9:30 p.m. update: Severe thunderstorm warnings have expired, but storms with heavy downpours and lightning are pushing through Charles County. These will continue pushing east towards the Bay and should gradually weaken over the next hour or so.

These storms were incredibly picturesque both as they approached and departed. We will have some awesome pictures to share with you tomorrow!

A sneak preview:

7:45 p.m. update: A severe thunderstorm warning is in effect until 8:45 pm for southern Fairfax County. Other warnings could be issued as storms track east-southeast across the D.C. metro area through around 9:30 p.m. These storms are capable of damaging 60 mph wind gusts and hail as well.

From earlier… Thursday was basically a replay of Wednesday, as high temperatures once again rose to near 90. With fairly high humidity for this time of year, it’s feeling rather unpleasant out there. We’ve got some more high heat to get through before this first stretch of summer-like warmth comes to a close.

Through tonight: A few storms that popped up over the hills to the west will try to work through parts of the area heading through the rest of the afternoon and into the evening. There’s a chance more may develop as well, but this activity should remain isolated, and it’ll wane as the sun sets. Otherwise, mostly clear to partly cloudy skies are the rule. There’s a sizable range in temperatures tonight, from the mid-and-upper 60s in the “cool” spots to perhaps as high as the mid-70s in the city.

Tomorrow (Friday): We’re stuck in this same routine for at least one more day. That means a muggy and hazy morning turning into a hot and humid day. Clouds are probably a bit more numerous overall, but partly cloudy at most for much of the day. Highs end up right around 90 most spots. An isolated late-day storm or two is possible, and it could be strong to perhaps severe.

Storm Prediction Center outlook for Friday. (NWS)

Friday storms: The Storm Prediction Center has us under a “marginal risk” of severe weather tomorrow. Here’s what they have to say about it:

The environment probably will become at least conditionally supportive of thunderstorms with at least some severe wind/hail potential, but this seems likely to occur largely in the presence of rising mid-level heights beneath building upper ridging. Although a belt of modest westerly mid-level flow initially over the middle Mississippi into lower Ohio Valley early in the period seems likely to weaken, it might not be out of the question that related perturbations provide support for renewed thunderstorm development Friday afternoon and evening.
