The above image is what I think may fall across the National Capital Region by Sunday morning.  My map was made using a blend of the latest Euro, GFS and Canadian models (images below courtesy Weatherbell). I’m hopeful that my snowfall accumulation map will not need to be changed based on the trends that have held steady thus far.

Here’s the latest Euro, GFS and Canadian for you to make up your own minds:

Blizzard Watches have been issued for the Metro Area because of the threat of sustained winds and gusts that may lead to white-out conditions.

Some sleet may mix in with the snow on Friday evening in locations east of interstate 95 (likely the northern neck of VA, and southern Maryland).  But any mixing will change back over to snow as the Nor’easter pulls colder air into its center as it slowly wobbles to the east on Saturday morning. Locations that receive any mixing of sleet will still be receiving a crippling storm. In fact this storm should pretty much paralyze the entire region.

Some of the fun details that we could be enjoying on Friday night and Saturday is the possibility for some banding that develops. Some of the bands could put down some lightning… you can’t rule out some thunder-snow when systems deepen pretty rapidly.

The eastern slopes of the Blue ridge and foothills will have the opportunity in some of these snow bands to approach snowfall totals possibly over 36″. I would not be surprised to see some people reporting 38 to 44″ in the eastern facing higher elevations of the Blue Ridge mountains.
