CPWhat forecasters said that day
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 May 29, 12:36 AM CDT, 5 minutes earlier.
Area forecast discussion, May 29, 12:36 AM CDT, 5 minutes before
Area Forecast Discussion National Weather Service Austin/San Antonio TX 1236 AM CDT Sat May 29 2021 .AVIATION (06Z TAFs)... The earlier complex of strong to severe storms has exited east of the region. Attention turns to additional convection upstream. The first small cluster of TSRA could impact SAT between 06Z-08Z. Some additional isolated SHRAs and TSRAs are also forming between AUS and BMQ moving southeast. Another complex of storms across west Texas is forecast by recent runs of the HRRR to enter to move into the southern Edwards Plateau and Hill Country 08Z-11Z, potentially impacting DRT. It's unclear how far east the complex will make it, however the HRRR indicates SAT could get clipped 11Z-14Z. && .PRELIMINARY POINT TEMPS/POPS...
