Winter Storm on January 21

A couple of weather systems affected southern Indiana and central Kentucky Tuesday morning.  One was a surface low pressure that was deepening just southeast of our area and another was a potent upper level disturbance dropping down across the Midwest.  The combination of the two brought a patchwork quilt of snows in multiple rounds from late Monday night through Tuesday morning.  Snowfall totals from this event, based on reports received by the National Weather Service, are depicted below.


A secondary cold front, associated with the upper level feature mentioned above, blasted through the Louisville metro around 8 AM, blowing the snow and briefly creating near whiteout conditions over parts of the region.  The two images below were taken 10 minutes apart near Canterbrook Farms in southeast Jefferson county Kentucky, with the first being at 8 AM.  Notice the snow in the trees.  The winds associated with the frontal passage gusted at 30-40 mph.  These winds blew a lot of the snow that had accumulated on trees and power lines off, as depicted in the second photo below.  The radar image below that indicates what our radar showed as this arctic front passed near that location.
