Possible clearing before more smoke this weekend

Smoke impacts today are expected to remain over southwestern Idaho primarily due to both local and regional fires. There will be widespread haze throughout the day, particularly over southern Idaho and the Panhandle due to regional transport of smoke. This evening, expect smoke to drain into the Treasure Valley and within the Purcell Trench across the Panhandle. Southwest winds aloft will continue to bring smoke into Idaho from fires burning in Oregon and California. Tomorrow, expect similar conditions and patterns with continued clearing before a stagnant atmosphere traps smoke this weekend.
