KEY MESSAGES, Issued 1131 AM MST Wed Nov 4 2026

- A weak system traverses the Great Basin today, bringing light valley rain and high elevation snowfall to northern and central Utah.

- A second weak storm system may graze northern Utah on Friday before high pressure builds for the weekend, keeping temperatures around 5 degrees below normal.

DISCUSSION, Issued 1131 AM MST Wed Nov 4 2026

Morning satellite imagery reveals an apparent circulation shifting across Utah, associated with a mid-level closed low that brought scattered light showers to the area. As this low continues to track eastward, these showers will do the same, largely ending by midnight tonight. Low-level clouds are likely to linger into the morning hours across much of the area, potentially inhibiting fog potential even for fog-prone locations such as the Cache Valley.

A weak shortwave trough moving through the area late Thursday night/early Friday morning is trending stronger with recent model runs, though moisture will be very limited, even moreso than today. Still, isolated showers may develop across far northeastern Utah/southwest Wyoming Thursday night; sometimes, a vort max will provide enough lift to produce showers despite this lack of moisture. Increased cloud cover, alongside slightly better mixing, may once again inhibit valley fog development early Friday morning, something that looked more likely in prior forecasts. Finally, this wave will also act to keep temperatures around 5 degrees below normal through Friday.

High pressure will build heading into the weekend, resulting in a steady warming trend that will bring temperatures closer to 5-10 degrees above normal by early next week. Forecast confidence is low in our next precipitation chances; model guidance suggests a return as early as next Thursday, but likely not until Friday or later.
