MISSOULA — High pressure continues through the weekend leading to sunshine and valley inversions. As stated all week, those that can break free of the inversions will see upper 30s to middle 40s. Those stuck under the inversions will see highs only in the upper 20s to low 30s.
High pressure looks to remain in place over the northern Rockies through Monday of next week.
By Tuesday, a shift in the jet stream will allow inversions to break and temperatures to actually warm. Highs will be in the mid to upper 40s Tuesday. Some locations in the Bitterroot Valley and northwest Montana along the Montana/Idaho border may even see some low 50s!
Looking at the long range forecast, temperatures will start to slowly drop by the end of next week and weekend. Several weak systems could bring the potential for snow showers back to the forecast, however at this time no major snow makers are on the horizon.
