My Snow Call:
Anderson, SC to Raleigh: up to 1” of snow/sleet. 1/4” ice or less. Change to plain rain
Clemson-Greenville-Charlotte-Greensboro: 1-4” of snow/sleet. 1/4-1/2” ice (maybe a small finger of higher totals). Eastern areas may change to rain but may also switch to light backside snow
Clayton, Ga-statesvill/hickory-Winston Salem: this is the biggest battleground with snow and sleet. Also biggest range of possible accumulation. I’m going 4-8” with the potential for less due to sleet compaction. Sensibly I think the lower end of that range is more likely but if that front end is truly a thump I think 8” is possible
Foothills including Asheville: 6-10” with some sleet mixing
Mountains: 10-16” highest on peaks. There could be some mixing issues even here but I think cold air and heavy rates with high ratios at the beginning and end will allow this to be a major snow storm regardless
My forecast confidence: High- we’ve seen these storms a billion times
Where it could go wrong: foothills to I-85 is my biggest question mark. I really think with the screaming 850 jet out of the east the mixing will occur faster than modeled, so it’s a matter of how much snow comes before the mix. In the Raleigh to Anderson areas, how long does the sub freezing air hang on, and can we approach warning level ice? In the ice storm areas, where does the narrow ribbon of extreme ice (over 1/2”) setup exactly?
Not a “fun storm” but been fun tracking. Good luck to those in the snow areas and hopefully power stays on for everyone
