Weather Forecast: Warm before the storm
High pressure will bring warmer and dry conditions to the region today with highs 35 to 45. Lows drop to 15 to 25 degrees. Saturday will be partly cloudy with highs 25 to 35.
Colder air will drop south for the weekend with high temperatures falling below seasonal levels Sunday through early next week.
A white Christmas may be on tap for many areas across southeast Montana. Arctic air will bring temperatures falling into the teens on Monday, with temperatures topping out in the single digits and low teens on Christmas Day. This surge of arctic air will also bring the potential for accumulating snowfall from Sunday through Christmas morning.
The best chance of accumulating snowfall across the high plains will be on Christmas Eve and early Christmas Day. Most locations will see 1 to 3 inches, with higher amounts in the foothills and mountains. Snow-packed roads and cold temperatures will make holiday travel hazardous. Have an emergency kit in your vehicle to survive cold temperatures should you become stranded.
