Iowa weather: Expect wind chills down to -45 degrees overnight
A brutal mixture of weather has set in across Iowa today.
Northwest winds continue to gust at 30-40 mph, creating blizzard conditions, and driving in colder air. On top of that, light snow showers have continued across northern Iowa through the day.

Those snow showers should steadily wind down tonight. Wind speeds will also decrease, but gusts up to 30 mph are still possible. The Blizzard Warning across northern Iowa will expire at midnight. Because of the sheer amount of snow out there, drifting will still be a problem tomorrow, but wind gusts will only be around 25 mph, not 45 mph like today.
After tonight, our main focus turns to extreme cold.
ALL BUT OFFICIAL: Monday should be coldest Iowa caucuses ever
Air temperatures will plummet into the negative teens tonight. The northwest breeze will drive wind chills all the way down to -45° at times. That sort of wind chill can cause frostbite on exposed skin in as little as 10 minutes.
The daylight hours won't be much better the next few days.
Both Sunday and Monday will be dry, but the combination of intense cold and a breeze means that it won't feel any warmer than -20°.
Temperatures will be subzero from now until Tuesday afternoon. Wind chills will be subzero until Wednesday.
Our next chance at snow is possible Thursday.
Weekend closings
Businesses, churches and many other locations are closed over the weekend due to the weather. You can see an updated list of closings here.
