Wintry Feb 6-8 2022 Winter Potential

These setups can indeed be very tricky, but welcome to the frickin' Southeast lol. If the moisture could roll in during early morning hours with heavy enough rates to crash the column, perhaps we could have predominately sleet. Then again, especially pertaining to the past few years, what I think I know versus what has occurred?? Someone will probably get half a foot of snow??(Disclosure: This is not a forecast.)

That’s been the story of my 41 years doing this dumb hobby

You too? I’m actually in charlotte to go to a hornets game tonight. We understand pain.

Models do look good though. Monday looks way more than my expectations were at, which were admittedly low.
 
I can't say how many times; she gone and ain't comin' back.... she leavin' you for a woman... You didn't cut her enough slack....
 
A fold is not when a models stops showing it for one run. There will be more runs to determine this
 
I feel Charlotte will get a hinch(aka 1/100th) of an inch. Patenting a new meteorological term. Sounds a hell of a lot better than little to no accumulation.
 
CMC is winter weather advisory for most of upstate SC and all the NC foothills and western Piedmont counties

RGEM continues to be off it's rocker and yet it was so good just a few weeks ago

12z cmc also has stayed consistent with onset ice along with the RGEM everyone says it’s good with CAD around here until it’s on an island .. we will see I guess

And of course the famous words... “Wintry mix north and west of the Triangle” are being echoed across the local weather reports. “North and west... North and west”.

Yep. Better chance of pingers toward the "climatologically favored areas of the NW piedmont."
 
DOT out throwing the salt down.

35/14 with NE breeze at high noon. Chilly day no doubt, despite full sun

Keep in mind the loop that @Ollie Williams posted yesterday (reposting below) that showed an obvious strong cold bias of the RGEM vs the NAM/GFS/WRF and what I then said about it:

“If this doesn’t show how cold biased the RGEM is, I don’t know what would. Don’t just focus on your area. Look at how much colder it is in VA, TN, etc. Also, Jackson, MS, for example, where it has 16 vs 30 for the other models. It has Birmingham at 23 vs low 30s on others. Washington, DC, at 12 vs 20s others.”

So, IF the RGEM is on an island being colder than the others, I’d strongly suspect it is because of its cold bias. There’d need to be other models to be about as cold for me to not want to throw it out.

This loop was for today at 7AM EST/6 AM CST. I will shortly see what Jackson, Birmingham, and DC were actually at to see how these models did:

Edit:
1. Washington, DC/Baltimore area (Dulles/Andrews AFB/BWI) at 7 AM was actually 18-21. RGEM had 12 and others had 23-25. So, RGEM was ~7 F too cold but others were ~5 F too warm.

2. Birmingham/Shelby County airport at 6AM CST were actually 30-32 though the earlier lows were colder at 26-30. RGEM had 23 vs low 30s on others at 6AM. So, RGEM was at 6AM ~8 F too cold while others were almost perfect.

3. Jackson, MS, at 6 AM CST was actually 23-25 (with earlier lows at 21-24). At 6AM CST, RGEM had 16-17 vs 30-34 on others. So, RGEM was ~7 F too cold but others were ~8 F too warm.

HRR and RAP both have wet bulbs in the triad in the 28-30 range from 6-10 am in the morning. Seems it’s just a matter of how quickly the precip moves in. I’m putting my money on a wwa for the triad tomorrow morning from 6am to noon. I suspect there to be school disruptions.

GSP updated ice forecast. Throws some glazing along north CLT and 85 N and E.

RAH's map hasn't been updated since early AM (shows no amounts yet).

I think that’s too bullish IMO. It’s likely going to follow climo which would mean that it would likely setup like this, with less in the mountains.

Wet bulb temperatures on soundings all along the shaded areas on my map when precip is moving in is at and below 32, it’s not really bullish having a small T-0.05 And considering areas tonight further north have radiational cooling including the triad before clouds move in, also there’s a stout dry layer in the foothills and mountains limiting precipitation further west. 57BB2F4C-56B3-45DD-9471-96A09D7F906B.png my map even goes with GSPs thought
 
I think temps will be above freezing before anything meaningful hits the ground this is all driven by lift too so we're saturating the column from the top down.

Maybe I'm just a little salty, but I can't think of a time when I've been following models where ZR accumulation was more than expected; it always verified to the NW fringing me. I could be wrong, but that's my opinion from personal experience.

Im in the heart of cad even if the qpf was more on the models I still wouldn't worry these things hardly ever materialize in this type setup this thing died a long time ago ensembles never supported it.Theres just no support among the models except maybe rgem maybe elevated surfaces see a very very light glaze u have to rub ur fingers on to feel.

Out ur way and to the NE along 85 is the best location to see a glaze I think ur map is spot on.
