Overview

A few supercell thunderstorms developed ahead of a warm front advancing into the forecast area, where they produced gusty winds, heavy rain, and hail up to 3 inches in diameter. Storms initially developed as more discrete supercells early in the evening, with the storm that went through Burlington being one of the more intense storms. Rainfall amounts reached 2 inches or more in some areas, as the anomalously moist environment favored excessive rainfall that can lead to flash flooding. Luckily, we have not received any flash flood reports, but the La Moine River near Colmar has raised to Minor Flood stage due to the recent rains.
