Smoke impacts today are expected to be extremely localized and greatest (while still remaining relatively light) over the central and southern Panhandle and south to Latah County while the remainder of the state is expected to remain clear with upper level haze evident over southern Idaho thanks to southwesterly winds and fires burning in CA/OR. Over night, drainage into the Upper Snake via the Big Lost and Little Lost should be expected, but will dissipate in the early afternoon.
This image shows expanded smoke coverage from the southern Panhandle and south into the Camas and Weippe Prairies. The rest of the state remained clear.
