The work week has kicked off with cooler temperatures. North-central Montana will stay below average today, with highs in the upper 60s and low to mid- 70s. Scattered showers in central Montana will continue through the afternoon, pushing eastward. Locations west of Lewistown will stay dry for the remainder of today and Tuesday.
High pressure building over the western United States will result in calmer conditions and a gradual warm-up through Wednesday. Thursday, as a Canadian cold front makes its way into Montana, we'll have another significant cool-down, similar to last Thursday's temperature drop. Along with the cold front, moisture moving in from the west will create the possibility for thunderstorms across the state, especially in southwest Montana. These should be generally quick-moving, not producing a large amount of precipitation.
Cooler, rainy conditions won't last long, as another high-pressure ridge builds over the western half of the continent. Warm and dry conditions will dominate for the the holiday weekend.
