Happy Sunday afternoon/evening to everyone. So far, we see nothing in the latest model guidance and radar trends to alter the forecast we've been sticking with since last night: 4-8" of snow for the immediate metro area, with less to the west/northwest and more to the east/southeast.

We're expecting the snow to develop from south to north between 3:30 and 5 p.m. (may start as a period of rain or rain/snow mix, especially from D.C. toward points south and east), with heavy snow and accumulations possible by early evening, when travel conditions could deteriorate rapidly. Heavy snow is already falling in parts of central Virginia and southward, with reports of thundersnow near Atlanta.

Putting this storm in perspective, this doesn't look like a storm of historic proportions for the immediate metro area -- but it is a major storm and the most snow we've seen in quite a while. Travel difficulties and cancellations are likely this evening through tomorrow. For those who love snow, enjoy! For those who don't, at least be happy that ice shouldn't be a factor.
