The combination of system and lake effect is bringing heavy snow squalls through the Great Lakes and across the Northeast today.

With lakes waters so warm and ice free it’s like lighting the fuel for major snowfall to the lee of all the lakes, especially Erie and Ontario.

It was a chilly start to Tuesday ahead of today’s system snow.

Over a foot of snow is expected up in Maine.

Snow flakes may fly in the Big Cities of the I95 corridor this evening along with gusty NW winds and falling temperatures.

The system dropped 3 inches on Chicago.

A stunning day in Chicago under crystal clear but cold blue skies following fresh overnight snowfall.

A cold night follows in the wake of the system from Upper to Lower Midwest into Ohio Valley.

The previous system which exited eastern Canada yesterday and cut power to homes in Maine generated a 144 mph wind gust over Mines Madeleine, elev 3,757ft on the Gaspe Peninsula, Quebec!

Check out the rime ice coating this exposed weather station.

The system which brought the pesky evening snows through the Midwest last night and the Northeast today will be followed by another two clipper-like systems of which may spawn a coastal storm ahead of the next surge of arctic air to drop out of Canada this weekend. The GFS sees this as a colder spot than the previous.

GFS 2m temperatures for Sun/Mon AM are impressive over the Upper Midwest.

GFS snow through the next 5 days.

Talking Tropics In Mid Winter?

Check this out, there’s a system moving ENE over the eastern Atlantic that the NHC has in fact given a 5% chance f becoming sub-tropical!

SPECIAL TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
105 PM EST TUE JAN 12 2016

For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

1. Cloudiness and thunderstorms have become a little more concentrated
and organized near the center of a non-tropical low pressure system
centered about 1100 miles southwest of the Azores.  The low is
producing winds to near 60 mph over the southern and eastern
portions of its circulation.  Although environmental conditions are
only marginally conducive for development, this system could become
a subtropical or tropical storm within the next day or so.  The
cyclone is expected to move eastward to northeastward over the
eastern subtropical Atlantic over the next couple of days.
Regardless of subtropical or tropical cyclone formation, this system
is expected to produce hazardous marine conditions over portions of
the eastern Atlantic for the next few days.  For additional
information, see High Seas Forecasts issued by the National Weather
Service and Meteo France.  The next Special Tropical Weather Outlook
on this system will be issued by 2 PM EST Wednesday.
* Formation chance through 48 hours…medium…50 percent
* Formation chance through 5 days…medium…50 percent
