NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at May 19, 5:36 AM CST, 24 minutes earlier.
Area Forecast Discussion National Weather Service Austin/San Antonio TX 636 AM CDT THU MAY 19 2016 .UPDATE...12Z aviation update below. && .AVIATION...Widespread SHRAs and TSTMs will move across South- Central Texas this morning, impacting DRT through 14Z and SAT/AUS through through 16Z. Locally heavy rain, IFR ceilings and visibility and wind gusts in excess of 25KT will be possible in heavier storms. Trailing stratiform rain and embedded SHRAs will be possible through roughly 18Z-20Z at SAT/AUS. IFR to MVFR ceilings will persist through the afternoon. NE to E winds 5-10KT likely to turn north 10-15KT behind the line of storms for a few hours. IFR to LIFR ceilings develop tonight at SAT/AUS. && .PREV DISCUSSION... /ISSUED 355 AM CDT THU MAY 19 2016/ ..Locally Heavy Rainfall Possible Today... SHORT TERM (Today through Friday)... An upper level shortwave trough pushing across the four corners region and into the Southern Plains will aid for locally heavy rainfall development across South Central Texas this morning through the evening hours. At the surface, a stationary frontal boundary across the Coastal Plains is forecast to slightly push to the north just south of Highway 90 and act as the focus for heavy rainfall through the first forecast period. There is a marginal to slight risk of severe thunderstorms across most of South Central Texas Today with stronger storms capable of producing hail up to one inch in diameter and thunderstorm wind gusts of 50 to 60 mph. However, the main weather threat today is expected to be flash flooding as one to three inches of rainfall are anticipated across a large portion of South Central Texas. With the soil already saturated from recent rains the past few days, one to three inches of rainfall will definitely create widespread flash flooding issues. A Flash Flood Watch is in effect through 10 pm cdt tonight. Later this afternoon into the evening hours, weather conditions are forecast to improve from west to east as the upper level short wave opens and pushes into the Central Plains/Mississippi Valley and the frontal boundary pushes back to the Coastal Plains. LONG TERM (Friday Night through Wednesday)... A weak upper level ridging forms over the area on Friday into the upcoming weekend. This will give the area a break with limited precipitation mainly to the Rio Grande. Sunday evening, a cluster of storms may affect the southern Edwards Plateau as they push from the northwest into the area. Isolated to scattered showers and isolated thunderstorms are in the extended forecast through the middle of the week as several short wave disturbances in the southwest flow move through the region. && .PRELIMINARY POINT TEMPS/POPS...
