| #1228160 (Received by flhurricane at: 5:03 AM 26.Apr.2025) AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 344 AM CDT Sat Apr 26 2025 ...New SHORT TERM, LONG TERM, AVIATION, MARINE... .SHORT TERM... (Today through Sunday) Issued at 338 AM CDT Sat Apr 26 2025 Some patchy fog formation occurring this morning, but should remain isolated with only a few locations having dense fog. We could see a few more loctions with dense fog tonight depending on the cloud cover. Otherwise, there could be some sh/ts around today but most areas will be dry. The next several days sh/ts will be few and far between though. No issues expected with any activity, if able to develop, today. Sunday will show slightly better chances of rain than today mainly north but temps will begin to rise and a few 90s could start showing up. && .LONG TERM... (Sunday night through Friday) Issued at 338 AM CDT Sat Apr 26 2025 We will still remain under a general weakness with mainly diurnally driven sh/ts through the first part of the week. But by mid week, we will see strong capping take place with high pressure building over the area for the remainder of the work week. A cold front is advertised to move toward the area by next weekend which could provide some sh/ts for the weekend and we will need to get closer to that time frame to see how strong this activity will be. && .AVIATION... (12Z TAFS) Issued at 338 AM CDT Sat Apr 26 2025 MVFR to IFR cigs and vis for a few locations this morning will quickly move to VFR. The same issues for tonight is expected with several sites having IFR vis possibly around sunrise. && .MARINE... Issued at 338 AM CDT Sat Apr 26 2025 High pressure will be centered directly over or just to the east of the waters through this fcast which will result in light winds of around 10 knots and seas of 1 to 3 feet on average. Fog could be an issue this morning and again tonight on the Miss River but not expecting issues over warmer waters. && .PRELIMINARY POINT TEMPS/POPS...

| #1228134 (Received by flhurricane at: 1:15 AM 26.Apr.2025) AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 1203 AM CDT Sat Apr 26 2025 ...New AVIATION... .SHORT TERM... (This evening through Sunday night) Issued at 1231 PM CDT Fri Apr 25 2025 Once convection wanes this evening the remainder of the short term will be fairly quiet. Upper level high pressure will build over the area, effectively putting an end to rain chances through the weekend. The high pressure will also allow for mostly sunny to partly cloudy skies and the ample sunshine will make for warm afternoons. Afternoon highs will be in the mid to upper 80s, running about 5 degrees above normal in most locations, with peak afternoon heat index values near or just over 90 degrees. While these heat index values would be a welcome treat come August, this early in the season, the combination of the high sun angle and warmer than normal temperatures will lead to a slight increase in heat risk across the region - especially for those participating in the myriad outdoor festivals across the area, and even more so for any out of town visitors. Those with outdoor plans should take precautions to stay safe from the heat by staying hydrated, wearing lightweight and light-colored clothing, and using sunscreen. && .LONG TERM... (Monday through Thursday night) Issued at 1231 PM CDT Fri Apr 25 2025 High pressure continues to dominate the area through the first part of the work week, leading to continued warmer than normal temperatures and low rain chances. Wednesday will be a transition day of sorts as stubborn southern stream energy finally kicks out of the desert southwest toward the middle Mississippi Valley. As the upper trough moves eastward it will cause the upper ridge to flatten and shift eastward away from the local area. Sensible-weather-wise it still looks fairly quiet locally on Wednesday, though a couple stray showers and storms may develop during the afternoon, especially across northwestern areas. As the upper trough continues eastward, a surface low will move into the middle Mississippi valley on Thursday, forcing a cold front southeastward into northern Texas and Arkansas. While this front is unlikely to ever reach the local area, an influx of moisture ahead of the front will lead to increasing rain chances on Thursday in the form of diurnally forced scattered showers and thunderstorms. && .AVIATION... (06Z TAFS) Issued at 1155 PM CDT Fri Apr 25 2025 Convection has come to an end and all terminals are in VFR status at the moment. However, some terminals may see a few hours of MVFR and IFR and maybe even LIFR conditions as low cigs and possibly fog impact a few temrinals. Main contenders are MCB, BTR, HDC, and HUM but all with possibly the exception of NEW and GPT may see some impacts. Whatever fog or low clouds develop will quickly dissipate by 14z with VFR conditions and light winds tomorrow. /CAB/ && .MARINE... Issued at 1231 PM CDT Fri Apr 25 2025 Expect benign conditions to prevail through at least the next 5 days as high pressure remains in control of the northern Gulf. While there may be a few periods of winds in the 10-15 knot range, winds will generally be less than 10 knots with seas 1-3 ft. && .PRELIMINARY POINT TEMPS/POPS...
