166 FXUS64 KLIX 112345 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 645 PM CDT Fri Jul 11 2025 ...New AVIATION... .SHORT TERM... (This evening through Saturday night) Issued at 250 PM CDT Fri Jul 11 2025 A few afternoon storms have developed across parts of the CWFA at the time of this discussion. As of now, the higher concentration of convection is across the southshore or along and south of the I10 corridor. Coverage is mostly widely scattered, less than days past as an upper level ridge continues to retrograde into the region. Shower and storm activity should come to an end around or shortly after sunset. Overnight the main concern will be the potential for fog over the southwest MS Counties. Saturday looks to be a skosh warmer than today as the ridge continues to build further over the region. The ridge will help limit but not fully stop convection from developing. The best potential will be west of the Lakes/I55 corridor closer to a decaying H5 shear axis over northwestern portions of the state. (Frye) && .LONG TERM... (Sunday through Thursday night) Issued at 250 PM CDT Fri Jul 11 2025 Going into the second half of the weekend rain chances are not zero, but they are not as high as climo POPs, again with the upper ridge sitting over our region. There may be a weak impulse at H5 that if timed with the daily sea/lake breeze could ignite a bit more convection than currently advertised, so that`s something to watch. Going into the start of the new workweek, temperatures are going to go from hot to potentially dangerous with heat index values approaching headline criteria if not Sunday most certainly Monday and beyond with some heat index values exceeding 110F on Tuesday. This would likely be an areawide heat advisory PLUS situation basically for all of next week. There will be chances of showers and thunderstorms during the afternoon hours. However, the rain chances will need to be watched mid to late week next week as an easterly wave begins to slide under the H5 ridge that by then will be sitting over the Nashville Basin. The finer details are a bit fuzzy with most models not really agreeing on placement and strength. However, the steering currents will weaken a good bit, which may be the first signal for a potential hydro event setting up, especially if the GFS and CMC are correct. Nothing set in stone, but something to monitor as we sweat out the next few days. (Frye) && .AVIATION... (00Z TAFS) Issued at 638 PM CDT Fri Jul 11 2025 Most of the convection over land has dissipated this evening, only leaving some very isolated showers across the area, mainly in the vicinity of MCB. Expect the residual showers to dissipate fully by the time the sun sets this evening. If those showers nearby MCB can saturate the ground enough at MCB, IFR conditions could be a concern right around daybreak, but current guidance is suggesting conditions will remain VFR. Otherwise, convective activity is expected to pick up again tomorrow afternoon, mainly across the western and northern portions of the area impacting BTR and MCB, therefore TEMPO groups have been mentioned there. However, for the rest of the sites, although confidence is not as high for convective coverage, the pattern remains very much summer-like, so mentioned PROB30 at the rest of the sites due to the expected scattered nature of the convection across the rest of the area tomorrow afternoon. && .MARINE... Issued at 250 PM CDT Fri Jul 11 2025 High pressure will set up over the local waters through much of the forecast period. This will keep winds light and variable. Overall favorable marine conditions expected. That said, there could still be diurnally driven convection, especially during the late night and morning hours. In and around convection expect locally higher winds and seas at least briefly. (Frye) && .PRELIMINARY POINT TEMPS/POPS...
