KEY MESSAGES, Issued 1110 AM MST Sun Nov 8 2026

- Patchy fog may develop again tonight in prone areas such as the Cache and Heber Valleys.

- Conditions remain dry and mild areawide through a majority of the week, with the next chance for precipitation arriving next weekend.

DISCUSSION, Issued 1110 AM MST Sun Nov 8 2026

Clear skies are in place across Utah and southwest Wyoming as high pressure persists across the southwestern US. Similar to last night, isolated areas of fog may develop late tonight in the Cache and Heber Valleys, though increasing high clouds will limit surface cooling and thus likely delay or even fully inhibit fog formation.

Otherwise, expect dry conditions and another couple of degrees of warming heading into tomorrow as high pressure builds. A dry shortwave trough will swing through the region on Tuesday, producing slightly cooler temperatures on the order of a few degrees. This shortwave, depending on its strength, could help ventilate valley haze, but at this time it doesn't look like it will be strong enough to fully mix out valley inversions. High pressure will then return through at least the end of the week, with high temperatures in the low-60s across most valleys.

Model guidance continues to delay the return of active weather, with next weekend now looking more likely to remain dry and relatively warm. While there is still plenty of uncertainty with when this active weather arrives, models are in better agreement of mean troughing over the west coast by next Monday, indicative of a potential trend towards cooler, wetter (snowier) conditions.
