Detroit, Michigan – A stronger spring signal is emerging across Michigan heading into early March, with confidence increasing that both temperatures and precipitation trend above seasonal averages during the Feb. 28 through Mar. 13 period.
According to the National Weather Service Climate Prediction Center, Michigan carries a 50% to 60% probability of above-normal temperatures in the Week 3-4 outlook. At the same time, precipitation probabilities also rise into the 50% to 60% range, pointing to a wetter-than-average pattern across much of the state.
The warmer and wetter signal spans the Interstate 94 corridor from Detroit to Kalamazoo, north along Interstate 75 through Flint and Saginaw toward the Straits, and west along Interstate 96 into Grand Rapids and Muskegon. This broader atmospheric setup favors fewer prolonged Arctic intrusions compared to typical late-February standards.
The elevated precipitation outlook suggests a more active storm track across the Great Lakes region. While the long-range guidance does not specify exact storm timing or precipitation type, it does indicate a higher probability of systems affecting both Lower and Upper Michigan during the two-week window.
Major population centers including Detroit, Lansing, Grand Rapids, Traverse City and Marquette fall within both the warmer and wetter zones. The Week 3-4 outlook reflects large-scale atmospheric trends rather than specific day-to-day conditions.
Additional refinements are expected as the late-February to mid-March timeframe approaches and shorter-range guidance provides greater clarity on individual systems.
