9:40 p.m. update: The earlier severe thunderstorm warning ended and no additional one was issued. The storm activity has weakened somewhat, but lightning and heavy rain are still likely as it passes the immediate area over the next hour or so. This all moves east afterward, with perhaps another round of showers and perhaps a rumble near and after midnight.

9:01 p.m. update: A severe thunderstorm warning is up for parts of the western suburbs. Strong damaging winds are possibly occurring near Manassas and headed east with this storm. Showers and storms are moving across the area from west to east, focused on the southern half of the area. This should continue for the next hour or two, with most storms staying below severe limits.

From 4:45 p.m...

Today’s weather was considerably subdued by abundant cloud cover. Highs in the low and mid-80s came after some midday rain that cooled the area back into the 70s. While we’ve seen some late-day sun, especially west, it is probably too little to give a huge boost to storm chances. We do need to keep an eye out into and through the evening, just in case.

Through tonight: Clouds continue to break for a time this evening. We may still see some showers or storms kick up or move by, especially in western parts of the area toward the Potomac and then into Southern Maryland. The most significant activity should remain to the south. Additional showers may pass late night as humidity remains high. Lows settle largely in the range of about 70 to 75. Some patchy fog may develop as winds go light.

Tomorrow (Wednesday): There are a lot of clouds around and probably some showers. Nothing seems likely to amount to much. We should see some clearing in the afternoon. Highs reach for the mid-80s, with perhaps some upper 80s. Given high levels of humidity, with dew points in the 70s, it will feel more like the low 90s or so. Winds are variable but turning to the north with time.
