South Idaho sees a break, North Idaho still impacted

Air quality forecasts today are in the Good to Unhealthy for Sensitive Groups category. 

Smoke impacts will be focused in central and north Idaho today and through the weekend. An active weather pattern over south Idaho should provide plenty of precipitation and  higher winds ventilate and scour the air. Easterly winds will transport smoke from central Idaho into the Snake River Plain before any storm activity today. High pressure and cyclonic flow will transport smoke around north Idaho. 

The highest concentrations should be in the Panhandle shifting east to the Montana-Idaho border south through Shoshone, Clearwater, and Idaho Counties into Valley County this evening. This smoke will drain into the Lewis-Clark Valley and across the Weippe and Camas Prairies tonight into tomorrow morning with substantial concentrations expected along the Idaho-Washington border from the Canada to Lewiston. 

This smoke will continue to shift east tomorrow with locally high concentrations near fires in Montana and east-central Idaho. On Sunday, smoke will impact all areas north of Idaho County. Monday is likely to have similar impacts and weather with increasing smoke in southwestern Idaho as southwest flow begins to develop.

HRRR-Smoke: Near surface smoke forecast initialized 12Z (6am MDT) and valid 07/31/21 at 03am MDT shows ample smoke at the surface across north Idaho will clear conditions over southern Idaho.
