Des Moines, Iowa – A prolonged stretch of below-normal temperatures will continue across Iowa this week, with multiple nights of subzero lows, especially across northern Iowa, according to the National Weather Service.
The National Weather Service in Des Moines reports that temperatures will remain below seasonal averages through late January, with the coldest conditions concentrated in the northern half of the state. Overnight lows are expected to dip below zero several times this week, while daytime highs struggle to climb out of the single digits and teens.
Forecast highs across central Iowa are expected to range from the upper single digits to the low 20s, with overnight lows generally between 2 degrees above zero and 12 below, depending on location and cloud cover. Northern Iowa may see the coldest readings, particularly during clear overnight periods.
Despite the persistent cold, forecasters say little to no precipitation is expected, keeping conditions dry but allowing cold air to remain firmly in place. The lack of snowfall may reduce new travel hazards, but officials caution that existing icy patches and refreeze risks remain during overnight and early-morning hours.
The extended cold may increase risks of frozen pipes, vehicle issues, and cold-related illnesses, especially for those spending extended time outdoors. These conditions may be especially impactful for early-morning commuters, farmers, outdoor workers, and students.
Residents are advised to dress in layers, limit prolonged outdoor exposure, ensure vehicles are winter-ready, and protect pipes as the cold pattern continues through the week.
Forecasters note that temperatures are expected to gradually moderate beyond the weekend, but cold conditions will remain the dominant weather story through the end of January.
