Overview
|
Several inches of snow fell across much of the region beginning Tuesday, February 21, 2023 and ending Thursday, February 23, 2023. Highest accumulations from the two day storm were observed north of the I-90 corridor with several locations topping out over 1 foot. The combination of the heavy snow fall and a wintry mix of sleet and freezing rain disrupted travel across the region. Ice accumulations around 1/4 of an inch were observed along the far southern edge of the forecast area from southern Fayette (IA), Clayton (IA), and Grant (WI). |
