Area Forecast Discussion National Weather Service Corpus Christi TX Issued by National Weather Service Austin/San Antonio TX 1139am CDT Wednesday Jun 18 2025 Issued at 1235am CDT Wednesday Jun 18 2025 Not much of a change from the previous forecast package with ridging generally maintaining control aloft through the period. Hot conditions will continue today leading to a moderate to major risk of experiencing heat related impacts with HI values climbing to around 105-114 across the area. Rain chances will remain less than 10% today, but will begin to increase on Thursday as deeper moisture pools into the area. Precipitation chances will remain low to moderate through the weekend (20-40%), before increasing to near 50-60% early next week as a wave is forecast to skirt under the mid-level ridge and track into our area. There is still plenty of uncertainty with this feature, and changes to the forecast are likely in following packages, but for now have trended with higher Probability of Precipitation Tue-Wednesday next week. As rain chances increase later in the week, and with an increased cloud coverage, the heat risk will lower to minor to moderate levels. Aside from that, expect the breezy S to SE winds from today to begin to diminish overnight tonight. With a persistent moderate SE flow over the offshore waters and swell periods around 7-8 seconds at 1-2 ft, have increased the risk of rip currents to Moderate levels for today and tonight. Conditions are forecast to improve over the surf zone by Thursday with a lighter onshore flow in place and a minor risk of rip currents. Marine Issued at 1235am CDT Wednesday Jun 18 2025 A moderate to fresh breeze (BF 4-5) will continue today and tonight before becoming mainly moderate (BF 4) Thursday through the weekend. Low to medium (30-60%) rain chances can be expected each day from Thursday through early next week, especially across the Gulf waters.
