A shower could still bother. But the big news is less heat & falling humidity. That’s 2 steps in right direction. Get the Digit on Twitter| Discuss on Facebook


Well we’ve weathered the season’s first heat wave and now it’s back to more typical temperatures for the next several days, though we’re still on the warm side today. Most important, exiting with the heat is that sweaty humidity, which goes super low for a spectacular day tomorrow. Despite drier air moving in, we still face the potential for a lingering shower today and more showers and thunderstorms late Friday.

Today (Wednesday): Morning clouds and maybe an isolated shower (best chance south and east of D.C.) give way to partly sunny afternoon skies as highs reach the mid-80s. Even though drier air filters in during the day, we may still have enough moisture and energy left in the air for an isolated afternoon shower. Confidence: Medium

Tonight: Other than the chance of an isolated evening shower, it’s all about cooler and drier air. Lows are refreshing - near 60 to the mid-60s (suburbs to city) - beneath partly cloudy skies. Confidence: Medium-High

Tomorrow (Thursday): Ding-Ding-Ding! We have a winner. Thursday promises a fantastic weather day with mostly sunny skies, low humidity, a nice breeze from the northwest and highs near 80. Confidence: High

Tomorrow night: Our next weather system approaching from the Midwest sends partly cloudy skies our way with lows in the upper 50s to mid-60s. Confidence: Medium-High


The Friday forecast needs watching. But for now it appears that low pressure and an associated cold front will approach slow enough such that we see no more than an isolated shower through morning, with shower and thunderstorm chances increasing during the afternoon into Friday night. Highs should still get to the upper 70s to near 80 despite partly to mostly cloudy skies, followed by Friday night lows in the low-to-mid 60s. Confidence: Low-Medium

The main line of showers and storms should be gone by the time we wake up Saturday morning or shortly thereafter. I wouldn’t rule out an isolated shower either day of the weekend. But all in all we should have a decent Saturday and Sunday with partly sunny skies, highs in the mid-70s to low 80s, and Saturday night lows in the upper 50s to mid-60s. Confidence: Medium
