January 21-22, 2005 Snowfall
snowfall amounts       snowfall plot

Brief Synopsis

A surface low pressure area strengthened over the plains Friday afternoon and moved rapidly across the Mississippi Valley and Indiana Friday night...reaching Ohio Saturday morning and eventually the East Coast by Saturday Night. Moisture flowing north ahead of and around the northern perimeter of the low (which had become more of an inverted trough of low pressure) combined with cold air in place across the Great Lakes region to produce widespread snowfall. Surface high pressure from Canada pushed into the north central states Friday night and early Saturday in the wake of the departing low. The tight pressure gradient between the high and low pressure generated strong winds that gusted to around 40 mph at times. This caused considerable blowing and drifting snow on Saturday with significantly reduced visibilities.

Northeast winds along Lake Michigan added and additional 2 to 4 inches of snow to the the lakeside counties due to lake effect snow showers.
