05/30/07 REPORTS: ND

The morning was cool and cloudy so I wasn't expecting much more than a rain shower during the afternoon. Turns out there was a couple hours of clearing during the afternoon along with a moisture axis moving into my area. The NWS issued a tornado warning for Cass County on a cell about 75 miles southwest of me but I still wasn't with the program... I looked at the radar and saw a small but rubust cell just to my southeast. I wait for this cell to hit while playing "Cars" by Snow Patrol to the wife for brownie points. The rain hits and then comes down with a vengeance. I estimate an inch or more fell in less than 20 minutes. I look out my front window and see the road is flooded with water just an inch or two below the car door. This brought back memories of 2002 when I did have a car flood in similar fashion in St. Cloud, MN when over four inches fell in less than an hour. Since the rain stopped and water was no longer rising I was in no rush to move the car. Unfortunately, idiots in large trucks decide the drive down the flooded road at high speed creating a nice wake. Luckily the driver's side was a little higher than the passenger side and no water got in the car. After all this distraction I finally look at the storm now just to my northwest and get stoked. If it looks like a supercell and smells like a supercell then it must be a supercell. It was neat watching cloud elements at different levels move in differing directions. Remembering there was an earlier tornado warning on a different storm I find a clearer view and wait. No tornado but a very nice looking storm. Total chase miles: 1/4. Total miles in car: 0. I finally figure a peek at some SPC Mesoanalysis graphics couldn't hurt and sure enough their were plenty of parameters in place for supercells and tornadoes assuming the RUC data was giving a reasonable approximation of the atmosphere.

Additional pics and a few SPC mesoanalysis grabs on on my website.
