MISSOULA — Expect another dry and cool day Tuesday with highs in the upper 20s to low 30s. Once again, low lying clouds and fog may form in the valleys.

Areas in northwest Montana may see cloud cover linger throughout the day Tuesday. Areas in west-central and southwest Montana will see mostly to partly sunny skies.

Our next system will bring snow showers back to the forecast Wednesday afternoon through Thursday morning.

Mountains along the Montana/Idaho border in west-central and northwest Montana will see the most snow with 4"-to-8" possible over Lolo and Lookout Pass.

The best chance for accumulating valley snow will be along the Montana/Idaho border in northwest Montana.

Snow amounts will then quickly decrease the further south and east you travel.

Right now snow totals look like this:

Kootenai/Cabinet Region: Total snow accumulations of 3"-to-8" west of Libby near the Idaho/Montana border. Total snowfall accumulations of 2"-to-4"east of Libby along Highway 2 and 37.

Lower Clark Fork Region: Total snow accumulations of 3"-to- 7" along Highway 200 northwest of Thompson Falls. Total snow accumulations of 3"-to-8" along I-90 west of Saint Regis to Lookout Pass. Snow accumulations of up to 2 inches from Huson to Saint Regis.

West Glacier Region: Snow accumulations of 2"-to-4".

Seeley Lake/Potomac Region, Flathead Valley: Snow accumulations of 1"-to-2".

West Central and Southwest Montana: No to very little snow accumulation expected.

An active weather pattern looks to set up this weekend as a series of storm systems move off the Pacific Ocean.

The mountains, particularly along the Montana/Idaho border could see moderate to heavy snow at times.

The valleys will pick up very little in the form of snow as warmer temperatures in the upper 30s to low 40s will keep precipitation as a rain/snow mix or all rain.
