Front-end load of snow your way and now COLD weather. Yup. I got 2 1/2 out of December and looking for more. But yes, I did not think we would roll the cold like we have over the last few days.

burrel2 Posted January 3, 2018 Share Posted January 3, 2018 I actually like the look of the Monday storm. With the dampening shortwave I could easily see the surface low jumping from central Alabama to the Georgia coast, thus strengthening,(or as a result of), the insitu-wedge...

This will be an Arctic cold airnass, albeit stale, but with DPs in single digits and temps around 30, if we time it right, could be really bad!

jshetley Posted January 3, 2018 Share Posted January 3, 2018 The Euro shows ice too for the upstate and northeast GA with temps in the upper 20's over the GSP metro. Link to comment Share on other sites More sharing options...
BullCityWx Posted January 3, 2018 Share Posted January 3, 2018 Euro is warmer but honestly, given the event as modeled, I’d run with the Canadian. Link to comment Share on other sites More sharing options...

This is a pretty good setup for it to over perform and hang on a while.. Despite the cold source being cutoff and latent heat release, looking at gfs soundings the cold pool would be deep enough and cold enough to result in a prolonged period of subfreezing temps....long enough for some likely good accumulations. The good news is that this one likely won't get squashed by the pattern unlike the last few systems/potential systems. It seems the biggest chance of a bust would be if it is slower/further north and comes in later monday to give temps time to moderate. But this mornings runs are a bit quicker and further south...and overall there is very good agreement. temps/dewpoints/wetbulbs are more than cold enough. new 12z euro is absurd with it's dewpoints.....0 to -5F over ga 0z monday and -5 to -15 over the carolinas. euro starts everyone off in the 20s prior to precip arrival. euro is dropping 0.6 over nc to nearly an inch over north ga.

Iceagewhereartthou Posted January 3, 2018 Share Posted January 3, 2018 GSP not too impressed at this point. Says nuisance event for Monday morning before becoming all rain by midday when bulk of precip arrives. Needs to come in a day earlier when it's still cold, but of course it won't. I guess I have to move the CHS now to see snow... The current forecast has highs still only in the 30s with temps allowed to drop into the 20s Sunday evening. Looking at the partial thickness p-type nomograms for the three medium range models, there is decent agreement on any precip developing overnight being a mixed bag of snow, sleet and freezing rain across anywhere it reaches the ground in the CWFA. With PoPs ramping up overnight, I expect at least a nuisance ice/light snow event. At this point, it looks like WAA should gradually transition p-types to all rain by midday Monday (at the time of heaviest precip rates). With that said, using consensus temps and timing of PoPs, I do get some likely wintry p-type with light accums before daybreak Monday. This is especially a concern for the mountains. I will plan to add a mention of winter weather possible for Monday in the HWO. Link to comment Share on other sites More sharing options...
wncsnow Posted January 3, 2018 Share Posted January 3, 2018 EURO shows pretty nasty icing, especially NWNC and VA.. More than nuisance level for sure and its trending better.. We will see... The bomb heading up the East coast could help act as a 50/50 low and keep our cold air entrenched longer.. Probably why models are showing further south solutions Link to comment Share on other sites More sharing options...
JoshM Posted January 3, 2018 Share Posted January 3, 2018 If I were GSP, I wouldn't dare say anything about a big ice storm atm. With the way models have handled events this year, I'd be scared to say anything until 48 hours out at the most. Link to comment Share on other sites More sharing options...
mackerel_sky Posted January 3, 2018 Share Posted January 3, 2018 ^^^^^ Trust me, that's really bold for them, and they left room to escalate the event! But I don't know how many times I've heard " temps will warm above freezing by noon" and they never do. And if it trends 6-12 hours ahead of current predicted time, would be a bad situation!

Buddy1987 Posted January 3, 2018 Share Posted January 3, 2018 Guys, I haven't even remotely followed this event yet. Been so entertained by my family in Charleston and Ladson/Summerville area getting plastered. What does qpf look like for the general region?
