Arctic air filters into Great Lakes with continued heavy snowfall

Quick late-evening update for subscribers.

Wednesday Headlines:

1. Arctic blast battled back by southerly (much warmer) flow out of Texas. However, bitterly cold temperatures up to 30°F below normal in the Midwest bleed eastward into the Great Lakes and Northeast with some moderation into Friday.

   Notably chilly day in Florida on Thursday.

   

   The extreme cold over the warmer Great Lakes = huge Lake Effect snow continues across Michigan, PA, and New York including Buffalo.

   A series of storm systems move into the West Coast yielding substantial rain across Northern California, and plenty of mountain snowfall.

   

   

   Bomb Cyclone to Bomb Anticyclone

   

   The strong storm moving through New England tracks up into Quebec and deepens enough to be classified as a “bomb” or rapid intensifying extratropical cyclone.

   Then, by late Saturday rapid pressure rises up to 1048 mb over Northeast. Whoa!

   

   48-Hour Snowfall from NWS

   

   LAKE EFFECT (!) measured in feet.

   

   California rain and snow next 72-hours
