A WINTER WEATHER ADVISORY has been for portions of southwest Montana.
The state ended the month of January with above-average temperatures; we will go into the first day of Black History Month with daytimes highs trending 10-20 degrees above-average. A ridge of high pressure will dominate the region for the next couple of days and will offer mostly sunny skies. Tonight going into tomorrow, snow will develop in portions of northwest Montana.
Tomorrow will be the "warmth" before the cold. Daytime highs will reach the 50, and low 60s; record-breaking warmth will be possible for portions of north-central and eastern Montana. A cold front will result in a pattern change and will open the door for and a wintry mix of rain/snow. The highest accumulations are expected in the mountains of southwest Montana and along the Continental Divide.
Waking up Wednesday morning, many locations will wake up to snow. The lower elevations in southwest Montana could see between 3-5," and the lower elevations in central Montana accumulations will stay under 3" Mountain Passes such as; Marias, Chief Joseph, Kings Hill, Bozeman, and Raynolds Pass roads will be covered with snow and blowing snow could reduce visibility at times. Behind the passage of Tuesday's front, Wednesday's high temperatures will cool 15-25 degrees.
Thursday, a northerly flow will move colder air into the state. Daytime highs will remain in the 20s and 30s.
Friday, a potent cold front will bring frigid cold temperatures, overcast skies, and snow.
Superbowl weekend will likely be enjoyed inside, as daytime highs fall into the single digits and teens.
Happy Black History Month.
