The 700 mb FGEN was insane with this event, thus the crazy hourly snowfall rates and totals in a narrow band. This is from the SPC mesoscale analysis data.
4 inches at my place.
Wow regarding that intense band that occurred. The look of it on radar looked like a fire hose of snow that Buffalo gets off Lake Erie. Insane!
That is a result of tightening 700 mb frontogentic forcing. This is sloped ascent and this narrow band is on the north side of the 700 mb frontogensis. That translates eastward, but let’s see if it remains so narrow like that.
A little late for any winter storm watches to be issued. Advisories have already been issued, and some of those can always be upgraded to a warning if need be.
This is insane! I would literally be pulling my hair out if working today. Did mention over the weekend at work that this storm could be a surprise but was not sure where.
