A departing storm brought a final surge on Friday to the I-70 corridor under NW flow, pushing snowfall north of the San Juan Range over the I-70 corridor and north to Steamboat. A new storm in the PNW on Saturday will crank out 20-50 inches, with the highest totals in Oregon. Idaho, MT, Tetons seem favored next for the leftovers. A new storm moves into the Sierra early next week and pushes east.
Storm 1 of 3-part storm cycle is done with 12-21 inches of snow as of Friday morning. Storm 2 will bring snow throughout Friday and into Saturday morning with 10-20 inches of snow above 3,000 feet. Storm 3 will bring the strongest AR yet with variable snow levels from northern Oregon (3-4k) to southern Oregon (4-6k). Total 3-day snow accumulations from Friday to Sunday will be 1-4 feet.
An active pattern will continue across the West with multiple strong storms expected this weekend and next week. All major ski regions from the Southwest to Canada are favored. The East will remain in a spring-like pattern with rain expected on Sunday.
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.
