I’m not trying to sound alarmist or hype this but looking at the latest ensembles and operational runs, this storm could rival the January 1922 “Knickerbocker Storm”, Washington’s heaviest snowfall in recorded history with 28″ in downtown! Check out the latest GFS Ensembles: *Notice the Bulls-eye right over the immediate Washington Area* — if this pans out — this storm may be our #1 or #2 worst Blizzard so far in recorded history.
Here is the latest GFS Operational: Those of you in southern Maryland, don’t let your guard down… if sleet doesn’t mix in for long (and it’s not forecast to do so), you could also easily see over 2 feet of snow!
If you smooth the lines in the GFS above you would get a more realistic look at how much snow could fall… generally this is looking like a widespread accumulation of 2 feet with some folks getting 3 feet. Again as I said there could be some totals (especially in the western suburbs of DC and eastern facing slopes of the blue ridge) possibly receiving over 36″!
Here’s the latest European:
