Area Forecast Discussion National Weather Service Austin/San Antonio TX 334 AM CDT Sun Jun 30 2019 .SHORT TERM (Today through Monday)... A complex of storms that originated over North Texas yesterday evening has worked all the way south into the San Antonio metro area. A few strong gusts occurring in some segments of the complex in addition to small hail. Also, a quick 1-1.5" of rain has been occurring in about 30 minutes, with some isolated pockets in excess of 2" estimated over portions of Guadalupe and Kerr counties. Fortunately with the speed of the complex significant/widespread flash flooding is not expected, however a few low water crossings could have some issues across Kerr and Bexar counties over the next hour or two. Models have struggled with this complex. PoPs through the early morning hours are entirely based on radar trends, with categorical PoPs for southern areas being affected by the complex. The main complex should continue south of San Antonio by day break, with trailing stratiform rain possible through the morning. Scattered upstream convection has developed back across Central Texas, and could also work into portions of the northern CWA through the morning, wrapping around the northwest side of the mid level low retrograding west. Despite being worked over by this system early this morning, there should be recovery later in the afternoon and early evening to allow for additional develop of showers and storms. Difficult to pinpoint where re-development could occur in the afternoon and have kept PoPs in the chance/scattered range for this time period across much of the CWA. A chance of scattered showers and storms will continue into Monday as the retrograding mid and upper level low becomes elongated north to south across the CWA. && .LONG TERM (Monday Night through Saturday)... Slightly drier mid level air works into the region Monday night into Tuesday morning. Then precipitable water values increase Tuesday afternoon through Wednesday to around 1.8-2.1", as a surge of tropical moisture from the Gulf of Mexico works into portions of the region. With the upper level trough/weakness lingering over the region during this time expect periods of scattered showers and storms, favoring eastern areas Tuesday and further west on Wednesday. A drying trend is forecast to take place Thursday into Friday, with an upper level ridge building in from the east Friday through the weekend. && .PRELIMINARY POINT TEMPS/POPS...
