11:30 Monday Evening Update

Very impressive plume of moisture moving northward out of the Carolinas as colder air is becoming entrenched across the Metropolitan Area. High Resolution Models becoming very bullish on much heavier snowfall totals inching closer to the Capital Beltway.

This storm is now in “now-cast” mode… as ingredients are coming together for a high-impact dangerous Winter Storm across the immediate Washington & Baltimore Metropolitan Areas

** This may be one of our areas biggest March Snowfalls north and west of the Beltway**

DCstorms.com is now predicting a  70 to 80% chance of Federal Offices closing based upon the latest HRRR data. Temperatures in DC are now forecast to drop into the upper 20s!

Heavy Snow may hold on longer across DC before changing over to sleet and/or Freezing rain. Sleet accumulations may be pretty hefty with locations picking up one to two inches along and east of interstate 95!  As colder air wraps in, locations that go over to sleet and freezing rain will change back over to snow Tuesday morning. Scattered Snow Showers will continue throughout the day on Tuesday. 

Freezing rain is now a grave concern along/ south and east of interstate 95 creating absolutely treacherous travel. Stay off the roads tomorrow! 

Latest HRRR:  

  • Heavy Snow may hold on longer in DC (until 5AM) with higher snowfall totals inside the beltway than forecast earlier by the models.
  • Heavy freezing rain and sleet are also likely to hold on longer in the immediate Washington Area leading to absolutely treacherous travel (ice-covered roadways with sleet and snow underneath).

    It should be interesting to see what happens later tonight when the colder air aloft starts coming back into play. At least most places west of DC are currently just receiving light snow, not moderate or heavy snow. So it isn’t as if we are getting clobbered by those places at this point.

    “This may be one of our areas biggest March Snowfalls north and west of the Beltway.” What are you smoking? We ended up with less than 2″ in Chantilly.

      We have some more scattered snow showers as upper-level energy pivots overhead, but anything over a dusting is not anticipated. I was looking forward to a bit more as well. I’m just happy we finally got enough to not see the grass.
