219 FXUS64 KMOB 181148 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 648 AM CDT Tue Jun 18 2024 ...New AVIATION... .AVIATION... (12Z TAFS) Issued at 648 AM CDT Tue Jun 18 2024 Mostly VFR will persist throughout the day with a few scattered showers and storms possible along and south of interstate 10 this morning. Brief reductions in visby could be possible with any storms but impacts to aviation will be minimal. Winds will be out of the east-southeast around 10 to 15 knots with gusts up to 20 knots possible. BB/03 && .PREV DISCUSSION... /issued 421 AM CDT Tue Jun 18 2024/ ..New NEAR TERM, SHORT TERM, LONG TERM, MARINE... NEAR TERM... (Now through Wednesday) Issued at 421 AM CDT Tue Jun 18 2024 Well the forecast has certainly trended drier the next couple of days as the upper ridge over the western Atlantic noses into the area. The reason for the stronger than originally advertised ridge is the presence of Potential Tropical Storm one over the Bay of Campeche/southwestern Gulf. While this system will likely drift westward into Mexico over the next couple of days, the heat released from this storm is aiding in strengthening the ridge of high pressure. Kinda like a car exhaust on a car engine. As a result, the ridge promotes more subsidence and slightly drier conditions the next 48 hours. The only rain chances today and tomorrow will likely be confined to the immediate coastline where moisture will be rich enough and the influences of the ridge will not be as strong. Otherwise, most of the area is expected to be dry the next 48 hours. However, PTC one will have an impact on area beaches as waves will be on the general increase leading to a HIGH risk of rip currents and large breaking waves at the beaches leading to a high surf advisory. BB/03 SHORT and LONG TERM... (Wednesday night through Monday) Issued at 421 AM CDT Tue Jun 18 2024 An elongated upper ridge extending from the western Atlantic to the southern Great Plains will slowly sag southward through Friday night, and then retrograde westward over the weekend with upper troughing advancing eastward over the northern Great Plains and Great Lakes regions. Much of the precipitation will stay out over the Gulf through Friday, but we do expect isolated to low-end scattered showers and thunderstorms mainly in the afternoon in association with the sea-breeze boundary pushing inland with the best chances remaining across our coastal zones. Rain chances look to increase over the weekend (20-40%) and especially on Monday (60%) due to increasing weakness aloft as the upper ridge retrogrades westward. Daily highs will stay warm in the lower to middle 90s through Friday, pushing into the middle to upper 90s (about 3-7 degrees above normal) over the weekend into early next week. Overnight lows remain toasty with generally lower to middle 70s expected. A High Risk of rip currents will remain in effect through at least Friday. Surf heights will remain around 5 to 7 feet during this period. /22 For the tropics, there`s a couple areas of interest to watch over the next week. The first is in association with PTC1 in the southwestern Gulf of Mexico. This system will remain well to our southwest and the only impacts from it will continue to be increased surf heights through Thursday and rip currents through late week into the weekend. Late week into the weekend models continue to be divergent on their solutions for the southwest Atlantic system. The good news is it appears the system is further east than anticipated initially, which means the odds of it staying well east of the forecast area are increasing. MM/25 MARINE... Issued at 421 AM CDT Tue Jun 18 2024 A moderate to strong east-southeasterly flow will persist throughout the marine zones through Thursday in response to PTC one in the Bay of Campeche and a large area of high pressure over the southeast. Small craft conditions with near gale force gusts will persist through most of the week with seas also increasing to around 7 to 9 feet offshore with 2 to 3 feet in nearshore bays and waterways. Winds and seas are expected to slowly diminish by the weekend. BB/03 && .PRELIMINARY POINT TEMPS/POPS...
