Coastal Flood Warning through noon Friday for D.C., Fairfax-Arlington, Falls Church and Alexandria along the Potomac.

9:05 p.m. update: A Flash Flood Warning has been issued for central Fairfax County until 11 p.m., including the areas of Chantilly, Great Falls, Reston and Wolf Trap. More heavy rain is moving north through the warned area and flash flooding has already been reported. Never try to cross a flooded road. And be extra cautious at night when it’s hard to see water covering the road.

7:15 p.m. update: The first batch (and probably the worst of the night) is headed north and northeast of the area after dropping over 1 inch of rain in spots mainly west and north of 95. Additional storms have developed to the southwest of the area and they may rotate through during the late evening. However, the tornado threat should continue to wane and the main risk will be additional rain and perhaps some high winds. Several tornado reports have come in to the south of the area. Keep tabs on additional severe reports as they trickle in here.

Through Tonight: Occasional showers and thunderstorms are likely, particularly this evening. We’ll need to watch for isolated severe weather early too, including an isolated tornado. This will be mixed with potentially more persistent areas of drizzle. It should not be raining hard most of the time though. Lows reach the upper 50s to lower 60s. With light winds and dew points near the temperature, some spotty fog is possible.

Tomorrow (Friday): It’s mostly cloudy again, but fear not -- the sun is coming back for the weekend! Showers are also a good bet once more as a cold front pushes through the area. The main impact of this front will be to rid us of the cloudy and wet conditions, though winds should also pick up a good bit from the northwest late. Before that, highs should range from near 70 and into the low 70s.

September rains: The National Weather Service office in State College, Pa. announced today that September was the wettest on record for the state. This might not be a shock to those who were in and around the region during the month. However, in most cases when we got hit, Pa. got hit harder. On the positive side, drought watches in northwest portions of the state have now been lifted!

Pollen update: The last 24 hour report has been washed out due to recent rain.

6:40 p.m. update: Heavy rain is the main story as of this time, with storms running into more stable air the tornado threat is waning. A photo on Twitter from earlier (in what seems to be Fairfax) appears to show a wall cloud or funnel cloud which is often associated with a tornado. We don’t have any confirmation of one ever being on the ground yet though. See previous storm updates...

6:05 p.m. update: There are no active warnings at the moment as storms generally run into more stable (less threatening) air from D.C. and to the north. We’ll still need to watch for the potential of additional tornado warnings for a bit though. We’ve also received multiple damage reports from Fauquier County to the east of Warrenton.

5:35 p.m. update: There are now two separate TORNADO WARNINGS for the immediate area. One storm is impacting Stafford and Prince William with another over Fairfax County. Both warnings run until 6:00 p.m.

5:10 p.m. update: TORNADO WARNING for City of Manassas, eastern Fauquier and western Prince William counties until 5:30 p.m. Manassas and Bull Run are in the path of this storm. Get to an interior room on lowest floor of sturdy building.

4:55 p.m. update: Generally speaking, we have an area of strong storms approaching quickly from the south, currently focused along and west of I-95 and south of I-66 in Fauquier, Stafford and Prince William counties. These storms are headed north for Fairfax, Loudoun and Montgomery counties in the next hour.

Watch overview: A Tornado Watch has been issued for most of the metro area, except Frederick and Howard counties and points north. The watch goes until 9 p.m. From the National Weather Service: “TORNADOES ... HAIL TO 1 INCH IN DIAMETER ... THUNDERSTORM WIND GUSTS TO 70 MPH ... AND DANGEROUS LIGHTNING ARE POSSIBLE.” A Tornado Warning was in effect until 5 p.m. well to the southwest of D.C. in southwest Fauquier into eastern Culpeper counties.

3:30 p.m.: After some morning rumbles, it’s been mainly tranquil since the midday outside a few showers dotting the area along with some drizzle. For the most part, that remains the story, though we may see a wave or two of more widespread showers or storms this evening into overnight. There has been a pretty wide spread in temperatures from the upper 60s to the west to the mid-70s to the east, and even a few spots of sun here and there. Keep those umbrellas handy, just in case!
