404 FXUS64 KCRP 250832 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 332 AM CDT Sat May 25 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Sunday) Issued at 329 AM CDT Sat May 25 2024 Key Messages: Dangerous heat continues today, increases tomorrow With the upper-level ridge continuing to build into South Texas, above-normal temperatures are expected to continue today and increase a couple of degrees tomorrow and expand eastward as subsidence increases. Meanwhile, the abundance of surface moisture will continue today with dewpoints a degree or two higher tomorrow. This will continue the major to extreme risk of heat-related impacts across the region. With heat indices expected to be higher (up to 120-122 degrees) and more wide spread tomorrow, there is high confidence that the Excessive Heat Warning will be extended into tomorrow with a high chance of expanding the warning eastward and northward a bit. While on the subject of excessive heat, we have extended the existing Excessive Heat Warning and Heat Advisory into this evening and through tonight as we are once again expecting poor overnight recovery to the heat with widespread heat indices of 80-95 degrees from midnight through sunrise Saturday night. As we are heading into the Memorial Day Holiday weekend, please be sure to practice heat safety. Stay hydrated, take frequent breaks from the sun, avoid strenuous outdoor activities, wear loose and lightweight clothing, recognize the signs of heat stroke and heat exhaustion, and ALWAYS check your vehicle before locking it. Remember your pets too during this warm spell by bringing them inside and providing plenty of water and shelter. Additionally, check local media and government websites for cooling center locations and hours. Despite swell periods gradually decreasing, swell heights will remain elevated around 3-4 ft which will promote water levels to continue to run about a foot above normal, therefore, will maintain the Coastal Flood Advisory for this morning and afternoon. Chances for another Coastal Flood Advisory tomorrow are currently low as swell periods and swell heights are expected to be lower. Furthermore, with winds between 20-25 mph and wave heights of 4 to 5 feet across the local beaches south of Port Aransas, there is a moderate risk of rip currents for today and expected to continue into tomorrow. && .LONG TERM... (Sunday night through next Friday) Issued at 329 AM CDT Sat May 25 2024 Key Messages: - Major to extreme heat related impacts Sunday/Monday - Isolated thunderstorms Monday through Thursday Not much change in the long term forecast. Will continue to see major to extreme heat impact potential for Monday with 850 temps over the area remaining very high (in the upper 20s C). Expect high temperatures 105-110 west with heat index values potentially above 115 for a similar area to where excessive heat warnings are currently in effect for Saturday. As we head deeper into next week, the mid-level ridging subsides south and west some which will allow shortwaves to get closer to South Texas. This will introduce some low end (20%) rain chances daily. Confidence in anything more than that is low with boundaries most likely stalling north of our area. With this pattern change, temps will fall back a notch to more like 100-105 west and in the 90s east. && .AVIATION... (06Z TAFS) Issued at 1021 PM CDT Fri May 24 2024 MVFR CIGs are developing across the Coastal Bend as clouds increase in coverage. Clouds are expected to spread west through the night, leading to MVFR CIGs for LRD and COT generally after 08Z. Haze will also keep VSBYs at MVFR levels at times through tonight into Saturday morning. VFR conditions are expected to resume by mid to late Saturday morning followed by MVFR conditions Saturday evening. SE wind gusts around 25 knots can be expected once again Saturday into Saturday evening. && .MARINE... Issued at 329 AM CDT Sat May 25 2024 Moderate to strong onshore flow is expected through Sunday with a low chance for brief Small Craft Advisory conditions (winds around 20 knots or greater). Seas are expected to remain around 4-5 feet today and tonight before increasing to 5-6 feet Sunday. Generally weak to moderate onshore flow is expected through the upcoming week. && .PRELIMINARY POINT TEMPS/POPS...
