Chased with Jacob today. A very vigorous warm front was progged to setup over southeast South Dakota. Ridiculously high cape values (4000+) combined with a ton of wind shear on the warm front lead to the SPC putting out a hatched 10% risk over southeast South Dakota/northeast Nebraska.
We targeted Yankton as we figured we could decide from there whether or not we needed to cross the river and go into Nebraska. The hope was that we could stay in South Dakota to avoid any issues with chaser convergence in getting back across the river when storms crossed the river. Mother nature took care of that for us though as the early morning convection prevented the warm front from lifting as far north as was initially thought and thus we had to go south into Nebraska. We first sat near the town of Magnet around 3pm and watched for awhile. There was some cumulus in the area so it actually looked like things might go up soon. Eventually the cumulus went away though so we decided to head west near Creighton where there was still some cumulus. We sat in front of a field and watched numerous towers try to go up.
We must have seen 10-15 individual towers try to go up, each one getting a little higher but then toppling over and then all of the sudden a really nice tower started going up. We thought for sure this one was going to do it and even the SPC pulled the trigger on issuing a tornado watch but eventually this one also toppled over.
After that tower failed, nothing really tried again to go up. It was so hot that we used the tail gate of Jacobís car as shade and a view finder.
We gave it probably another hour but it became obvious that the cap wasnít going to break so we headed north towards an elevated supercell in South Dakota. Along the way we drove through some beautiful terrain with rolling hills and then stopped for some photos at the Missouri river crossing.
Eventually we caught up to the supercell near Mitchell, SD but it didnít look too impressive. As we drove east along side this thing, we encountered some insane inflow winds so we decided to pull over and get some video. We estimated that the winds were close to 50mph. There was debris blowing everywhere and the car was shaking like crazy. The best part was that when we started heading east again, there was a cow on the side of the road peeing and you could see the piss blowing everywhere with the wind! It was even blowing all over another cow standing right next to him. It was absolutely hilarious. Definitely put a nice mark on an unfortunate day. So, my first chase in Nebraska was a bust but we still got to see storms, we got to see some beautiful terrain and the cow pissing in 50mph wind was icing on the cake.
