Area Forecast Discussion National Weather Service Corpus Christi TX 1234 PM CDT Mon Aug 29 2022 ...New AVIATION... .UPDATE... Issued at 1003 AM CDT Mon Aug 29 2022 Have tweaked today's forecast to account for latest radar/satellite/MSAS trends. The 12Z CRP sounding showed a moist environment with PWATs at 2.3 inches. Minimal to no CIN and CAPE values around 2300J/kg combined with the deep moisture, surface coastal trough and a disturbance approaching from the east, will be conducive for scattered convection this afternoon, mainly along the sea breeze. Overall forecast for today remains generally the same with only minor adjustments. && .SHORT TERM... (Today through Tuesday) Issued at 406 AM CDT Mon Aug 29 2022 Moisture has been increasing over the coastal region with isolated showers moving inland. GOES image of total precipitable water shows PW values have increased to 2 inches along the coast with higher amounts up to 2.3 inches over the coastal waters. Latest MSAS analysis shows a weak trough axis along the Middle Texas coast with strong surface moisture flux convergence. Satellite imagery also shows a weak mid level trough over the coastal waters. Models show this feature will only slowly move northward, reaching the coast tonight and move inland over the coastal plains on Tuesday. Low level convergence and deeper moisture will be over the northern Coastal Bend into the Victoria Crossroads today, where PoPs will be in the likely category with chance PoPs over the rest of the Coastal Bend into the Brush Country. Activity may diminish before reaching the western Brush Country this afternoon where PoPs will be only slight chance. WPC shows a Marginal risk for excessive rainfall for Calhoun and Victoria Counties today. After lull in convection this evening, the low level convergence zone will develop along the coast overnight. PWs will remain elevated over the coastal region ranging from 2 to 2.2 inches. Expect convection will develop again late tonight and move inland Tuesday morning over the coastal plains. As the mid level short wave trough drifts inland across the coastal plains Tuesday, an upper level low will form over southern New Mexico in the morning and move southward to west of the Big Bend in the afternoon. Weak upper level diffluence will occur along the Rio Grande as the low moves into northern Mexico. Low level convergence will also increase over the Brush Country by the afternoon as sea breeze moves inland. Will show better chances for rain for the Brush Country on Tuesday afternoon. Heat index values will range from 105 to 109 degrees during the afternoon both days for inland areas of the Coastal Bend to the Brush Country. && .LONG TERM... (Tuesday night through next Sunday) Issued at 406 AM CDT Mon Aug 29 2022 -Daily rain chances persist through the week and into the weekend with the potential for locally heavy rainfall at times. The long term starts out with troughing over the eastern CONUS, an upper-level high just offshore from SoCal and a low pressure system over northern MX/far west TX. While South Texas is under the influence of high pressure located in the vicinity of the S. TX/eastern MX border. This high will retrograde further west throughout the period allowing for several disturbances to affect the region. Several shortwave and inverted troughs along with conditionally unstable atmospheric conditions are expected to affect portions of the state during the latter half of the week and into the weekend bringing daily chances of precip with above normal PWAT's (exceeding 75th percentile). By Wednesday, upper to mid-level features combine with a coastal trough and an east/southeasterly flow aloft allowing for PWAT's to climb > 2.0" for most of the CWA, that will result in scattered to numerous storms. WPC has most of our CWA in a Marginal risk for the Excessive Rainfall Outlook. Locally heavy rain will be possible at times and some localized flooding may occur especially if storms train. Scattered to numerous showers and thunderstorms will then continue each day for the remainder of the long term in response to increased moisture and the aforementioned features. We can expect cooler temperatures by the second half of the week due to storm activity and increased cloud cover. By the time Sunday rolls around temperatures across the region will range from the mid 80s for the Coastal Bend to near 90 for the Brush Country. Heat indices for Wednesday will be near 105 degree mark along portions of South Texas and as temperatures cool, expecting the majority of the region to stay at or below 100 degrees by the time the weekend rolls around. Finally, NHC is monitoring 4 areas for potential tropical development including one area in the southwestern Gulf. It's too early to tell if any of these may turn into something or any effects they may have for South Texas. But now is a good time to review your hurricane plans. && .AVIATION... (18Z TAFS) Issued at 1224 PM CDT Mon Aug 29 2022 Brief periods of MVFR conditions will be possible this afternoon due to scattered showers and thunderstorms.The best chance for thunderstorms this afternoon will be from ALI to VCT and eastward. COT could also see a few showers later this afternoon as they begin to dissipate. The evening hours should be fairly quiet. Overnight into early Tuesday morning, COT could see additional showers and thunderstorms coming from the northwest. Also, additional convection will be possible Tuesday morning across VCT and CRP then mid morning for ALI for convection coming inland from the coastal waters. Otherwise, VFR conditions will prevail through much of the TAF period. A light southerly wind is expected, but could become variable and gusty with any passing storms. && .MARINE... Issued at 406 AM CDT Mon Aug 29 2022 A moderate onshore flow will continue over the Gulf waters today with SCEC conditions. Scattered to numerous showers and scattered thunderstorms will move north today with a weak upper level disturbance. A weak to moderate onshore flow is expected tonight and Tuesday. After a brief decrease in shower activity this evening, scattered showers and thunderstorms will redevelop over the coastal waters overnight tonight and continue through Tuesday. Onshore flow will generally be weak until Friday then becoming weak to moderate. Flow may be moderate at times this weekend into early next week. Scattered showers and thunderstorms can generally be expected each day through the end of the week before increasing in coverage to numerous this weekend. && .PRELIMINARY POINT TEMPS/POPS...
