I was trying to find out why we had an outbreak 3 days in a row. why did the system produce three consecutive outbreaks? Did the system get blocked, was it moving very slowly, what happened?
 
As the main trough dug in from the west, the low became a "cut-off" low, tearing away from the main branch of the jetstream. With extremely strong speed maxes wrapping around the low consecutive days (up to 80/90kst in some areas), outbreaks of supercells and tornadoes occurred, and largely in the same areas, because the origin of the energy (cut-off low) didn't move.

In a typical scenario, the same thing happnes except the trough stays with the jet, does its thing, and then kicks back out with the main jet....however last weekend, we had what I call a "pinwheel" powder keg, where the energy separated itself and just wrecked the same areas all weekend.

I'm sure someone with schooling can better explain all this.
