HOT WITH PM STORMS INTO NEXT WEEK:

High pressure has settled in over the Intermountain West and remains nearly stationary through much of the week ahead. This puts eastern Utah and western Colorado in a west/southwest flow regime allowing for plenty of warm air to continue to funnel across the region. As a result, unseasonably warm temperatures with valley highs in the upper 90s, low 100s are here to stay. Remain cognizant of the heat and pack an excess of water for your outdoor adventures.

Additionally, monsoonal moisture continues to slosh around underneath the high. This will support afternoon convection each day. Thunderstorms will develop over and favor the high country, with some showers/storms holding together as they move off the terrain and over the valleys. Heavy rainfall will be the primary threat with PWATs over 1" in place and slow storm motions expected. Please see the hydrology section below for more information. Dew points in the 50s will limit the strength of outflow gusts, but gusts up to 45 mph can't be ruled out. Hail, predominately under half an inch in diameter, rounds out the arsenal of thunderstorm hazards this week.

AVIATION /00Z TAFS THROUGH 00Z MONDAY/

Issued at 544 PM MDT Sat Jul 25 2026

Scattered showers and thunderstorms continue at this hour though KMTJ and KTEX look to be the only TAFs that may be affected by this convection. Gusts under and near the convection are between 30 and 40 mph so the biggest concern will be brief heavy rain possibly dropping vis for a short time. Once the sun sets, convection should come to an end though a quick shower can't be ruled out. More of the same tomorrow with another round of showers and storms expected across the region.
