A disturbance is expected to swing into the D.C. area late Thursday into Friday morning bringing a chance for light snow and colder temperatures.
After looking at some of the latest guidance, the east coast still looks like it will see the chance for some light snow, though little is expected for the D.C. area. At this time, Thursday looks cloudy and cool with temperatures in the low 40s.
Precipitation is expected to move in from the west and southwest as a disturbance (which will move into the Pacific Northwest today) digs into the Tennessee Valley and pulls some Gulf and Atlantic moisture over the Mid Atlantic.

Precipitation appears like it will fall mainly in the form of snow, though accumulations still appear light. The latest guess would be anywhere from a few flurries to the potential of an inch or two.
The main low develops so far out in the Atlantic and progresses east quickly which gives little time for snow to fall in the D.C. area. Typically the bigger snowstorms will feature low pressure tracking in a more north-northeasterly course, which would pull in more moisture from the Atlantic into the D.C. area. This just doesn't seem to be the case with this system.
Regardless, with the potential for snow late Thursday into early Friday morning, there will be the possibility of delays come Friday morning. Again, we'll be sure to update you over the possibilities again tomorrow and Thursday, no need to fret just yet!

Gusty winds and cold temperatures may be a bigger story on Friday, with winds up to 30 mph or higher at times and temperatures only in the 20s throughout the day on Friday.
Friday night into Saturday looks like it may be the coldest night of the season, with lows in the teens throughout the D.C. area and the possibility of a few locations in the far northwestern suburbs dipping into the single digits.
High pressure appears like it will regain hold of the region Saturday before the next area of low pressure moves into the region Sunday into Monday.
This system may also bear watching but is far enough out that we're not putting too much stock in it just yet. Another strong cold push is possible next week behind that disturbance.
