A weak cold front settled into the southern Texas Panhandle during the afternoon of the 29th which initiated isolated thunderstorm development. Sufficient instability combined with a dry and well mixed boundary layer lead to an evaporatively enhanced downdraft near Silverton (Briscoe County) generating a severe wind gust.

Area Forecast Discussion National Weather Service Lubbock TX 237 PM CDT Fri Jul 29 2022 .SHORT TERM... Isolated thunderstorms are possible this afternoon and tonight across the CWA with the greatest chances in the southern Texas Panhandle this evening. A remnant outflow boundary from last nights convection has stalled and weakened just south of the CWA. A cumulus field along with some storm cells are beginning to develop along this boundary as of 19Z. Although weak, this boundary may provide enough forcing for continued isolated thunderstorm development near and along Highway 380. Storms that form will be high based and may be capable of strong downdraft winds. 19Z objective analysis indicates DCAPE around 1000 J/kg with inverted-v sounding profiles across the CWA. Meanwhile, current surface analysis shows a cold front draped across the southern United States spanning from the Tennessee River Valley to the Texas Panhandle. Mid-level water vapor imagery depicts the eastern edge of the monsoonal moisture plume spreading across the Texas Panhandle. CAM guidance suggests that numerous thunderstorms will develop to the north of the LUB CWA this afternoon in this region of enhanced frontogenetic lift. Outflow from convection to the north of the CWA combined with MU CAPE in excess of 1000 J/Kg may be supportive for a complex of thunderstorms to infringe on the northeastern portion of the CWA later this evening and tonight. Otherwise, tomorrow will be hot with afternoon high temperatures in the upper 90s with low chances for precipitation. The potential for thunderstorm development tomorrow will be significantly less than today due to lack of forcing and a drier mid-level atmosphere. .LONG TERM... Ridging over the Pacific Northwest will continue to build and shift east on Sunday. Monsoon moisture on the west side of the ridge axis will therefore be shunted well to the west of our area through most of the extended forecast. The upper level ridge/dome of high pressure will continue to shift east and south over the first half of next week, with the center reemerging over the Texas Panhandle and Oklahoma by Tuesday and Wednesday. The slow and gradual evolution of the synoptic pattern over our region will leave little change in the day-to-day weather over the next week. Temperatures will continue to run around 5 degrees warmer than normal across our entire area, which means less days with triple digit heat for locations on the Caprock and hovering at or slightly above the century mark, east of the escarpment. We will also remain mostly dry across our CWA with some slight chance PoPs glancing our locations along the NM/TX state line late next week as a progressive trough attempts to bend the monsoon fetch to the east from central New Mexico on Friday into the weekend, but confidence is low attm for any widespread meaningful rainfall to result over those locations. We will also continue to see seasonally mild overnight lows, but will at least be a little cooler for most of us than what we've seen the past month or so. && .LUB WATCHES/WARNINGS/ADVISORIES...
