From GRR's pm disco (that I just read tbh). Anyone familiar with this model version they mentioned doing so well?

 

-- Accumulating snow into this evening --


We will continue our headlines as they are with no changes. The
jet dynamics forced snow event will be at it`s max snowfall rates
in the 5 pm till 7 pm time frame. Based on the HRRRdev3 12z run(the
only hi-res model to show the lead snow band as it actually was)
shows snowfall rates of 0.5 to 1.0 inches per hour from near
(just south of) I-96 from 5 pm till 7 pm and comes up with total
(using variable snow density) of 3 to 4 inches near I-96, 4 to 6
inches for our two northern rows of counties and 1 to 2 inches for
our southern 2 rows of counties. Given we had 1.5 inches from the
event at our office so far, this means we need only another 1.5
inches to reach the model forecast.

As far as weather goes, there is less snow now than this morning since a bit more melted today. I ended up with 0.07" of rain today with a bit of sleet mixed in at first. And on Friday I picked up only .5" of fluffy snow on top of the old snow. It's been boring lately but winter was active and much wetter than normal so far here.

Thinking it over a bit maybe this winter wasn't a lot wetter than normal except for January.

All the model runs that tried to dip the heavy band into Iowa were wrong.  The Canadian was way off.
