BOZEMAN – High-pressure continues to build over the region producing warming temperatures and mostly dry conditions. There is a weak disturbance sitting over western Montana this afternoon and there is a slight chance for a few spotty showers.
Temperatures should climb into the 70s and 80s Thursday and with stronger surface heating there could be a few isolated mountain thunderstorms Thursday afternoon into Thursday evening.
By Friday a much stronger SW flow aloft will push temperatures well above normal into the 80s but a few upper 80s are possible locally.
Watch for increased snowmelt by the end of the week and higher river levels this weekend.
The next weather maker will be a Pacific cold front slowly moving into western Montana Friday evening and reaching SW Montana Saturday morning into Saturday afternoon. Ahead of this storm surface winds will be increasing Friday into Saturday. Wind gusts 30+ mph is possible Saturday afternoon.
Scattered showers and thunderstorms are also likely as the cold front moves into SW Montana Saturday afternoon. Once the front passes cooler temperatures and showers are likely Sunday.
