MISSOULA — A fast moving weather system will bring light snow to western Montana Wednesday morning. Valley accumulations will remain light, however, the timing of this system may allow for some snow to accumulate on area roads just in time for that morning commute. Mountain passes such as Lookout, Lolo, Lost Trail and Marias can expect 2"-to-5" of new snow this morning.

Mostly cloudy skies along with a few snow flurries will be possible Thanksgiving. Other than that expect a mostly dry day with highs in the middle to upper 30s.

Starting Friday and continuing through the weekend, a strong area of high pressure will build over the western half of the United States. This will lead to an overall nice weekend with highs in the 40s and mostly to partly sunny skies.

The one thing to keep in mind, with high pressure building, valley fog and freezing fog will be possible each morning. If this strong high pressure ridge spans 5+ days and continues into next week, the result could be valley inversions leading to daylong freezing fog, cold valley temperatures along with impacts to air quality. We will continue to watch this to see how it plays out leading into next week.
