            Key Points -Warm and dry through the weekend 
            thanks to high pressure at the surface and 
            aloft -Showers and thunderstorms expected 
            Sunday, some of which may produce gusty 
            winds -Cooler start to the work week, with 
            temperatures slowly warming through the week 
            - Meteorological Overview: Upper level 
            ridging and high pressure at the surface 
            will keep things warm and dry today and 
            Saturday with generally light winds across 
            the area. As such, temperatures will be the 
            main impact today and tomorrow, with warm 
            temperatures reaching the upper 70s today 
            before shooting up into the low 90s on 
            Saturday. While this is early for 
            temperatures this warm, the short nature of 
            this warm up, even combined with warm 
            temperatures on Thursday, doesn’t appear to 
            rise to the level of needing Heat Advisories 
            at this time. The warm and quiet stretch of 
            weather comes to an end on Sunday, as a cold 
            front pushes through the area, bringing a 
            round of showers and thunderstorms ahead of 
            fairly large cooldown for the first half of 
            next week. Most of these showers and 
            thunderstorms will generally be found in the 
            terrain of Southwestern Montana, where a few 
            gusty winds will be possible on Sunday 
            thanks to strong instability and very dry 
            air near the surface. Behind this cold 
            front, cooler, and somewhat unsettled, 
            weather will linger across North Central and 
            Southwestern Montana, with widespread rain 
            expected Monday as temperatures struggle to 
            get out of the 50s across the plains (though 
            the southwestern valleys will see 
            temperatures reach into the mid 60s. While 
            not as widespread, expect increased chances 
            of rain through next week as a series of 
            weak weather systems move through the area 
            through mid to late next week.
