About Tornadoes in McKinney
This overview was written August 10, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.
Severe weather season reaches McKinney early, usually stirring by March and building through April and May, when warm, humid air drawn north from the Gulf of Mexico rides over the Blackland Prairie and meets cooler, drier air pushed east along the dryline and spring cold fronts. That collision, energized by strong jet-stream winds aloft, gives thunderstorms across Collin County the wind shear they need to rotate. Autumn brings a quieter reprise: the same ingredients occasionally reassemble in October and December, so the season here has a long tail.
The record compiled by the NOAA Storm Prediction Center stretches across generations of McKinney households.
