It's the last weekend of summer and it will feel like summer again before the weekend is out. However, snow was flying in the mountains on Friday. The Beartooth Highway was closed on the Wyoming side because of heavy snow and the possibility of up to 24". That storm will slowly move away through Saturday and there will be improving conditions through the weekend. Saturday's highs will be cool in the 50s and 60s. If you're planning on heading up into the mountains, there's a chance you will run into snow on the ground early. Cool and wet conditions are possible Saturday. Sunday will be a much different day with beautiful sunshine and beautiful, warm temperatures in the 70s for highs. The mountains will be much warmer on Sunday as well with highs in the 40s and 50s. Monday is the first day of autumn and the nice weekend weather will continue into the start of the workweek. Highs will be in the 70s again with partly to mostly sunny skies. Tuesday a weak front will bring scattered showers. That storm is no big deal, but late in the week there will be a big deal. A large storm is likely late in the week with heavy precipitation and much colder temperatures. Thursday will have rain in the lower elevations but snow should fall and accumulate above 5000'. By Friday there is a likelihood that snow levels will drop to the valleys and the plains. Cold air and snow is possible into the final weekend of September. So in the span of a week Montana will go from summer to fall to winter.
Have a great weekend.
