A WINTER STORM WARNING has been issued for the Glacier area including Marias Pass.
A WINTER WEATHER ADVISORY has been issued for areas along the Canadian border and along the Continental Divide.

Snow is headed back into Big Sky. This storm will not be a huge snow producer, but a return to winter-like driving conditions is on the way. Low pressure will move in from the Pacific Northwest through Tuesday. Initially a scattered mix of rain and snow will fall through the morning hours. There will be more snow during the day up along the Hi-Line. Highs will be in the 30s and 40s, which is above freezing. Roads will be wet for most of the day, but as the sun goes down the temperatures will drop Tuesday evening. This is when more snow will spread through most of the state. Snow will be light, but it will accumulate several inches in the higher terrain and out along the Canadian border. Wednesday morning will be slippery with light snow falling over frozen roads. Snow will gradually diminish through Wednesday morning. Temperatures will remain cold, highs will only reach the 20s and low 30s. The storm will clear for Thursday which will be mostly sunny and brisk, highs will top out in the 30s to around 40. A little warmup is in store for Friday and the weekend. Highs will warm back into the 40s and 50s through Sunday. This warmup will come with stronger wind across the prairies and mountains. Later on Sunday a cold front will spread some snow showers but signal an overall pattern change. Colder temperatures and more frequent snow is likely the week of Thanksgiving into the first week of December. Winter may be here for good this time.
Have a nice day.
