NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at May 13, 2:39 PM CST, 2 hours 27 minutes earlier.
Area Forecast Discussion National Weather Service Austin/San Antonio TX 339 PM CDT FRI MAY 13 2016 .SHORT TERM (Tonight through Saturday Night)... Late afternoon surface observations show a stationary front across the coastal plains into the Rio Grande plains near Eagle Pass. Otherwise, surface observations show a moist axis in place across west central TX into the Hill Country. For the remainder of this afternoon into the early evening, convection will be favored from just north of the frontal boundary into the Hill Country along the above mentioned moist axis. We can't completely rule out a strong storm or two, but most activity will likely remain sub-severe. Once we loose our daytime heating, this activity is expected to decrease. The models do show some overnight/early morning activity dropping southward from the panhandle/Texas south plains. However, we are not confident this activity will make it into our region. With this in mind, we'll go with a dry forecast for the late evening and overnight hours. On Saturday, a weak outflow boundary moving down from the north combined with a cold front moving down from north Texas will bring additional rainfall chances to south central Texas. The flow aloft will be rather weak, but again we can't completely rule out a strong storm or two in the afternoon and evening hours. && .LONG TERM (Sunday through Friday)... On Sunday, the flow aloft will begin to increase and slowly transition from northwesterly to southwesterly as an upper level trough drops across the western U.S. Meanwhile, the above mentioned cold front may continue to drop into south central Texas. Just how far south the front drops will largely depend on the amount of convection along and behind the boundary. For now it appears the front will not make much more progress than roughly the Highway 71 corridor on Sunday. The medium range models both show an increase in mid-level shortwave activity on Sunday. With this and a front in the area, we have increased rain chances slightly. The forecast continues to look interesting Sunday night into Monday morning as we could see an MCS move across our region. At this time, it appears areas along and west of I-10 stand a better shot at seeing this activity. This definitely will be monitored and for now we have increased rain chances slightly. For the remainder of the forecast, the flow aloft should remain rather active across Texas. This should continue to provide a good chance for showers and thunderstorms across our region. The medium range models disagree in showing a cold front moving into the region Tuesday afternoon. For now, we'll need to monitor the weather on Tuesday as this could provide another good chance for strong to severe thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
