Hrrr has been spot on for here this winter so im believing it. To be fair it showed me at 34 the lowest temp..think i misread it earlier.  Dropped to 35 briefly now back to 36/15.

If its right Mack may see some pingers and a sliver up through NC..thats about it

Maybe just my pessimism but I'm calling no go for MBY in Easley. Have made it down to 32 but hasn't budged in awhile and no stars above. Temp will only go up as clouds thicken.

Sounds like everyone is cooling off as expected and everything appears to be on track for a wintry mess in the CAD regions.

Having a tough time dropping the temp here with a southerly wind and cloud cover. Been at 36 degrees for a few hours. However, the dew point depression is still large enough for quite a bit of evaporational cooling to take place once the precip moves in.

I will say looking at your current conditions, your DP is 19. May allow you to drop a couple more degrees yet.

Ummmmm.... I highly recommend you upstate people go to FB and find the WYFF - Chris Justice update from about an hour ago!!! That future cast radar looks like it could get RGEM totals!! There is some mod/heavy rain falling and it's frozen according to radar!! I know, self limiting, latent heat release, blah blah, but moderate Precip, could aid in a lot better wet-bulbing conditions! You get that precip at 29/30 degrees, which is not at all impossible, and your gonna have big problems!! Ask Lookout about temps being forecasted about 3-5 degrees too high! And tree loss! ( yes that was a different set up) but just making a point

Yeah the average error rate is generally in that neighborhood in cad situations if the setup is right. I haven't had much time to look at things but based on the nam having the cold pool up to and above 950mb north of 85...along with NE to ene flow through that level..it's a bit worrisome. It means we likely will see good temp response via evap cooling..and the cold pool won't be scoured out or warmed up through WAA alone.  Negative factor is the precip rates...looks  heavy enough that drag could help temps rise...plus it's hard to accumulative fast raining that hard. 

That said, its pretty much a lock the models are at least a few degrees too warm after saturation...especially given the depth being up to 950mb.. . Will be interesting to see if the high precip rates will keep ice totals in check. 

Had to be up here in gainesville...currently overcast and 35 over 14 with a 10mph or so ne wind.  Expecting to get to 29 here.

GSP says no, that won't be necessary! They've got it under control and won't need and ice storm warning or WSW. Their forecast is right on! What their update said

For sure but got to watch especially for me and the hickory area its very close..
