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.

Radar beam tends to overshoot them at that distance from the radar. Snow squalls are usually lower topped.

Snow Squall Warnings for the Poconos and the Lehigh Valley currently.

Yup the massive upward motion in that band that interesected the DGZ coupled with deep saturation resulted in much higher SLRs.

It is completely different. This was via very strong/deep frontogenesis in combination with upper level jet dynamics.

Easily half of the 4 inches of snow here has already melted.

The consistency of the snow was wetter than I thought it would be. Looks beautiful though covering all the trees.

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!

I don’t think it is subsidence, but rather weaker lift outside of the strong lift that is producing the band.

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.

Quick look at radar and the HRRR and it looks like the HRRR is not initializing the heavy band of snow in OH and western PA quite right.

Nope, my shift is wrapping up shortly.

Well, some of you got your upgrade to a Winter Storm Warning.

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.

Impressive storm in more ways than one.
