Tomorrow should be just fine. Snow not predicted until late this week. And even if it snows, I-15 between SLC and Provo is the first thing they plow, and keep salted and clear. The roads are clear and dry and will be all week.
It’s been a few days since it snowed… the roads are just fine right this second. Unless you are driving early morning or late night and/or while snow is falling you will be fine.
if you drive the speed limit and pay attention you’ll be fine.
if you plan on driving up any canyons that is a different story, my advice there would be to just drive extremely carefully, and don’t slam on your breaks while turning.
Main roads on the Wastach Front perfectly cleared and fine. Still some bits of hard packed snow in the residential roads but drivers should be slow on those streets anyway.
