A strong low pressure or vortex continues to spin in western Canada. This low is big and has cold temperatures with it. This storm is also carving out a deep trough in the jet stream that will keep Montana cool and unsettled, with another shot of snow likely this weekend. But before then, temperatures will moderate over the next several days. May 1st will start out chilly with morning temperatures in the 10s and 20s. Wednesday will be warmer with isolated showers over the valleys and plains, and snow showers in the mountains. Highs will be in the 40s to around 50. Thursday will be slighly warmer with highs in the 50s, but scattered showers and a few thunderstorms will develop in the afternoon and evening. Friday looks like a beautiful day with mostly sunny skies and warmer highs in the 50s and 60s. Is the warmer air here for good?? No. Another strong Canadian front will drop south into Big Sky Country from Friday night into Saturday. Snow will likely be widespread again across northern Montana. Although it will be cold, snowy and breezy, at this time blizzard conditions are unlikely. Sunday’s temperatures will be slightly warmer with partly to mostly cloudy skies and a few scattered showers of rain and snow. Next week will be active with more rain showers and temperatures staying below average. This pattern likely will continue through the second week of May.
Have a nice day.
