Showers and thunderstorms continue through the afternoon and evening, eventually heading east to Bozeman in the early morning hours of Memorial Day. Temperatures overnight will be milder, in the upper 30s and 40s.
Memorial Day will be cooler with highs in the 50s and 60s. Showers are possible in Glacier Park, Helena, and even as far south as Bozeman. For the most part however, it will be a dry, pleasant day in our part of the state. A few isolated sprinkles and partly cloudy skies stick around Tuesday.
From mid-week onward the story is all about the heat. A full-fledged heat wave will kick of June with highs reaching the 80s Thursday and Friday. Even more hot weather is expected next weekend. It's becoming more and more likely that we will see 90 degree temperatures for the first time this year within the next several days.
