Blizzard Bearing Down: Iowa Issues Statewide Winter Storm Warning—Here’s What to Expect

A powerful winter storm is barreling toward Iowa just as Thanksgiving travelers hit the road, and forecasters warn it could dump 10-15 inches of snow across much of the state, with even higher totals possible north and east of Des Moines. The National Weather Service has issued Winter Storm Warnings statewide, and dozens of cities have already activated snow ordinances and parking bans to keep plow routes clear. Iowa DOT officials urge anyone planning post-holiday travel to monitor 511 road updates and consider altering itineraries. Blowing snow and wind gusts topping 35 mph may create white-out conditions Friday night through Saturday, making Interstate 35 and I-80 especially treacherous. Plow crews across the Hawkeye State are pre-treating major corridors, but they caution that intense snowfall rates—potentially 1–2 inches per hour—will quickly re-cover cleared lanes. Local governments respond • Des Moines: A 72-hour snow emergency begins Friday at 6 p.m.; vehicles left on residential streets risk tickets and towing. • Ames: The city’s red-and-white snow-route ordinance activates at 8 p.m. Friday; residents who host holiday guests are asked to move cars to driveways or municipal ramps. • Ankeny, Carlisle, Johnston, Grimes, Indianola and Osceola have each issued similar bans spanning the storm’s expected duration, some imposing fines up to $50 for violations. Northwest Iowa braced for foot-plus totals In Sioux City and surrounding Siouxland communities, meteorologists predict more than 12 inches of powder by Saturday evening, prompting early snow emergency declarations and school-event cancellations. KCAU-TV reports that eastern Siouxland could see the heaviest bands, while winds whip up dangerous drifts on rural roadways. Travel tips and safety checklist • Check tire tread, windshield-washer fluid and battery health before heading out. • Pack an emergency kit with blankets, water, high-energy snacks, a phone charger and a shovel. • Reduce speed, increase following distance and watch for snowplows; stay at least 200 feet behind. • If you become stranded, remain in the vehicle, run the engine 10 minutes each hour for heat and ensure the tailpipe stays clear of snow. What’s next? The storm’s center exits Iowa late Saturday, but light snow and blowing flakes could linger into Sunday morning. Temperatures will plunge into the teens statewide, allowing any untreated moisture to refreeze and creating black-ice hazards through Monday’s commute. Stay weather-aware by signing up for local alert texts, following National Weather Service social channels and keeping an eye on updated snowfall maps. With proactive preparation and patience, Iowans can navigate Thanksgiving weekend safely despite the state’s first major blast of winter.
