Beautiful but toasty day today but changes are coming at the start of next work week.
Sunday, mostly clear skies for the Snake River Plain and central mountains with highs in the upper 80's and low 90's. Few more clouds in the southern highlands with the possibility of a dry lightning storm or two, meaning fire danger will be elevated.
Monday - Wednesday, subtropical moisture moving in from the south means lots of scattered thunderstorms with heavy rains. Daytime highs in the mid 80's for the Snake River Plain, and mid-70's in the high country. Expect breezy conditions Monday evening and Tuesday as a front rolls through.
