*Flood watch in effect through this evening*
10:30 a.m. update: Storm rainfall totals as of 10 a.m. are 1.97″ at Reagan National, 0.97″ at Dulles, and 1.89″ at BWI. But an even more whopping 2.8″ has fallen thus far at Andrews Air Force Base (just southeast of the Beltway). Flood warnings continue for Manassas and Prince William County, as well as parts of southern Prince George’s, southwest Anne Arundel, and northwest Calvert counties.
Even as rain tends to become more scattered this afternoon, pockets of heavy rain may continue to cause flooding.
8:30 a.m. update: 1.84 inches of rain have fallen at Reagan National Airport since yesterday, and perhaps another half inch could fall today. Rain may become a bit more showery/spotty this afternoon. Radar still shows plenty more rain headed our way.
A flood warning has been issued until noon for Manassas and Prince William County, where more than two inches have already fallen. Do not try to drive across a flooded road.

FORECAST IN DETAIL
Our soggy saga continues through the day, after yesterday’s 1.06 inches at Reagan National Airport broke the previous record for the date of 0.81 inches, which occurred in 1881. At least we’re looking at a milder afternoon, with some spots heading near or past 60. The workweek should be a good deal drier, although a few light showers or spotty areas of wintry mix may linger. Temperatures take us for a ride, trending colder tomorrow and especially Tuesday, before warming again midweek.
Today (Sunday): The morning hours feature more rain, moderate at times, as it continues to train southwest to northeast along a front draped across our region. We’ve still got showers through the afternoon, but they should become somewhat more intermittent. Total rainfall ranges from about one to three inches, with locally higher amounts possible. Warm winds from the south should push afternoon highs into the low to mid-60s for much of the region, though some areas north and west of Washington could hold in the mid- to upper 50s. Confidence: Medium-High
Tonight: Scattered showers remain possible as the front works its way through during the evening and overnight. Mostly cloudy conditions continue, even as overnight winds pick up from the northwest and start to scour this soupy air mass away. Expect lows down to the upper 30s to mid-40s. Confidence: Medium
Tomorrow (Monday): A few lingering showers can’t be ruled out through the course of the day. Otherwise, we’re mostly cloudy and considerably cooler, as a persistent breeze from the north helps cap highs in the mid-40s to near 50. Confidence: Medium
Tomorrow night: Colder and drier air continues to move in overnight, and most spots drop to below freezing. Clouds finally scatter enough for skies to be deemed only partly cloudy, with lows mainly in the upper 20s to low 30s. Confidence: Medium-High
A LOOK AHEAD
On Tuesday, we could see some spotty areas of light wintry mix. It’s also possible that most or all of the precipitation is suppressed to our south. Either way, it’s another mostly cloudy day as temperatures struggle to rise, with highs in the 30s to near 40. A few rain or snow showers are still possible Tuesday night as well, with lows falling back to the low 30s. Confidence: Low-Medium
Warmer weather returns Wednesday as high pressure sets up across the Southeast and sends light winds from the south-southwest our way. We should manage at least partly sunny skies with highs in the mid-50s to near 60. Confidence: Medium
