Frost and Freeze Probabilities

There is the potential for strong winds on Sunday over the northern Rockies, including areas around Browning, Heart Butte, East Glacier Park and the Cut Bank areas.

West winds will begin to strengthen Sunday morning along the Rocky Mountain Front and over the immediate adjacent plains, becoming strong and gusty during the afternoon hours before slowly decreasing through the evening hours. There is an 80% or great chance that wind gusts will exceed 55 mph along the US Hwy 2 corridor between Cut Bank and East Glacier over this timeframe, with a 50-80% chance that gusts exceed 65 mph. Those traveling on Sunday should be prepared for strong cross winds, especially if operating a high profile vehicle.

Recent mild weather has resulted in the early onset of spring activities. So with with hard freezes expected each morning through Saturday, don’t forget to protect any temperature sensitive pipes, plants, or pets. #MTwx
