The severe weather tracker is yellow indicating moderate impacts are likely around Kalispell and northwest Montana for a period of storms along with windy weather.  It is green with lower impacts for west central and southwest Montana with only an isolated storm possible.

WIND ADVISORY for northwest Montana, including the Flathead and  Mission Valley, for late Wednesday night and Thursday.  West southwest winds 15 to 30 mph with gusts up to 40 mph.

A strong storm is located near Seattle with a cold front parallel to the coast.  Both will slowly move through western Montana late tonight and Thursday.  A few showers and isolated thunderstorms are possible Wednesday evening between Missoula and Butte.  A better chance of showers and storms will occur overnight across northwest Montana around Kalispell with partly cloudy skies elsewhere. Showers will linger across northwest Montana on Thursday. Windy and cooler behind the front late tonight and Thursday.  Generally, we all can expect west winds 15 to 25 mph.  However, stronger winds are expected across northwest Montana.  Partly sunny on Thursday around Missoula, Butte and Bozeman.

Glacier National Park will be highly impacted by this storm.  After thunderstorms Wednesday evening, cooler air will lower snow levels to 7000 feet in the park.  Strong winds are expected, with gusts up to 60 mph at Logan Pass.  Tourists will need to use caution in the park.

Friday will be a beautiful day with sunshine and highs in the 70s.  Enjoy the cooler weather because a big warming trend will begin over the weekend.  Highs will warm into the 80s to lower 90s by Sunday and most areas will be in the 90s next week.
