6/25/10 Reports: NE/IA/MN

[AndyGabrielson]

Captured a tornado near Lamberton around 5pm, then captured an incredible pair of tornadoes within an hour at night between 10 and 11pm (central time), one near Sibley, IA and one near Sanborn, IA... Heres the video http://www.youtube.com/watch?v=IwPMX5Pf9Ow Hope everyone stayed safe, saw some serious destruction along Highway 9 near Little Rock, IA... also saw a car which looked to have been picked up by the tornado on HWY 60 near Sibley just after the tornado lifted, was told there was some injuries possibly resulting from that.

After bouncing between a couple cells near Redwood Falls, MN, we made the decision to drop southwest and get on the most westerly convection in the line. It turned out to be a good outcome, as our route gave us perfect positioning to capture a beautiful tornado near Revere, MN.

We'll be posting a video soon.

On the Thedford, Nebraska storms from initiation producing 3-4 landspout tornadoes.

















NWS LBF has a good report with radar imagery HERE

Saw a few funnel clouds between Tracy and Walnut Grove MN. Then I was headed home, but as I was at the gas station in Rock Rapids the cell to the east looked really interesting so I headed back out. When I was about 4 miles south of Ellsworth I saw what at the time I thought was just a funnel but after heading farther east realized was a tornado. Saw pretty bad damage west of Little Rock on highway 9(small buildings down and powerline poles tilted over). I tried to continue after the storm to keep reporting but couldn't keep up due to damage. As I got a few miles south of Little Rock I could no longer go south due to the damage. There were large trees completely stripped and powerlines on the road. The little video I got is yet to come. I got more video of the MN part of the storm because at first when I saw the funnels on the IA storm it wasn't tornado warned so reporting was the #1 priority then.

I've added a couple of still of the storm near litte rock

We chased the front of the line in MN, and eventually dropped south to try and roll over the cell that passed directly over Mankato. Saw some very strong rotation and several wall clouds. At one point we needed to fall back because some "friendly" little landspouts started getting their act together and the storm looked like it was back building. Saw some very cool anti-cyclonic funnels in the wake of this storm.

When we realized that whatever was in the Mankato cell was completely rain wrapped, we fell back and picked up some 2"+ hail out of a field. We ended the night in a car wash letting the core overtake us. Very intense and close CG.

I had an exciting four-hour chase stair-stepping south and east in front of the eastern end of the line of storms that developed in southwestern Minnesota.

When the first cell fired west of Montevideo around 4 p.m. I was well to the south at the intersection of U.S. 71 and U.S. 14. The cell was TOR-warned almost immediately, but once I was north of Marshall on MN 23 I opted to check out two smaller cells that were going up just to my east. All three cells started to congeal, but the southern most part of the line still looked good on radar. That part of the storm developed a nice, rotating wall could over Morgan, MN (first picture).

The second picture shows another strongly rotating wall cloud just north of Sleepy Eye, MN. The rest of the chase, though, looked like the last photo - a large, menacing HP beast grinding along to the southeast. Toward the end of the chase I tried but failed to get far enough east to peer into the storm's well-formed inflow notch. I then called it a day in Amboy, MN.

Congrats to all who bagged the tornadoes at the western end of the line!

finally have the video up from this day. In the last couple of minutes you can see the tornado between lightning flashes if you look close, the pics in my previous post are stills from the video.

Targeted Tracy, MN. Watched on radar that shower to my northwest explode in to the supercell west of Montevideo. Got north, intercepted it, saw some great structure. Followed the HP mess to I90, and ran in to flooding problems in Blue Earth trying to get home. All in all a fun day, but it's too bad the storms couldn't stay more isolated longer. Oh well, still a good day.
Getting on the tor warned storm east of Montevideo:

Short after, this thing ALMOST did it, the rotation brought back memories of 6/17 near Leaf Valley. I thought for sure we were gonna have another multi vortex, but just couldn't quite do it:

Damn powerlines!

The shelf just south of I90:

By far the best anvil crawlers I have seen in the past 5 years after the storms sank into Iowa.

Caught this tornado, just south of Thedford, NE around 7:15pm CDT on 6/25. I was on the east side of the storm and this shot is looking west. Steve Miller has shots of this same tornado from his vantage point on the opposite side.

Targeted Marshall, Minnesota and opted for the cells developing south of the initial tornado warned Montevideo cell. Paralleled them to their south along Hwy. 14 where they merged and became tornado warned near Redwood Falls. The now single cell turned right from an easterly direction to a SSE direction allowing for a relatively easy intercept of the meso a few miles ENE of Sleepy Eye. Less than a mile to my north a wall cloud was present exhibiting persistent horizontal rotation as well as slight vertical motions. Surface winds initially were slightly veered from the SSW with the wall cloud moving slowly to the ESE. A clear slot developed to it's WNW with the occlusion downdraft subsequently causing the wall cloud to distend and lose its organization.

The cell quickly assumed HP characteristics before congealing with neighboring cells, resulting in it being one of a cluster of embedded cells along a mostly southward moving line. I followed my cell of interest south where it did show promise once more as the area of circulation approached the town of Hanska. It never could tighten up though and I abandoned it, departing through town to the sound of tornado sirens and what seemed like the entire town's population outside watching the show.

I swung to the west end of the line near Windom but instead of playing the tail-end cell I decided to have fun playing cat and mouse with the surging bow. In retrospect I should have stayed with the end cell that went on to produce the tornadoes later that night but I'm not sure I would have witnessed them anyway as I'm not a big fan of messing with mesos after dark.
