I can't post because I'm mobile, but you can really see the low level jet starting to crank on the 925/850 mb SPC meso analysis. Should see the radar continue to light up.
Per the SPC mesoanalysis, the 925 low has closed off over the SC/NC border. This should help lock in low level sub freezing air for places that are already below freezing.
When I went to put the recycling out, I measured 3.8" It's actually a nice moderate snowfall now, but I'm not sure how long this is going to last. If it were to persist through even midnight I'd definitely clear 6".
