Light showers will gradually taper off across the state tonight, setting us up for a cool yet pleasant morning with lows in the low to mid 30s. Conditions will remain dry for most of the day with only light sprinkles possible Monday afternoon. Highs will reach the upper 40s and low 50s.
Cloud cover will increase ahead of a quick-hitting storm that sweeps at around sunset on Monday. Mountain passes and areas above 5000 feet (Butte, etc.) will see some snow or a wintry mix, but it will have minimal impact. Look for Bozeman pass will likely be wet and/or slushy on Tuesday morning since this is a good setup for heavier showers around the Bridger Range.
Showers will dissipate Tuesday and a strong ridge of high pressure will set up across the northwest Tuesday afternoon through Friday. This means a couple of things. First, there will finally be consecutive days of sunshine for the first time in weeks. Second, our long period of below average temperatures is over. In fact, we're expecting well above average temperatures late in the week. Many areas will hit 70 or above for the first time this year on Thursday. Some spots will reach the upper 70s either Thursday or Friday.
Expect more toasty temperatures on Friday and also a threat of thunderstorms if you live near the Idaho Panhandle. Cooler weather follows behind it for the weekend. Thunderstorms will be possible all next weekend around Butte and Bozeman.
