Very Cold, Windy

The cold has arrived as true arctic air has moved into the region.  The cold is very impressive for this time of year.  It will feel more like the middle of January than late November today and will feel even worse with the winds. 

Temperatures as of 7am are in the lower to middle 20's with a few spots closer to the Poconos in the teens.  Strong cold advection will be in place today as a deep trough and strong polar vortex from Canada sweep through.  There will be some instability aloft, so there will be a chance, mainly north and west of city, of seeing some snow showers and/or flurries.

Varying skies today will more clouds to the north and less to the south.  But overall, we'll see a mix of clouds and sun for the most part.  Winds will be quite strong from the Northwest, averaging around 20 mph with gusts near 40 mph at times.  Temperatures will not climb much today and highs for most areas will stay below freezing, with upper 20's to perhaps 30 as the rule for most places.  The only spots that may see temperatures reach freezing will be in southern Delaware.  These highs will average around 20-25 degrees below average. The last time we didn't reach freezing in November was 11/28/1996 (high of 30). Today will feature a pretty similar "high" water mark.
