Road Weather Highlights

Mountain and Far Northern Valley Road Snow (Logan Area)


Forecast Period: 5am Thursday through 5am Friday

Text Updated: 1:30am 11/21/2018

 

Active weather will develop across Utah Thanksgiving morning bringing widespread valley rain/snow and mountain snow through Thanksgiving evening.  Most showers will then retreat to the northern mtns Thursday evening/night as I-15 and the lower valleys will see very little shower activity.  Widespread mountain road snow is expected on Thanksgiving with most lower valleys running wet on Thanksgiving.  However, lower valley areas north of Ogden (including Logan) will see the threat for some slushy roads during heavier periods of snow on Thanksgiving. 

 

Motorists are advised to use caution and TravelWise. The following routes will experience weather-related travel concerns during the forecast period:

 

- Cache Valley, Logan area

- I-15, North of Tremonton  

- I-80, Parleys Canyon to Wyoming

- US-89, From Brigham City over Sardine summit through Logan and over Logan Summit

- I-70, Clear Creek Summit near the I-15/I-70 Junction; Ivie Creek Summit east of Saina

- US-40, I-80 Jct through Strawberry Reservoir

- US-191, North of Vernal; Indian Canyon Summit (south of Duchesne)

- US-6, Soldier Summit (between Spanish Fork and Price)

- SR-190, Big Cottonwood Canyon east of Salt Lake Valley

- SR-210, Little Cottonwood Canyon east of Salt Lake Valley

 

**See the travel weather highlights graphic below, which is valid 5am Thanksgiving through 5am Friday.**

 

***An active weather pattern is then expected to continue through much of the holiday weekend as a cold front is expected to move south through the state Friday night/Saturday.  This will bring road snow levels down to most valley floors north of Cedar City.***
