A spike in manic mood often accompanies terrorist activity. U.S. social mood "weather forecast" shows climax disruptive mood event(s) in the week ahead. This may include a spike in mayhem, protests, and/or terrorist activity in the news.
The climax event we were watching for was on 7/16, the shooting in Chattanooga, TN in which 5 servicemen died as well as the gunman. Chattanooga is within the high risk area highlighted by our map, but the event took place a few days outside of our time window.
