Interesting Lake Snow Band

Issued 450 pm CST Wed Jan 14 2009

Lake effect snow bands are common on Lake Michigan, though they tend to favor the Michigan and Indiana shores due to prevailing northwest winds during most cold episodes that favor their development.  Occasionally, they develop circulations or "mesovortex" which are likely mini-low pressure systems.  One of those brushed the shore on Racine/Kenosha counties this morning...bringing a burst of snow.  Some example images of the event are below, which run from 8 am to Noon Wed Jan 14 2009.
