Several inches of snow have fallen and some areas are reporting a wintry mix as a storm moves through Iowa. A Winter Storm Warning is in effect through Saturday.


"We've seen several inches of snow so far this evening and now mixed precipitation is falling in many areas," said First Alert Storm Team Meteorologist Justin Gehrts. "Precipitation will continue through the night ending by early Saturday morning."


Two to four inches of snow is expected to fall in areas south of Highway 20. Areas north of Highway 20 could see four to seven inches of snow.


"Sleet and freezing drizzle will continue mainly south of Highway 20," Gehrts warned. "This will lead to a glaze of ice on top of already slick roads."

The combination of ice and windy conditions could lead to isolated power outages, similar to the system that moved through last weekend.


Winds will pick up, especially on Saturday as the storm moves out. Wind gusts over 40 m.p.h., from the northwest, will cause blowing and drifting snow. This is of greater concern north of Highway 20, especially in rural areas.


Following this system, temperatures will plummet during the daytime hours Saturday.

"We'll probably have a 20-degree drop during the day Saturday," Gehrts said. "We will have single-digit highs Sunday and Monday, with below-zero lows. Bitterly cold wind chills, colder than 20 below zero, are possible Saturday night through Monday morning.
