5:20 p.m. update: The thunderstorm rolling through the Beltway has weakened slightly and it is no longer severe. It still has plenty of heavy rain and lightning, though, and we’re getting a few isolated reports of tiny hail in areas around Silver Spring.
There’s a train of storms lined up to the southwest and we expect these will continue to move east over the next few hours. A couple severe thunderstorm warnings could be issued, especially in our southern areas. Models suggest this line of storms will clear the area by 8 or 9 p.m., but showers could linger behind for an hour or so.
The Nationals game does look like it will be impacted by rain — a delay seems likely at this point, but the back edge of the rain should move out in time to get things started (eventually).
4:25 p.m. update: A severe thunderstorm warning has been issued for some of our near western suburbs and NW DC. The warning is in effect until 5 p.m. but it could be extended eastward in the next 30 minutes. This storm is producing gusty winds and possibly some small hail. Most notably, though, will be the heavy downpours. Head inside now if you want to stay dry!

FORECAST IN DETAIL
This weekend cool-down isn’t looking like it will amount to much. A cold front that dropped into the area last night is settling in for a stay. It’ll actually mostly fall apart overhead. But first, it might spark up some late-day showers and storms. It seems quite likely we’ll keep piling on 90s up ahead.
Today (Saturday): It’s another hot and humid one. Standard July. There could be a very early shower from remnant overnight activity to the west. Otherwise, skies start off partly to mostly sunny, but that muggy air percolates as the day goes. This means clouds should tend to increase noticeably by the afternoon, and a risk of showers and storms picks up in the mid-afternoon to before dinner time frame. High temperatures are near 90 in the cooler spots to the low 90s elsewhere. Winds are from the south and southwest around 5-10 mph. Confidence: Medium-High
Tonight: A shower and storm risk may last through about 10 p.m. or so before dwindling in the overnight. With plentiful moisture in the air, temperatures don’t go too far, reaching overnight lows in the upper 60s to lower 70s. Skies trend partly to mostly clear late, and there could be a random spot or two of fog by dawn. Confidence: Medium-High
Tomorrow (Sunday): The front in the area washes out even further while also drifting a bit to the south. This means more sun and less in the way of storm threats. With dew points still right around 70 degrees, humidity remains pretty close to the oppressive line. Keep the water handy if outside, as highs rise to near 90 or even into the mid-90s. Winds are from southwest around 5 to 10 mph. Confidence: Medium-High
Tomorrow night: It’s a tranquil evening for outdoor plans, and it stays that way through the night. Dew points are back into the mid-60s or so, which helps temperatures fall into the 60s for much of the area. An exception might be downtown where low 70s are more likely. Skies are partly cloudy. Confidence: Medium
A LOOK AHEAD
Despite the next cold front beginning to approach from the northwest, Monday is rather sun-filled. Lots of sun and some downsloping (warming) wind off the mountains should equal another scorcher. Highs are mainly in the low and-mid 90s. There could be an isolated to scattered shower and storm threat in the afternoon, but the main impact from the cold front seems to want to hold off until Tuesday. Confidence: Medium
Following sticky 70s for lows, that cold front pushes through the area on Tuesday. The timing is a bit uncertain from this range, but it should try to touch off some showers and storms as it moves by. If it holds off until late in the day, those storms could be strong. Highs head for the low 90s. Confidence: Medium
