Salt Lake City, UT – Light rain patters across windshields this morning as Utah wakes under gray December skies. The storm system sweeping through northern Utah is expected to bring steady rain through midday, with a changeover to snow possible in higher elevations by Sunday morning, making for slippery travel along I-80 and mountain passes.
According to the National Weather Service in Salt Lake City, rain will taper gradually this afternoon as clouds begin to thin. Temperatures hover near 40°F, but cold air arriving from the northwest could drop lows to the upper 20s by Sunday morning, allowing any wet pavement to freeze into slick patches — especially in shaded valley roads and elevated bridges.
Sunday will bring a welcome break in the clouds. Mostly sunny skies return by late morning, with highs climbing into the mid-40s. But early commuters should use caution; patchy black ice is possible after the overnight cooling. By Monday, mild air returns with highs near 49°F before another midweek rain chance develops late Tuesday into Wednesday.
Travelers heading through canyons or preparing for holiday drives should keep winter gear handy and plan extra time. Conditions will vary sharply between valleys and passes — clear in the city, but slushy and freezing in the mountains.
