285 FXUS64 KLIX 120842 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 342 AM CDT Mon Aug 12 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Tuesday) Issued at 339 AM CDT Mon Aug 12 2024 High pressure moves east to be positioned more directly over the top of us. This adds a degree or two to our high temps and, more significantly, allows some Gulf moisture into the area. PW end up around 2.0 today and increase to 2.1ish tomorrow. Because the high is directly over us, winds are even lighter than the past couple days. Apparent Temperatures push up against the limit for a heat advisory, but aren`t quite there...yet. The high pressure will continue to force lower rain chances, but there are enough temperature differentials to develop some sea/lake breeze boundaries that may generate enough lift to kick off some convection. Nothing severe is expected, but there could be lightning and gusty winds associated with any pop-up storm that does happen to form. /Schlotz/ && .LONG TERM... (Tuesday night through Sunday) Issued at 339 AM CDT Mon Aug 12 2024 Wednesday through the end of the period sees continued high pressure dominance in our area, but a slight change to the synoptic pattern sees the possibility of a trough digging in just to our east. True impact of this pattern is not high, but is enough to increase rain chances slightly due to higher moisture availability as well as increased Apparent Temperature to trigger the need for Heat Advisory headlines. Any rain that occurs could be accompanied by lightning and gusty winds. /Schlotz/ && .AVIATION... (06Z TAFS) Issued at 1137 PM CDT Sun Aug 11 2024 Overall no real issues. All terminals currently in VFR and likely to remain that way for much if not all of the forecast. The only slight concern would be a rogue storm or two that develops in the afternoon along the lake breeze and/or sea breeze. /CAB/ && .MARINE... Issued at 339 AM CDT Mon Aug 12 2024 The dominant high pressure remains in place continuing the light winds and seas. Isolated to scattered showers will be possible daily primarily in the early morning, which could have lighting and gusty 30-40mph winds. && .PRELIMINARY POINT TEMPS/POPS...
