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 San Angelo, TX wrote its last area forecast discussion before the first event at Aug 15, 11:44 AM CST, 2 hours 19 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 1244 PM CDT Thu Aug 15 2013 .UPDATE... Increased POPS this afternoon. && .DISCUSSION... Isolated convection has formed across the Big Country early this afternoon with agitated cumulus increasing in coverage, especially northern and eastern sections. Latest HRRR develops scattered convection across the area this afternoon within a moderately unstable airmass and diminishing CIN. Given latest trends, POPS were increased to 30 percent across the eastern half of the CWA with slight chance elsewhere. Cannot rule out a strong storm or two given an increase in shear aloft and modest instability. The main threat from the stronger storms will be gusty winds with the potential for isolated severe downbursts. Aviation discussion follows. && .AVIATION... Predominantly a VFR forecast the next 24 hours. Scattered showers and thunderstorms will develop across the area this afternoon. Included VCTS at KABI, KJCT and KBBD where better coverage is expected and will monitor convective trends for necessary amendments this afternoon. Any storms will be capable of producing brief MVFR conditions along with gusty winds. A complex of storms may approach the KABI terminal from the north after 06Z tonight but confidence in this scenario is too low to mention at this time. && .PREV DISCUSSION... /ISSUED 625 AM CDT THU AUG 15 2013/ UPDATE... See 12Z aviation discussion below. AVIATION... VFR conditions should prevail across most terminals for most of the day. However, scattered thunderstorms will continue through the period. Given the uncertain timing and location of the storms, not going to mention in the forecast at this time. However, if a storm does pass over a terminal, then a quick drop to MVFR or even briefly IFR conditions will be likely. In addition, gusty winds and cloud to ground lightning will pose a threat. PREV DISCUSSION... /ISSUED 400 AM CDT THU AUG 15 2013/ SHORT TERM... Today and Tonight. Another chance of storms across the northwest Big Country this morning, and across much of the Big Country again late tonight. For the second night in a row, a complex of showers and storms is moving southeast towards the Big Country this morning. Much like earlier this morning, expect the activity to move southeast through sunrise and then quickly weaken and dissipate by mid morning. Will increase precipitation chances slightly across the area northwest of Abilene, but will wait and see how much progress the storms make before increasing them for the city itself. Other showers and storms have lingered across the Northwest Hill Country and the Northern Edwards Plateau early this morning. This activity is much more scattered and has weakened quicker than the storms farther north. At this point, will not boost pops in this southern area, and assume that they will weaken and dissipate even earlier, probably even before sunrise. Large upper level high pressure will continue across the southwest US, creating northwest and northerly flow through tonight. Models have some differences in the possibilities of more storms late tonight across the Big Country, with the NAM showing a potent shortwave generating another MCS moving south into the area late this evening and into the early morning hours. SPC is going along with this scenario and has placed a small portion of the Big Country into a Slight Risk for severe storms tonight. GFS is a little farther east with the storm complex, and slower as well, not bringing the rain into the area til near or after sunrise Friday morning. Confidence in the storm complex is fairly high, but given the uncertainty in the timing and track, will boost rain chances mainly across Haskell and Throckmorton counties for now. LONG TERM... Friday through next Wednesday. An MCS is expected to be diminishing across the northern part of the area Friday morning. How far south the complex will make it isn't known...but it's possible that it could be as far south as the Concho Valley and Heartland areas before finally dissipating. This argues for expanding the chance PoPs into the Concho Valley and Heartland areas for Friday, but mainly for morning activity. This complex would also likely leave an outflow boundary in the area for new thunderstorm development by Friday afternoon...so will keep the slight chance for showers and thunderstorms across the southern areas of the CWA for Friday as well. As flow aloft weakens through early next week, and the ridge expands back over the area, we continue to expect a dry forecast through next Tuesday with temperatures generally a few degrees above normal. By the middle of next week...both the GFS and EC show the easterly wave/trough currently in the western Caribbean moving into the Texas gulf coast and toward west central Texas. At this time, the main affect we will show is slightly cooler temperatures associated with lower heights from this feature for Wednesday. However...should the trough remain in tact into west central Texas, we may have another chance for showers and thunderstorms by Wednesday. && .PRELIMINARY POINT TEMPS/POPS...
