A very warm summer day is expected Wednesday. Highs reach the upper 70s around Butte and low 80s elsewhere. A few areas in Sanders, Mineral, and Lincoln counties will reach the upper 80s along with the Drummond area.
There is a slight chance of a shower or thunderstorm across Southwest Montana late this afternoon as another round of moisture moves in ahead of an approaching Pacific storm system. Conditions clear again overnight.
The biggest push of moisture comes on Thursday as the system heads inland, bringing us the best chance of a shower or thunderstorm area wide. Highs will drop into the 70s Thursday and into the low 70s and upper 60s on Friday. The best chance for rain will once again be in Southwest Montana with some parts of the northwest corner of the state seeing no rain at all.
Above average temperatures return late in the weekend and continue through the beginning of next week.
