I gotta ask because I am curious. Why do these maps show snow in the Midlands of SC when there is no way it will? Thanks!

Wintry Dec 8-10th Winter Storm
- Thread starter SimeonNC
- Start date
I did a quick google search to see if I could find a start time for the 00z/12z runs, but I didn't find anything specific to what time it starts.

It's likely sleet or freezing rain.

WRF models usually just come out all at once at like a certain time ... probably around the time Euro rolls out
Nicely done. Dark Knight is hands down my fav mod

Thank you.
It's probably not reaching the ground, but there's some light rain/snow returns developing across SW NC (near and SW of Asheville), extreme Northern SC, and TN right now.

Realistically how much of the precip in eastern Georgia like Athens for instance is actually snow ?

Snow? Little to none probably. Mostly sleet or ice.

So is the surprise you were talking about for N GA sleet and zr ?

Yes, could be more than expected.

.NEAR TERM /THROUGH SATURDAY/...
As of 900 PM EST Friday: As noted earlier, it`s taking a bit
longer for the column to saturate, so reduced pops again through the
late evening and early overnight, but increased pops in the morning
as even with light precip, the actual pops will be high. Just for
quality control, did re-run snow/ice accums, but changes are very
minimal. With this update, however, opted to issue a Winter Storm
Watch for the southern tier of counties. Confidence certainly not
high enough to go warning or advisory, and because they`ll be warmer
it looks like onset time will be later anyway, so didn`t start the
watch till 06z Sun. 18z guidance is once again trending colder at
the surface...FV3 is crazy with snowfall totals and NAM is just nuts
with ice. Certainly seems that *something* could happen in those
southern counties, even if the watch "only" transitions to an
advisory (and for the record, going from a watch to an advisory IS
an upgrade, because it`s a measure of confidence...for the policy
geeks out there the VTEC even has .UPG in it). Also, it`s possible
that accums in the area already in warnings may need to be bumped
up, but feel it more prudent to let the midnight shift take a look
at 00z models before going out with the final pre-storm forecast

Upper level trough putting out some pretty heavy snows in western Texas right now.

Sucks for the Dallas area that the upper level trough transfers it's energy to a newly developed upper level energy near AK/TN or I think Brent and other folks in Dallas could have seen snow.

Low is faster for arrival on the 00z Euro, 850s colder. Would imagine a better run is coming. It really doesnt matter at this point though, short range and nowcasting time.
Is it me or is this storm approaching faster than forecasted ? I don't see how this would start tommorow at midnight even with Virga
My cousin said there's light sleet making it down in kannapolis nc, interesting radar returns developing in the piedmont
I doubt it, the air is stable over the CAD regions.
