Most surprisingly, there were almost no supercell storms in the prime part of the warm sector across southwest Oklahoma, south of a warm front and well east of the cold front/dryline, where the air was most unstable and wind shear was amply supportive of high-end twisters. Looking back now with far more experience in my pocket, we didn't see anything particularly incredible that week. A brief tornado had apparently already occurred while we were still west of Childress . For that we should all be thankful even us storm chasers who want nothing more than to chase on a day with the feel.

Photogenic and tornadic mothership supercell. Neither RAP nor ERA5 will not perfectly represent the observed environment. The professionals are in a very tough position, having to carefully evaluate and balance two ends of a spectrum: miss a critical forecast for widespread, severe storms and many lives could be unnecessarily lost, vs. over-forecast an event and face criticism and potential loss of credibility for the next go-round.
