The coldest air of the season will be knocking on the Rockies by later Friday through Monday. Snow amounts stay light to moderate, with a few spots near Boulder or the Divide north of I-70 on watch. The extended offers some hope.

Sunny days continue for at least another week...

An arctic cold front will move from north to south into the Western U.S. on Friday and Saturday before spreading into the Eastern U.S. early next week, resulting in some of the coldest air of the season so far in many areas. Storms will continue to favor the East from late this week through early next week, while the Rockies will see a shot of snow Thursday-Saturday as the front arrives.

Thanks for reading this summer! For the rest of this week, a cold front moving across the Central Rockies will bring showers & t-storms to WY, CO, & NM Wed-Thu while the West Coast states will see a late-season heat wave. Next week, isolated to scattered showers & t-storms develop across the West with continued mild temps. Heading into mid-month, the PNW will trend wetter and cooler.
