099 FXUS64 KCRP 241752 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 1252 PM CDT Fri May 24 2024 ...New AVIATION... .SHORT TERM... (Today through Saturday) Issued at 335 AM CDT Fri May 24 2024 Key Messages: Dangerous Heat Continues Quasi-zonal flow will continue today as an upper-level ridge begins to build tonight into tomorrow. Well above-normal temperatures and dew points are expected to continue and promote miserable heat indices across South Texas. With heat index values expected to reach the 117-119 degree range this afternoon, an Excessive Heat Warning will be in effect. As daytime highs tomorrow continue to trend to be a couple degrees warmer than today, there is a high chance for the issuance of another Excessive Heat Warning for tomorrow. Although confidence is high for another Excessive Heat Warning for tomorrow, will opt to not issue at this time to allow the current one to expire. Major to extreme risk of heat-related impacts will continue today with more widespread extreme risks tomorrow. 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 only around 6 to 7 seconds and swell heights of 3 to 4 feet, water levels 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... (Saturday night through next Thursday) Issued at 335 AM CDT Fri May 24 2024 Key Messages: - Major to extreme heat-related impacts continue through Monday. Largely mid-level ridging pattern persist into early next week. Continued hot and humid conditions are anticipated with high temperatures between 105 and 110 over the Brush Country and in the 90s and lower 100s east. Surface moisture holds strong with dewpoints in the 70s, resulting in elevated heat index values. Heat risk levels remain major to extreme. Some relief comes early next week as the ridge flattens a bit and we start to get some shortwaves punching through it. This should drop our temperatures down a notch as well as provide at least a little more cloud cover. 850 temps that will be flirting with 30C for the weekend also drop back a few degrees. We`ll still be hot - just not as hot. High temperatures will be more like 100-105 degrees west and in the mid and upper 90s east. We`ll even have some low chance PoPs in the forecast each day with the shortwaves. A weak front may even try to push into the area Tuesday. If it can push in at all, it likely does not make it all the way through. && .AVIATION... (18Z TAFS) Issued at 1223 PM CDT Fri May 24 2024 VFR ceilings are currently in place across all TAF sites with MVFR visibilities in select terminals due to lingering haze. VFR ceilings should continue through the reminder of the afternoon before transitioning to a mix of VFR and MVFR by the evening hours. Overnight, mostly MVFR conditions across South Texas with a couple TEMPO groups for ALI and VCT for brief periods of IFR visibilities and ceilings, respectively. By late morning, VFR ceilings should return with haze continuing to reduce visibilities across several terminals. Winds will be gusty once again through evening, especially for the eastern sites, before dropping down by the early overnight hours. && .MARINE... Issued at 335 AM CDT Fri May 24 2024 Moderate to occasionally strong onshore flow is expected through Saturday with a low chance for Small Craft Advisory conditions (winds around 20 knots) this afternoon and Saturday, mainly across the bays and nearshore waters south of Port Aransas. Seas are expected to remain around 4-5 feet through Saturday. Otherwise, generally moderate onshore flow is expected. For Monday and Tuesday, weak to moderate onshore flow is expected. && .PRELIMINARY POINT TEMPS/POPS...
