At this point I''m putting less stock into globals and focusing on nowcasting, and short-range models.

That's a great thing actually you won't 850 blue line the 0 line to be past you, if you review the link I sent you will see the blue and red lines think of the red and blue lines as hot and cold.... that 0 blue line means when stuff starts falling would fall as frozen stuff and you always want that to be pushing away the red if looking for good snow conditions
Another thing to watch for is if the 3-5" totals for snow falling do verify, there will be power outage problems. This heavy wet snow will stick to pine trees like glue.

WSW for me
However, they are crashing back in Texas.How accurate are the 850s on the mesoanalysis page?
Nvm 925s are warm so I guess sleet?
Short term models are key at this point. Hrrr is better than the rap imho

Hrrr continues to get colder.

No rain if it fell right now. Sleet normally forms when 850mb or so is warm and 950mb is below freezing.

According to the 850mb map on SPC mesoscale website, the 0°C line is crashing eastward nearing ATL. Last update showed it back north and west from a Rome to Helen, GA line.

What about at the other levels? Seems theres always a pocket at 700mb or somewhere else that won't ever erode.

Both are colder while the globals are warmer. What gives? Warm bias? Cold bias? A setup that the models can get a handle of?

Well there have been reports of sleet in south and central Alabama today
Then that is good. Means the RAP is currently running too warm.

SC's 850mb temperatures look like a bad case of taco bell methane release. Baffles me how many events have that CSRA warm nose bubbling right up the Savannah River.
FYI, KCHS has dropped to 45° already...colder than KGSP AND KCAE.

Still too warm for East of ATL (Athens area). Hopefully this trend will continue!!!!
700mb 0C holding steady across South Central AL, .........For now

East of 85 is most likely going to just have to look for cold air locked in and for it to not be like this, where clouds are blocking the temps from diving even if it warms higher than it has.
Thus, a different event.

Couldn't you say the same for most of the models except the HRRR?

50-1 odds it takes one last significant leap NW. Can't give you scientific reasoning other than it seems to always occur day of.....just my opinion, hopefully some of you will get an early christmas gift!
Possibly. I haven't had a chance to look in depth at the newer runs.
