Weak storm systems are expected to bring light rain to northern Utah valleys and snow to the mountains on Monday night and Tuesday night. A more significant storm system is forecasted to arrive late in the week, bringing widespread precipitation and an increased risk of flash flooding.
A shallow cold front is expected to move into northern Utah late Monday night. This front is anticipated to bring a quick round of showers, though high-resolution models suggest lighter precipitation than global models. Forecasted accumulations include 0.15 to 0.3 inches in the Bear River Range, with less than 0.1 inches expected in adjacent valleys and no measurable precipitation south of Ogden. Snow levels could fall as low as 6,500 feet near the Idaho border, potentially resulting in light snow accumulations in higher terrain.
Temperatures are expected to trend warmer on Monday, reaching near or slightly above normal levels in northern Utah while remaining below normal in the south. Following the cold front, Tuesday is expected to bring cooler temperatures, with northern Utah trending back toward slightly below normal. While precipitation from the Monday night front may clear by sunrise, a second, weakening trough is expected to eject across northern Utah on Tuesday night, bringing another potential round of light precipitation.
The weather pattern remains active as a strengthening storm system over the Pacific Northwest and a second system from the west interact. While there is model uncertainty regarding the exact timing of the weekend precipitation, Sunday is currently identified as the wettest day. The storm system is expected to impact the area through the weekend and potentially into early next week.
