DC Regional View:

Preliminary DC Area Snowfall Accumulation Forecast for March 14th Blockbuster Nor’easter

  • Heaviest Snow should fall overnight Monday through Tuesday morning with snowfall rates of 1 to 2″ per hour; thunder-snow is possible, widespread snow showers likely Tuesday afternoon through Wednesday as upper level trough crosses the region (additional snowfall accumulation possible).


  • Winds will gust well over 45 mph Tuesday through Wednesday with scattered power outages likely especially in areas near 32 degrees (heavy, wet, snow).


  • Tricky forecast remains for the interstate 95 corridor as amounts may be much higher if mixing with sleet and or rain doesn’t occur.


  • Stay tuned for updates this afternoon & evening.
