Winter Storm Threat: Dec 28-29 (initial call)

Another quick-turnaround forecast as the next system looks to bring widespread 1-4″ totals to the Mid-Atlantic, with higher totals in the central Appalachians. Marginal boundary layer temperatures and initial surface winds out of the southeast makes finding that 1″ boundary a challenge yet again. Luckily, the upper-level temperatures are cooperating more this time around, so if your surface temperature is at or below freezing you’ll almost certainly be getting some accumulation. Mixing areas will mostly be rain/snow, but some sleet is still possible.

I’ll be traveling tomorrow, so if/when I update it will be in the evening. Verifications will come once these back-to-back events slow down!
