.SHORT TERM...Today through Saturday...A dry west-northwest flow
aloft will keep skies mostly clear through Saturday. Temperatures
will remain near normal.

.LONG TERM...Saturday night through Friday...Westerly flow aloft
through the weekend bringing seasonal temperatures and mostly
clear skies. By Monday afternoon, an upper low sitting off the
California coast will push some moisture up from the south which
brings a slight chance of precipitation along the Idaho/Nevada
border. Sky conditions for the eclipse still look favorable for
much of the CWA. Smoke and haze from wildfires could still be a
concern and should be monitored. This upper low continues to spin
off the California coastline Tuesday increasing chances of
precipitation for the southern portions of the CWA. Another upper
low begins to make its way southward from the coastline of British
Columbia. This low brings much more moisture and instability
increasing chances of precipitation across the CWA. Unstable
conditions persist through Friday morning then begin to dry out as
this feature pushes eastward.
