It will really start to feel like Summer again today and for the next couple of days.
Temperatures today will top out in the upper 70s in the Flathead Valley and the Butte area, low to mid 80s for Bozeman and Missoula, and upper 80s for the Plains/Thompson Falls area and Lincoln County. Afternoon cloud cover south of I-90 could produce an isolated sprinkle. Lows will be much warmer heading into Wednesday, in the 40s to near 50 degrees.
A slight chance of a shower or thundershower is possible in Southwest Montana late Wednesday as a Pacific storm system approaches from the southwest. The biggest push of moisture will be on Thursday and rain chances will increase both Thursday and Friday with a chance of a thunderstorm along with rain on Thursday.
Temperatures will remain in the upper 70s and 80s through Thursday before cooling off for Friday and the weekend. Friday looks to be the coolest day of the week with some areas not getting past the upper 60s.
