Much of Iowa could receive another half-foot of snow by tomorrow morning. A Snow Advisory is posted for most of the state, north of Interstate 80. National Weather Service Meteorologist Rod Donovan says far northern Iowa will get piled on the most. He says areas around Mason City, Algona, Fort Dodge, Webster City and Waterloo could get 4 to 6 inches.
Areas from Sac City to Ames to Davenport can expect 3 to 5 inches, while Des Moines through Ottumwa should expect 1 to 3 inches of snow. Temperatures will be cold overnight with some dangerous wind chills. "The winds will remain out of the east at 10 to 15 miles an hour," Donovan says, "so that will create wind chills of 10 to 20 below zero." Iowa’s temperatures should warm up a bit on Wednesday.
Donovan expects Wednesday’s highs in the 20s or lower 30s. "But then we’ll go back into the colder weather on Thursday with another chance of accumulating snow." For the latest forecast, visit the National Weather Service’s webpage .
