7″ or 14″ in Downtown Washington?

I’m sticking with my snowfall map from yesterday with 6 to 12″ along the interstate 95 corridor and upwards of 18″ in the higher elevations of the Shenandoah  Valley as well as the foothills of the Blue Ridge.  In the Immediate Washington Area, suburban Loudoun County will come in with the highest totals averaging 14″.  This will be a back-breaking, heavy, wet snow causing power outages and treacherous travel as conditions will rapidly deteriorate on Wednesday morning.

To make matters worse, the models are all over the place with how far east the 12 to 18″ of accumulations make it.  Take a look at the following:

Wednesday will certainly feature one heck of a storm with rapidly changing conditions and historic snowfall totals for March standards.
