Area Forecast Discussion National Weather Service Corpus Christi TX 317pm CDT Thu August 6 2020 Short Term - Tonight Through Friday Night High pressure centered over W TX this afternoon is forecast to slowly move east tonight through Friday. A weak embedded short wave will move south to southeast around the outer periphery of the high which will bring slightly deeper moisture into eastern portions of S TX late tonight/Fri. Models prog a swath of PWATs (Precipitable Waters) around 1.7 inches across the eastern CWA Friday. Sufficient moisture and instability will be in place for isolated convection along the sea breeze Friday. The convection will wane by Friday evening with the loss of daytime heating. Isolated convection is forecast to redevelop over the coastal waters and along the coast late Friday night due to low level moisture convergence. With the slight increase in moisture, heat indices are expected to be 105 to 109 Friday afternoon across portions of S TX. Mild temperatures are expected tonight and Friday night. Some models prog light patchy fog to develop across the inland Coastal Plains early Fri morning. Will not mention in the forecast at this time due to it being light and brief. Long Term - Saturday through Thursday As the upper level high pressure gradually moves westward, a weak trough sets up over the Central Plains. This will allow moisture to increase across the area this weekend and into early next week. With the increased moisture, isolated to scattered showers and thunderstorms will be possible this weekend, becoming more isolated by early next week, mainly across the Coastal Bend and Victoria Crossroads. Next week we will be under the influence of the eastern edge of high pressure to our west and a weak upper level trough to our north. Some models show the trough axis dipping further south at times, along with plumes of moisture across the area. Therefore, maintained Probability of Precipitation in the 20s for each afternoon next week as showers and thunderstorms will be possible, especially with the seabreeze interactions. Heat indices will range between 105-109 for the majority of the CWA with some areas possibly reaching 110 degrees. Marine A light to moderate onshore flow will continue this weekend into next week, becoming more moderate each afternoon. Scattered showers and thunderstorms will be possible over the weekend across the bays and offshore waters, becoming more isolated each afternoon next week. Seas will be around 2 to 3 feet this weekend and into next week, occasionally reaching 4 feet across the offshore waters. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX...None.
