Cold Air Invasion from Canada, with 20 to 30 below zero Fahrenheit temps to end December 2014. Air is coming over the northern Rockies from north-central Canada in a Northeast flow aloft. This is a very cold Trof of Low pressure in the upper levels of the atmosphere and strong High pressure at the surface in southern Canada & over Montana. No inversion today, but that changes and we do warm up at higher elevations Wednesday & Thursday. Valley stays colder.
