SW Iowa Tornadic supercell – 6/28/17   Leave a comment

After an exciting night of a line of storms crossing Nebraska, I was about to head back home. I wasn’t sure if SE Nebraska could get heated up enough to produce supercell thunderstorms. After looking at the surface data, there was a strong surface low over Wisconsin and a cold front making it’s way SE. Dewpoints were in the 70’s + and there was an area of strong heating which would allow for convective initiation. I was able to be around Nebraska City and watch the first supercell develop into Iowa. The storm intensified rapidly and was rotating early on. It produced it’s first tornado by Shenandoah, IA. The tornado maintained for quite some distance eastward along state hwy 2. It never got very big but the storm rotation was constant and allowed for an exciting chase.
Here are some images of the first tornado:

The second tornado became obscured by rain but I was able to see it as the rfd winds blasted my car. This was the first tornadic storm in what was to be a tornado outbreak for IA and parts of MO.

MN and SD storms – 2016 & 2017   Leave a comment

Here’s are two images from 7/5/16 and 1 from 6/13/17. The first was a tornadic supercell in West Central, MN with confirmed tornadoes, I managed to capture one during my reposition but from a distance. The issue was I wanted to stair-step some roads but the farm roads had run out. This happens from time to time especially with big high-precipitation storms. The Second storm was more recent with a relatively fast tornadic supercell coming up from the Nebraska border area. I caught up with the storm and managed to get some photos of the ground scrubbing supercell.

Interesting structure from this Summer storm.

Notice the low cloud base of the storm, that coupled with the high precipitation makes for an interesting structure.I assume a tornado occurred at one point but would have been hard to see with the low cloud base.

July 6th 2016 – Nebraska Sandhills Supercell and tornadoes   Leave a comment

July 6th 2016, my initial assesment of this day was it was looking a little more promising to be able to chase a supercell with the surface winds backed and the warm moist air to sustain deep moist convection. It was also looking like a severe outbreak that was going to eventually form into a derecho wind event. By the time I made it to near the Badlands storms were beginning to develop about equal distance from where I was. I saw one thunderstorm top in SW South Dakota. I chose that and made my way slowly south.
By the time I made it in range of the storm it had started on a more Southeast course. At this time radar looked weak; little did I know that this was because the storm had moved too far from the station and wasn’t showing the whole reflection.
I had made it to the 61 and kept driving south with a secondary storm looming. So visually I knew I had to keep going south. Eventually I gained visual on the target supercell and witnessed the rope out of a tornado from quite a distance. This tornado was documented near the Chadron/Haysprings area of Nebraska.
The Nebraska Sandhills are an amazing geographical landscape should be examined on Google maps. Not a lot of farming/farm roads, but there are a few N/S roads on an area made up of prairie sand and grass. It’s a very hilly terrain with frequent valleys and peaks.
I did make one attempt to get closer by trying a side road but I decided by the time I would have made it anywhere the precipitation would be over me. After pulling off on viewpoint area I was finally rewarded with a tornado on the ground. Since I don’t have the optics of the video camera anymore I do have my wide angle so even though the tornado was decent viewing at the distance from the naked eye the wide angle images need to be cropped to get a better idea of the shape of the tornado which for the most part was a trunk tornado. Here is a group of cropped images:

After the tornado dissipated The storm was actually getting closer to the road I was on due to the Southeast course it was on. Eventually at one place I stopped the storm seemed to have a dragging wall cloud yet I knew it meant business because of some vorticies coming down and a rotating rain curtain.

Here’s an image of the storm with some some vorticies coming down.

Here’s some images of the next tornado evolution. This storm had a very pronounced mesocyclone and an ominous tornado underneath.

The storm eventually crossed over the road and I decided to go with what I have seen. I’m still processing what I have witnessed and got to see a powerful storm without any damage. This is definitely a finale to this storm season.
In summary I believe with the tornadoes this storm produced as well as from other storms this can be considered a small outbreak for this region of Nebraska.

