Road Weather Highlights

Heavy Mountain Road Snow and Friday AM Commute Road Snow


 

Forecast Period: Through 5PM Friday

Text Updated: 1AM 1/18/2019

 

A strong winter storm is now impacting the state of Utah and will persist through Friday morning. This system is currently bringing widespread valley rain and heavy mountain snow. This looks to persist through much of the evening. Additionally there is a threat for a flash of lightning and rumble of thunder across northern Utah this evening, bringing with it the potential of heavy rainfall/snow and sleet. Snow levels will initially be quite high for the rest of the day Thursday, generally above 6500-7000 feet (from north to south across the state), but will slowly drop as a cold front makes its way across Utah Thursday evening/night. This front will transition valley areas along I-15 north of Cedar City from rain to snow around or after midnight Thursday night. I-15/Valley routes will generally see light road snow late Thursday night through early Friday morning. Significant road snow accumulations are expected for all mountain routes across the state. There may be periods of road snow Friday morning during the commute along much of the Wasatch Front. For a route specific forecast please refer to the routes specific alert. 

 

Motorists are advised to use caution and TravelWise. Motorists heading up canyon and mountain routes should be prepared for chain restrictions at any time during snow events.  The following routes will experience weather-related travel concerns during the forecast period:
