The corresponding 1-minue GOES-16 “Clean” Infrared Window (10.3 \u00b5m<\/strong><\/a>) images below helped to highlight areas of mesoscale banding where precipitation rates were enhanced (some sites reported snowfall rates of 1 to 2 inches per hour).<\/p>\n

Microwave estimates of snowfall rate (SFR) are available at this website<\/a>, and imagery during the day on the 25th are shown below. The heavy band of snow is apparent early in the morning of 25 March; by afternoon, it has shifted eastward to hug the Lake Michigan shoreline in Wisconsin.<\/p>\n\n\n\n
