DISCUSSION

Issued at 120 PM MDT Sun Jul 26 2026

Thunderstorms not expected to be as widespread this afternoon and evening as last couple of days. Heat advisory will expire this evening and will not continue it as Monday looks to be cooler a bit despite very hot still. Starting to see some wildfire smoke overtake western areas into Burley this afternoon and added in some smoke to grids through Monday. Expect a moisture increase with continuing southwesterly flow aloft with a higher chance of showers and thunderstorms Tuesday and Wednesday mainly in higher elevations. Models indicating drying and warming with extreme heat back in play Thursday into next weekend. Low elevation highs back into the upper 90s to around 100 again by Friday and Saturday. But overall this extremely hot July will continue through the end of the week as it will remain well above normal temperature wise all the way to the end of the month.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1152 AM MDT Sun Jul 26 2026

Latest indications are that TSRA activity will be limited to the early evening at KIDA and KPIH, and afternoon to early evening for KDIJ. Strong gusty outflow would be the main problem other than lightning, with nothing impactful expected to CIG or VSBY. Cloud bases are at 600mb or above. Cirriform clouds increase during the overnight hours, and after midnight should constitute a CIG for KDIJ, KBYI, and KPIH. By 27/12Z the CIG will have reached KIDA and KSUN as well. Still at mid-level elevations and higher, there should be some -SHRA during the morning, starting as early as 27/11Z. The TSRA threat is low in the morning, but may have to be monitored. The extensive mid- and high level cloudiness will cool temperatures but without increasing the risk of TSRA.

FIRE WEATHER

Issued at 103 AM MDT Sun Jul 26 2026

Near critical winds/rh exist this afternoon across the central mountains into the Snake River Plain. Could be near critical conditions for wind and rh once again on Monday for the same areas.
