Extreme Cold: Arctic Air Moves Into State

15 Car Pile Up

After a very snowy Monday, today will be a breeze, literally. Winds today will be gusting up to 20mph which will cause some of that very light fluffy snow to be blown around. Snowfall accumulations ranged from 1″ to as much as 7″ Monday. Snow began to fall across western Iowa around 10am and then moved into the Des Moines metro by the noon hour. The heaviest snowfall then began around the 3 o’clock hour which then turned the evening commute into a nightmare. Drive times that should have taken 15 minutes, turned into a hour or more. A 15 car pile up occurred around 4pm in Altoona, Iowa. Iowa Storm Chasing Network’s Brennan Jontz was on the scene of the accident and captured the photo above. Fortunately the snow is done for a few days, with only a slight chance across northeast Iowa at the end of the week.


An arctic air mass is moving in behind the snow we received on Monday night, bringing frigid temperatures and strong winds to the state. We are expecting windy and cold conditions, especially as we move through the middle part of your week. Winds will be out of the northwest at 10 to 20 mph, with gusts as high as 25 mph. The winds will make it feel even colder. Wind chill values will be dangerously cold, possibly reaching as low as -25 to -30 degrees. Blowing snow could still be a hazard as we move through Tuesday and Wednesday.

Iowa Highs Wednesday

We are expecting sub-zero temperatures Wednesday, with a high around -6 in Northern Iowa. It will be a couple degrees warmer, with lows around -3 in the southern part of the state. The strong northwesterly winds during the day will make it feel even colder. Lows Wednesday night will be around -13. With the combination of bitterly cold temperatures and gusty winds, these are conditions you will want to stay out of if possible.
