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 Austin/San Antonio, TX wrote its last area forecast discussion before the first event at May 7, 7:22 PM CST, 48 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Austin/San Antonio TX 822 PM CDT Tue May 7 2019 .UPDATE... Increased PoPs for the next several hours for the I-35 corridor including areas from San Marcos north to Georgetown area. Locally heavy rain is ongoing across the Austin metro area and radar trends suggest for this cluster of storms to move north along I-35 towards the Round Rock/Georgetown area with the next hour or so. This activity is forecast to diminish by 10 PM this evening with isolated showers anticipated over the area overnight. && .PREV DISCUSSION... /ISSUED 644 PM CDT Tue May 7 2019/ AVIATION... Clusters of thunderstorms have developed over the last hour that is only impacting AUS. This activity is expected to wane heading into the late evening hours. I-35 sites look to drop ceilings to IFR conditions around 7-9Z period and DRT staying low-end MVFR. A front that looks to develop convection moves over the region in the early morning hours. Timing of this line is still in question with the CAMs having it moving into the I-35 corridor anywhere from 15-21Z. DRT is not expected to see any convection but should see a wind shift. Another lowering of ceilings for AUS and SAT is expected just beyond the TAF period. PREV DISCUSSION... /ISSUED 248 PM CDT Tue May 7 2019/ SHORT TERM (Tonight through Wednesday Night)... Isolated showers and thunderstorms continue across mainly the eastern two-thirds of the area at the present time. The best lift and subsequent coverage of rainfall is east of our CWA. Latest high-res model guidance does show an uptick in coverage east of I35 later this afternoon as the surface heats a bit more. Overall this activity is not expected to be severe, but some stronger storms can produce brief gusty winds, small hail, and brief heavy rainfall. The focus then shifts out west for later this afternoon and evening. A dry line sits west of Val Verde County and there could be some isolated thunderstorm development on this boundary. Any storms would move east and could impact Val Verde County. The environment across this area is more conducive for stronger to severe storms, and there is a slight risk of severe storms for Val Verde County. A much higher coverage of showers and thunderstorms is expected across Northwest Texas this afternoon and evening where there are significant chances for severe weather. Latest high-res models show this activity eventually congealing into a line of storms overnight as it moves to the east/southeast. Some of the high-res guidance is much quicker with its progression of the line with it entering our northern counties by 7 AM. The activity should then continue progressing east through the morning and early afternoon hours. Some activity could linger into the late afternoon and evening hours. The quicker timing is supported by the ECMWF, but the TTU WRF, NAM, GFS are all a bit later. The timing of the line will have a big determination on the severity and types of severe weather. If the line moves through early, straight line winds and perhaps isolated tornadoes will be possible. If the line is a bit later then large hail becomes a big risk as CAPE values in the afternoon could be over 4000 J/kg. In addition to the risk of severe weather, locally heavy rain is possible, especially if we get a solid line of convection into the area. The latest Day 2 Outlook has most of the area in a slight risk and areas north of a Blanco to San Marcos to Giddings line in an enhanced risk. Rainfall amounts will average 1-2 inches with higher amounts in the northern CWA where the activity is expected to be highest. With grounds remaining moist after previous rainfall, it won't take much to cause some problems in low-lying locations. Will see how things set up this evening and tonight, and future shifts will monitor for any possible headlines. The activity should push mostly east of the area by the late evening hours and will show decreasing PoPs Wednesday night. LONG TERM (Thursday through Tuesday)... A cold front is expected to push into the area by Thursday morning on the backside of the upper trough currently moving through the plains. At the same time, another shortwave trough embedded in southwest flow aloft will approach the area. These two features will provide a scenario for some widespread rainfall across the area. If storms remain rooted in the boundary layer ahead of the front, some severe storms would be possible. However, latest guidance shows most activity behind the boundary which would be elevated. There could be a chance of some hail out of this scenario. SPC has most of the area outside of the Hill Country in a marginal risk and this seems reasonable. Rainfall intensity behind the front is expected to be highest late Thursday afternoon or Thursday night depending on the exact timing of the trough. Rainfall totals could reach another 1-3 inches with isolated higher amounts. The higher amounts look to be across the eastern CWA, where there is a slight and moderate risk of excessive rainfall from WPC. The front is expected to push well south of us on Friday limiting the threat of continued heavy rainfall Friday. Temperatures Friday will be quite cool, in the 60s. However, the bad news is another shortwave trough is expected to move into the southern plains on Saturday. The ECMWF develops a surface low to the east of our area, which drags the front back north. These features will bring another chance of heavy rainfall to the area. Still plenty of time to watch this system, but with systems tomorrow, Thursday night, and Saturday there is the potential for significant rains in our CWA. The latest 7 day WPC rainfall forecast has 6"+ in our eastern counties. We are stressing flood safety this week and having a plan when potential Flash Flood Warnings are issued. Should see a break in systems for Sunday, and will carry just 10-20 PoPs Saturday night and Sunday. Chances of rain will increase again Monday and Tuesday as yet another system moves into the region. && .PRELIMINARY POINT TEMPS/POPS...
