4:45 PM: Video Update

3:00 PM: Here’s what we are expecting snowfall-wise through Thursday.


1:45 PM: Seeing the northern extent of the snow get compacted southward as the banding increases across the Mid-Atlantic. This is all expected. This banding will pivot into New England this evening. Until then, snowfall roads will NOT be an issue in southern New England!

Updated simulated radar guidance through evening shows how snow struggle to get north of the MA Pike while snow ends from west to east.

12:15 PM Video Update:

11:30 AM: Snow bands becoming much more well defined this morning as the coastal low pressure takes over. Seeing reports of 2-4″ in New York City metro, with 4-10″ across portions of Pennsylvania.

Current HRRR guidance continues to bring bands of moderate to at times heavy snowfall across the Mid-Atlantic through the afternoon, then pivots banding into New England for the evening commute and beyond…

Snowfall map has not changed much this morning – still expecting 8-14″ from southeastern PA into southwestern CT, with heaviest amounts in persistent banding. I also raised amounts in central PA where snow is currently falling. I think 5-8″ should do it in southern New England, with locally 8-10″ in heaviest banding.
