a better chance (50%) of showers and thunderstorms mid-afternoon into evening. Any storms are likely slow-movers, and with the moisture-rich atmosphere could produce very heavy localized rain and strong wind gusts. Confidence: Medium

Thundercast:

Probability: 50%
Coverage: Scattered
Most likely timing: 3-10 p.m.

Tonight: Scattered showers and thunderstorms spell a 50% chance of rain at any given location through mid-evening, then decreasing chances as we get into the late evening and overnight. Skies remain partly to mostly cloudy and the humidity stays thick with lows around 70-75. Confidence: Medium

Tomorrow (Thursday): Still humid out there but should be less so than today. After the slight risk of an early-morning shower, partly sunny skies help highs to around the same range as today, near 90 to the low 90s, with a 30% chance of afternoon/evening showers and storms. Confidence: Medium

Tomorrow night: A cold front passing through keeps alive a 30% chance of showers and storms. Skies should be partly cloudy as lows settle to the upper 60s to low 70s. Confidence: Medium

A LOOK AHEAD

Friday through Sunday continues partly sunny, warm and moderately humid with highs in the mid-80s to low 90s. The cold front may still be close enough to spark a shower or thunderstorm at pretty much anytime, with the best chance focused on the late afternoons through early mornings. That said, the overall chance of rain is only about 30% each day, and there should be plenty of rain-free periods. Confidence: Medium
