DES MOINES, Iowa -- Much of Iowa could see strong to severe thunderstorms to end the work week.
"We're looking at the possibility of strong winds, large hail, and possibly a few tornados as well," says National Weather Service Meteorologist Jeff Zogg.
He says the storms late Friday afternoon into Friday evening will follow a familiar weather pattern we've seen this summer.
"We get a period of some warm and humid conditions, relatively dry--then what happens is a disturbance from the west moves in and brings a front into the area, and that sets off the chances for showers and thunderstorms," Zogg says.
He says it looks like the storm system could move across much of the state by late Friday night.
"The best threat for severe weather on Friday will be Friday afternoon into the evening. The way it's looking right now is the thunderstorm activity would develop from the west or northwest and progress southwest across the state," Zogg says.
Right now Des Moines, Ames and Cedar Rapids are under a slight risk for severe weather, while Iowa City, the Quad Cities and Dubuque are under a marginal risk.
