Brianna Juneau has the full forecast:
WEATHER DISCUSSION: Cooler temperatures began today for western portions of the state as a closed low begins to move overhead. This peaked high temperatures in the 50’s and 60’s for western and central areas while eastern areas saw high temperatures in the 70’s. There was a brief break in precipitation for most central, eastern, and lower elevations areas with partly cloudy skies and high wind gusts. Low temperatures fall into the 40’s and 50’s tonight with cloudy skies and rain becoming likely.
An anomalously strong summer storm will continue to bring widespread impacts to the Northern Rockies through Sunday night. These impacts include but are not limited to: accumulating snow to as low as 5000- 6000ft across all of Southwest through North Central Montana; high winds along and north of the Hi-Line in North Central Montana; and cold (for June) temperatures with the potential for overnight lows to fall below freezing across lower elevations.
Outside of Glacier, Toole, and Pondera Counties, most areas have seen a break from the precipitation today, with the strong and gusty west winds being the biggest concern. By this evening the lull in precipitation will come to an end as rain and mountain snow begin to overspread mountains in SW MT and the Rocky Mountain Front. These two areas of precipitation will expand in coverage through the remainder of the overnight hours, with widespread rain and mountain snow expected through the afternoon/early evening hours on Sunday. High temperatures Sunday are only expected to reach into the 40’s and 50’s.
From Monday through next Saturday, a return to more typical June conditions is expected. Afternoon temperatures will warm to slightly above normal by Wednesday, which will then continue into next weekend. The chance for showers/thunderstorms will become more isolated as we go later into the week. There will be chances for thunderstorms, but the overall strength of the upper-level disturbances to produce the precipitation will be on the weaker side, thus the more isolated potential for storms.
