A mid/upper level low passed by just to the southeast of the forecast area on March 11th with a deformation band forming across our region. Colder air began to funnel into the area during the afternoon hours changing the rain to snow rather quickly from northwest to southeast. This was a difficult event to forecast for due to the warm ground and air temperatures at or above freezing. Thus, the snow had a hard time sticking in places that it didn’t come down hard enough. This was especially true for the Jackson Purchase area of western Kentucky from the Mississippi River to the Lakes Region. Amounts of 2 to 4 inches were common across southeast Illinois into northwest Kentucky and southwest Indiana. There was even a narrow area of 4 to 6 inches.
