193 FXUS64 KCRP 150932 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 332 AM CST Fri Nov 15 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Saturday) Issued at 224 AM CST Fri Nov 15 2024 Key Message: - Coastal flooding during high tide remains our greatest concern in the short term Light north to northeasterly winds this morning will shift back onshore this afternoon as the surface high moves eastward. Low- level moisture will increase through Saturday, resulting in an increase in cloud cover and warming temperatures. Only have a low chance of showers over the offshore waters on Saturday but moisture will remain below normal over land to warrant any mentionable PoPs. Highs today will range from the upper 70s to mid 80s, increasing a few degrees to the low to mid 80s on Saturday. Tonight`s lows will also be warmer than this morning, ranging from the mid 50s inland to the mid 60s along the coast. Coastal flooding will remain our greatest concern through Saturday during times of high tide, generally in the afternoon to evening hours. Astronomical high tide occurs today under a full moon and the return of onshore flow with increasing swell periods as we head into the weekend will aid in higher water levels. && .LONG TERM... (Saturday night through next Thursday) Issued at 224 AM CST Fri Nov 15 2024 Key Messages: - Hazardous Marine and Coastal conditions will persist through next week - Lows in the 50s early next week falling to the 40s by the end of the week. -There is a medium chance (50 to 60%) for wind gusts past 40 MPH Sunday night into Monday morning, and Gales in the offshore waters. It is beginning to look like a more fall weather pattern...Over the weekend the moisture increases to over 1.50"-2.00" PWAT values, which remain through Monday just prior to the cold front passing through the region. Rain chances with the initial moisture surge are low to medium chances on Sunday (25-50%), Sunday night around 20- 35%, then 50-85% on Monday with the front. Most of the rain is expected to be along the Coastal Bend and in the Victoria Crossroads, as the southerly flow looks to introduce dry air over the Rio Grande Plains and the Brush Country, keeping the probabilities low (<20%). Once the front is through, the cool high pressure, starting in the Pac NW begins to push the cool air south into Texas, across the Hill Country and into the Coastal Plains. The temperatures with this cool air gets progressively cooler. Monday the lows will range from the lower 50s to the mid 60s, Tuesday night (through the 50s across South Texas), Wednesday night and Thursday night through the 40s. The probabilities of getting below 40 on those nights are better than 55% for the Victoria Crossroads and some of the northern Brush Country. So upper 30s are not out of the question during the middle of next week. Winds...There are two times where there is concern. The first is Sunday night as the cold front approaches the pressure gradient tightens up, and the models are expecting wind gusts around 40 MPH in the central part of the Brush Country (Freer). While most of the wind gusts from the NBM are expected to be 35-40 MPH, there is a 50- 60% chance for wind gust past 40 mph. The question will be how frequent? If the models bring in a stronger gradient a wind advisory may be needed. The second time is post frontal once the cold air spills out on the Coastal Plains on Wednesday gusts 30-35 MPH look likely and gusts past 40 MPH are around 30% chance. The wind issue then become a more maritime issue with the warm waters and chilly overnight lows, which will allow for more mixing with a 25-30 knot wind at 925 mb and 850 mb. && .AVIATION... (06Z TAFS) Issued at 939 PM CST Thu Nov 14 2024 VFR conditions persist through this period. Mainly light winds and clear skies are expected. Toward the end of this period we will start increasing moisture into the area and just after the end of this period will likely see development of some low clouds. This will be noted in the next TAF cycle. && .MARINE... Issued at 224 AM CST Fri Nov 15 2024 Weak east-northeasterly winds today will shift onshore tonight through Saturday, strengthening to 10-15 knots. Onshore flow becomes moderate to strong and wave heights increase Sunday ahead of our next cold front early next week, leading to another period of Small Craft Advisory conditions, and possibly gales. Advisory conditions will likely be needed through at least the middle of next week as strong to very strong northerly winds and elevated seas will prevail behind the front, with the potential for gusts to reach gale force. There is a medium chance for showers and thunderstorms Saturday night into Sunday, and thunderstorms are expected Sunday night into Monday morning. && .PRELIMINARY POINT TEMPS/POPS...
