WEATHER BLOG: Snow Again?

Patchy clouds will fill the skies Sunday.

A weak zone of high pressure will stretch from eastern Canada into the Northeast will bring mainly clear
skies on Monday night into early Tuesday.

The focus of attention will then shift to a significant storm that will impact the Md-Atlantic states later on Tuesday into Wednesday. On Monday the storm will bring snow to the upper Midwest and on Tuesday the snow will shift into the southern Great Lakes and central Appalachians late in the day. The approaching storm will bring thickening clouds on Tuesday and some light rain late in the day. A rain and snow mix will continue at night and likely change to just snow around daybreak on Wednesday.

As the storm reaches the East Coast on Wednesday, it will cause a new low center to form and rapidly
intensify near the Virginia Capes. The vast majority of solutions suggest that this explosive low will bring a 12-24 hour period of heavy snow and wind to areas from far southern New Jersey to eastern Maryland, Delaware and parts of northern Virginia from on Wednesday and Wednesday night. Onshore winds would cause a brief period of rain at the coast in these areas.

Significant accumulations are likely with a 50/50 shot of a double digit snowfall in and around the city.
Meanwhile, winds will likely exceed 30 mph for a time and could gust to over 40 mph, which will create the
potential for significant drifting. This is a volatile situation that we will closely monitor over the next couple of days.
