The large tornado outbreak Sunday that ripped through the upper midwest has claimed six lives and injured hundreds across five states. The Storm Prediction Center fielded hundreds of reports of tornadoes Sunday, and through filtering and cross checking have narrowed down to 82 initial tornado reports as of this morning. These numbers are preliminary (duplicates likely), and will be adjusted over the days and weeks to come. Nevertheless, this was certainly a very large tornado outbreak for November.
Here is an animated look at the core 12 hours of the severe weather outbreak yesterday as the storms initiated over Illinois and then push rapidly east at 50 to 60 mph. Tornado warnings are in red.
