SHORT TERM
Tonight through Sunday night...
An upper trough over the Pacific NW and northern Rockies will continue to bring near normal temperatures to the region through the weekend. A weak upper low off the California coast will get pulled northeast over Oregon and Idaho Saturday. Moisture is limited but there will be a chance (15-30%) of thunderstorms Saturday afternoon and evening near the Nevada border and over eastern portions of the Payette and Boise NF. Sunday looks dry across the forecast area. Breezy westerly winds Saturday and Sunday afternoon as a weak shortwave moves across northern Idaho. Smoke will continue to impact the region with southwest to west winds advecting smoke over the area from northern California fires in addition to our local fires over eastern Oregon and southwest Idaho.
LONG TERM
Monday through Friday...
Next chance of precipitation (15-20%) will be Monday night/Tuesday generally north of a line from around Burns to McCall as another weak Pacific trough sweeps across the region. This will kick westerly winds up again for breezy conditions Monday and Tuesday.
The great basin high is expected to rebuild late next week for a return to above normal temperatures Thursday and Friday with triple digit heat in the lower valleys.
