St. Louis, Missouri – A warmer-than-normal and wetter weather pattern is expected to take hold across Missouri heading into Valentine’s Day weekend, increasing the likelihood of rain, wet snow, and slower travel from Saturday through midweek. While no single major winter storm is currently signaled, repeated rounds of precipitation could create cumulative impacts on roads, rivers, and daily travel statewide.
According to the National Weather Service Climate Prediction Center, Missouri 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 central and southern portions of the state.
In eastern Missouri, including St. Louis, St. Charles, and the Metro East region, milder daytime temperatures are expected to keep much of the precipitation as rain. Overnight cooling could still allow periods of wet snow or slush, increasing the risk for slick spots during early morning travel along I-70, I-64, and I-55.
Across western Missouri, including Kansas City, Independence, and Lee’s Summit, repeated rainfall may slow travel along I-70 and I-435, particularly during heavier showers. Brief rain-snow mix remains possible overnight, though confidence remains low for meaningful snow accumulation.
Central Missouri communities such as Columbia, Jefferson City, and Sedalia may see fluctuating precipitation types as temperatures hover near freezing at night. Slushy road conditions are possible during overnight and early morning hours, especially on bridges and untreated secondary roads.
Southern Missouri, including Springfield, Joplin, and the Ozarks, is expected to see rain as the dominant precipitation type. Persistent rainfall could increase runoff into creeks and rivers, prompting closer monitoring in flood-prone areas.
The Missouri Department of Transportation advises motorists to use caution during overnight travel windows as temperatures fluctuate and precipitation types change. Air travel through St. Louis Lambert International Airport and Kansas City International Airport 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 periods.
