A Midweek Return to Winter

Hello everyone! My name is Christine Kruse and I am a meteorologist with the National Weather Service in Salt Lake City. Today we have created a short briefing with information on a winter storm to impact Utah Wednesday into Thursday. This briefing was created on Tuesday December 19 and should not be used after Wednesday December 20. What are the main impacts across Utah with this midweek winter storm? Expect significant travel impacts along I-15 from Nephi to Cedar City Wednesday afternoon into Thursday. Accumulating snow is expected for the Wasatch Front during the Wednesday PM commute. There is also the potential for accumulating snow in Utah’s Dixie. Currently, snow totals are expected to remain below one half an inch in the St. George area, with up to 2 inches across higher elevations of Washington County. Finally, expect gusty winds up to 50 mph across portions of western Utah ahead of the front. When will the storm begin for different portions of the state? For northern Utah, the cold front and associated snow will begin Wednesday afternoon and end late Thursday morning. For central Utah, expect the front and precipitation to arrive Wednesday evening and continue into Thursday evening. For southwestern Utah, expect the cold front and precipitation to arrive Wednesday evening and continue into Thursday night. For southeastern Utah, expect arrival Wednesday night, continuing into Thursday night. Probably the biggest question is…how much snow can be expected? Through Thursday, expect 1 to 3 inches along the Wasatch Front, 5 to 10 inches for the Wasatch Mountains, 2 to 4 inches for the western Uinta Basin, 6 to 12 inches for the central and southern Utah mountains, 4 to 8 inches with locally higher amounts for the southwest Utah valleys above 4500 feet and finally 1 to 3 inches for the southern Utah valleys. To summarize, a winter storm will impact Utah Wednesday into Thursday. The cold front will cross the state Wednesday morning into Wednesday night. The heaviest valley accumulations are expected along the I-15 corridor from Nephi to Cedar City with significant travel impacts along I-15 Wednesday night into Thursday. Snow levels will fall to valley floors statewide including Utah’s Dixie and the Lake Powell area. Currently, accumulations are most uncertain for the lowest elevations in southern Utah. The Wednesday evening commute may be impacted along the Wasatch Front. Strong winds are expected across mountains and western valleys ahead of the front. Thanks for watching!
