Area Forecast Discussion National Weather Service Austin/San Antonio TX 733 PM CDT Sat Aug 27 2022 ...New UPDATE... .UPDATE... Issued at 731 PM CDT Sat Aug 27 2022 Did a quick update on the POP for the next few hours based on current radar and the isolated showers that are persisting past 7 PM. The 20 POP is carried up til 9PM at which time most showers should be dissipated. && .SHORT TERM... (Tonight through Sunday night) Issued at 215 PM CDT Sat Aug 27 2022 Partly cloudy skies are currently prevailing across South-Central Texas this afternoon with light south/southeasterly winds in place. Temperatures are in the upper 80s to middle 90s across the area. Latest visible satellite imagery some areas of congested cumulus clouds across Llano and Burnet Counties with some more smaller towers near Comal and Gonzales County. Have seen a few echoes on area radars associated with this and the threat for isolated to widely scattered showers and perhaps a thunderstorm will continue through the late afternoon hours for mainly the eastern two-thirds of the area. Activity should diminish this evening with the overnight period expected to be dry. Low clouds should impact the central portions of the areas with lows in the 70s. Rain chances will remain confined to the eastern areas once again tomorrow with highs back in the lower to upper 90s for most locations. && .LONG TERM... (Monday through Saturday) Issued at 215 PM CDT Sat Aug 27 2022 Next week will become more unsettled across South-Central Texas with higher daily rain and storm chances compared to this weekend. A col looks to be positioned over the region on Monday as a shear axis shapes up across the western-northwestern Gulf of Mexico. This shear axis offshore helps pump higher moisture levels into the region with the PWATs increasing to 1.8 to 2.2 inches from generally north to south into Monday afternoon. The highest rain chances during Monday afternoon likely favors the coastal plains with lower chances to the west. The combination of persistent above average moisture levels, broad troughing aloft in-between the offshore shear axis and another weak mid to upper level disturbance across west Texas, and a frontal boundary moving into North-Central Texas helps to promote at least medium (40-60%) rain and storm chances for the duration of the long term period. Activity will generally be mesoscale driven, especially along any boundaries, and the details will become ironed out as we get closer in time. Additionally, expect lulls at times in terms of activity. Overall, the week ahead looks to be a good opportunity for more beneficial rain where the GFS and ECMWF ensemble mean guidance across the region show a solid 1 to 2 inches of rain. Convective processes may result in locally heavy rain and gusty winds at times. As the case for most rain events across our region, locally higher amounts will occur in some spots while others may lose out and receive little. Monday will likely trend as the warmest day within the long term as the higher moisture levels just begin to pump into portions of the area while sun will be more prevalent than clouds during Monday afternoon across the western areas. Afternoon highs then lower into the upper 80s to low 90s for majority of the area through mid to late week given more cloud cover and the persistent area wide rain chances. While conditions are to stay humid at night, the overnight lows look to gradually fall as well with mid to upper 60s trending across the Hill Country and the low 70s elsewhere. && .AVIATION... (00Z TAFS) Issued at 636 PM CDT Sat Aug 27 2022 Some pop up showers continue at this hour but all have been avoiding the TAF locations so far. Still an outside small chance of an evening SH getting close to AUS, but have left out of the TAF for now. Focus overnight will shift to the possibility of MVFR at SAT/SSF/AUS. Model guidance is showing formation around dawn and along with persistence have kept it prevailing at SAT/SSF with a tempo ground at AUS. Mentioned just sct low clouds at DRT as it looks like any MVFR should be east of the airport. POP is too small to mention in the Sunday afternoon timeframe but just like today a few pop up SH could ultimately affect AUS/SAT/SSF. && .PRELIMINARY POINT TEMPS/POPS...
