PM Update: Showers, Flooding to Subside
Moist flow off the ocean interacting with a warm front draped over the region brought frequent and sometimes intense showers to the area overnight and this morning, causing localized flooding in some areas, particularly in Montgomery County. Showers diminished this afternoon and should be sparse for the drive home.
Through Tonight: Showers should be few and far between through the commute. More rain could threaten this evening, though much of it may be confined to areas west of the Beltway, before rain chances wane toward dawn. Cloudy skies linger overnight and patchy morning fog is possible as temperatures remain steady -- mainly near 60.
Tomorrow (Wednesday): A wind from the south/southeast will elevate temperatures back to normal levels, with highs in the mid-70s. Can't rule out upper 70s to near 80 if the sun can put a bigger dent in the mostly cloudy skies than we're currently anticipating. By late afternoon and early evening, there's a 40% chance of some isolated showers and thunderstorms -- likely less numerous than earlier today.

Flooding Rain: Two to four inches of rain has fallen since yesterday in many parts of the D.C. metro area, enough to cause some flash flooding.
In Montgomery County, a flood warning remains in effect for Seneca Creek (near Dawsonville) and Rock Creek (at Sherrill Dr.), where flood waters are expected to crest between 8 and 9 feet this afternoon. A Flood Watch is in effect for the entire region until tomorrow morning. (Flood Warnings and Watch have been cancelled.)
