This image shows a supercell that has split near Yankton, SD and Vermillion, SD. One has cyclonic circulation, the other was has anticyclonic circulation. This occured on May 21, 2004 at 9 pm.


This outlook is from May 22, 2004, the same day that a town south of Lincoln, NE called Hallem got destroyed by a tornado. The tornado was classified as a F4. As you can see, SPC had them in a high risk that day.


Here is a tornado from that area that same day as the Hallem, NE tornado. This was not the one that hit the city. Ironic enough, Hallam is only an hour from where I lived, but I went to Columbus, NE to chase. Obviously, that was a mistake as we saw almost nothing.


This is from our chase on May 22, 2004. We are sitting in Fremont, NE looking towards the west at a supercell near Columbus. The picture doesn't do it justice.


This picture is much better from the Columbus supercell. You can see a wall cloud just to the right of the road in the picture. This storm produced a tornado, but was rain wrapped and it happened much later after this picture was taken.


Here is another picture of that wall cloud only from a bit closer perspective.


This is the RUC model sounding from Beatrice, NE early in the day on May 22. This would have been for 00z that day. It looked excellent for tornadoes and supercells. Beatrice is 35 miles away from Hallam, NE.


This is the graphic from SPC of the severe reports from May 22, 2004. As you can see, there were plenty of tornadoes this day.


This is the SPC outlook for May 24, 2004. This is the day that a wall cloud passed right over my house and tied for the shortest storm chase I've ever had!


This is the tornado probability outlook for that same day.


This is the radar image at the moment or shortly after the wall cloud passed over our house in Bellevue, NE. It's located just south of Omaha. I was very close to going to my basement, which rarely happens unless I know we are gonna be hit.


Here are the watches that were in effect on May 24. Omaha and Bellevue are both in the PDS watch boxes.


This picture was taken from my backyard in Bellevue, NE looking south. You can see some towering cumulus to the south through some holes in the cloud cover.


Looking to the west from my backyard at the approaching storm that produced a wall cloud right over our house.


Another picture looking to the west and if you look carefully, you can begin to see the lowering which would later become the wall cloud.


A view of the storm looking to the north towards downtown Omaha.


A view of the storm to the northwest.


This is the SPC outlook from May 29, 2004. Again, there is a huge area of high risk for severe weather and of course, I went chasing. I went chasing this time with Dan Rajewski who lives in Lincoln, NE.


This is the tornado probability for that same day. A huge area of 25% area of tornadoes.


Here are the severe reports from that day. This was the largest outbreak of tornadoes yet, and the most deadly outbreak of the 3 on this webpage. It killed at least 3 people in Missouri.
