* Freeze Warning tonight for most of metro area*
8:10 p.m. update: Precipitation has come to an end or is about to end for just about everyone in the metro area. The Winter Weather Advisory for Montgomery and Howard counties has expired. But a Freeze Warning remains in effect for the entire area from midnight until 9 a.m. Lows in the upper 20s to low 30s mean some wet spots might freeze up, so take it easy on the roads tonight into mid-morning.
6:00 p.m. update: While some light snow continues in some of the north, northeast and west suburbs of D.C., this storm is winding down and the winter storm warnings out to the west for Loudoun and Frederick counties have expired. The winter weather advisory for Howard and Montgomery county remains in effect until 8 p.m. With sun setting and freezing temperatures tonight, look out for slick spots especially in outlying north and west areas where more snow fell.
Programming note: We got a TON of great snow photos and video today. Thanks SO much. It’s going to take some time to go through them, but we’ll try to aggregate some of the best and post in the next couple days. We’ll also recap the historic and hazardous snow situation in the Northeast where more than 1 million people are without power.
Overview and forecast through tonight: A mix of rain, sleet and snow changed to mainly snow west of I-95, with light accumulations in western Fairfax and Montgomery counties increasing as you headed north and west. Along and east of I-95, a sloppy mix of rain, sleet and snow occurred with up to a coating in some spots. Snow and mixed precipitation is winding down this evening from southwest to northeast. Gradually skies will clear and temperatures tonight will get quite cold, ranging from the mid-20s in some the coldest suburbs to the low 30s downtown - ending the growing season across much of the region. Gusty winds from the north this evening should settle to about 10-15 mph.
Record snow: Reagan National, which has received at least a trace of snow today, has tied the daily record for snow on Oct 29. Dulles Airport, which has received at least 0.6”, set a new daily snow record - as it has never snowed on this date as long as records have been kept. Not local, but New York City has blown by its all-time October snowfall record of 0.8” with at least 1.3”.
Record cold: The highs today of 42 at Reagan National and BWI and 39 Dulles were all the coldest on record.

5:30 p.m. update: The heavy snow band has moved off and some locations, especially near and east of I-95 have changed to drizzle. But light to sometimes moderate snow continues to the northwest which may try to pivot back to the southeast and bring one more round of flakes through the region. This storm is slow to move off which is sometimes the case with strong nor’easters.
4:45 p.m. update: The “super snow band” is quickly moving southeast stretching from southern Fairfax county through the District and central Prince George’s county into northern Anne Arundel county. Behind this band, snowfall rates will diminish leaving light snow or drizzle (especially east of I-95.)
4:15 p.m. update: Call it a super band: A moderate to heavy area of snow has set up from Gainesville, Va. up to about Baltimore, covering the area near the Fairfax/Loudoun county line through eastern Montgomery and then into Howard county. This band will move east-southeast and may whiten the ground in areas currently just wet.
