777 FXUS64 KEWX 101953 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 253 PM CDT Wed Oct 10 2018 .SHORT TERM (Tonight through Thursday Night)... Cooler and drier air is pushing into Central Texas on north winds as dewpoints drop from the upper 60s to low to mid 50s, with afternoon highs today topping out in the mid 70s to near 80. Overnight lows tonight will drop into the mid 50s, with lower 60s expected across the Rio Grande and Coastal Plains. With the cool and dry air in place for Thursday highs should struggle to get out of the 70s. While the majority of South Central Texas will remain dry on Thursday, a few along the Rio Grande could see an isolated shower or thunderstorm. The front that has pushed through the area will sag south and get hung up across eastern Mexico. This, in combination with a subtle disturbance in the southwesterly flow aloft will be enough to spark off this scattered activity. This activity could linger into Thursday night, with lows a few degrees warmer than tonight, but still around seasonal normals. && .LONG TERM (Friday through Wednesday)... Most remain dry on Friday as the upper levels remain zonal with a high pressure to the south of Texas and the remnants of Tropical Storm Sergio moving across northern Mexico. The remnants will continue their trek northeast and move across West and northwest Texas during the day on Saturday. While much of the moisture and lift associated with the weakening trough will remain north of the area its proximity will be enough to increase chances for showers and thunderstorms across all of South Central Texas. The best chances for the day on Saturday will be across the Edwards Plateau and Hill Country. Behind the remnants of Sergio a cold front will push south through the state. The GFS and NAM show the front pushing through Sunday afternoon into the evening hours, while the ECMWF is later with the front having it moving through during the second half of Monday. Regardless the front will continue rain chances across South Central Texas. With the front hanging around chances for rain continue into the middle of the week. With the faster progress the GFS clears out precipitation by Wednesday, while the ECMWF continues a wet forecast into the second half of the work week. The big story with the front, in addition to the rain will be the cooler temperatures. Right now this front looks strong enough to bring 50s and 60s for highs on Monday behind the front, with lows Tuesday morning dropping into the upper 40s across the Hill Country and 50s across the I-35 corridor. Specifics as to just how cold it will get, how much rain we will see, and the possibility of strong storms will depend on the timing of the front, which is still disagreed upon by the front. Will continue to watch the front and its progress south as it is still in days 6 and 7 of the forecast. && .PRELIMINARY POINT TEMPS/POPS...
