NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at Jul 9, 9:10 PM CST, 2 hours 35 minutes earlier.
Area Forecast Discussion National Weather Service Austin/San Antonio TX 1010 PM CDT SAT JUL 9 2016 .UPDATE... Have boosted PoPs north of a Fredericksburg to Austin to Giddings line as storms have become better organized. This will likely be a short term trend as the outflow boundary further outruns the storms. Then, they will weaken and dissipate during the overnight hours. && .PREV DISCUSSION... /ISSUED 852 PM CDT SAT JUL 9 2016/ UPDATE... Surface outflow boundary continues to drop south into Central Texas this evening with showers and thunderstorms developing along it. Expect it will move into the Hill Country and South Central Texas in the next couple of hours. Further west, isolated showers and thunderstorms continued over the Edwards Plateau and Serranias del Burro of Mexico. Expect the Burro and Plateau storms to slowly wane. Have reconfigured PoPs and gone only slight chance north of a Langtry to Kerrville to Blanco to Giddings line through around Midnight. By then, increasing stabilization with nighttime will cause the showers and thunderstorms to mostly dissipate. However, will monitor radar trends for any later updates to PoPs. The boundary and an upper level shear axis/speed max rotating around the Subtropical Ridge may develop showers and thunderstorms on Sunday and PoPs may have to be added for that time period. Only other changes were to reestablish trends to the sensible weather grids for tonight due observational trends. PREV DISCUSSION... /ISSUED 654 PM CDT SAT JUL 9 2016/ AVIATION.../00Z TAFS/ The broken line of showers and thunderstorms currently located between DFW and ACT will continue to push south and continue to dissipate over the next few hours. Although the outflow boundary may persist long enough to affect AUS later tonight, storms are not expected to develop along this boundary after sunset. Thus, the I-35 TAF sites should have VFR conditions until they lower to MVFR after 5-6Z with perhaps some light patchy fog at AUS around sunrise. Ceilings should lift to VFR between 14-15Z at these sites as has been the case over the past few days. Isolated storms west-southwest of DRT should dissipate over the next few hours before having a chance to move across the border. Similar to the last few nights, VFR ceilings will lower to MVFR around 2500 feet by 11Z before lifting to VFR around 15Z. Winds will be a bit lighter tomorrow out of the southeast at 10 knots for DRT, while being a bit more southerly at 10-15 knots for the I-35 TAF sites with gusts generally remaining below 20 knots. PREV DISCUSSION... /ISSUED 255 PM CDT SAT JUL 9 2016/ SHORT TERM (Tonight through Sunday Night)... Satellite loops and derived wind plots suggest a solid mid level shear axis extending from near Big Bend to Fort Worth. Isolated to scattered convection was forming in this area this morning, and model projections are for this area to drift south to southwest tonight into Sunday. Some models generate QPF over the I-35 corridor and there are wide variations in the run-to-run fields among the rapid refresh models. SPC mesoanalysis indicates higher QPF fields over N-Cntrl TX and near DRT with weaker Pwat values around 1.5 near the I-35 corridor. Thus expect some isolated short-lived convection to possibly develop as far south as the Balcones Escarpment this evening and possibly a scattered cluster of convection where a higher consensus of enhanced rain chances over the Southern Edwards Plateau and Nrn Rio Grande Plains. Given the high temps around 100 in this area, some gusty winds over 40 mph could develop, especially if multicell clusters develop. High heat indices to around 107 continue over the Coastal Prairies this afternoon with a downward trend noted from recent days over most areas. Models show the mid-level shear axis south of the area by late Sunday morning with decreasing Pwat values and slightly lower surface dew point temps by midday. Thus Heat indices should continue to ease up on Sunday. LONG TERM (Monday through Saturday)... High pressure aloft strengthens eastward over N TX late Sunday into Monday and resumes a drier forecast. An inverted mid-level trough builds over the Rio Grande Plains Tuesday, enhancing onshore flow while the upper ridge remains dominant. A few showers and storms are depicted over far SE counties during the day Wednesday where deep layer onshore winds develop, but the ridge presence will minimize significant rain chances while bringing heat indices toward advisory levels again. A deeper onshore fetch of winds develop late next week, leading to a slight cooling trend, but no significant boost in rain chances. && .PRELIMINARY POINT TEMPS/POPS...
