7:15 p.m. update: The storms are continuing to steadily weaken in the Silver Spring to Bowie corridor and are on the verge of collapse. By sunset, everything should be over or about to end. But continue to watch out for areas of high water near creeks and streams and don’t cross any flooded roads in your cars. Even as the rain is ending, the Weather Service issued a flash flooding warning for parts of the area (northeast D.C., southeast Montgomery and northwest Prince George’s County) that witnessed up to 2 to 3 inches of rain because streams and creeks are rising:
This is the last update on this (frankly unexpected) storm outburst. Scroll down for the outlook through tomorrow.
7:00 p.m. update: There are signs the storm that trudged through the District and is dumping heaving rain between Silver Spring and Bowie is starting to weaken some. Even so, it is a slow mover so areas which have standing water and/or are flooding may continue to be stressed for another hour or so. Doppler radar indicates up to 2 inches of rain has fallen east and southeast of Takoma Park and we have seen reports of a few areas with high water. These storms should continue to weaken and drift slowly northeast heading toward sunset.
6:25 p.m. update: A flood warning has been issued for the District, southeast Montgomery County, and northwest Prince George’s County until 12:15 a.m. Up to one inch of rain has fallen in this zone, and another one to two inches is possible – especially east of the District, where the heaviest rain is now focused. Remember, don’t try to drive across a flooded road and stay away from creeks and streams during these downpours.
6:20 p.m. update: The torrent over NW D.C. is starting to diminish but the storm has blossomed to the east and northeast, prompting a severe thunderstorm warning for NE D.C., southeast Montgomery County and northwest Prince George’s County until 7 p.m. Heavy rain and lightning are the main hazards with this storm, but an isolated damaging wind gust cannot be ruled out.
6:00 p.m. update: Storms have been isolated, but unfortunately for those in the city isolated means right overhead. Very heavy rain has fallen over parts of the District for the last hour or so as a storm stalled out locally. At least localized flash flooding is possible with this cell until it dies off, especially near creeks and the like.
From 4: 45 p.m…
Typical conditions for early August greeted the month around here. Certainly nothing too remarkable about the day, but it was also toasty and fairly muggy. A few lucky locations saw some raindrops offering respite, while most other spots spent the afternoon near 90. Our weather remains largely quiet through tonight and into Wednesday.
Through tonight: A random shower or storm is possible into the sunset period. Overall, puffier clouds that bubbled up in the heating of the day dissipate, although high cloudiness continues to swing through and may occasionally obscure the sky through the night. Lows mostly dip to the mid-60s in the coolest suburbs and range as high as the low 70s in the city.

Tomorrow (Wednesday): No major changes in the pattern are in store, so it’s another near-average type of day for midsummer. High clouds may continue to float by, and some of those cumulus clouds will percolate. Maybe an isolated shower or storm, but nothing worth worrying much about. Highs are mainly in the near-90 to low 90s zone as winds blow in from the south about 10 mph.
Summer doldrums: We’re into the time of year where a day near 90 and a few storms has been the forecast for weeks. It was day 32 of 90-plus high temperatures in Washington today. Despite a short break from the heat barrage over the past week, we’re now about a week to 10 days ahead of normal to date.
With the one-minute meso sector parked over the D.C. area today and the clear skies overhead through the morning into the lunch hour, it was possible to spot heat islands on satellite. This heat is good for something!
Typically from here through the end of the season, the city piles on about two more weeks of 90-degree days. We’ll hope that’s not the case this time, although the forecast for August and fall seems warm. Surprise, surprise.
