BUTTE – An unsettled weather pattern continues Monday into Tuesday with a variety of afternoon and early evening thunderstorms. Most storms will be on the weaker side but a few could be stronger. Regardless of intensity, all thunderstorms could produce brief heavy rain, small hail, frequent and deadly lightning, and strong outflow winds.

Summer officially begins on Friday. Longest days of the year are here, however, as we welcome the summer solstice a weather pattern change will be impacting most of the western U.S. with below normal temperatures and above normal precipitation.

There is a good chance for higher mountain snow across Montana Thursday through Saturday. Plan accordingly if you have outdoor plans especially if you are venturing into the backcountry.
