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.
