Big fluctuations on temperatures!
A strong cold front will enter the region late Thursday and Friday, with big swings in temperatures both in front of and behind it!
Variable cloudiness Tuesday evening with some clearing by Wednesday morning. Lows in the upper 40s to lower 50s. Partly sunny Wednesday and warmer, especially west of the divide. Highs will soar into the 80s to lower 90s, which is above normal for this time of the year.
A moist southwest flow will bring a slight threat of thundershowers late Wednesday across southwest Montana. The threat will start increasing west of the divide by Thursday night and Friday. Some storms will be strong, bringing the threat of strong winds, lightning, small hail and locally heavy rain.
Much cooler behind the front. Highs will drop to the 50s and 60s by the weekend with a few showers. Snow levels will lower to around 5500 feet.
