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 10, 4:37 PM CST, 2 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 537 PM CDT SAT AUG 10 2013 .DISCUSSION... See aviation discussion below... && .AVIATION... Scattered showers and thunderstorms continue to affect KJCT, SOA, and BBD. Given the scattered nature of the convection, I have opted to continue with a VATS mention, with most convection dissipating by 03Z. Winds will become light and variable after sunset, then become southeast at 5 to 10 knots by late morning Sunday. Isolated showers and thunderstorms will be possible at any of the TAF sites tomorrow, but given the limited coverage that is expected, I have left any mention out of the TAF's for now. && .PREV DISCUSSION... /ISSUED 359 PM CDT SAT AUG 10 2013/ SHORT TERM... Saturday Night. A few isolated storms will again be possible...but most areas will remain dry. What's left of a weak cold front has stalled and is slowly dissipating across the southern counties this afternoon, from San Saba to Sonora to OZONA. A few thunderstorms have developed along and south of this frontal boundary this afternoon, and should continue through sunset this evening. At best, coverage should remain isolated with gusty winds and lightning the main threats. Otherwise, a slightly cooler air mass, fewer clouds, and light wind should lead to temperatures a few degrees cooler tonight. Did not go as cool as the MET guidance has, but at least cooler than in previous nights. Sunday. A few storms again possible areawide Sunday afternoon. Large Upper Low over the Gulf of Mexico noted on Water Vapor imagery will continue to move west towards the Texas coast on Sunday. Enhanced mid and upper level moisture on its west side may be enough to combine with low level moisture and afternoon heating to aid a few storms in development. We will certainly see a widespread cumulus field, but without a boundary or real upper support to help, getting an actual storm to develop may be tough. Still, cant rule it out and worth a mention of isolated storms. LONG TERM... (Sunday Night through Tuesday) Hotter temperatures are expected Monday and Tuesday with the center of the upper high over West Central Texas. With less diurnal cloud coverage expected and 850 mb temperatures climbing a degree each day, going above a degree or two above mos guidance. should see triple digits for highs across some of our northern and central areas Tuesday. (Wednesday into Saturday) The forecast becomes more problematic with regard to rain chances during the latter half of next week. The 12Z GFS and ECMWF are in general agreement with the upper high shifting to our west and building over the southwestern states. This to occur as shortwave energy dives southeast across the Midwest. The flow aloft over our area will become northwest and eventually north during this time frame. This setup will allow a weak cold front to sag south into West Central Texas. The models differ on how quickly this occurs, and how much convective development occurs in the vicinity of the front. The ECMWF is faster with progress of the front and is more generous with the QPF across our area. At this time the ECMWF looks too aggressive in bringing the cold front through our area Wednesday with QPF, given the forecast position of the upper high and the transition to northwest flow aloft just beginning. Conservatively leaning toward the GFS with timing, with the front entering the northern Big Country Wednesday afternoon and making slower, more gradual progress to the south thereafter. With low-level thermal ridging pattern just ahead of the front progged for Wednesday, temperatures could reach or exceed 100 degrees for highs. Given the aforementioned setup with the flow pattern aloft, could have embedded shortwaves, possibly convectively induced, moving south/southeast into our area late in the week. For now, trending lower with the temperatures with increased cloud cover and expanding POPs across our area late in the week. Anticipate that POPs may need to be increased and temperatures reduced further, once the forecast details become better discerned. && .PRELIMINARY POINT TEMPS/POPS...
