GREAT FALLS — We're tracking an arctic cold front moving through the state on Sunday. Behind the front temperatures have fallen into the single digits, even below zero.
Temperatures will continue to fall as the front pushes south. Overnight lows will range from the single digits near Helena to as cold as teens below zero near Cut Bank.
A Wind Chill Warning is in effect for Glacier, Toole, Liberty, and Pondera County through Monday morning. Wind chills in the warned area may fall as low as -50!
Frostbite can occur in as little as 5 minutes in temperatures that cold,
High temperatures will be near or below zero through Thursday for most of North Central Montana.
Helena will be quite a bit warmer, but still cold. Highs in the single digits to teens are expected in Helena through the next 4 days.
We're also tracking snow on top of the cold, with a few bands of snow expected to move through the state overnight.
Most of us will see between 1 and 3 inches of snow, with more at higher elevations.
On top of all of the winter weather, a Flood Watch remains in effect for the Missouri River near Great Falls. An ice jam there has kept water levels very high, and flooding remains a possibility.
