582 FXUS64 KCRP 121802 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 102 PM CDT Mon Aug 12 2024 ...New AVIATION... .SHORT TERM... (Today through Tuesday) Issued at 233 AM CDT Mon Aug 12 2024 Key Messages: - Heat Advisory in effect for portions of the Coastal Bend this afternoon. - Low to medium rain/thunderstorm chances east today and Tuesday. A mid to upper level inverted trough will drift westward into the area through the short-term period riding on the southern periphery of the high as this one shifts eastward. Deeper tropical moisture will be arriving through the period as well with PWATs increasing to around 2.0". This moisture increase in combination with the passing disturbance aloft will bring a low to medium chance for showers and thunderstorms (PoPs 20-40%) today and Tuesday. A few showers have already developed over the coastal waters early this morning, and the activity is forecast to drift inland through the day, being enhanced along the seabreeze in the afternoon hours. Rain chances will taper off overnight tonight, before returning Tuesday morning. Aside from the rain and storm chances, the main headlines for today will be the potential for dangerous heat conditions. Given moisture is expected to increase across the area today leading to afternoon dewpoints in the mid to upper 70s along the coast and high temperatures in the 90s, a Heat Advisory has been issued. The Advisory for now covers coastal and inland portions of the Coastal Bend, but an expansion farther inland cannot be ruled out depending on how much heating can be achieved today. Overall, heat index values will range between 109-112 over much of the area today, and likely again tomorrow. Additional advisories may be required in later packages. && .LONG TERM... (Tuesday night through next Sunday) Issued at 233 AM CDT Mon Aug 12 2024 Key Messages: - Low chance of showers and storms over the northern Coastal Bend Wednesday - Moderate to major risk of heat-related impacts through the weekend. A low chance for showers and thunderstorms will linger Wednesday afternoon as the seabreeze moves over the Victoria Crossroads/northern Coastal Bend where PWATs are expected to range from 2.0-2.2". By Wednesday night, chances for rain become too low for even a mention in the forecast as the high pressure ridge redevelops over the area. The big concern for the upcoming week and weekend will be heat related impacts. High temperatures will remain in the 90s across the coast to around 105 out west. Heat index values will range from 105- 114 across most of the area, with isolated locations experiencing even higher heat indices. Please continue to use caution. If you must be outdoors, remember to drink plenty of water, take breaks out of the sun, wear sunscreen, and protect yourself and your pets from this heat. Heat stroke is an emergency; call 9-1-1 if you or a loved one are experiencing symptoms. && .AVIATION... (18Z TAFS) Issued at 1258 PM CDT Mon Aug 12 2024 Continuing the VFR conditions across the TAF sites this afternoon. A shower is possible, but the chance for rain showers and thunderstorms will be Tuesday afternoon, mainly near VCT. Otherwise, there is a chance (40-50% <5SM) for VSBY restrictions between 10z-14z at ALI and VCT with the increase in moisture and the mainly clear night. && .MARINE... Issued at 233 AM CDT Mon Aug 12 2024 There is a low to medium 20-40% chance for showers and thunderstorms over the coastal waters today and Tuesday, followed by a low chance 20% on Wednesday offshore. Otherwise, dry conditions are expected through the rest of the week. Weak to moderate south to southeast winds will continue through the week into the upcoming weekend. && .PRELIMINARY POINT TEMPS/POPS...
