MISSOULA — A low pressure system will become almost stationary and settle over the northern Rockies Monday and Tuesday. This will bring widespread rain, high mountain snow and cool temperatures to western Montana.
Heavy rain will be possible especially in west-central and southwest Montana Monday and Tuesday. This will lead to rising rivers and streams where flooding is likely. A Flood Watch has been issued for most of western Montana starting this afternoon and continuing through Tuesday night.
A winter weather advisory is in place through noon Monday for snow in the mountains of southwest Montana. Locations above 6,500 ft. could see up to 2" while areas above 7,500 ft. could see up to 6".
Scattered rain showers and thunderstorms remain in the forecast Wednesday, however, rain will not be as widespread or heavy.
By Thursday the low pressure system will move out of the northern Rockies and by the 4th of July weekend, all the rain, snow and cool temperatures will seem like a distant memory. Expect sunny skies with highs in the 70's again Thursday then 80's move in Friday and continue through the weekend.
