02 April 2006 - Severe Thunderstorm Outbreak

A line of severe thunderstorms developed during the afternoon across Central Missouri and quickly raced east across Eastern Missouri and into Central Illinois spawning tornadoes and bringing damaging winds in excess of 70 mph to a large portion of the St. Louis Metropolitan Area. Over 200,000 people lost power during the height of the storm.  In addition, hail ranging from pea to baseball size was observed.

Believe it or not, things could have been much worse across the area if this event would have taken place just a few weeks later. Thankfully, most of the trees had just began to bud, and there was little if any visible foilage.  If this widespread severe wind event would have occurred when the trees had leaves on them, the number of people without power would have easily been doubled.

During this event the National Weather Service in Saint Louis issued 65 warnings and received over a 160 severe weather reports.   Two fatalities have been confirmed from this severe weather event in the St. Louis County Warning Area.
