Friday and this weekend will be cold and sunny with light winds. Bluebird but cold days will bring great carving conditions on the slopes across Oregon. Next week will continue to be dry and cold as the upper-level ridge and high pressure remain semi-stationary. A storm is possible by late next week and weekend but model uncertainty remains.

The big story this weekend will be arctic air overspreading much of the Lower 48. The large-scale pattern will continue to favor drier conditions across the West with only some light snow for the Rockies, while the East will be more active. Two storms will move across the East over the next 3 days, while the South could see snow next week. The Great Lakes will also see consistent snow showers.

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.

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.
