Here are the Latest Snowfall Reports (a bust with mainly sleet in Metro DC) from the NWS Database
As has been the trend this winter, the far northwest suburbs received a bit more snow but sleet even ruined the party for these areas as well with 7.2″ so far being the unofficial winner near Martinsburg, WV.
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 National Weather Service will likely issue Winter Storm Watches today for the entire Washington Region for significant snow and ice depending upon your exact location Wednesday night through Friday morning.
I give this event a snow plow rating ofdisruptive as I expect snow-covered roadways on Thursday morning with temperatures in the middle to upper 20s.
Snow will begin to mix with and change over to Sleet and Freezing Rain before transitioning to an Ice Storm with Freezing Rain likely across much of the region, mainly east of the Blue Ridge mountains.
Ice amounts could be crippling with over a quarter-inch of ice accretion from Freezing Rain causing scattered to widespread power outages along and east of the Interstate 95 corridor and nearly impossible travel.
