Very nice map. Very impressive.

Looks nice for me. Area G. NWS doesnt think so yet. Still only predicting 1-3.

totals in area G are going to be extremely variant. You may have an 8" total along the border w/ area D but perhaps as low as an inch near area H.

For the layman, what is a CSI band? I'm staining my little pea brain and I'm thinking it's probably NOT Crime Scene Investigation. :oops:

It's complicated, but the gist involves instability that may induce very heavy precipitation rates in localized areas, often see 2-3" of snow per hour in these narrow bands with occasional cloud-to-cloud lightning and thunder.

The Pittsburgh NWS just updated my forecast. They've lowered the temps a little and kept snow in the forecast for the next few days and lowered the chance of rain. Still keeping snow totals 1" to 3". Earlier there was more rain in the forecast.

Thanks for the explanation Purdue!

Temperature dropped about 5 degrees in last hour and it's near freezing here. Precip has lightened up and it looks to be a mix now...moderate snow not too far away. Paducah NWS office mentioned reports of thundersnow in southeast MO a couple of hours ago - evidence of very dynamic frontogenesis and instability feeding into the cold sector. This storm will most definitely come in two pieces now, the first ending by mid to late afternoon with the 2nd round beginning by evening and lasting into the night. The 2nd round will be more efficient at producing heavy snow since the column from the surface up will be much colder.

As far as models go, 6Z Eta sfc low somewhat weaker than 00Z run, and hence is slightly further east. Snow totals and locales mostly unaffected by this, however. High-res RUC model maintains snow to along and just south of Ohio River through 18Z tomorrow.

You're welcome! Enjoy that potential CSI (the snow or show)! :lol:
