| Area Forecast Discussion National Weather Service Corpus Christi TX 638am CDT Wednesday September 16 2026 Issued at 1220am CDT Wednesday September 16 2026 As moisture continues to gradually advect into the region, heat index values will remain high Wednesday with a high to moderate risk of heat-related impacts. Some relief to the heat will come later this week as rain chances continue to look favorable, mainly for Wednesday night and Thursday. As mentioned in the previous discussion, capped the Max Probability of Precipitation from the NBM to be more in line with the previous forecast due to uncertainty. As models have been consistent with rain chances for Thursday, it's still a little cloudy for how widespread they will be as well as the potential intensities. While rain chances will be medium to high across the eastern half of South Texas Thursday, the chances for the western half will generally remain low with chances less than 40%. Models show a long easterly fetch developing across the northern Gulf waters this week which may help push water farther up the beaches. Will continue to monitor trends for slightly higher than normal tides and/or an increased rip current risk. At this time, minor coastal flooding is not anticipated but will continue to be monitored. More heat safety information can be found at weather.gov/heat Marine Issued at 1220am CDT Wednesday September 16 2026 A moderate to gentle southeast breeze persists tonight with 2-3 ft seas. Winds primarily will be easterly from Thursday across the western Gulf resulting in seas increasing to 3-5 ft and then reducing to 3-4 ft on Friday. Rain chances increase through Friday. Fire Weather Issued at 1220am CDT Wednesday September 16 2026 ERC values will improve to the 50-69th percentile for much of the region and remain at those levels through the end of the week. While ERC values will be decreasing, relative humidity values will be improving with 30-45% Wednesday and above 40% across all of South Texas Thursday into the weekend. Therefore, elevated fire weather conditions are not expected at this time. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
