A relatively decent tornado outbreak expected with risk of a couple strong tornadoes. Matt and I left by mid-morning, aiming around the Mankato / New Ulm area. We staked at a spot on a hill just north of New Ulm, watching the situation. I was slightly concerned about the cap for the day, as weather radio was talking about relatively high CIN per ABR and other 18z soundings. However, nearly full insolation was taking place as the warm front moved northward. We decided to head a little southward to more south of New Ulm. My brother called and told us that the new Day 1 outlook had actually been upgraded to high! Woohoo! We were hearing word about a supercell that was tracking east-southeast from close to Wilmar. Needing a quick decision, we decided not to chase that supercell and to stick with our original target area, supported by NWS and SPC discussions. By mid-afternoon, a PDS Tornado Watch was issued... To make a long story short, the cap held in southern MN all day and it was a complete cap-bust. I did get a call from my girlfriend who was making me aware that the monster supercell was right in their area. Traveled all that way and the big supercell of the day crossed right near my home. Darn. The cap did break into Wisconsin and a derecho traversed the state there.
