Blowing & Drifting Snow Headed for Washington!

A Winter Storm Watch has been issued by the National Weather Service for the entire Washington Region for the potential of 5 or more inches of snow accumulation on Tuesday.


Latest North American Model (NAM) Potential Snowfall Accumulations
Latest Snowfall Forecast from the North American Model (NAM) – 6 to 8″
Latest Snowfall Forecast from the GFS (Global Forecast System)
Latest Snowfall Forecast from the Global Forecast System (GFS) – 6 to 8″ with locally 10″

It will be a spectacular Martin Luther King Day across the National Capital Region as temperatures rise into the middle to upper 50s under mostly sunny skies! Don’t let the mild weather fool you, blowing and drifting snow will impact the Washington Area with treacherous travel tomorrow! 

An arctic front, upper level disturbance and developing coastal storm will all combine to produce snow… heavy at times across the entire National Capital Region on Tuesday. Snow will start out wet but will transition over to a dry snow as temperatures plummet into the teens.  

**The latest forecast models are in general agreement of 4 to 6″ falling with the potential for a sweet spot of 6 to 10 inches somewhere across our Area. Northeast winds of 20 mph with gusts to 35 mph will cause widespread blowing and drifting snow on Tuesday afternoon.  I expect widespread closings on Tuesday. Wind chills will be dropping into the single digits below zero during the day with near white out conditions at times! **

I will put out a snowfall accumulation map today as soon as I pin down where I believe the bull’s-eye may fall.  Stay Tuned.
