BILLINGS – Snow, rain, wind and thunderstorms are all possible with a storm system Tuesday.
A Pacific weather system will impact southern Montana and northern Wyoming on Tuesday, moving from west to east.
There is a good amount of available moisture and enough lift in the atmosphere to create isolated afternoon thunderstorms, especially east of Billings.
Snow and rain showers in the mountain foothills will change to all rain later in the day from Livingston toward Red Lodge.
A chance of a thunderstorm is higher closer to the Dakotas later Tuesday afternoon, from around Baker extending into northern Wyoming around Sheridan and Gillette. Wind gusts and perhaps some small hail would be the biggest threats.
High temperatures will be mainly in the upper 40s to mid 50s, and will trend slightly warmer Wednesday. Overnight temperatures will be mainly in the 30s.
As the storm system slides to the east overnight, the sky will clear from west to east. Winds will be gusty at times Wednesday afternoon with isolated showers.
We remain on track for a big warm-up later in the week.
