Wintry 1/20 - 1/23 Winter Storm

GFS here shows 500mb mid-upper level vertical motion and moisture increasing late this afternoon into this evening. Will be an abrupt end to the snow on the backside and blue skies in the morning for early pictures

I was going to make a call map yesterday but the shifting in the models just made it too difficult to pinpoint totals (especially further west).
I am banking on their being more precip than models have been showing with decent ratios. Looking at the radar you can see it's much healthier than models are showing and that phasing energy is just too much in a prime spot for most east of the apps to not get a decent moisture fetch. Couple that with under modeled FGEN driven precip and it's just screaming for a bust on the high end of totals pretty far back west. These totals might be too low honestly. Other story is the ice. Especially in the Pee Dee region and along 95 I think we easily should get a quarter of an inch of ice on average for most places.
 
I'm expecting around 1-2.5 inches of snow for Columbia and 0.5-2 inches for Aiken/Augusta. Nothing major,but just enough snow to keep us satisfied until next winter or atleast we get a pattern that conductive for a big snowfall around here. Wish us luck to truly finally our snowless streak broken today.
 
Wakefield has upped totals slightly for their Winter Storm Warning for coastal counties along the Chesapeake Bay, and seem to be hinting at the fact that blizzard conditions may be possible without going so far as issuing a blizzard warning.

"Periods of moderate to heavy snow expected. Total snow accumulations of 2 to 5 inches. Winds gusting as high as 35 mph near the immediate coast."

Man 2 inches is massive for a place that hasn’t seen widespread 1 inch totals in nearly 8 years.
 
This is a classic pre snow storm look on radar View attachment 109197
It something seeing the radar beginning to fill in like that… even though it’s light stuff. The best upper dynamics are still well back to the west and won’t be here for a few hours still

Cloud cover associated with our jet appears to be more northward than guidance suggets. Check out the IR satellite that has high clouds in the southern tip of Ohio (sorry the outlining is terrible its just COD) compared to the RGEM which has that feature only only barely extending into kentucky. This may suggest that the placement of the jet (and associated divergence aloft) is either stronger or more north than modeled.
