590 FXUS64 KLIX 061741 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 1241 PM CDT Sat Jul 6 2024 ...New AVIATION... .SHORT TERM... (Today through Sunday) Issued at 320 AM CDT Sat Jul 6 2024 A gentle split flow is occurring over the area this morning from the interaction between the upper outflow from Beryl and an upper trough to the north. This along with very high PW values will help storms get going quite easily around sunrise again today and possibly again on Sunday. There is not a lot of storm motion today or Sunday so these storms will develop and decay mostly over the same area they get started over. Water temps are close to convective temps so there could be some morning sh/ts that develop today before sunrise but most activity will be after sunrise today and Sunday. These will be very efficient heavy rainfall producers and since they will not be moving much(more propagation than movement), they will have the potential to drop several inches in a short time which could cause ponding and flooding in some locations. The numerous sh/ts that will be around will also help keep temps somewhat lower with the cloud cover. This is why we will not be issuing a heat advisory for today. But there will be a few locations that could get heat index readings up to around 108F during the hottest part of the day, especially if there is no cloud cover for those locations. The environmental conditions are also very conducive for waterspout/landspout activity as well. Although these are not normally strong, they can still cause issues if caught in them. && .LONG TERM... (Sunday night through Friday) Issued at 320 AM CDT Sat Jul 6 2024 Beryl is still moving toward the Texas coast and is fcast to move inland Monday. The system will then begin to unravel meaning deep moisture profiles will remain across the area for the next several days. Models differ with picking this system up in the westerlies and kicking it to the NE. But regarless of which is right about it, it leaves our area with the same fcast and that is hot, moist and rainy. As the system moves north, it will leave a wake trough somwhere over Louisiana by mid week. This could be as far as western Miss, but we will need to see if that will occur. But either which way, it spells the same for the area through much of this upcoming week. && .AVIATION... (18Z TAFS) Issued at 1241 PM CDT Sat Jul 6 2024 MVFR ceilings currently in place from expanding CU field should continue to lift to VFR later this afternoon. Although gradient winds will be light and variable today, outflow boundaries from storms later today brings the potential for abrupt changes in wind direction. Scattered afternoon thunderstorms will be possibly this afternoon. Any storms that impact terminals will temporarily drop visibilities and ceilings into IFR to VLIFR category. Gusty winds upwards of 30+kts will be possible as well. Quiet and uneventful conditions after storms dissipate this evening. MEFFER && .MARINE... Issued at 320 AM CDT Sat Jul 6 2024 Somewhat higher swell from the south will continue to move through today. These look to be around 3ft and will be additive to the wind waves across the gulf and since the winds will be quite weak, this should be the highest seas out there. This change a bit as Beryl gets slightly closer to the most western portion of our waters bringing winds up to around 15-20kt and seas to around 4 to 5ft late Sunday into Monday. These conditions will stay west of the Miss River and begin to settle by Tuesday bringing the area back to a normal southerly wind flow around 10kt for the remainder of the week. && .PRELIMINARY POINT TEMPS/POPS...
