A recurring theme for chasers during May 2017 was disappointment with regard to tornadic activity. \u00a0There were several days with (seemingly) fairly high-end tornado potential, when SPC was advertising the chance for significant and long-lasting tornados. \u00a0But these days fell flat for chasers for the most part. \u00a0Sure, there was the successful tornado intercept here and there on a day or two, but the highly-advertised days wound up being duds for most chasers. \u00a0It seemed that each and every time that SPC drew a 10 percent tornado area, the end results were less-than expected tornado-wise. \u00a0And please do not take this as a knock on the fine forecasters at SPC! \u00a0I am just relating to you, the reader of Stormbruiser chase accounts, how things went this season for me and many chasers.<\/p>\n

This chase day was one of those potential BIG days. \u00a0Look at all of those mesoscale discussions! \u00a0It was the first day for Tour 4, and the shear and instability were looking fabulous for northeastern Oklahoma, especially from Tulsa to the northeastern corner of Oklahoma. \u00a0SPC showed a 10-percent hatched tornado area from Tulsa into Missouri. \u00a0There was also a good chance of supercells in the Oklahoma Panhandle and vicinity, an area I favor for chasing. \u00a0But with the tour, I had to go for the much better tornado prospects. \u00a0After lunch we watched the sky from Stroud, and I think we were looking for an open auto parts store to take care of something with the van. \u00a0But this was a Saturday on Memorial Day weekend, and the small towns were closed up. \u00a0The cap was very strong today (finally — no early development!), and the cumulus fields were struggling. \u00a0A nice area of surface moisture convergence drew us up beyond Tulsa to Vinita, OK. \u00a0A couple of strong updrafts took shape north of I-44 and moved ENE-ward. \u00a0We wound up on a fine candidate for severe weather near Vinita, and it soon had a wall cloud and interesting action area. \u00a0Given the low-level shear, low storm base and big-time CAPE, it would not have been surprising had a significant tornado developed. \u00a0But the storm was having none of that. It continued to the east-northeast, and soon the next storm behind it was raining into it and turning it into a messy HP. \u00a0This was near the southwest side of Miami.<\/p>\n
