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).
Uncertainty still exists in the models regarding how close to the coast the storm system on Saturday tracks. Any shift west will have a significant impact on our forecast. The upper level piece of energy responsible for Saturday’s system reaches the coast during the next 12 hours and we should finally have a much better grasp on track tomorrow.
