Des Moines, Iowa – Slick stretches could develop on I-80, I-35 and I-235 before 8 a.m. Thursday as light overnight snow brushes central and northern Iowa, but temperatures climbing 15 to 20 degrees above seasonal averages will melt most accumulation before the late-morning commute.
According to the National Weather Service Climate Prediction Center, Iowa sits in a 50 to 60 percent above-normal precipitation zone through Tuesday. That stronger signal spans much of the Midwest and central Plains, increasing the likelihood of multiple systems tracking across the state as February winds down.
In Des Moines, where average highs this time of year sit in the mid-30s, afternoon readings next week may climb into the upper 40s and low 50s. Cedar Rapids and Waterloo could see brief bursts of overnight snow or a rain-snow mix before daytime melting takes over. Along I-29 in western Iowa, including Sioux City and Council Bluffs, early slush may give way to steady rain as milder air pushes north. Farther north toward Mason City, light accumulation may linger slightly longer before temperatures rebound above freezing.
The broader outlook favors above-normal warmth stretching from the Gulf Coast into the Midwest and parts of the Northeast, while colder air lingers across the northern Plains and portions of the West. That contrast keeps the jet stream active over the region, supporting repeated rounds of precipitation.
Drivers should allow extra travel time during early morning hours, clear storm drains to reduce ponding and monitor Iowa DOT updates for changing road conditions. The milder pattern continues into early next week, though additional advisories could follow if stronger systems develop. Winter is weakening across Iowa, but it has not fully stepped aside.
