A WINTER WEATHER ADVISORY has been issued for the higher terrain of central Montana into Friday.
A WINTER WEATHER ADVISORY has been issued for the Rocky Mountain Front and most areas west of the Continental Divide through Friday.

The "pineapple express" from the Pacific is headed to Montana and much of the West. This Pacific pattern usually and will favor areas west of the Continental Divide with snow and rain, but there will be some periods of snow east of the Divide into the weekend. Day to day and region to region there will be quite the variability across Montana. Thursday will have a large low pressure move into western Montana with mixed rain and snow in the lower elevations, and heavy snow in the mountains. East of the Divide will have wind, some showers, clouds and periods of sunshine. Highs will be in the 40s for most of Montana, with the exception of the 10s and 20s in the northeast part of the state. Mountains passes over western areas may be difficult to travel over. Friday will have more snow showers spread across the state, and temperatures will be colder. Don't expect much accumulation in the lower elevations east of the Divide. This weekend will have areas of light snow on Saturday with colder highs in the 20s and 30s. Sunday will have partly cloudy skies with scattered mountain snow showers. Highs will range from the 0s and 10s to the northeast, with 20s for the rest of the state. Areas of snow showers will continue next week as well. Although scattered light snow is likely into the weekend, there does not appear to be any monster storms on the horizon.
Have a great day.
