Des Moines, Iowa – A warmer-than-normal and wetter weather pattern is expected to develop across Iowa heading into Valentine’s Day weekend, increasing the likelihood of rain, wet snow, and slushy travel conditions from Saturday through midweek. While no single high-impact winter storm is currently indicated, repeated rounds of precipitation could create cumulative impacts on roads, rivers, and daily travel statewide.
According to the National Weather Service Climate Prediction Center, Iowa is favored for above-normal precipitation and above-normal temperatures during the February 14–18 period. This setup limits prolonged Arctic cold while shifting precipitation toward rain or mixed events, especially across southern and central Iowa.
In central Iowa, including Des Moines, Ames, and Ankeny, milder daytime temperatures may allow precipitation to fall mainly as rain. Overnight cooling could still produce periods of wet snow or slush, increasing the risk for slick spots during early morning travel along I-35, I-80, and I-235.
Eastern Iowa communities such as Cedar Rapids, Iowa City, and Dubuque may see fluctuating precipitation types as temperatures hover near freezing at night. Slushy road conditions are possible on I-380 and Highway 20, particularly during overnight and early morning hours.
Across western Iowa, including Council Bluffs, Sioux City, and Carroll, rain is expected to be the dominant precipitation type. Repeated rainfall could lead to ponding on roadways and rising water levels in smaller streams, especially where frozen or saturated ground limits drainage.
In northern Iowa, including Mason City and Decorah, colder overnight temperatures may allow more wet snow to mix in at times. Heavier, moisture-laden snowfall during colder windows could create brief travel slowdowns on rural highways and county roads.
The Iowa Department of Transportation advises motorists to use caution during overnight travel periods as temperatures fluctuate and precipitation types change. Air travel through Des Moines International Airport and regional airports may see occasional delays tied to low ceilings or steadier precipitation, though widespread disruptions are not expected.
This warmer, wetter pattern is expected to persist into midweek. Additional advisories may be issued as individual systems become clearer, and residents are urged to stay alert for updated alerts, particularly during overnight and early morning travel windows.
