Hey guys. Not sure if anyone remembers me, but I'm excited to see many of you cashing in on this really impressive overrunning snowfall event. The rain/snow line has been firmly holding around I-85, but I think as the last batch of significant precip moves through overnight and early this morning the 850-hPa 0C line which has been nearly stationary the last 6 hours or so will begin to shift south and those that have been shut out so far (i.e., south of I-85) will pick up some accumulating snowfall by daybreak when the event wraps up. 

I was actually in Greenville, SC just a few days ago, so I'm a little bummed I just missed how impressive this event has become for the southeast!

I do have a few HRRR maps going to should be updating hourly for you guys to watch the event (centered on Charlotte and Atlanta respectively). Let me know if you guys have any more requests!

Frontogenesis maps (useful to show where greatest forcing for precipitation along the frontal boundary)

Looks like the snow/sleet blob is finally moving out and in a temporary lull with light snow/sleet... I'm hoping the next batch will be all snow.. sounds like it hearing from folks upstream.

We've got 1-1.5" so far with a nice thin layer of sleet.
