Wind Gusts on January 12th

A very intense low pressure system moved through the northern plains and into the Mississippi River valley during the day Monday, January 12th, 2009.  On the back side of the low pressure system, strong northwest winds developed, ranging from 30 to 40 mph sustained, with wind gusts from 41 to 58 mph.  Due to some light snow that had previously fallen across the area, the strong winds created near whiteout conditions at times across parts of the region.  Below is a map that displays the peak wind gust recorded across eastern Nebraska and western Iowa on January 12th, 2009.  Snowfall amounts from 1/2  to 3 inches had fallen preceding the winds which helped to create significant areas of reduced visibility as low as one quarter mile at times.
