A cold front will pass through Idaho today, bringing winds in the 10-20 mph range with gusts to 35 mph in southern Idaho, and precipitation to much of the state. Northwest winds aloft are not expected to bring smoke into the state. These conditions support continued clearing and scouring of smoke from the atmosphere.
Light smoke from fires in Oregon look to skirt around the southwestern portion of the state which may briefly pass over Owyhee County. Local smoke impacts are possible tonight around the Central Idaho Mountains as winds turn northerly and track smoke south across Boise County and Elmore County into the Snake River Plain. These impacts are not expected to be widespread or long-lasting and will dissipate with the breaking of the morning inversion.
MODIS AQUA-Visible Satellite imagery 08/30/20 indicates smoke to the south of Idaho with clear conditions over the entire state outside of a single plume in the Central Idaho Mountains.
