The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 21, 5:34 PM CST, 1 hour 46 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 634 PM CDT Wed Jun 21 2017 .AVIATION... Although VFR conditions will prevail for the next 24 hours, there is a chance of TSRA in the vicinity of the terminals from about 03 to 09 UTC. In addition, there is a possibility of strong gust fronts producing strong and erratic winds well ahead of the thunderstorm activity, and possibly some blowing dust as well. KPVW has the highest potential of this occurring tonight and we've added a mention to the TAF to that terminal, with chances lower at KLBB and KCDS. && .PREV DISCUSSION... /issued 305 PM CDT Wed Jun 21 2017/ DISCUSSION... High pressure remains our dominant feature across the SWRN USA. Today, the center of the high is located across SERN AZ with largely zonal flow across the northern half of the country. Across SE TX, T.C. Cindy is expected to make landfall near the TX/LA state line before being swept eastward. The mid level flow should become more northerly through Friday before transitioning back to a more northwesterly flow regime. A few minor ripples in the embedded flow to our north should still drive a cold front into the region on Friday. The upper high to our West will strengthen early next week before the ridge to its north flattens on Tuesday and squeezes the high into the eastern Pacific. Thunderstorms have begun to fire across the higher terrain of northeastern New Mexico. Given the pattern, these storms are expected to work their way across the state line later this evening and provide perhaps the NWRN 1/3 to 1/2 part of our area with rainfall. Some of these storms could become strong to possibly severe with the primary threats being winds to 60 mph and hail to the size of golf balls. The activity should largely start to weaken after midnight. Some risk of northwest flow storms is possible again on Friday though the coverage appears to be less expansive. The cold front should make it into our CWFA by sunrise Friday morning providing for lower temps, particularly in the northwestern zones. Storms will likely fire INVOF the frontal zone though the positioning of the front remains nebulous. Unfortunately, this results in a broadbrush of mild POPs though confidence in somewhere getting storms is moderate to high. Scattered storms are expected to continue into Saturday and Sunday as the frontal boundary remains draped across the area. Naturally, if the front pushes much further south, or remains to our north, this will have a profound impact on the rain chances. However, given the forecast disturbances to our north, there does not appear to make things really drive much further to the south. Still, as evidenced by several previous events earlier this spring, this is a tricky forecast regime compounded by the after-effects of Cindy. Models continue to suggest scattered storms into Monday and Tuesday though these may be the results of feedback mechanisms which may not pan out. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 33
