Text Updated: Thursday 3/30/2017 at 1:00 A.M.
A cold front will begin pushing its way into the western half of Utah Thursday afternoon. The cold front will reach the Wasatch Front around 6 PM while simultaneously surging southward, allowing for relatively warmer conditions to remain over areas north from Ogden northward. This front will bring increased mountain snow showers to central and southern Utah and also allow valley rain to mix with and switch over to all snow for Thursday night. The biggest road slush impacts Thursday night are expected from Santaquin to Cedar City along the I-15 corridor and along western desert routes. However, there will be an increased threat for road snow along higher portions of the I-15 corridor between Cove Fork and Parowan. Precipitation then continues through Friday morning and into the day Friday. Valley roads are expected to trend back towards wet by 10 AM Friday, with road snow concerns lingering through Friday afternoon along mountain routes.
Strong NW winds will also impact travel along the western third of Utah, beginning after noon on Thursday. Strongest gusts are expected across NW Utah and portions of I-80, with strong gusts lasting through Friday afternoon.

- I-15, Santaquin to Ceder City
