Storm structure shot with well established wall cloud and funnel cloud forming on the left side.

Cannot confirm this was a tornado due to the condensation funnel not clearly reaching the ground, but it sure tried! Persistent, long funnel for several minutes. First attempt on the first storm of the day.

Confirmed tornado! View of the storm, wall cloud, and tornado underneath. This was around 5-10 minutes after the first funnel dissipated.

Closer shot of the tornado just northeast of Paducah, Texas.

Tornado lifting on the left to a needle funnel at this point. Rising scud into center/right side of wall cloud suggests new tornado will be possible after the first occludes.

Wicked shelf cloud approaching near Silverton, Texas.

Day 7: May 20th, 2019

A high-risk day for the eastern Texas Panhandle and western Oklahoma! Forecast conditions for this day: dew points in the 70’s, CAPE in the 3000-5000 J/kg range, and strong shear had tornadoes written all over it, at least as long as the storms could remain isolated. That was the main concern as the day also came with a weak capping inversion, meaning the storms might not remain isolated for long. The forecast and target area also suggested that the chaser hordes would be out in force. Our plan was to head southwest out of Oklahoma City and play with the initial storms in the warm sector first before they congealed into a line, then head further southwest to the dry line where we expected the biggest, meanest storms to be later on. The hope was also that most of the hordes would stick with the warm front storms as they put OKC under the gun toward evening. It was an ominous forecast: Some schools in the OKC area were closed in anticipation of a major severe weather event.

We departed OKC and headed southwest to Lawton, then west through Altus, heading for our target Childress, TX where we would stop and adjust accordingly. At Altus AFB, they were getting ready, with all the big military planes on the taxi line revved up and ready to get out of harm’s way. Arriving in Childress, the chaser hordes were already there, and we hung out for some time at a Pilot in town with dozens of other chasers waiting for the warm sector to initiate.

After waiting almost two hours in Childress, storms began firing and soon our attention was drawn to a storm heading up from the southwest towards Paducah, so we headed south on Rt. 62 to intercept. But, as we got close to town just minutes ahead of the rotating area of the storm, we ran into construction and were stopped in our tracks waiting for a lead car to return and take us into town. Seeing that we were not go going to beat the storm into town and get to our east option to stay with the storm because of the construction, we headed east on FTM 314 through the mud then south on FTM 301 trying to get back to pavement.

As we got to the junction of the paved FTM 2876, we could observe the wall cloud of our storm just to the west, and soon, tornado! The storm produced a slender elephant trunk tornado hanging off the back of the wall cloud, fully condensed to the ground. The tornado lasted about 7 minutes before roping out into a long-arced needle funnel.

We headed northeast on FTM 2876 and FTM 104 to stay with the storm, which looked to by cycling to our west. After some maneuvering through Kirkland about 30 minutes later, we head briefly west on Rt. 287 and pulled off in the mud near some railroad tracks as the old occluded mesocyclone passed by, and waiting for the new meso to catch back up to us. Once the precipitation core cleared and the mesocyclone passed it was clear the storm had turn HP, but still had a rock-solid updraft as it passed us by.

As the storm passed just to our west, we were faced with a decision: Follow the storm northeast and cross the river back into Oklahoma and thus give up the dry line play, or let the storm go and head back west to set up for the dry line storms that were already firing. We chose the latter and later found out that our storm had produced a strong tornado near Mangum, OK a bit later. Apparently however the chase had been hindered by an enormous line of chase vehicle traffic, so it is unclear if we could have actually gotten to it. We headed back into Childress and stopped back at the same Pilot gas station and waited again, passing through flash-flooded roads caused by the front-flank precipitation core of our previous target storm as it passed through.

After a fairly short pause in Childress, we had a number of cells to choose from as the dryline was now firing, but unfortunately the worst-case scenario was developing: With no cap, too many storms were initiating and they were all interfering with each other and starting to line out. Examining the storms coming towards us we elected to target a storm showing rotation and still somewhat isolated to our northwest heading for Estelline. We headed through Estelline and west out of town a few miles on Rt. 86, but the storm was a big HP mess, burping out a big shelf cloud as it approached from our west.

At this point, things were looking grim for our chase as the storms were becoming more or less a solid line. Close to giving up, we targeted an HP supercell that was embedded in the line coming up from the south. We passed through Childress again, then Paducah on Rt. 83, and headed west on FM 193 to get towards the inflow notch and area of rotation. Passing through Dumont, we continued a few miles further before determining that the storm was right turning and threatening to cut us off. We blasted back east then south towards Guthrie, passing the area of rotation to our west just north of town. Parked along Rt. 83, it was clear there was a tornado embedded in the big core to our west as the sirens went off in town, but there was no way we were ever going to see it so we had to continue south to get out of the way. We made it as far south as FM 448, waiting for the last storm in the line to meet us, but by the time it got to us it had weakened greatly. After waiting and throwing the football around for a while, we gave up and headed east on Rt. 82 and Rt. 277 to our hotel in Wichita Falls, TX for the evening.

The excitement wasn’t <quite> over yet though since as we settled into our rooms there were not one but two tornadic supercells heading almost directly for the hotel about 2 hours away. But after keeping an eye on them for a while it became clear that they would pass north of town and it was off to bed to get ready for the next day. Somewhat of a High risk bust, though there were tornadic storms chugging away through the night keeping just about the whole state of Oklahoma on alert.

Miles for the day were 558.7 for a trip total of 2453.8
