Interesting Lake Effect Snow (02-08-11)


A band of lake effect snow showers moved south across the lake early in the morning on February 8, 2011 affecting portions of northeast Illinois and northwest Indiana.  With a trough of low pressure dropping southeast across northwest Indiana and a ridge of high pressure building in from the west, an area of weaker flow developed over the lake.  This allowed for several small scale circulations to develop along this band of snow, with three distinct circulations noted on radar imagery at one time.  Besides the fact that this band of snow was already intense, these smaller scale circulations allowed for more intense areas to develop over locations in northwest Indiana.  Moderate to heavy snow fell with visibilities dropping below 1 mile at times, and snow accumulating on local highways and roads.
