Des Moines, IA – Flags snap, tree branches creak, and debris skitters across streets this morning as powerful northwest winds hammer central Iowa under a High Wind Warning. Gusts near 60 mph are expected through mid-morning, making travel difficult along I-35 and I-80 and increasing the risk of scattered power outages.
According to the National Weather Service, widespread wind damage is possible as this system barrels across the region. Drivers of high-profile vehicles should use extreme caution, especially on open stretches west of Des Moines where crosswinds are strongest. Residents are urged to secure outdoor items and remain indoors if possible until winds subside.
As this system exits later today, temperatures will plummet. Highs fall into the 20s by Thursday, with the wind chill dipping below zero by Friday morning. Forecasters say the frigid air will stick around into early next week, with another round of light snow or wintry mix possible Friday and Saturday, potentially adding slick spots during the evening commute.
By late week, Arctic air from Canada will sweep into the Midwest, sending wind chills as low as -20°F across portions of central and northern Iowa. Meteorologists warn this may mark the coldest stretch of the season so far, part of a wider December cold outbreak extending across the Great Lakes and Ohio Valley.
Five-Day Outlook (Des Moines, IA):
- Thursday: Cloudy, high near 28°F, chance of light sleet.
- Friday: Flurries possible, high 24°F, low near 8°F.
- Saturday: Snow chance 40%, high 13°F, bitter cold.
- Sunday: Mostly sunny, high 18°F, wind chills below zero.
- Monday: Partly cloudy, gradual warm-up near 25°F.
