8:40 pm update: Another batch of showers and isolated thunder coming from the west should move east across the area through around 10 p.m..
5:40 pm update: Showers and storms have dissipated and moved well east of the area. Could be more later this evening but local radar is quiet for the time being.
Through Tonight: Scattered showers and storms probably disrupt the commute home at least in some spots, with an overall 50% chance of a shower or storm at any given location into this evening. A few storms could turn severe with damaging winds and large hail. Of course, heavy rain and lightning are a threat with any storms that develop. Any showers and storms die down late in the evening or overnight and lows are mild and muggy, in the mid-to-upper 60s.
Tomorrow (Wednesday): Lately, once our weather gets into a pattern it has a hard time getting out of it. That’s the story tomorrow, which shapes up much like today and the past few. Highs aim for the mid-80s with partly sunny skies, and it’s somewhat humid with shower/storm chances a bit lower than today, around 30% and mainly mid-afternoon into evening.
Pollen update: Walter Reed says “Trees are in the MODERATE range at 67.73 gr/cubic meter, grasses are HIGH at 24.6 gr/cubic meter, weeds are LOW at 4.15 gr/cubic meter and mold spores are in the MODERATE range at 9181.99 spores/cubic meter.”

4:55 pm update: Severe T’storm Warning for northern Howard and southern Carroll counties until 5:15 p.m. This storm could contain quarter-size hail and winds over 60 mph. Meanwhile, a strong cell (not severe so far) has developed along the southern branch of the Beltway near Alexandria, heading east-northeast through southeast D.C. & central P.G. County.
From 3:15 p.m.: Highs have reached the mid-to-upper 80s and a few storms are popping up to the west, including in north-central Loudoun County approaching Leesburg and west-central Montgomery County, as well as in southern Fauquier into Stafford counties. Sounds a lot like yesterday, no? And like yesterday, while the area is not under a Severe Thunderstorm Watch today (except for Stafford, Charles, Calvert counties and points south), a few storms this afternoon into evening could be strong to severe.
