Des Moines, IA – A spring-like shift in the weather pattern is expected to impact Iowa during the February 11–17 period, bringing above-normal temperatures with potential statewide implications.
According to the NOAA Climate Prediction Center, the 8–14 day outlook strongly favors warmer-than-normal temperatures across the Upper Midwest, including all of Iowa. This transition follows recent winter cold and signals a temporary break from prolonged mid-winter conditions.
In central Iowa, including Des Moines and surrounding communities, average mid-February high temperatures typically range from the upper 20s to low 30s. Forecast guidance suggests daytime highs may frequently climb into the 30s and low 40s during this period. Overnight lows are also expected to moderate, reducing the frequency of subzero temperatures.
Eastern Iowa, including Cedar Rapids, Iowa City, and Davenport, is forecast to trend several degrees above normal, with more consistent afternoon warming. Western Iowa, including Sioux City, Council Bluffs, and Carroll, may also experience milder daytime temperatures, though cooler nights will persist.
As temperatures rise, existing snowpack across much of the state is expected to begin melting. Snowmelt combined with rainfall could increase runoff into rivers, streams, and storm drainage systems. Transportation corridors such as I-35, I-80, I-380, I-29, and US-20 are particularly sensitive to ponding and localized flooding during rapid warmups.
The Climate Prediction Center’s precipitation outlook indicates near to above-normal precipitation potential during this timeframe. While no specific storm systems are identified, rainfall combined with melting snow could contribute to rises on rivers including the Des Moines, Cedar, Iowa, Skunk, Missouri, and Mississippi.
Warming temperatures may also weaken ice on ponds, lakes, and rivers statewide, creating hazardous conditions for recreation. The National Weather Service advises residents to avoid frozen waterways as ice conditions deteriorate during thaw periods.
Commuters, students, and outdoor workers may notice more spring-like afternoons, but officials caution that winter hazards can persist overnight and in shaded or low-lying areas.
Residents across Iowa are encouraged to monitor updated forecasts, river statements, and local advisories as confidence increases closer to the February 11–17 timeframe.
