| Area Forecast Discussion National Weather Service Corpus Christi TX 634am CDT Wednesday July 22 2026 Issued at 124am CDT Wednesday July 22 2026 A mid-level ridge located over the central Great Plains continues to be the predominant feature driving hot and relatively dry conditions across the CWA (County Warning Area) on Wednesday into Thursday morning. Subsidence aloft will promote highs in the upper-90s along the Coastal Bend, and up to 100-105 degF elsewhere. These highs coupled with dewpoints in the 60s and 70s will promote heat indices ranging from 105-113 degF, introducing a moderate to major (levels 2/3-4) HeatRisk. A Heat Advisory is in effect Wednesday throughout much of the CWA. The forecast changes very little on Thursday, so an additional Heat Advisory is likely. Tropical Storm Bertha continues to move slowly westward across the northern Gulf. The cyclone remains heavily sheared, and the low level center is exposed. Bertha is now expected to gradually weaken as vertical shear increases and land interaction becomes likely. The storm is forecast to pass over or just south of Coastal Louisiana and arrive in the vicinity of East Texas on Thursday. The aforementioned vertical shear will accentuate the northeast to southwest tilt of TS Bertha's vortex. As a consequence, PVA and deep moisture associated with TS Bertha may be in place over the CWA on Thursday evening into the early overnight hours. Due to this environment, isolated to scattered showers and thunderstorms (35- 55%) are possible. While TS Bertha will likely remain north and lose strength, higher surf and an elevated risk of rip currents is generally expected this weekend. Marine Issued at 124am CDT Wednesday July 22 2026 A gentle to moderate (BF 3-4) southerly flow will persist through the week, with periods of Fresh (BF-5) flow at times from Port of Aransas south over the nearshore waters. As Bertha continues to move slowly westward increasing swell and building seas accompanied by isolated to scattered rain chances toward late this week can generally be expected. Will continue monitoring impacts from the storm as uncertainty remains significant this far out. Forecast details will continue to be refined as additional observational data becomes available. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX... Heat Advisory from noon today to 8pm CDT this evening for TXZ229>234-239>244-246-247-347. GM...None. |
