DISCUSSION

Issued at 1217 PM MDT Sun Jul 12 2026

Above-normal warmth will persist for the foreseeable future with daytime temperatures and heat risk peaking today across Southeast Idaho. HEAT ADVISORIES and EXTREME HEAT WARNINGS remain in effect through Monday evening. We still stand a chance of breaking all-time records for daytime highs today at Pocatello and Idaho Falls. The all-time record high temperatures for our official climate sites are as follows: 104 in Pocatello, 102 in Idaho Falls, 107 in Burley, 103 in Challis, and 96 in Stanley. Vulnerable populations or anyone exposed to the elements for long periods of time could experience heat-related illness if precautions are not taken. Overnight lows tonight will span the upper-50s to low-60s across the lower elevations.

Beginning tomorrow, a trough descending out of Canada will shift the area of high pressure slightly further east for the remainder of next week. This will mean a return to daily isolated to scattered convection and slightly cooler, fairly stable temperatures under increased cloud cover. Isolated showers and thunderstorms will arrive as early as Monday evening. Storms will trend wetter and more scattered in coverage heading into the middle of next week as PWATs begin to approach 0.75" on Monday and just over an inch by Wednesday.
