Des Moines, IA – Iowa will face a sharp and dangerous cold push as an Arctic Blast grips the Upper Midwest from Monday, Dec. 1 through Friday, Dec. 5, launching the state into a harsh Cold December pattern characterized by subzero wind chills, single-digit temperatures, and periodic snow showers.
According to the National Weather Service, early-week disturbances interacting with incoming Arctic air will bring light snow and flurries statewide. While accumulations are expected to stay minor, forecasters warn that reduced visibility, quick bursts of snow, and freezing temperatures could create slippery roads during the morning and evening commutes.
Temperatures will fall into the single digits during the coldest nights, with below-zero readings possible across northern Iowa. Wind chills may plunge between –10°F and –25°F, especially late Monday night through Thursday morning, posing risks for exposed skin and unprotected livestock.
NOAA’s 6–10 Day Temperature Outlook places Iowa deep inside the below-normal temperature zone for Dec. 1–5, reflecting one of the strongest cold anomalies in the central U.S. Persistent northwest winds will keep light snow opportunities in the forecast, particularly across northern Iowa where stronger cold advection will be present.
While no major winter storm is currently expected, forecasters caution that the combination of subzero wind chills, icy roads, and scattered snow showers may create hazardous travel conditions throughout the week.
Residents should plan for prolonged bitter cold and monitor updated NWS alerts as conditions evolve.
