Figure 1 depicts the surface observations at 2:00 am EDT, which shows a cold front moving across Ontario and Quebec and a cold front moving across the U.S. Midwest. The cold front over ON/QC likely became near-stationary as the Midwest cold front moved east-southeast. This cold front eventually moved toward Massachusetts, which ultimately led to this tornado.
