At some point we have to accept summer in DC for what it is – warm & humid with an ever-present storm threat.

Express Forecast

FORECAST IN DETAIL

Tired of humidity-induced bad hair days? We have just two more left (today and tomorrow) before a bit of a break. Now don’t get me wrong – it will still feel somewhat humid Friday through the weekend, just not nearly as steamy as it’s been. Shower and storm chances stay on the medium to high side before the mugginess breaks, after which they drop but don’t disappear.

Today (Wednesday): It’s still sticky out there as temperatures rise toward highs in the mid-to-upper 80s under partly to mostly cloudy skies. A disturbance moving by overhead means a 30% chance of a morning shower, and a 50% chance of afternoon showers and thunderstorms. Winds come from the southwest near 10-15 mph. Confidence: Medium

Tonight: The shower and storm risk drops down to about 20% for the evening into the overnight, but then bumps back up to 40% toward morning. Otherwise, it’s mostly cloudy and muggy with lows in the low-to-mid 70s. Confidence: Medium

Tomorrow (Thursday): Scattered showers and thunderstorms are possible pretty much at any point during the day as a cold front approaches, and some could be strong to severe. The overall chance of getting wet at any given location is about 60-70%. It’s still humid with partly to mostly cloudy skies, variable winds and highs in the mid-to-upper 80s. Confidence: Low-Medium

Tomorrow night: Mostly cloudy skies and a 50% chance of showers stick around through much of the night as the cold front pushes through. Skies may partially clear toward morning as lows bottom in the upper 60s to low 70s. Confidence: Medium

A LOOK AHEAD

Friday, Saturday and Sunday we’re on the less humid side of the cold front, which means low-to-moderate humidity rather than high. But since the front may linger not too far to our south and east, we’ll have to keep a 20-30% chance of a shower or storm in the forecast each day. Daytime skies should be partly sunny through the period with Friday and Saturday highs in the mid-to-upper 80s, and Sunday highs in the upper 80s to near 90. Confidence: Low-Medium
