629 FXUS64 KEWX 190525 AAA AFDEWX Area Forecast Discussion...UPDATED National Weather Service Austin/San Antonio TX 1225 AM CDT Thu Sep 19 2024 ...New AVIATION... .SHORT TERM... (Tonight through Thursday night) Issued at 152 PM CDT Wed Sep 18 2024 An upper level ridge continues to reside over the southern plains this afternoon. The low level pressure field has become somewhat ill defined. The flow, while generally from the southern half of the compass, is a bit erratic over South-Central Texas. A warm, moist airmass remains in place. Temperatures and dewpoints are 0-5 degrees warmer than 24 hours ago. The upper ridge will strengthen during the short term period. The low level flow will become better established from the southeast tonight and continue through Thursday night. Subsident flow from the upper ridge will keep the weather dry through the period. The above normal temperatures will also continue. Lows both tonight and tomorrow night will be mostly in the 70s. Some record warm lows will be possible both nights. High temperatures Thursday will be in the 90s. Record highs are 100 and higher. While we do not have any records in the forecast, some places could be within a couple of degrees. && .LONG TERM... (Friday through Wednesday) Issued at 152 PM CDT Wed Sep 18 2024 Basically status quo again today. More of the same hot and dry weather can be expected through the long term period. 500mb ridging will remain in control late week into the weekend. While a trough from the west will approach on Sunday, it will likely remain well north of our region, resulting in a continued dry forecast. This trough may still help to weaken the ridging in place and bring back some weak southwesterly flow by the middle of next week. This could result in some increased rain chances, but for now, chances are quite low and hot and dry weather remains favored in the 6-10 day and 8-14 day CPC temp and precip outlooks for our region. && .AVIATION... (06Z TAFS) Issued at 1216 AM CDT Thu Sep 19 2024 MVFR cigs return to the I-35 sites between 08z and 10z and then last through 15z. For KDRT, MVFR cigs are forecast for the 11z hour and last through 14z. VFR cigs are forecast across all area terminals by 15z with winds out of the southeast 8 to 10 knots with occasional gusts of 12 to 15 knots.
