We should then see a break before shower and storm chances rise again later this afternoon. See our full forecast below for more details…

After yesterday’s mid-90s swelter and strong to severe evening thunderstorms, we settle into a more typical summer pattern over the next several days. We’re talking warm and somewhat humid, but nothing super hot or oppressive. The best chance of showers and storms comes with a cold front crossing the area today, but even into the weekend we have a hard time ditching rain chances completely.

Today (Wednesday): It’s become a familiar midweek forecast and here we go again with partly sunny skies, warm and fairly humid conditions, and a 40-50% chance of showers and thunderstorms. Can’t rule out something earlier, but the best chance of showers and storms looks to be after 3 p.m. or so. A few storms could be strong to severe with damaging winds and hail, especially south and southeast of the District. Afternoon highs should top out right around 90 with breezes near 10 mph from the southwest. Confidence: Medium

Tonight: With the front still around, we’ll hold on to a 40-50% chance for scattered shower and storms through around midnight. Any showers and storms should diminish thereafter as overnight lows drop to the mid-60s to low 70s. Confidence: Medium

Tomorrow (Thursday): High pressure centered to our north or northwest tries to suppress showers and storms to our south and southeast. It may well be quite successful in doing so, but to be safe let’s allow for a 30% chance of showers and storms mainly in the afternoon into evening. Skies are partly sunny again and it’s perhaps a bit less humid, with highs in the mid-to-upper 80s. Confidence: Medium

Tomorrow night: That pesky front could still be close enough for a slight chance of a shower or thunderstorm during the evening or overnight. Temperatures find themselves in familiar territory with lows in the 60s to near 70. Confidence: Medium

A LOOK AHEAD

Friday shower and storm chances are down but not out. The atmosphere could remain unsettled enough for a 30% chance of a few showers or storms at some point during the day. Humidity still shouldn’t be too bad as highs reach the mid-to-upper 80s under partly sunny skies. For now at least, I think we can leave rain chances out of the forecast for Friday night with lows back down to the mid-60s to near 70. Confidence: Medium

The weekend doesn’t look as beautiful as we’ve gotten used to, but doesn’t look too bad either. Skies continue partly sunny with an isolated shower or storm possible each day. Highs head for the upper 80s to low 90s, probably the lower end of that range for Saturday and the higher end for Sunday, with moderate humidity throughout. Upper 60s to low 70s should do it for Saturday night lows. Confidence: Medium
