Details
"Wednesday: Another MCS day in the Midwest. Southeast moving and propagating line of storms. I don't see a solid chase target again here, but would just see what pops up if you happen to be in the area. I'll probably just hold here in town and be in "spotter mode" with storms going up in a high CAPE, undersheared environment."
I met up with Anton and Tracie Seimon for a local chase around the Decatur area. A supercell was taking shape southeast of the city. Temperature / dewpoint spreads were high and the environment undersheared, however, so the storm quickly developed a massive, cold precipitation core and gusted out. It looked menacing for a bit with an attempt at a wall cloud and big dust plumes under the gust front, but scud and whale's mouths were all that followed as the complex went outflow dominant.
Conclusion
Low odds local play didn't pan out and this chase got marked up as a bust. It had a couple of photogenic moments at the very start and very end, however.
Lessons Learned
- Get on the cells early with a high t/td spread and light shear, as they'll gust out quickly.
