Potential Snow Accumulations for Thursday’s Light Snow Event


The latest high-resolution forecast models continue to suggest that the coastal storm that develops late on Thursday evening may rob some of the lift (energy) from the upper-level system that will be responsible for producing some light snow across the DC Metropolitan Area.

  • Most locations south and east of Washington should pick up between a trace and at most a light dusting with higher totals well north and west of the Beltway.


The image below (courtesy TropicalTidbits.com) shows the latest future-cast radar (snow in blue) from 4pm Thursday through 8am Friday. 

As you can see, most of the steadier snow remains well north and west of the city (subject to change with future runs).

Wednesday Update on Prospects for Light Snow Thursday Evening

Looking at this morning’s latest forecast model brings back memories of the dreaded “DC area split” where everything goes wrong and snow falls east and west of us with flurries and a dusting at best in the immediate DC Metro.

While this morning’s models are showing some light snow impacting the area between 7PM Thursday and 1AM Friday, I am concerned that the mountains will block some of the moisture and that the coastal storm that develops will rob some of the energy (lift) giving our area only a few hours of potential light snow and only resulting in a dusting at best for most locations.

  • Very short window of time of some light snow before coastal storm begins to strengthen and robs us of lift (upward motion in atmosphere to produce snow).
