NYC Area Forecast: First winter storm threat of the season late week
Briefing: A winter storm threat will evolve late this week, with the potential for snow in the Mid Atlantic and Northeast. Some snow is possible in NYC, but accumulating snow is much more likely in the interior.
A unique and unusual synoptic weather pattern will evolve this week leading to the potential for the seasons first winter storm, especially in the Interior parts of the Northeast. Even in the immediate suburbs of NYC, a few inches of snow may accumulate on Thursday on the front end of the storm system.
The storm system begins to evolve from Tuesday into Wednesday, as a cutoff low moves from the Mississippi River Valley towards the Mid-Atlantic states. Meanwhile, a deep trough in Southeastern Canada will reinforce cold air over New England. Very low dew points will sink southward into New England as a result – and this cold antecedent airmass will be a key to the forecast on Thursday.
