Enjoy the warm before the storm. Thursday will be another balmy November day with highs in the 60s and 70s along with strong wind. Gusts along the Rocky Mountain Front could top 80mph. Most areas will see gusts between 30-50mph. The wind, low humidity and drought conditions in southwest Montana will create dangerous fire weather conditions there, including the Boulder area. Friday will be not be as warm or windy, with partly to mostly cloudy skies and highs in the 50s. The only area with precipitation will be northwest Montana and the East Glacier area. The big storm arrives later on Saturday. A mix of rain and snow will spread south and east through the state in the evening. Rain will change to snow, which will be heavy at times through the overnight. Sunday, a powerful area of low pressure will move up through Montana. Snow will be widespread and heavy at times. This storm will produce a lot of wind, and blowing snow will reduce visibility to near 0 at times. Blizzard conditions are likely in central and eastern Montana through Sunday afternoon and evening. Travel will be treacherous, some roads will be impassible. Significant accumulation and drifting is likely into Monday morning. The worst will likely be northeast Montana. This will be a nasty, dangerous storm so please prepare accordingly. Monday will have slow clearing after a few areas of snow lingering into the morning. Another round of snow showers are possible Tuesday. Beyond that, temperatures will be consistently cooler than normal for the rest of next week.

Have a great day.
