A strong short wave trough lifting out of the Rockies combined with an atmosphere that was recovering from earlier thunderstorms.  There likely was mesoscale interactions with old outflow boundaries.  Tornadoes formed along a warm front lifting north.  Many storm spotters and chasers were unable to see the tornadoes due to the proximately to dense fog on the cold side of the front.  Those that did observe the tornadoes were astonished at the apparent width and magnitude of the tornadoes.  However, it appears that the condensation part of the tornadoes were exceptionally large due to the cold and moist airmass being entrained into them.  They appeared to be much stronger than they actually were, likely because of the amount of condensation and associated very low cloud bases.
