Clearing in southern Idaho

Air quality forecasts for today are in the Good to Moderate Category.

A cold front will pass across southern Idaho and scour smoke from the area and a westerly flow pattern will reduce smoke coming into Idaho. Air quality will improve from west to east, with conditions dropping into the Good/Moderate category tomorrow by noon in eastern and southeast Idaho. Periodic smoke surges will affect the southern Panhandle and the Palouse periodically tonight and tomorrow morning.

Smoke coming back

Air quality forecasts are in the Good to Moderate Category.

Concentrations look to build over all of southern Idaho, first affecting the Southern Highlands, Southeast Highlands, and elevated terrain of the Central Idaho Mountains. By 6pm MDT, conditions look to engulf all of south Idaho, outside of a sliver within the Treasure Valley and Payette and Weiser Valleys. Smoke looks to reach all areas south of a line running between Cascade and Salmon. This smoke will clear from west to east beginning tomorrow around noon.  North Idaho will see two distinct pulses of smoke during the forecast window, the first occurring around 2pm PDT and affecting the LC Valley and the Spokane-Coeur d’Alene corridor.  This wave will track east with brief clearing behind it as a dry cold front passes through. By 3am PDT tomorrow morning, a secondary wave will track into the Panhandle and across the eastern portion of northern Idaho, primarily impacting Shoshone and Clearwater Counties before clearing around 7am PDT.

Air Quality Advisory lifted for south central and southeastern Idaho

 

Clearing today!

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

Northwest flow and precipitation will help keep skies clear in North Idaho and will begin to clear southern Idaho today. Conditions will begin to improve around noon today and continue throughout the evening from west to east. 

Eastern Idaho will begin to see improvement by around 1 p.m.  This flow pattern will keep the state clear tomorrow and into Sunday. Late Sunday, smoke will begin to build along the Idaho border with Nevada as a west to southwest flow pattern becomes established. That flow will become more southwesterly on Monday, allowing smoke to enter southern Idaho. North Idaho looks to remain clear, outside of any local fires.
