Bitter cold temperatures continued overnight east of the divide as
a strong Arctic high pressure system sat over the Northern Plains.
Temperatures last evening quickly dropped into the teens and 20s
below zero from the Hi-line into SE Montana. Areas of low clouds
and some fog were located along the south central foothills as
well as in the valleys of western Montana, otherwise skies stayed
mostly clear. At 3 am temperatures ranged from 25 degrees in Great
Falls to to -29 degrees in Havre, a 54 degree difference over
about 100 miles.

For today...the bitter cold air across the eastern plains will
begin to moderate today as westerly winds increase this afternoon.
Sunny skies will prevail, though low clouds will remain locked in
to some western valley locations. Temperatures will be mainly in
the 30s and 40s west of the divide into the foothills, with teens
and 20s farther east.
