Total Distance: 620 miles
Two supercells produced more than a half-dozen tornadoes from NW of Clarendon, TX, to N of Alanreed, TX, straddling I40. We watched the first supercell produce several tornadoes (from at least two mesocyclones) at our location near Jericho, TX, about a mile or two S of I40. As this was going on, I noticed another tornado from a second supercell to our distant southwest; we were watching two tornadoes from two different supercells on the ground at the same time.
The northern supercell, upon crossing I40, took on a very wet, HP look to it, and we were not encouraged by the cooler surface temperatures across the east-central and northeastern panhandle. As such, we let this supercell move away to our northeast as we waited for the southern supercell to approach. This supercell had considerable low-level rotation south of I40, but it was quite chaotic and disorganized; likely not coincidentally, the storm did not feature an observable RFD at this time. Without another supercell to the south, we followed this storm E on I40 as extremely strong low-level rotation developed just ENE of Jericho N of I40. To get a closer view, we headed NNW out of Alanreed, watching a tornado to our NW. We found a good place to stop and observe the storm a few miles NNW of Alanreed, a location from which we watched another strong low-level meso produce at least a couple of tornadoes. Immediately before we left (to avoid getting munched), the meso looked more like a tornado, with at least a couple of well-defined, fully-condensed vorticies rotating around the periphery of the rotation.
By this time, convection nearby had increased in spatial extent, and we weren't very optimistic about the prospects for discrete convection. After turning back to the south to avoid being overtaken by the heavy precip, then, we decided to target the supercell to the W of Paducah, TX. We eventually got a view of this supercell at our location near Swearingen (NE of Paducah), but darkness, the HP nature of the storm, and some bad terrain resulted in our inability to see much of the storm. With sun having set, we decided to call off the chase.
I'm not sure how arrive at a "tornado count" for this chase, since we saw several vorticies that occurred along the periphery of the larger low-level mesocyclones. I'll say we have 6 "quality" tornadoes, with a couple more condensed vorticies that I won't label as distinct "tornadoes". *shrug*