5/21/16 West Central Kansas Supercell and Tornadoes   Leave a comment

After a fresh start in Nebraska I drove down to Kansas around the I-70 corridor. The winds were backed in this high plains region and a decent Rockies surface low. Dew points in the low 60’s made their way up to the area I had decided on. After waiting patiently cumulus towers started initiating. Initially the main storm was enshrouded by rain. The roads at this time were pretty well saturated by the first two cells that passed through the area, yet the roads were still solid enough to proceed on with the right vehichle.

Soon the cell started getting some visible rotation to it and I witnessed a multivortex type rotation and then a small tornado planted down (I believe another tornado was possibly ongoing in the rain).

After the tornado spun off into the meso precipitation I changed position in order to get a better structure shot of the supercell. This is generally a good rule especially when you have storms of this magnitude. Here is a scene at a distance with a possible tornado obscured by rain.

Here is another structure shot with an enshrouded tornado under the meso. Inflow winds at this time felt like they were 50-60mph where I was.

This storm remained relatively slow moving if not stationary. I’m sure it produced multiple tornadoes obscured by rain. If the roads weren’t rain soaked I might have tried a different veiw but for the most part I’m satisfied with how this day went. I don’t know if there was any structural damage since it did seem to be out in the open fields.

5/16/16 High Plains: Supercell with Tornado in the OK Panhandle   Leave a comment

I witnessed a decent tornadic supercell on 5/16/16. After chasing some relatively non-eventful storm days, I ended up making another trip down to the SW Kansas area where I was hoping the models would be correct. With the overnight storms previously leaving a relatively cool, moist boundary there was an area to the West that was showing signs of good surface heating. Sure enough some storms initiated and eventually reached severe criteria near the dryline/higher elevation of SE Colorado. I caught up with the dominate storm near Boise City, OK. Sure enough I was suprisingly pleased to see a very solid updraft even from a distance. I got to document some of this structure as well as capture a “bears cage” tornado before having to reposition to avoid the advancing hail core.
Here are the still images and video captures of the storm:

After my reposition two of the storms had merged and ended up having two mesocyclones that were tornado warned, yet the storms had taken on a more high based nature. I believe there was a tornado documented that I missed but I did get behind the storm and had to bail out due to hail. This was an excellent storm chase in open country on the high plains.

First tornadic storm 2016 – North Central Kansas 4/24/16   Leave a comment

I chased in North Central Kansas on 4/24/16. I woke up at a hotel in the Kansas City area. I figured I would drive West on the 36 in case storms fired closer to the Nebraska border.
I ended up seeing a storm that was tornadic North of the I-70 and the West of the 81. I initially viewed a wall cloud with a rapid inflow tail feeding into it. I videoed what may have been a tornado in the rain. I kept up with the storm and took pictures of the storm and eventually left it to pursue some more storms initiating at sunset.
After dodging a couple of hail cores I waited for the evening storms to pass and was done. It turns out this was a more eventful day for me than the 26th which was looking to have a lot of tornado potential but never produced.
First views of the storm with a possible tornado in the rain:

Wyoming Supercell: Tornadic Development After Dark   Leave a comment

Here are some video captures of what visibly looked like a decent sized tornado developing around 10pm on 6/3/15. I had been chasing this storm from it’s initial development taking pictures of a pretty decent supercell. The storm was relatively slow moving so I followed it along the 270 near Guernsey, Wy. I did see what could have been a tornado behind the meso precipitation. After darkness started to fall I remained to the south as the storm moved away. Here are a few captures of what I believe to be a tornado even though it’s hard to be a hundred percent sure with no view of ground contact:







I will post the daytime shots of the storm eventually. I had no radar data here to compare the storm to but I’m pretty sure with the inflow winds into this storm of what I was seeing.

Here are the still photos I took before the after dark tornado:
