Iowa was the place to be in 2023 (and yes, I realize that rhymes.. Yippie)… so with another setup looming, I headed out to see if I could add to my Iowa count.  After Ottumwa earlier in the season, I knew it would be hard to top, but the setup had some potential, so off I went the day before on a drizzly drive out I-80 toward the Omaha area where I was going to bunk down for the night.

Got up the following morning and did my usual look at the models over a hotel breakfast.  With an early initiation looking likely, it was an early get out for me.  Loaded up the car and didn’t have to drive far; only the hour and change east toward the Des Moines area where I stopped for a quick lunch and before long, was already watching cells go up.

First song I heard in the AM on my way out. Figured it was appropriate.

Storms got going south of the Des Moines area, so I hopped south via US-65 to Indianola, then eastbound on IA-92.  The cell was rotating like a top, and I thought for sure it was gonna thrown down a hog… instead, it let out a birdfart… regardless, it was the first of a few birdfarts..

This wispy looking piddle bucket teased us south of the highway near Sandyville, IA

The storm was fortunately on a very good path, keeping me on IA-92, eventually IA-5 toward Knoxville.  By this point, a chaser conga line had formed on the highway as all of us were hoping to do a little better with this storm.

Looking north toward the town of Knoxville, IA at chasers lined up on the road.
Intense cloud-based rotation as the storm passed over town, but no tornado… yet…

North of town, the circulation really tightened up… and just like the tornado before, it started making it happen…

Wispy clouds again start making contact with the ground…

I pursued this feature north with it crossing IA-14… needing to decide the best route back to the business end of this storm, I decided it would be quicker to get north of Lake Red Rock and take a little piddle road (Hwy G 28) to Pella, then drop south back in front of this thing.  Fortunately it was moving slow enough to make that happen.  Once I got to Pella, I dropped south out of there on Marion County Hwy 117, punching through a pretty benign core (the heaviest part still to my west at this point).

As I got near the River, the road makes a hard pivot back west.  With a view into the area of circulation, I could make out what looked to be a pretty stout looking cone.  Conveniently for me, what was probably the best looking tornado of this storm was shrouded deep in rain, so I only got a fleeting look at it from my north position.

Contrast-enhanced shot of a cone behind the rain.

I followed this storm to Oskaloosa, but with nothing exciting going on, I took the opportunity to gas up, grab a bite, and decide my next course of action.  Another promising cell to the west gave me enough reason to not directly high-tail it back to Des Moines, so I retraced my path back along IA-5/92 and found myself on what was easily the storm of the day.

Arriving to the storm near Ackworth, another slow-moving east-moving cell on IA-92.
Beautiful wall cloud spinning to beat the band near Pleasantville, IA.

I don’t know how this thing didn’t drop a show… the rotation at the cloud base was probably as intense as I have seen.  And many times, it looked like it was close.

The wall cloud continued to spin along, and with a host of chasers lined up on area roads, it finally put down…

This was the best looking visual the Donnelley storm put out, a brief, weak touchdown counted for the fourth tornado of the day.

This show seemed to linger for a while, but after this impressive attempt, the funnel retracted into the clouds.  I didn’t stick with the storm too terribly long, working my way east back to Knoxville before opting to call it for the day.  Figuring it was early enough and I wasn’t far from Des Moines, I booked myself a room and worked my way back to Des Moines for a celebratory steak dinner to ring in yet another successful Iowa chase.
