Predictive Services Discussion:

A strong upper low will continue to slide south in the Pacific Northwest, further lowering temperatures across the 

northwestern US. Scattered precipitation is expected across the Northwest, mostly along and east of the 

Cascades, Idaho, Montana, northwest Wyoming, and northeast Nevada. Snow will be likely above 7,000 feet, 

and snow levels could drop below 6,000 feet in areas. Gusty north-northeast winds of 15-40 mph will develop 

west of the Cascades into northern California and while temperatures will be below normal, drier air aloft will 

lower relative humidity to 25-50% in areas overnight, especially at mid and upper slopes in southwest Oregon 

and northwest California. Dry and breezy conditions will develop across portions of the Great Basin and spread 

into the Desert Southwest and West Slope ahead of the upper-level trough and cold front. Isolated thunderstorms 

are likely in portions of the northern Rockies and from the central Sierra extending northeast into western 

Wyoming, with mostly isolated thunderstorms from southeast Arizona into southwest Texas. Another round of 

thunderstorms is expected on the southern Plains extending into the Lower Missouri Valley, with isolated to 

scattered thunderstorms across portions of the central and northern Plains into the Upper Midwest. 

Thunderstorms are likely from the central Gulf Coast to the Southeast Coast, including across Florida, with low 

relative humidity continuing in portions of the Southeast and Texas.
