We continue to monitor the upcoming onslaught of more winter and extreme weather. The type of cold on the way is more suited to mid winter with a 1040 arctic high set to drop out of Canada.

Temps will range between 20 and 40 below normal from Canada to the Gulf of Mexico by mid week while a potentially major coastal storm develops and bombs out off the New England coast.

The below ECMWF surface charts show how things come together. First, the arctic air dives south and becomes dominant, second we see a system forming over the Rockies which rides the base of the trough, third we have further upper energy streaming into the country from Alberta which eventually catches the system off it heads off the VA coast.
