Another Canadian cold front moving north to southwest overnight Thurs has brought back upslope snowfall to the Central and SW mountains. Showdown, digging out of 15” over the past two days, will add 24-hour totals of 5 – 7”. Big Sky, Bridger, and Red Lodge, around 3 – 5” thru Fri PM. Arctic temps return Fri – Sun. High-pressure then builds on Sat and amplifies and warms Sun through midweek.

A narrow band of snow (We call these Deformation zones) will set up over northern Colorado Friday night and move from east to west Saturday. These are hard to predict with any deviation of track. This Saturday, the most likely chase spots will range from north of I-70 in Colorado and areas from Sundance in Utah to the I-80 Corridor. This wave will drag over southern California later this weekend.

A storm will work its way into the Rockies from the north this weekend and will stall out over the Southwest through early next week with snow favoring Colorado, and to a lesser extent, Southern California and the Southwest U.S. The East will see a gradual warming trend with snow continuing to favor the Great Lakes region. The Northwest will finally start to see some snow at the end of the month.

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.
