Crews were out treating roads, but some were still listed as partially covered with snow for the morning commute, according to the Minnesota Department of Transportation's website.

Here's a look at the roads as of 7:15 a.m. Wednesday (blue is partially covered, green is clear and purple is completely covered):

KSTP traffic reporter Josie Smith is urging drivers to slow down and give themselves an extra 5-10 minutes to get to their destination Wednesday morning.

Relief is in sight

After a string of below-zero days, temperatures will warmup starting Wednesday.

Overnight temperatures ranged from the single digits in the north to the teens and 20s in the southern part of the state. The high will be 15-25 degrees across the state, the National Weather Service says.

Scattered flurries will linger Wednesday, and more snow is likely Thursday in the southern part of the state, but mild temperatures are expected for the weekend.
