DISCUSSION

Issued at 152 AM MDT Sat Aug 1 2026

Hot dry weather expected today. Many areas will be approaching record highs today with triple digits possible. Winds pick up some this afternoon, especially across the central mountains into the upper Snake Plain which may be the only relief from the heat. Heat advisories are in effect for much of the region that will be flirting with triple digits and for those mid elevation communities such as Driggs and the Bear Lake area where mid 90s aren't as common. A dry cold front arrives for Sunday. This will roll back temps nearly 10 degrees in some places. Sunday is windier, but probably still holding under wind advisory levels. The HRRR smoke models shows another round of smoke moving back into the area. Dry weather continues into early next week with highs falling into the 80s across much of the region for Monday and Tuesday.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1221 PM MDT Sat Aug 1 2026

VFR conditions expected through the period. Gusty SW winds will be the only issue to aviation over the next 24 hours. Gusts upwards of 20-25 kts will be possible at all sites except KBYI where winds likely won't exceed 15 kts. Skies should be mostly clear to mostly sunny with no precipitation expected as drier air has moved into the region.

FIRE WEATHER

Issued at 152 AM MDT Sat Aug 1 2026

Red flag warnings are in effect for Saturday and Sunday for much of the Snake Plain, eastern Magic Valley and central mountains for the combination of low humidity and gusty winds. Humidity values could fall into the single digits with hot temperatures in place on Saturday. Wind gusts likely in the 25 to 30 mph range in the red flag area. On Sunday, cooler temps will allow humidities to be slightly higher. However, probably still lower teens in many areas with wind gusts in the 25 to 40 mph range.
