A two-day storm system will bring colder temperatures and widespread snow to many parts of the state starting Wednesday night. To start, northern Utah valley rain and mountain snow will move in overnight with many valleys seeing a changeover to snow in the early morning hours of Thursday. Main road impacts will remain across mountains and throughout canyons.

Across Northern Utah, Cache valley and bench routes likely see some light road snow/slush but lower valleys and I-15 will mostly run just wet early Thursday morning.  

Many mountain routes will see road snow overnight through Thursday morning with greatest impacts across northern Utah, particularly over Logan summit (US-89), Sardine summit (US-89) and Parleys summit (I-80). 

Throughout Thursday morning, snow will move into southwest Utah and bring the concern for light road snow across higher parts of I-15 as well all adjacent canyons/mountains. By midday Thursday, all but the highest summit routes will be able to run wet under continuing snow showers

 

An updated Road Weather Alert will be issued tomorrow to cover Thursday night through Friday impacts.
