Montana Weather Summary
National Weather Service Great Falls MT
500 PM MST Tue Jan 17 2017

Mild westerly flow aloft from the Pacific brought warmer conditions
to the Treasure State today with strongest warming occurring over
the Plains. High pressure over the Great Basin and Low pressure east
of the Rockies brought gusty west to southwest winds to much of
Central and Eastern Montana through this afternoon with the strongest
winds occurring along the East slopes of the Rockies.

Afternoon temperatures ranged from the teens in some of the valleys
of southwest and western Montana, where cold air was trapped below a
temperature inversion, to the mid 40s in some locations along the
east slopes of the Rockies. Readings at 4 PM ranged from 13 at
Helena to 44 at Cut Bank.

Cloud cover will increase across the region late tonight with
precipitation associated with an incoming Pacific storm system
reaching areas along the Idaho border by Wednesday morning.  Gusty
west to southwest winds will limit temperatures from falling much
tonight along the east slopes of the Rockies with near average low
temperatures elsewhere.
