308 FXUS64 KCRP 160731 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 231 AM CDT Sun Jun 16 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Tonight through Monday night) Issued at 147 AM CDT Sun Jun 16 2024 High temperatures will continue to range from the low 90s along the coast to near 105 across the Brush Country today and Monday. Today, moisture will still remain limited leading to only isolated locations reaching heat index values of 110. A slow influx of deep tropical moisture will begin this afternoon and into Monday. This will lead to increase heat index values and could result in Heat Advisories Monday afternoon. There is a low (10-20%) chance of showers and thunderstorms over the coastal waters today, increasing to low to moderate (20-70%) chances over the waters and along the coast tonight and Monday. && .LONG TERM... (Tuesday through next Saturday) Issued at 147 AM CDT Sun Jun 16 2024 Key Messages: - National Hurricane Center has given an area of disturbed weather in the southwestern Gulf of Mexico a medium, 60%, chance of tropical cyclone development. - Increasing moisture will lead to a high (up to 90% chance) of showers and thunderstorms by the middle of next week. - Increasing wave heights and long period swell will lead to a higher risk of rip currents and minor coastal flooding. Deep tropical moisture will stream into the area from an area of disturbed weather in the southern Gulf beginning early this week. PWATs will soar to around 2.9" by Wednesday. A tropical wave will combine with this moisture and lead to periods of heavy rain this week, with the heaviest and most widespread rainfall expected Wednesday and Thursday. The timing of the tropical wave could shift a bit, leading to some uncertainty in the rainfall timing and amounts. Current QPF forecasts have increased from previous forecasts, with rainfall totals of 3-5 inches across the Brush Country leading to a Marginal Risk of Excessive Rainfall Wednesday and Wednesday night. Higher rainfall totals of 5-8 inches across and east of the Coastal Plains, leading to a Slight Risk of Excessive Rainfall Wednesday and Wednesday night. Isolated to scattered flash flooding will be possible Wednesday through Thursday (though, once again, timing could waiver a bit depending on the progression of the tropical wave). Increase swell and higher wave heights will lead to an increased risk of rip currents and minor coastal flooding next week. Should a tropical system develop over the southwest Gulf of Mexico, chances will increase. We will continue to monitor this disturbance and its possible effects on South Texas. && .AVIATION... (06Z TAFS) Issued at 1134 PM CDT Sat Jun 15 2024 VFR conditions are currently in place across all terminals. Winds will remain around 10 knots through the night before strengthening through the afternoon hours Sunday. Similar to last night, there will be brief window closer to sunrise where we can see MVFR vis/cigs develop at ALI and COT. There is a low chance for some isolated showers at CRP Sunday morning but confidence is not high enough to include in the TAF at this time. Gusty southeasterly winds will weaken shortly after 00Z Monday. && .MARINE... Issued at 147 AM CDT Sun Jun 16 2024 Weak to moderate onshore flow will increase to moderate to strong Monday into Tuesday. Winds will become strong by the middle of the week with Small Craft Advisory conditions likely. Wave heights will increase to 8-12 feet across the offshore waters this week due to a tropical disturbance in the southwestern Gulf of Mexico. The National Hurricane Center has given this disturbance a medium, 60% chance of development in the next 7 days. Regardless of tropical development, deep moisture will move into the area resulting in a 50-90% chance of showers and thunderstorms by the middle of the week. && .PRELIMINARY POINT TEMPS/POPS...
