544 FXUS64 KLIX 170429 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 1129 PM CDT Mon Jun 16 2025 ...New AVIATION... .SHORT TERM... (This evening through Tuesday night) Issued at 336 PM CDT Mon Jun 16 2025 An H5 trough remains over the region with mostly southwesterly upper flow across the region as a ridge sits over the Florida Peninsula. Most of the region outside of the local waters is currently seeing a bit of a break in terms of convection, however, looking upstream there is a cluster of showers and storms over south central Louisiana that is moving generally toward our region. Most of the area have been worked over from an instability standpoint, but through the afternoon if some recovery west of I-55 takes place, there could be another round of convection. With the coverage of convection today, temperatures have been a challenge. We had to lower max temps this afternoon based on cloud and precip trends. Going into tonight, most of the convection dissipates outside of maybe offshore later tonight and early Tuesday. Where it rains inland may see some patchy morning fog around sunrise or so, but this will mix out pretty soon after sunrise. On Tuesday, the overall pattern remains the same with active southwesterly flow over our region and additional mainly diurnally driven convection fires during the daytime. DCAPES during the afternoon are somewhat middle of the road or marginally favorable for a strong wind gust or two in the strongest activity, but the main weather impact outside of convection will be the heat...although with POPs running a bit higher and an early convective initiation time on Tuesday, temperatures may be held own a bit, similar to today. (Frye) && .LONG TERM... (Wednesday through Sunday night) Issued at 336 PM CDT Mon Jun 16 2025 Going into the long term not much overall changes. Expect the warm season pattern to continue with generally a slightly higher coverage of showers and storms out there each afternoon as the aforementioned trough continues to reside over our region. This will be a bit of a problem for high temps each day, but went a bit on the lower side initially with the higher POPs early in the period. Going later into the long term an H5 ridge begins to build west from the western Atlantic. This will help heights increase and although it doesn`t eliminate all rain chances, it will suppress the overall overage. That said, with some subsidence and drier air aloft, we`ll need to watch the dcape values and wind potential with any wider or more robust updraft during the afternoon. Otherwise, with the lower coverage and higher thicknesses and heights toward the end of the long term period, expect temperatures to climb well into the lower to middle 90s for afternoon highs. As for heat index values, they too climb and climb to a level of potentially needing a heat advisory this weekend. (Frye) && .AVIATION... (06Z TAFS) Issued at 1121 PM CDT Mon Jun 16 2025 VFR conditions currently across the area and expected to maintain through the night. Exception is at MCB where light patchy fog will have negligible impact of dropping VIS to 5SM, but CIG briefly drops to IFR heights around 12Z. Convection develops again tomorrow late morning, handled with TEMPOs and PROBs. /Schlotz/ && .MARINE... Issued at 336 PM CDT Mon Jun 16 2025 Overall, benign marine conditions expected through the cycle. Winds should generally be moderate at max with some gusts up to 15 knots or so toward the end of the week as surface high pressure interacts with the leeside trough across the high plains. Otherwise, diurnally driven convection typical for this time of year can be expected with locally higher winds and seas in the heaviest convection. (Frye) && .PRELIMINARY POINT TEMPS/POPS...
