Upper Level Low Will Bring… Heavy Wet Snow


  • Light snow mixed with rain and sleet develops predawn Wednesday transitioning to all snow by mid to late afternoon.
  • Heavy, wet, snow will continue past the evening rush hour. Untreated roadways will quickly become snow covered and sloppy as snowfall rates of 1″ per hour are possible in heavy snow bands.



  • Back-breaking wet snow of 4 to 6 inches with isolated sweet spots of 7 to 9″ underneath the heavier banding of snow (this area is yet to be determined).
  • I will issue an updated snowfall accumulation map this afternoon.

  1. That they are! My what a difference 6 hours can make!!! My skepticism is waning, but (especially here near in the district) I am concerned the temps will be too marginal, (even with a significant snowfall rate and evaporative cooling) to accumulate much. OK, Put me in the 2-4 camp, but I do hope I am wrong!

  2. Great job calling this one long before anyone else had the courage to do so! I appreciated the early warning to get my “ducks in a row” today!

  3. looks like you have the rain/snow line a little too far S&W of DC for my tastes. IMO, this looks more like the 1-3 inch type storm for DC & its burbs.
