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 Jun 4, 6:32 PM CDT, 3 hours 23 minutes earlier.
Area forecast discussion, Jun 4, 6:32 PM CDT, 3 hours 23 minutes before
Area Forecast Discussion...UPDATED National Weather Service Austin/San Antonio TX 632 PM CDT Sun Jun 4 2017 .AVIATION.../00Z Update/ Scattered convection continues across the region moving E/SE around the western side of the upper level low. This trend will continue with numerous outflow boundaries creating variable winds and allowing for new convection to develop. Should see a decrease after sunset in the coverage and intensity of convection, but a repeat is expected in NW flow on Monday. With timing and location issues will go with vicinity for the start and ending time frame of this forecast. Later forecast can pinpoint the windshifts and onset of convection. Currently VFR across the area and expect this trend to continue thru the forecast period. Could see a period of MVFR cigs after 09Z and thru 15Z, but for now maintained VFR. Winds will be variable, but mostly northerly around 5 knots tonight and N/NW 7-10 knots after 15Z. Winds in or near any convection will be much stronger. && .PREV DISCUSSION... /ISSUED 238 PM CDT Sun Jun 4 2017/ SHORT TERM (Tonight through Monday Night)... The ITCZ-like atmosphere continues across TX/LA today with scattered showers and thunderstorms, some with intense downpours and gusty winds, and outflow boundaries and differential heating providing the lift for new convection. While overall PoPs are moderate for any given location, driving 100 miles around the area would likely cause drivers to turn on the wipers at least once. More important is drivers Turn Around and Don't Drown if approaching any location where water is rushing across the road. The storms should wane this evening with the loss of diurnal heating, but like last night, the Low Level Jet might support isolated storms around throughout the night. LONG TERM (Tuesday through Sunday)... The longwave trough that has locked-in a seasonally-cool and wet period the last few days will begin to move east and get absorbed in a large trough centered over the Great Lakes. This will result in reduced chances for rain areawide on Monday, and rain chances only for the coastal plains east of I-35 on Tuesday. Weak subtropical ridging will bring a return to dry weather and seasonal temperatures from Wednesday onward, but the longer ranges of the GFS and ECMWF indicate the ridge will not become established over the Desert Southwest as it usually does this time of year. In fact, a high amplitude trough-ridge-trough pattern will progress across the northern two-thirds of the U.S. during the week of June 11th -- with a roller coaster of conditions at many locations. South Central Texas is on the southern periphery of this pattern, so the sensible weather for us should be near normal temperatures with only isolated afternoon showers and thunderstorms each day. && .PRELIMINARY POINT TEMPS/POPS...
