Travel Nearly Impossible Thursday as High-Impact Winter Storm Blasts DC Area

Latest Snow and Sleet Accumulation Potential Map

This will be a high-impact winter storm with a crippling sleet and/or freezing rain event along and east of Interstate 95.  For those of you in the 6 to 10″ area of my map below — this is mainly a snow event .  Elsewhere, precipitation will begin as a period of accumulating snow before changing to sleet  and/or freezing rain.

The million dollar question remains whether we see mostly sleet (ice pellets) or freezing rain (liquid that falls and freezes on everything).

Ice Accumulations from Freezing Rain could be Crippling along Interstate 95

The latest SREF model (image below) continues to be very bullish on a damaging Ice Storm for locations along Interstate 95 northward to DC and eastward towards Annapolis. 

Prepare now for the potential loss of power where damage to trees and power lines is likely if the freezing rain does materialize.

Timing the Wintry Mess

The image below (courtesy Tropical Tidbits) from the North American Model (NAM) shows snow (blue), sleet (purple) and freezing rain (pink) impacting  our region between 3 AM Thursday and 6 AM Friday morning.

Travel will be nearly impossible across the Washington Region on Thursday with snow and ice covered roadways and temperatures holding below freezing.
