The local office's own words before this special weather statement 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 special weather statement went out at Apr 3, 1:57 PM CDT, 1 hour 16 minutes earlier.
Area forecast discussion, Apr 3, 1:57 PM CDT, 1 hour 16 minutes before
Area Forecast Discussion National Weather Service Austin/San Antonio TX 157 PM CDT Fri Apr 3 2020 .SHORT TERM (Tonight through Saturday Night)... The strong April cold front is entering our northern counties at this time with the upper 50s already reported in Llano County. Ahead of this frontal boundary, there have been some breaks in the clouds which has allowed temperatures to warm up into the lower to middle 70s. Based on the latest SPC mesoanalysis, there is about 1500-2500 J/kg of MLCAPE available with minimal CIN in place. This should allow for some strong updrafts as storms continue to develop along and ahead of the front. In addition, deep layer shear is also sufficient for some rotation which will help increase severe chances across the area. The main risks for any severe weather will be large hail and possible wind gusts for any updrafts rooted in the boundary layer ahead of the cold front. Flow in the 5-7kft range is weak on the latest Vad-Wind Profiles which should help limit tornadic potential, but an isolated tornado is possible, especially along the front. In addition to the severe chances, heavy rainfall will also be possible with precipitable water values up to 1.7" which is quite high for this time of year. One storm out in Val Verde County has already put down about 2 inches of rain in an hour. In addition, activity is developing closer to the I35 corridor. With a slower moving front eventually catching up to the warm-sector precip some mergers could lead to more efficient rainfall producers. This could lead to the Flash Flood Warnings later today and tonight. Issued a Flash Flood Watch for the Central CWA where the threat of flash flooding would be highest. WPC has upgraded most of the area to a slight risk on the latest Excessive Rain Outlook and this seems reasonable. The Coastal Plains counties are still in drought and therefore, the threat of flash flooding is lower. Things behind the front tonight should be drier than previously thought once the front does move south of the region. Lowered the PoPs a little for the overnight period, but not quite as low as the new guidance suggests. The main story by morning will be the colder air behind the front. Currently temperatures, are in the 40s north of our CWA and we should see temps in the 50s and possibly 40s rather quickly behind the front. Lowered the temperatures for tonight a bit further with lows in the morning in the 40s/50s. A cool day is expected on Saturday with highs only reaching the 50s for most locations. Another disturbance embedded in the westerly flow aloft will spark off additional showers and storms behind the front. This activity is not expected to be severe, but will bring another round of decent rainfall to the area. There could be some additional issues of low-lying areas with possible rises in creeks, streams, and rivers. Rainfall chances will then diminish again Saturday night with lows back in the 40s/50s. && .LONG TERM (Sunday through Friday)... Periods of rain are expected through mid-week, but not everyone is likely to receive rain each day. Highs will warm back up into the 80s for most locations on Tuesday. The drying trend will be short-lived with rain chances increasing once again on Thursday and Friday as the next storm system moves into the area. && .PRELIMINARY POINT TEMPS/POPS...
