What are Iowa road conditions like?

Unlike the pre-Christmas blizzard, this snow was of the wetter variety, making whiteouts less likely, and the temperatures won't be so low as to preclude effectively treating roadways.

As of 7:15 a.m. Thursday morning, most highways in central Iowa were seasonal or partially covered. To the north and west many roads were completely covered. Tow bans are also in place for many counties along Interstate Highway 80, Insterstate Highway 35 (particularly south of Des Moines) and Highway 30 (primarily east of I-35).

Southbound Interstate 35 was briefly blocked south of Osceola by a multi-vehicle accidents around 7 p.m. Wednesday, the Iowa State Patrol reported.

"This snow will continue tonight, so please take it slow and use extra caution with any travel!" the National Weather Service's Urbandale office tweeted.

The Iowa DOT recommends checking the weather forecast and road conditions before deciding to head out on the roads and postponing trips if conditions aren't ideal.
