Thursday was a difficult day for travel in western Iowa, with snow- and ice-covered highways leading to several crashes.
Black ice led the Iowa State Patrol to warn motorists to slow down and drive cautiously.
The National Weather Service predicted between 2 and 4 inches of snow in Iowa between Thursday night and today. Northwest Iowa could get the heaviest amounts, and patchy freezing drizzle is expected in southern Iowa.
Authorities restricted towing along Interstate 29 from Missouri Valley to Sioux City Thursday because of repeated single-vehicle crashes and icy roads.
Also, troopers worked several crashes on Interstate 80 between Minden and Avoca. Drivers were caught off-guard and their vehicles went out of control at high speeds.
Among the crashes were two on I-80 that caused minor injuries:
— Two New Mexico residents were taken to a Harlan hospital after crashing near Shelby about 10:20 a.m.
— About an hour later, a McCook, Neb., woman was driving westbound near Walnut when she lost control and crashed her vehicle.

A major snowstorm last week dumped more than a foot of snow in some parts of Iowa. Low temperatures with frigid wind chills have persisted since then.
It's unclear what kind of impact a few inches of snow will have on recovery efforts.
Weather officials said cool and dry conditions are expected for Saturday.
