Area Forecast Discussion National Weather Service Corpus Christi TX 622 AM CDT Wed Aug 7 2024 ...New AVIATION... .SHORT TERM... (Today through Thursday) Issued at 214 AM CDT Wed Aug 7 2024 Key Messages: - Moderate to major risk of heat-related impacts today and Thursday. Now that I'm on short term, vs the long term of the last few nights, I can still say that the overall pattern hasn't changed much with the 500 mb ridge parked over the Intermountain West and monsoonal moisture moving into the Desert Southwest. Satellite is showing a plume of 1.75" PWAT air over the Gulf and the Coastal Bend. However, as has been the case over the last few days, with the ridge over the region, the chances of showers and thunderstorms are low (10-20%), and mainly in the afternoon with the sea breeze pushing inland today and Thursday. That just leaves the heat. High temperatures are slowly rising Today and Thursday with Thursday's high expected to be a few degrees higher than today. Most of the heat is expected to be out in the western Brush Country and the Rio Grande Plains where temperatures will approach 110°F, but of course, it'll be a dry heat with the Minimum RH around 25% both days. However, we are expected to have some areas achieve 110° heat index values out there, and that is where the major heat impacts are expected. Temperatures to the east will be a little lower, with the 100° isotherm roughly running along the Coastal Plains, and then dropping to around 90° at the Gulf shore. Of course the humidity will be higher, but on a whole the heat index may briefly reach 110°, but most locations remaining below that for today. Thursday, the humidity rises a bit, as does the temperatures, so there may be more areas along the Coastal Bend and the Victoria Crossroads where 110° heat indices are maintained for a few hours, just like out in the Brush Country. && .LONG TERM... (Thursday night through next Tuesday) Issued at 214 AM CDT Wed Aug 7 2024 Key Messages: - Moderate to major risk of heat-related impacts through early next week - Low (10%) chance of tropical development over the next 7 days Very little change with this long term forecast update. Mid to upper level ridging will remain in place aloft for much of the period. This will help keep us hot and dry for the next several days. High temps look to settle into the low 90s along the coast to around 105 out west daily. As we head into the weekend, a plume of slightly higher moisture will spread across the region. This will promote heat indices in the 110-114 range, generally along the coast and across the Brush Country. These warm temps and high heat indices will result in a moderate to major heat risk through early next week. As we head through the weekend, the upper level ridge will shift to the west, allowing for the aforementioned plume of moisture to spread inland. Have kept PoPs generally less than 20% but this increased moisture will open the door for some daily activity along the sea breeze. Overall, not too confident in coverage due to the lack of support aloft. Now for a quick look at the tropics. The National Hurricane Center continues to monitor a tropical wave moving across the Caribbean. Conditions are favorable for some development as this wave moves west over the next several days. There is a 10% chance of development over the next 7 days. && .AVIATION... (12Z TAFS) Issued at 612 AM CDT Wed Aug 7 2024 Looks like persistence will continue to be the best forecast for the TAF sites again. With the weak to moderate southerly flow (southwest to southeast) through the 24 hours, and the clear skies, CRP/LRD/COT will continue with VFR CIGs and VSBYs. ALI and VCT will again be the exception as moisture in the VCNTY of the TAF sites will produce temporary MVFR restrictions this morning through about 13z and at the end of the time period (10z-12z/Thu). && .MARINE... Issued at 214 AM CDT Wed Aug 7 2024 A weak to moderate south-southeasterly flow can be expected through early next week. Generally dry conditions are in store through the weekend. Moisture begins to increase early next weekend, leading a 10-20% chance of showers and storms. && .PRELIMINARY POINT TEMPS/POPS...
