Not exactly there was a signal for Presidents’ Day off and on for weeks. At one point some models were showing 15-20” with temps in the lower 20s even if a blip south across Pa Md De and Nj
So ingredient #1 looks like a NW flow pretty evident with a low north of Quebec Canada drifting SSW.
#2 Vort NNE of Winnepeg getting forced SSE.
#3 low in north central New Mexico about to get the boot eastbound.
#4 blocking NW flow will force storm to cut eastbound to our south then wait for a northern stream phase near Norfolk Va.
You can clearly see the pieces on the water vapor map.
This will be interesting to see unfold.
Ummm yes it was 47f some areas 50f the day before the March 12-14th superstorm. Hell it was 43f when the first flakes fell at onset with winds gusting to 40 mph out of the NNE.
Highest winds are moving east slowly in time as the high pressure builds in from the northwest and the bombing coastal storm slowly pulls away in the Atlantic gradually lessening the pressure gradient west to east.
