August 28, 2002 Wahpeton, ND Supercell

Well I hoped to get a chase in while taking a class up in ND. Wednesday after class I went back to the motel room and almost fell asleep. I got bored and looked sw out the window and hello...there was a storm that just went up, sw of town(no watch out yet....about to be a severe watch). I went downstairs and grabbed Jon(my supervisor from work...who had never been on a chase) and went outside. Precip began to block the view of the storm. Soon pea sized hail started falling on us. I was like well we'll give it a shot, having no clue what the setup was like at all. The storm was rather elevated. We watched it from this parking lot on the east side of town. |

This scud was quite interesting, rising rapidly up into the base. A tornado warning was issued at this time and that got my hopes up quite a bit. |

We went east into MN on highway 210(I think) and she just about tornadoed for us. Jon had never seen one and I still haven't this year. I tell him at one point that he's about to see one. They were reporting this storm moving ne at 20 mph. I was like, I doubt it's going to move ne here in a minute. It pretty much stopped, then actually dropped south for a bit. |

It went from the previous pic to this in maybe 20-30 seconds. |

I can't believe nothing formed! I thought for sure we were going to have a great view of a tornado, nicely back lit, right off the road from us. We had nice warm easterly inflow at this time. |

Jon points out this interesting thing moving around the mesocyclone. I was like, "hmmm, yes that is interesting lets at least be ready to leave(east)". |
|
|
This is indeed interesting. Notice the bit of "rfd"/clear notch here to the right of the previous feature. |
|
|
Wow, this was turning into a real treat, that is for sure. It had a very rouned base for awhile |
|
|
Look at that feature get pulled cyclonically around the storm. Too bad there was evidently a good wedge of cold air right under that wall cloud. |
|
|
This thing was simply producing too much rain cooled air as it sat there then moved/formed south. It would just about do it before more cold air would undercut the updraft. The town we were staying in (Wahpeton) got 6-10 inches of rain in a 3 hr period. |
