| Area Forecast Discussion National Weather Service Corpus Christi TX 108am CDT Thu August 27 2026 Issued at 107am CDT Thu August 27 2026 As the southeastern periphery of the mid/upper-level high pressure starts filling in, this will allow upper-level disturbances to dive south across Texas this afternoon and evening. CAMs are in agreement that this elevated convection will start in south-central Texas and move south through the evening, approaching the Hwy 59 corridor. As this precipitation will be elevated in nature, virga and evaporative cooling will allow for some gusty and erratic outflows with the strongest storms, but this will be isolated. Where the CAMs do struggle is how far south any of these showers/storms make it toward the Middle Texas coast after 7 PM. For now, I have introduced some 15-25% Probability of Precipitation south of Hwy 59 after sunset, but the general trend is for any shower activity to start becoming more isolated in nature and on a waning phase. Additional shower activity will restart closer to the I-10 corridor on Friday afternoon/evening, but that is where CAMs come into a bit more of disagreement as to the initiation and coverage. There is greater confidence in shower activity in the Victoria Crossroads from any remnant boundary and seabreeze activity. Saturday is more seabreeze-rainfall dominant, but nothing to atypical from your popcorn storm coverage/rainfall. In the absence of any rainfall (or even worse, with any short- duration/light accumulation followed by copious sunshine), the HeatRisk brought by increased moisture will reach major to extreme levels. Continue to practice heat safety and remember: hydrate, hydrate, hydrate! Marine Issued at 107am CDT Thu August 27 2026 Expect daily gentle to moderate southeasterly winds (BF 3-4) with 1- 2 ft seas through mid-week. Rain chances (20-40%) return on Friday and Saturday generally north of Port Aransas. Fire Weather Issued at 107am CDT Thu August 27 2026 Minimum relative humidity values will drop to as low as 20-25% this afternoon across the Brush Country. With the Energy Release Component forecast to hover in the 70th-89th percentile, the fire risk will remain elevated, but weak winds in the afternoons will limit the necessity for a fire headline. Additionally, afternoon and evening rainfall chances tonight will bring low-end chances for a wetting rain, though this will be isolated to the northern Brush Country. Similar conditions will continue through the weekend with seabreeze bringing isolated rain chances. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
