Did it verify
Verified. The Iowa Environmental Mesonet's Cow matched 3 storm reports to this flash flood warning; the first came 172 minutes after it went out.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Corpus Christi, TX (KCRP), launched 00:00Z, 9.8 hours before the alert went out and 261 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

CPWhat forecasters said that day
The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Austin/San Antonio, TX wrote its last area forecast discussion before this flash flood warning went out at Aug 27, 12:05 AM CDT, 4 hours 42 minutes earlier.
Area forecast discussion, Aug 27, 12:05 AM CDT, 4 hours 42 minutes before
Area Forecast Discussion National Weather Service Austin/San Antonio TX 1205 AM CDT Sun Aug 27 2017 .AVIATION... The center of Harvey is located 70 miles SSE of KAUS and 70 miles E of KSAT. Bands of rain with possibly isolated thunderstorms will continue to rotate around the center as it meanders slowly in the same general area overnight through Sunday night. Have kept -RA at KAUS, KSAT, KSSF through the forecast period, although could be brief rain-free periods. IFR/MVFR CIGs/VSBYs will prevail most areas. Cyclonic winds of 20 to 35 KTs with gusts up to 45 KTs are expected overnight into Sunday, then winds will slowly decrease on Sunday into Sunday night as Harvey weakens. Nly winds will prevail at KAUS, KSAT, KSSF. West of a KJCT to KCOT line, VFR skies and Nly winds 5 to 20 KTs will prevail. && .PREV DISCUSSION... /ISSUED 432 PM CDT Sat Aug 26 2017/ .SHORT TERM (Tonight through Sunday Night)... Tropical Storm Harvey nearly stationary over Dewitt county. Moderate to heavy rainbands associated with Harvey continue to push rain rates of 1 to 3 inches per hour along and east of Interstate 35. New rainfall amounts of 2 to 4 inches are possible through late tonight over areas that have already recorded 3 to 8 inches the past 12 hours. Harvey is also producing 20 to 30 mph sustained winds with up to 50 mph wind gusts as of 4 PM CDT, especially, along and east of the I-35 corridor. The winds will decrease this evening as Harvey continues to loose intensity. However, rain will continue to move onshore (rainbands) and fall over almost same areas for next several days, as Harvey is forecast to hardly move off from southeast Texas. The main weather hazard for the area and especially areas east of Interstate 35 and Interstate 37 will be flash flooding and river flooding from now until at least the middle of next week. KEY MESSAGING POINTS: 1) A life-threatening and catastrophic heavy rainfall event is expected east of I-35 and I-37. Radar estimates of 3 to 8 inches have fallen last night through this afternoon near and east of a Austin to Cuero line. 2) Additional rainfall amounts of 10-20 inches are expected east of I-35 and I-37 this afternoon through at least Wednesday. Isolated higher totals up to 30 inches are possible in this area. 3) 8-12 inches in Austin metro with locally higher amounts through at least Wednesday. 4) 5-10 inches in San Antonio metro with locally higher amounts through at least Wednesday. 5) 1-4 inches across the eastern Hill Country through at least Wednesday. 6) Catastrophic main stem river flooding lasting throughout next week is likely east of I-35 and I-37 in the Colorado, Guadalupe, and San Antonio river basins. 40-50 mph wind gusts in Tropical Storm Warning through this evening. 30-40 mph gusts elsewhere. 7) There is an isolated risk for tornadoes east of a I-35 and I-37 through Sunday. These small tornadoes are typically very fast moving and short-lived. .LONG TERM (Monday through Saturday)... Harvey will remain across the area for the next several days as upper level short-waves drop from the central plains into the Ohio Valley on Sunday through Tuesday. In the mean time, Harvey is expected to linger around the southeast counties of South Central Texas or even push closer to the coast before slightly moves to the northeast late Tuesday into Wednesday, thanks to an upper level ridge over the desert southwest expected to move to the east. Unfortunately, the upper level short-wave pattern across the upper Great Lakes/Middle Mississippi Valley is expected to hold back Harvey's moisture across the northeast of South Central Texas through late Friday. It will definitely be a wet period across portions of South Central Texas for the next several days. Please, continue to monitor closely the National Hurricane Center (www.nhc.noaa.gov) and the Austin/San Antonio Weather Forecast Service Office (www.weather.gov/sanantonio) websites for updated information about Harvey and its impacts. && .PRELIMINARY POINT TEMPS/POPS...

Tropical Storm Harvey will continue to slowly move across the southeastern portions of South Central Texas through the period. Widespread heavy rainfall capable of producing river and flash flooding will occur well to the north and east of Harvey circulation. This is a life-threatening and catastrophic heavy rainfall event for areas east of I-35 and I-37. A Tropical Storm Warning is in effect for winds of 35 to 50 mph across Atascosa, Bastrop, Bexar, Caldwell, Fayette, Gonzales, Guadalupe, Lavaca, and Wilson Counties. A Wind Advisory is in effect for Bandera, Blanco, Frio, Kendall, Lee, Medina, Travis, and Williamson Counties for winds of 25 to 35 mph with gusts to 40 mph in the stronger rainbands through this evening. A Flash Flood Watch is in effect through Wednesday evening for counties along and east of a line from Georgetown to Comfort to Jourdanton. There is a low risk of brief tornadoes east of I-35 and I-37 through late tonight. .DAYS TWO THROUGH SEVEN...Sunday through Friday. A Flash Flood Watch is in effect through Wednesday evening for counties along and east of a line from Georgetown to Comfort to Jourdanton. Life-threatening and catastrophic river and flash flooding appears imminent for much of South Central Texas, specifically for areas along and east of the I-35 and I-37 corridors. Additional rainfall amounts through Wednesday of 10 to 20 inches are expected east of I-35 and I-37 with isolated totals in excess of 30 inches possible. Devastating river flooding lasting throughout next week is likely east of I-35 and I-37 in the Colorado, Guadalupe, and San Antonio river basins. 8-12 inches are expected in the Austin metro with locally higher amounts through at least Wednesday. Also, 5-10 inches are expected in the San Antonio metro with locally higher amounts through at least Wednesday. 1-4 inches are expected across the eastern Hill Country through at least Wednesday. .SPOTTER INFORMATION STATEMENT... Spotter activation will be encouraged over the next several days as Harvey evolves.
