Chasers Ryan Pfannkuch, Adam Nunnikhoven, and I left Ames around 11:30am and headed for a preliminary chase target of Ottumwa, Iowa. We stopped at a hotel on the north side of the city around 1:30pm for wireless and by 3pm noticed the arc of convection beginning to form south of Omaha towards Kirksville, MO.
The first tornado warnings in our chase area began occurring around this time one county south of Des Moines, where small rotating storms began to form right on the low. However, we played the higher instability to the south and east and it ended up paying off. A tornado warned storm, part of a broken line, crossed into Davis county Iowa at around 3:30pm.
We set up our position on HWY 2, roughly 5 miles SE of Bloomfield, IA and we noticed a rain free base with a lowering quickly approaching from the SW. After only about 10 minutes we were amazed to see a cone funnel cloud extend halfway to the ground two or three miles away from us and then learned law enforcement reported a brief touchdown in this area around 3:46pm. We watched the cone funnel dissipate and then were forced to continue east on HWY 2 due to the precip core blocking our view. The decision to move east was a good one as a new funnel formed over HWY 2. We had trouble viewing it however because we were battling RFD winds of 60-70 miles per hour that was battering the chase vehicle.
This problem somewhat subsided however once we reached a north route, county road V42. We traveled north through the town of Pulaski with the funnel clearly visible to our west. It extended closer and closer to the ground as each minute passed. We took one more turn on county road J40 east from V42 to stay out of the path of the funnel. This was a another good decision because two to three minutes later we watched the needle like funnel become a rope tornado and cross V42 close to the intersection we turned east to get out of. A nice debris swirl was visible as it crossed the road. We reported this tornado on the ground to the Des Moines weather office at 3:57pm.
We followed the storm for another 45min after this but never saw it produce again, despite numerous tornado warnings issued for strong rotation. Overall, a very good chase day.
P.S. We figured we would drop off our video at KCCI Des Moines so they could add it to the local storm coverage on the 10 o clock news. Couldn't believe what happened next...we were asked by CBS This Morning to buy our video. Must have been a slow news day I guess!.. but hey it will pay for gas money. Best of luck to everyone else who chased today and the last week. I hope this is a sign of better things to come...
