What a beautiful stretch of weather for Big Sky Country. Warm, sunny days, clean air, starry nights, and dry weather has been rule of thumb since the weekend. Beautiful late spring weather will continue for one more day before big changes start on Thursday. Wednesday will be another sunny and warm day with an afternoon breeze picking up to around 20mph. Air quality will be good. Wildfires in Canada continue to burn, but the wind flow is keeping smoke off to the north of Montana. Thursday, a strong cold front will move through the state in the afternoon and evening with big thunderstorms. Some of these storms could be severe with large hail and damaging wind. Behind that front, Friday will be much cooler with rain and thunderstorms. Snow levels will once again become an issue as flakes will start flying in the mountains above 7000′ but fall to mountain pass level by Friday afternoon. An accumulation of a few inches is likely in the highest terrain. Highs on Friday will only be in the 50s and 60s, but 30s and 40s in the mountains. Saturday is a big day with the Governor’s Cup in the Capital. Right now the heaviest of the rain should be off to the east, but showers and wind will continue for most of the day. Early morning temperatures will be in the 30s and 40s, with afternoon highs in the 50s to around 60. Sunday will start out partly cloudy but scattered showers and thunderstorms will move through in the afternoon and evening. Drier weather will develop into next week.
Have a great day!
