this evening.

Roadways will become or continue to be icy and snow packed. Periods of near whiteout conditions in heavy snowfall and some blowing snow will be possible especially on higher terrain. Check the latest road reports and avoid travel especially this morning if possible.

Winter storm warning remains in effect until noon MST today.

Snow will decrease in the valleys of eastern Utah and northwest Colorado by mid-morning, and along the I-70 corridor and the valleys of southwest Colorado by midday. Snow will continue over most mountain ranges, however, until this evening.

Very cold temperatures in the single digits to below zero will occur tonight.
