Winter Weather Advisory up for D.C. & vicinity


TUESDAY EVENING UPDATE: The winter weather advisory is now for 1-2" of snow and some ice through 1 a.m. Wednesday morning, rather than 2-4" of snow.

From Monday evening: The D.C. snow hole is finally filled. Well, at least it is in terms of being under a Winter Weather Advisory. Earlier, we showed you the National Weather Service map of watches, warnings and advisories for a full one-third of the U.S. population, according to The Weather Channel.

But as we said in that post, it would likely just be a matter of time until a Winter Weather Advisory was issued for the metro area. Indeed, the entire region is now under a Winter Weather Advisory effective 4 p.m. Tuesday to 6 a.m. Wednesday. From NWS:

* ACCUMULATIONS...2 TO 4 INCHES.

* TIMING...SNOW WILL BEGIN DURING THE LATE AFTERNOON ON TUESDAY...AND CONTINUE THROUGH TUESDAY NIGHT. THE SNOW WILL BE HEAVIEST BETWEEN 7 PM TUESDAY AND 1 AM WEDNESDAY.

The above forecast is fairly consistent with our accumulation map and timeline from earlier, though that map has much of the metro area in the 1-3" range, with 2-4" from just northeast of D.C. and heading to the northeast (pretty minor difference).

We're in the process of reviewing this evening's model data, which is still coming in, and will let you know if we have any changes to our forecast with our next update, by around 11 p.m.
