Main impact through tomorrow will be smoke impact with Air Quality Alerts in effect for several counties. Strong west to southwest flow has brought in the smoke and expect it to remain Monday as flow aloft shifts more northwesterly with several western wildfires ongoing. Many Red Flag warnings still in effect as well due to wind and humidity through this evening. Will see significant cooling on Monday as an upper level trof works east through Idaho. Highs only in the lower 80s low elevations and 70s mountains. The below normal temperatures will continue through Tuesday then another warming trend begins Wednesday with low elevation high temperatures well into the 90s again by thursday with very hot conditions expected through next weekend once again. Will likely see upper 90s by next weekend in the lower elevations. Forecast grids have no precipitation anywhere through next Sunday.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1223 PM MDT Sun Aug 2 2026

Smoke looks to be problematic at area terminals through the period. NW flow aloft looks to bring in more smoke across the area throughout the day on Monday. Hard to say exactly how impactful it will be but based off of current observations, MVFR to IFR CIGs look likely through much of the period. Confidence is low however. There may be some slight improvement this afternoon / evening based off the latest HRRR smoke output with things degrading again after 02-04Z or so. Winds remain breezy in the valley terminals of KBYI, KIDA and KPIH with gusts in the 25-35 kt range expected into the evening.
