750 FXUS64 KEWX 092341 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 641 PM CDT Tue Oct 9 2018 .AVIATION... Easterly wake low waves from the MCS that moved through earlier have generated enough lift for partly to mostly cloudy skies along and east of I-35, along with a few light showers over the southeast coastal plains. The showers should dissipate in the next hour or so, and the clouds clear by midnight, as the waves dampen and cease with the MCS moving east. The 1/4 to 2 inches of rain many places received this afternoon and rapid clearing/drying above the boundary layer should set up patchy fog late, although visibility should remain AOA 3 miles with light north-northwest downslope winds. The I-35 TAFs show the backing winds and fog development, but remain VFR thorugh the night. KDRT should also remain VFR through the night. Look for all sites to be VFR with light north-northeast winds on Wednesday. && .PREV DISCUSSION... /ISSUED 244 PM CDT Tue Oct 9 2018/ SHORT TERM (Tonight through Wednesday Night)... A line of showers and thunderstorms continues to push east with the back edge now nearing the I35 corridor. Ahead of the line a complex of showers and storms developed across the Coastal Plains and continues to push north across our eastern Counties. Overall, the threat of widespread Flash Flooding is low as the line has become more broken and has decent forward progress. Brief heavy rain with totals up to 1-2" will remain possible and could see some Flood Advisories needed from the heavier cells. We haven't seen any severe storms since the morning hours, but the chances are non-zero and some intensification remains possible. The eastern cells are currently strong with 30+ knot winds being reported. Rainfall will continue to push east in the late afternoon and evening hours and will break PoPs into 3-6 hour increments for the tonight forecast to properly show the trend of rain ending from west to east. Behind the rainfall, north winds and cooler/drier air will filter into the area. Lows tonight could reach the upper 50s for the Hill Country with 60s elsewhere. Highs tomorrow will remain in the 80s with dry weather continuing. Lows Wednesday night will be in the 50s and 60s across the area. LONG TERM (Thursday through Tuesday)... The beginning of the long-term forecast will remain mostly dry with the cooler temperatures continuing. Highs Thursday and Friday will remain in the 80s with lows in the 50s and 60s. Rain chances return to mainly the northwest CWA on Saturday as the remnants of Hurricane Sergio in the Pacific races across West Texas. Behind it a cold front is progged to move through the area Saturday night or Sunday with additional rain chances lasting through Monday night. Much cooler temperatures are possible behind this front with highs Monday currently forecasted to be in the 60s across the area with lows Tuesday morning in the 40s and 50s. It will be a welcome to Fall weather if this comes to fruition. && .PRELIMINARY POINT TEMPS/POPS...
