Weather Forecast: Dry and cool start to the week

Posted at 5:46 AM, Dec 28, 2020

MISSOULA — High pressure overhead will lead to valley fog and dry conditions to start the week. Fog will be most likely in northwest Montana and may stick around into the late morning or early afternoon.

For those that don't see fog expect mostly sunny skies with highs in the upper 20s to low 30s Monday and Tuesday.

Clouds will be increasing Wednesday as our next storm system approaches. Snow showers will start Wednesday night and continue Thursday morning. The highest snow totals will be found in the mountains along the Montana/Idaho border. The valleys of northwest Montana could see 1"-to-2" while west-central and southwest Montana valleys generally see less than 1".

By the weekend, we are looking at the potential for another "Atmospheric River" to set up. This means moderate to heavy snow will be possible in the mountains.

Valleys will once again see temperatures warm into the upper 30s to low 40s with this atmospheric river, leading to precipitation falling as a rain/snow mix or all rain.
