Just some added info. Dr. Mel Goldstein (who passed away in 2012?) developed a Severe Weather Index in the 1970's that was used to gauge severe weather potential in SNE. The index ranged from 1 to 5; 1 little or no severe wx potential, 5 was strong potential for tornadoes. He worked closely with region electricity suppliers to gauge the threat for power outages. In his morning update on October 3rd his index came in as 5!!! He issued updates during the day indicating the tornado potential was high, and in fact called the Office of Emergency Management several times about his concern. As a side note, I was living on the western edge of the Farmington Valley then, and observed obvious large scale low-level rotation racing northeast about 10 to 15 minutes prior to touchdown in Windsor Locks.
