Isolated thunderstorms developed south of a stalled out cold frontal boundary oriented east to west across the southern South Plains and southern Rolling Plains. Strong instability south of the boundary allowed one thunderstorm to become severe in Stonewall County before moving south.

Area Forecast Discussion National Weather Service Lubbock TX 306 PM CDT Fri Jun 23 2017 .DISCUSSION... Convective chances are somewhat unclear from this afternoon through the next several days. Convection has developed along an advancing cold frontal boundary oriented east-west from the southern South Plains through the southern Rolling Plains. Temperatures in excess of 100 degrees with surface dew points around 50 will support high bases and therefore a wind threat. This front will bring markedly stronger northeasterly winds and these winds will continue overnight. This cold front will bring a very welcome break to the oppressive heat we have experienced that past week or so. Surface ridging will build in overnight behind this front with decreasing winds by mid morning. A subtle short wave aloft may bring thunderstorms from southwestern Oklahoma to the Rolling Plains tonight. However, this convective activity is far from certain. It is now supported by the HRRR and is supported by the TTU WRF to an extent. Elevated instability above the frontal boundary will not be in short supply within strong moist southeasterly winds giving some confidence in this possible overnight convection. Extensive low level stratus casts doubt on convective chances for Saturday especially during the daytime hours. Moist isentropic upglide will keep elevated instability around the area which may be enough to generate scattered showers and thunderstorms. Models are again mixed on how Saturday will play out but widespread severe convection is not anticipated. Northwest flow storms will be more difficult to come by on Saturday evening but will have stronger chances on Sunday evening. Low level flow will be more out of the southeast rather than east with increased instability across the area into eastern New Mexico. Another day with possible northwest flow storms will occur on Monday with a continued weak upper level ridge to the west. This upper ridge will be suppressed for several days this weekend into early next week as an upper level system moves into British Columbia. Tuesday and beyond bring more uncertainty to the forecast as the upper level ridge begins to strengthen again leading to increasing heights. Models are differing on the strength of the system moving out of British Columbia which will affect the strength of the upper ridge. However, this may only mean a difference locally of either 90 or 100 degrees by late next week. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 01
