| Area Forecast Discussion National Weather Service Corpus Christi TX 338am CDT Fri September 29 2023 ...New SHORT TERM, LONG TER Marine .SHORT TERM... (Today through Saturday) Issued at 335am CDT Fri September 29 2023 Key Messages: - Increasing chances for isolated to scattered showers and thunderstorms mainly near the coast. - Heat Indices 105-109 along the Coastal Bend - Patchy fog possible Saturday morning along the Victoria Crossroads/Coastal Plains Ridging over the plains will progress eastward over the Mississippi River Valley then stall due to a blocking low just off the Atlantic Coast. An inverted trough in the southwestern Gulf will help to increase moisture this weekend and increase storm shower and thunderstorm chances for Saturday with PWAT's (Precipitable Waters) forecast to increase to around 1.90". For tomorrow morning, there's around a 20% chance for Patchy fog across the Victoria Crossroads down the Coastal Plains for a few hours near sunrise. Daytime highs today and tomorrow will range in the 90s with Heat Indices 105-109 degrees along the southern portion of the Coastal Bend. Overnight lows tonight and tomorrow night will range in the 70- 80s. Increasing tidal levels and a weak to moderate flow with an easterly component will increase the risk for minor coastal flooding as we head into the weekend. Not confident enough at this point to issue an advisory but will continue to monitor beach conditions. Long Term (Saturday night through next Thursday) Issued at 335am CDT Fri September 29 2023 Key Messages: - Minor coastal flooding will be possible early next week - Good rain chances are expected through the long term A weak upper level ridge will move into the northwest Gulf of Mexico Saturday night into Sunday as a strong upper trough moves into the western United States. Models show a persistent moist easterly flow into the coastal waters and coastal plains for early next week. The ensembles show precipitable water values ranging from 1.7 to 2.0 inches from west to east Sunday through Tuesday. These values are above normal for this time of year. Expect scattered convection will occur over the coastal waters at night into early morning and move inland during the day from Saturday night through Tuesday. The upper trough will move into the Rockies by Tuesday and into the plains on Wednesday. If the upper trough continues to progress to the east by Thursday, the pattern would be favorable for a front to reach the area by Thursday. But the deterministic models show differences with the upper trough as it moves out of the plains. The ensembles show some differences as well. GEFS shows the progressive trough with drying behind the front by Thursday. But the ECENS/CAN ensembles keep high moisture in place into Thursday with ensemble mean values of PW around 2 inches. With the upper trough approaching Wednesday and the front moving into the region Thursday, will lean toward the wetter scenario and continue the good rain chances into Thursday. With persistent easterly flow along with being near the time of the full moon, minor coastal flooding will be possible at high tide early next week. P-ETSS continues to forecast tides reaching 2 feet MSL at Aransas Pass during the afternoons Sunday and Monday. Marine Issued at 335am CDT Fri September 29 2023 A generally weak northeast flow will strengthen to weak to moderate and shift eastward this afternoon. Isolated to scattered showers and thunderstorms today will increase in coverage tomorrow over the waters. A generally weak to moderate easterly flow will occur Saturday night through Tuesday night with occasional periods of moderate flow over the Gulf waters at night. Scattered showers and thunderstorms are expected daily from Sunday through Tuesday. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
