November 20-21 Early Season Snowstorm Part 2

Recommended Posts

Good to see the snow wins the melting battle....

Such a steep drop off wrt accumulations from Detroit to Windsor.... Hope the SW trend holds another 10 miles.

Snow pretty much stuck on grass from the start. Roads were wet until the heavy stuff started, and then things deteriorated quickly. Good thing there is little wind or the northern part of Iowa would be shut down.

Question: what's causing the early onset of snow in Chicago metro? Quicker movement? Or more rapid saturation than anticipated which may help totals?

Probably a little bit of both, based on radar trends.

Where the placement of the surface low is forecasted to be, the rap may be too bullish with its tick Southward of the heavy snow band. Maybe it's overestimating dynamic cooling some? Going with a total of 2.4 inches of slop here just ese of Peoria I think.

This early fgen band was well modeled ahead of the main show

I may double that here on the north side of PIA (4-5)

 

but just north around chillicothe  may be 6-8

 

The cut off is going to be sharp

Surprised to see IND isn't more bullish.  Just checked the forecast for LAF and it's only up to an inch.  Definitely some bust potential there.

I do think things got saturated pretty quickly though, there was a bit of expectation that you'd burn a couple hours moistening the column but that doesn't seem to be the case. Speaking of which, I see the moon is gone, so we are starting to moisten the column here as well as the clouds thicken and lower.

Thanks. LOT noted it would weaken considerably from its strength in Iowa. Also, figured the band would take time to saturate and would be mixed with rain. Positive signs if your a snow lover in the early stages.

That area of 12"+ totals in SE. SD/NW. IA has now extended east into N-C. IA near I-35 (Clarion/Hampton area).

 

Given reports further east, it looks like this axis of 12"+ totals will soon extend east towards the Waterloo/Waverly area.

 

Will be interesting to see if that axis continues east towards DBQ/FEP and beyond.
