St. Louis, Missouri – A colder push of air settling into the Midwest ahead of St. Patrick’s Day could turn part of Missouri’s active storm track into accumulating snow, particularly across northern counties between March 11 and March 17.
According to the National Weather Service Climate Prediction Center, northern Missouri trends near to below normal on temperatures during the 8-14 day period, while much of the state carries a 40-50% probability of above-normal precipitation. That overlap increases the likelihood that stronger systems produce measurable snow instead of cold rain, especially during overnight and early morning hours.
In Kansas City, Columbia and Kirksville, nighttime lows dipping into the upper 20s and lower 30s could support slushy accumulation on grassy surfaces and untreated roads if moderate precipitation develops. Along the U.S. 36 corridor and north of Interstate 70, surface temperatures may remain cold enough for steadier snowfall. In St. Louis and Springfield, rain is more likely during the day, but brief rain-to-snow transitions remain possible if colder air deepens at night.
The broader eastern United States is favored to see wetter-than-normal conditions, while California and much of the Southwest trend drier, sharpening the west-to-east contrast in the national pattern.
Missourians should monitor early morning road conditions, especially on bridges and overpasses where pavement cools fastest. Even light late-season snow can create slick travel. Additional updates are expected as the March 11-17 window approaches and storm timing becomes clearer.
