Quiet weather and freezing fog as high pressure arrives
A much quieter weather pattern is setting up for the last half of the weekend and into early next week. A strong high pressure ridge will be building in from the west. It will bring mostly dry conditions through midday Tuesday and temperatures near average for this time of the year.
Tonight, low temperatures will be in the upper 20s to near 30 in west central and NW Montana. Southwest Montana will see slightly cooler temperatures, in the low to mid 20s. Valleys west of the divide, such as the Flathead, Mission, Missoula, and Bitterroot Valleys will be subject to a chance of dense freezing fog tonight and into Sunday morning.
Temperatures Sunday will be in the 30s area wide. NW Montana will see mostly cloudy skies, but less clouds will be present as we head into SW Montana. Areas in the eastern half of southwest Montana, such as Bozeman, will see a chance of snowfall Sunday night. However, accumulations, if any, appear to be very light.
The next weather system that will bring widespread precipitation the area will come in late Tuesday night and into Wednesday. A steady stream of moisture will move in from the Pacific and cause widespread mountain snow. However, with high temperatures into the mid 30s, most valley locations will see a mixture of rain, snow, and freezing rain.
Rain and snow chances will stick with us through Thursday and Friday as well.
