Upper-level troughing will deepen along the West Coast as an upper low approaches and moves into southern British Columbia, and an associated cold front is forecast to move through the Pacific Northwest into the northern Rockies, northern Great Basin, and northern California.

Breezy west winds are likely in northeast California where fire potential remains elevated, with breezy winds also expected across the eastern slopes of the Cascades and Columbia Basin.

Isolated to scattered showers and thunderstorms are expected across portions of Idaho, Montana, Wyoming, and into the central Great Basin and Colorado Rockies. Additionally, showers are likely in western Washington and northwest Oregon.

Thunderstorms are expected on portions of the central and northern Plains into the Midwest, including some severe storms, with potentially heavy rain in the northern Great Lakes. Downslope flow off the southern Rockies will likely result in dry and breezy conditions in southeast Colorado and eastern New Mexico, and dry and breezy conditions are possible in portions of Kansas into Nebraska, Missouri, and Iowa. Thunderstorms are also likely along portions of the Gulf Coast.
