Looks like a few more nice days ahead of our Thanksgiving Cold Front. Seems like every year, Montana gets a cold front just about the time we're hopping in our cars for holiday travels. A second wave of moisture could be arriving just in time for our drive home. The road surface temperatures have been slowly cooling off and it's time to expect the snow to begin sticking. It's not time to expect big snowpack yet, but icy roads are more than a possibility now. Freezing drizzle is also possible in north-western Montana. Tomorrow is National Gingerbread Cookie Day.
- The next two days looks fairly nice across Montana, but changes are ahead as a cold front is set to arrive Thanksgiving Day.
- Expect snow on the mountain passes and rain/snow across lower elevations including the possibility of some freezing drizzle in the north west.
- Another wave of moisture should be moving into Montana just in time for our drives home from Thanksgiving.
High pressure will continue to dominate the weather for Montana through Wednesday. Mostly sunny skies, with cool valley temperatures and cold nights can be expected. In addition, fog and low stratus will likely expand a bit each morning through western valley locations, especially across northwest Montana. Wednesday will be the final nice day, and an excellent travel day for those hitting the road or taking to the skies for the Thanksgiving holiday. The weather pattern will begin to change to a much wetter one starting Thursday, as moisture from the west moves into western Montana. Mountain passes, particularly Lookout, Lolo, Lost Trail will experience periods of moderate snowfall and winds, making for difficult winter driving both Thursday and Friday. During this same time frame, valleys still holding on to cold air from lingering inversions may experience a period of very light freezing drizzle early on Thursday. Conditions turn much colder Friday evening through Saturday, which is when valleys of western Montana could pick up their best chance at accumulating snow. This could impact Saturday morning travel, particularly since road surfaces should be cold enough to sustain impacts for a longer period of time. Forecast models continue to differ a bit on Sunday in the evolution of a shortwave trough passing through western Montana and central Idaho. If you have travel plans on Sunday, keep an eye out for further changes.
