Happy Tuesday,

Lenticular clouds or mountain wave clouds formed off of Montana’s mountains today ahead of an approaching storm.  It was fairly warm and windy across Big Sky today, but chillier changes are coming for the rest of the week.  Wednesday, a cold front will move through western Montana with a few showers and mountain snow showers.  Highs will be in the 40s and 50s in western Montana, 60s and 70s in the central and eastern areas ahead of the front.  West wind will pick up to between 20-40mph at times, so the wind will make it feel even cooler.  Thursday, a chilly airmass will settle over the state with enough instability for scattered snow showers to pop.  A little accumulation is possible over the mountains, and a few of the snow showers in the lower elevations could briefly come down at a moderate rate.  Highs will be in the 40s to around 50, but 20s and 30s in the mountains.  Friday, a more organized low pressure could produce several hours of light snow in central and western Montana.  A light accumulation is possible in the lower elevations, with a couple inches in the mountains.  Mountain passes will be a little slick by Friday evening, but travel should not be impacted significantly by this storm.  Highs will be in the 30s and 40s, but 20s in the mountains.  Saturday, a few snow showers could linger but the storm will be clearing.  Highs will be chilly in the 40s, with a west wind up to 20mph.  The mountains will be cold in the 20s and 30s.  Sunday will be warmer with more sunshine, and that mild weather will continue into the beginning of next week.

Have a great day!
