Very warm temperatures have overspread the Cascades, and rain is falling in many areas. Colder air will overspread the PNW by later Saturday, bringing moderate to heavy snowfall to many places through Sunday. Leftovers will move into the Panhandle of Idaho and northern Montana before weakening over the Rockies. Moisture will continue mid to late next week, favoring northern areas of the west.

A strong storm remains on track for Southern BC with a strong west/southwest flow aloft favoring the Northern & Eastern Interior, especially Revelstoke and Kicking Horse. The storm has trended warmer for Whistler with a rain/snow mix at mid-mtn Friday night and lowering snow levels on Sat. A drying trend will occur early next week, with snow possible late next week.

The West will finally see a storm this weekend following an extended dry spell. The storm will favor the interior of Canada for the highest totals, while the Washington Cascades and BC Coast Range will start as rain before changing to snow. Lighter snow will fall in the U.S. Rockies. New England will see more snow this weekend with a combination of rain, snow, and mixed precipitation next week.

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.
