Jefferson City, Missouri – Spring 2026 could warm up faster than usual across Missouri, with above normal temperatures increasing the likelihood of early-season heat before summer officially begins.
According to NOAA’s Seasonal Temperature Outlook released February 19, Missouri falls within a broad zone favored for above normal temperatures during March-April-May 2026. While the strongest warmth signals are positioned farther south, the state still leans milder than average overall this spring.
In St. Louis and eastern Missouri, that could translate into more frequent 70-degree afternoons in March and a quicker climb into the 80s by late April and May. Passing cold fronts will still bring occasional cool-downs, but sustained chilly stretches appear less likely under the seasonal signal.
Kansas City and western Missouri may also see extended mild periods between storm systems tracking through the Plains. Warmer soil temperatures could accelerate early planting schedules across central counties, including Columbia and Jefferson City.
Southern Missouri, including Springfield and the Ozarks, is likely to experience repeated warm spells that push temperatures above seasonal norms, especially during late April and May. That setup may also drive pollen levels higher earlier in the season.
Overall, Missouri appears poised for a faster-building spring marked by frequent mild to warm afternoons. Residents should prepare for earlier air-conditioning use, rising pollen counts and the potential for early heat spikes as the season progresses toward May.
