Snow forecast changes in northern Utah on Monday night as rain is expected to turn to mountain snow while a flood watch stays in effect through Monday afternoon. Chase Thomason said colder air moving into Utah could lower snow levels to roughly 7,000 to 8,000 feet late Monday into Tuesday.
The National Weather Service said the flood watch runs until 6 p.m. Monday for much of northern Utah, including the Wasatch Back, Wasatch Mountains and western Uinta Mountains. Park City is inside that watch area, and the same storm is expected to keep showers and runoff concerns active before the mountain transition takes hold.
Wasatch Mountains and western Uinta Mountains
Thomason said roughly 4 to 12 inches of snow are possible in the Wasatch Mountains through Wednesday, with 1 to 2 feet possible in portions of the Uinta Mountains. The National Weather Service forecast a different near-term path for the western Uinta Mountains, calling for 2 to 4 inches Monday night and another 3 to 5 inches on Tuesday.
That difference leaves lower and mid-mountain areas with a narrower window for accumulation than the higher ridgelines. The service said colder air should turn rain to snow above about 9,000 feet by Monday night, while snow accumulation is expected across the higher mountains through Wednesday.
Park City and
Park City sits near the edge of the rain-snow line, not in the core of the heaviest totals. The National Weather Service forecast showers Monday in Park City, followed by rain that will turn into a rain-snow mix overnight, then snow showers on Tuesday.
Little or no accumulation is currently forecast around the Park City point forecast near 8,000 feet. For residents in flood-prone areas, the practical instruction is to keep checking forecasts and be ready to act if flood warnings are issued before the watch expires.
The rainfall is tied to moisture from the remnants of Tropical Storm Rachel and a frontal boundary across northern Utah. Rebecca Brenner’s article was published on Oct. 12, 2026 at 11:12 a.m. and updated at 12:10 p.m., as the setup shifted from rain to mountain snow rather than a clean end to the storm.
The open question is how much flooding or travel disruption develops before 6 p.m. Monday, when the watch ends and the higher terrain starts carrying the heavier snow load.
