Damaging Wind in Texas, May 19, 2021
Some residual storms associated with a slow moving upper level low pressure system that generated severe storms the days prior, continued to move across the eastern Texas Panhandle on the 19th. Most of these storms just brought some good rainfall to the area as instability was limited but one them did produce a wind gust of 58 mph as a heavy rainfall and downdraft occurred over the mesonet site…

What happened
The episode as NWS AMA wrote it up.
Some residual storms associated with a slow moving upper level low pressure system that generated severe storms the days prior, continued to move across the eastern Texas Panhandle on the 19th. Most of these storms just brought some good rainfall to the area as instability was limited but one them did produce a wind gust of 58 mph as a heavy rainfall and downdraft occurred over the mesonet site located near Wellington, Texas.

Area forecast discussion, May 19, 5:18 PM CST, 49 minutes before
Area Forecast Discussion National Weather Service Amarillo TX 618 PM CDT Wed May 19 2021 .AVIATION... 00Z TAF Cycle VFR conditions will become IFR to LIFR in low cloudiness and fog at the Amarillo TAF site between about 10Z and 16Z Thursday and possible MVFR ceilings at the Dalhart TAF site between about 10Z and 15Z Thursday, however confidence is low at the Dalhart TAF site at this time. Otherwise, VFR conditions are expected at the Guymon TAF site through 00Z Friday. South to southeast winds 5 to 15 knots increasing to 15 to 25 knots with gusts near 25 to 30 knots at all three TAF sites after 16Z to 19Z Thursday until 00Z Friday. Schneider && .PREV DISCUSSION... /Issued 220 PM CDT Wed May 19 2021/ SHORT TERM (Today through tomorrow night)... Main item of interest in the short term is the thunderstorm potential this afternoon/evening. While a few isolated thunderstorms are possible, it appears our severe weather chances are limited through this evening. Sure, a rogue severe storm could develop, but the chances are low. Wind gusts around 50-60 mph and hail around a nickel/quarter size would be possible with any storm that became severe or near severe. An H5 low is hovering over the vicinity of the Panhandles, and it really doesn't progress east/northeast until later this evening. Water vapor imagery reveals Gulf moisture advecting in across the Southern Plains and wrapping around the low over the Panhandles. The warm moist air is making for pathetic lapse rates (~6-7 C/km) and therefore weak MLCAPE values only around a few hundred joules to upwards near 800 J/kg. Bulk shear is only around 20-30 knots. These are not the best parameters to support updrafts and our thunderstorm potential. If anything, the low level moisture tonight may lead to our more impactful weather being the low level clouds and fog potential. Fog potential could bring visibilities down to around 5 miles with patchy areas under a mile, but confidence is low on the fog, especially less than 5 miles. Tomorrow our lapse rates are a little better (~7-8 C/km) which leads to better MLCAPE around 1000-1500 J/kg with higher amounts in the north. Bulk shear is only 30 knots. With the exiting H5 low there may be a lot of subsidence around tomorrow, and without the forcing aloft our thunderstorms chances are very low. If we happen to get a rogue storm, it could end up becoming severe with minimum criteria possible. Confidence is much higher that we remain precipitation free across the Panhandles, but if we do get a thunderstorm it may end up across the northern half of the Panhandles. Guerrero LONG TERM... On Friday an upper level high will be located over Kentucky and an upper level low will be located over Nevada. This will put the Panhandles under a southwest flow aloft. This flow will help to strengthen the lee-side surface trough across eastern New Mexico. Low level southeast winds across the Panhandles ahead of the surface trough will help to draw Gulf of Mexico moisture into our region. The surface trough will likely be a focus for afternoon showers and thunderstorms which will slowly move into the Panhandles late Friday afternoon and Friday night. On Saturday, more showers and thunderstorms are expected to develop to our west which will again move this way later in the afternoon and overnight. On Sunday, the bottom part of the upper trough will kick east and northeast across the 4-corners region and across Colorado. This will help to increase the upper level flow across the Panhandles which may help to produce some more robust thunderstorms on this day. The upper level high across the eastern U.S. will move southward on Monday allowing the upper level low to rotate northeast into south central Canada. But, a new upper level trough will move into the Pacific northwest by Tuesday which will keep a weak southwest flow aloft across the Panhandles. This weak southwest flow will maintain a surface lee-side trough/dryline across eastern New Mexico both Monday and Tuesday. So, again diurnally driven thunderstorms will be possible Monday and Tuesday across the area. && .AMA Watches/Warnings/Advisories... TX...None. OK...None. && 11
