A few weak disturbances will bring clouds and an isolated chance of a shower into our otherwise warm and sunny pattern over the next couple of days.
Wednesday begins with lows in the 30s and 40s, followed by mostly sunny to partly cloudy skies with highs in the 70s and low 80s. Missoula will be close to 80 degrees Wednesday afternoon. An isolated shower or storm is possible around Butte and Bozeman in the afternoon. Outside of one or two storms, expect sunshine.
Thursday will be slightly cooler, with most areas only reaching the low to mid 70s under partly to mostly cloudy skies and breezy conditions. Morning sprinkles are possible in Kalispell, while isolated storms are possible in central Montana in the afternoon. Most of us will only notice the wind.
Friday begins the heart of the upcoming heat wave. Highs soar into the 80s for most locations, and parts of Lincoln and Sanders counties could hit 90 for the first time this year. If they don't on Friday, those areas will hit 90 over the weekend. Many of these areas will be close to record temperatures.
Hot, sunny weather is expected through Tuesday, with many valleys west of the divide hitting or getting close to 90 degrees betweeen Saturday and Monday.
It will be a few degrees cooler in the middle of next week, but for now most of us should still expect sunny skies.
