475 FXUS64 KCRP 131801 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 101 PM CDT Tue Aug 13 2024 ...New AVIATION... .SHORT TERM... (Tonight through Wednesday night) Issued at 155 AM CDT Tue Aug 13 2024 Key Messages: - Heat Advisory in effect for portions of South Texas through this evening. - Low to medium rain/thunderstorm chances east today and Wednesday. Low to medium (20-40%) rain and thunderstorm chances remain in the forecast today as a moist airmass combines with a passing mid level disturbance on the southwestern periphery of the high to spark some shower activity. Rain chances will start off higher over the coastal waters in the morning, before transitioning into the Coastal Plains by the afternoon hours along the seabreeze. The convective activity is progged to taper off during the overnight hours tonight, but another round is then expected on Wednesday, mainly along the seabreeze (PoPs 20-30%). Another couple of hot and humid days are in store for South Texas today and tomorrow with highs ranging from the upper 80s along the coast to near 105 out west. With the moist airmass in place, dangerous heat index values can be expected both afternoons, with values up to 114 degrees at some coastal and inland locations. A Heat Advisory is in effect from noon through 7 PM this evening for the Coastal Bend and Victoria Crossroads. Another Advisory is likely to be required on Wednesday as conditions will be very similar to today. If spending time outside, don`t forget to drink plenty of water, wear light-colored and loose clothing, and take frequent breaks from the heat. Also, look before you lock and keep your pets safe from the heat. && .LONG TERM... (Thursday through next Monday) Issued at 155 AM CDT Tue Aug 13 2024 Key Messages: - A moderate to extreme risk of heat-related impacts is expected daily through early next week. Hot and humid. I know we are all tired of hearing it, but it is August in South Texas so we know that`s what we are going to be saying for awhile. High pressure will be in control through much of the period leading to higher temperatures. A southeasterly flow will continue which will keep deeper moisture in the area (PWATs still expected to be around 1.8-2" through early next week). While unlikely, moisture could still be sufficient for a few showers or thunderstorms along the sea breeze in the afternoons. Heat is still our main concern through early next week. Most areas will be in a moderate to major risk of heat related impacts, with those across the northern Brush Country experiencing an extreme risk of heat related impacts. Heat index values up to 114 are likely each afternoon through early next week, with isolated locations reaching above 115. Heat Advisories will probably be needed each day, with a low potential for Excessive Heat Warnings. && .AVIATION... (18Z TAFS) Issued at 1258 PM CDT Tue Aug 13 2024 VFR conditions are expected throughout this TAF cycle with gusty winds this afternoon. Winds are expected to decrease around 02/03z across the eastern sites and 08/09z across the western sites before picking up once again late tomorrow morning into tomorrow afternoon. && .MARINE... Issued at 155 AM CDT Tue Aug 13 2024 There is a low to medium 20-40% chance for showers and thunderstorms through the day Wednesday. Otherwise, generally dry conditions will continue through early next week across most of the Middle Texas Coastal Waters. A weak to moderate south- southeasterly flow can be expected through early next week. && .PRELIMINARY POINT TEMPS/POPS...
