Signal Hill tornado, EF0, 659-7:00. First screencap around formation time. Note the presence of a mesovortex (see storm relative velocity upper right and normalized rotation lower right).  Second screen cap after dissipation time.  |

Not sure I’ve ever seen a storm motion like that.

Look at that OKC sounding tonight. Large hodographs with sharp kinks ("sickle shape") like this are often associated with intense supercells and tornadoes.  |

Not sure I’ve ever seen a storm motion like that. Deviant tornado motions were just west of due north. Cameron Nixon posted this earlier today: |

Tornado was probably moving northwest prior to dissipation. IIRC, the 2007 Greensburg, KS EF-5 tornado moved almost due N and then took a left (NW) turn before dissipating. |

CAMs look fairly anemic with the storms later this afternoon, but they do show 1500-2000j/kg CAPE and ~30kts bulk shear so definitely some potential there. Looks like more widespread cloud cover than the last couple events may lower the destabilization a bit...and lapse rates aren't overly impressive. HRRR does have moderate supercell parameter ahead of the front...so a few stronger cores may develop and pose a marginal hail and weaker tornado threat along with the wind potential.

Seems like a strong little cell will clip the west plex.
And it is not really an out flow as that is by columbia, it may get a little hairy in the metro between 3 and 7.
Also very windy today.

Those winds helping keep the temperature down in my house - feels good, but yesterday was a pain as I tried to mow. Med range, talking next week, which is last week of April, things looking pretty active as a series of low pressures and disturbances from the southern plains track to our south, and make the turn in what many refer to as our wheelhouse. Both GFS and EC has this overall pattern. With cool air in place, it looks like a prolonged period of soaking rains possible at some point, especially along and south of 70 in MO, and adjacent areas in Illinois. The cool air in place means temperatures won't get too out of hand between systems like they have so far this Spring season. Of course, mother nature likes to even things out, so we'll pay a price, I'm sure. But for now, temperature variation will be in check, with overall normal to slightly below normal temperatures; a peak slightly above normal possible here and there in the day to day run of temperatures, and an occasional well below normal day as well, but overall, pleasant. Some nights downright chilly for late April, so disconnect those outdoor faucets.

Woah is right...fujiwara mesos and cell mergers galore. That would have been spooky to chase. |

I have VIL related question.
The website hailstrike.com produces hail reports for a given address. I have one that was pulled by my contractor and it uses Evansville as the data for size, speed, and direction. Would Evansville show larger or smaller hail at the same point in Belleville than the STL radar site?
