| Area Forecast Discussion National Weather Service Corpus Christi TX 551am CDT Wednesday August 26 2026 Issued at 129am CDT Wednesday August 26 2026 The dominant mid/upper-level high pressure continues to bring 100 degree high temperatures to much of South Texas (with 90s along the coastal zones). Coupled with dewpoint temperatures still remaining in the 70s in the afternoons east of a line from Cross to Benavides, the HeatRisk is forecast to climb back to mostly Major (level 3 of 4) with heat indices climbing to as high as 114F. For this reason, a Heat Advisory has been issued these zones from noon to 7pm today. This heat dome slides ever so slightly westward Thursday and Friday, resulting in upper-level winds to come out of the northwest/north allowing some disturbances to push into south-central Texas. While the majority of CAMs have some form of composite reflectivity moving through the northern Brush Country Thursday evening, any shower that moves in from the I-10 corridor will be elevated in nature leading to virga as any storms moves toward the Hwy 59 corridor. That said, storms forming from the collision of the sea-breeze may be more efficient at dropping a few more raindrops (more so for the Victoria Crossroads as their PWATs (Precipitable Waters) are forecast to be between 2.0-2.2"). Friday's rain chances (20-30% in the Victoria Crossroads and less so further south along the Coastal Bend) are a bit lower in confidence among the global models. In the absence any rain on Thursday and Friday, higher dewpoints would increase the HeatRisk and would warrant further consideration of any heat-related headlines. Moving further into the forecast period, low end rain chances (<20%) associated with the seabreeze return as the heat dome slides east and weakens as it does so. Summer in Texas is still in full force. Marine Issued at 129am CDT Wednesday August 26 2026 A light to moderate (BF 2-4) onshore breeze will continue through the week, with occasional fresh (BF 5) breezes possible during the late afternoon/evening hours, especially south of Port Aransas. Low- end rain chances return north of Port Aransas Thursday/Friday, but will be isolated. Fire Weather Issued at 129am CDT Wednesday August 26 2026 ERC values continue to hover near the 90th across much of South Texas (with the exception of the coastal plains). Humidity values will continue to be low, with minimum RH values below 34% over the Coastal Plains and as low as 20-25% across the Brush Country. While winds will remain light in the morning, afternoon winds combined with low humidity will increase the fire risk to elevated conditions, leading to a Fire Danger Statement for the Brush Country this afternoon. Low-end chances for precipitation (20-30%) return to the northern Brush Country and Victoria Crossroads Thursday night, though chances for a wetting rain remain low. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX... Heat Advisory from noon today to 7pm CDT this evening for TXZ230>234-240>247-342>344-346-347. GM...None. |
