It'll be t-shirt weather on Monday in Salt Lake City, with highs near 70, but don't pack away the parkas yet. Believe it or not, the National Weather Service has issued a winter storm watch for Tuesday afternoon through Thursday morning.
According to the NWS, a “cold, late-season winter storm will bring accumulating snow to much of northern and central Utah” on Tuesday, with snow levels falling to the valley floors.
How much snow? The NWS warns local residents to expect up to 3 inches on the valley floors; 4-9 inches along the benches; and 1-2 feet in the mountains.
