701 FXUS64 KLIX 081741 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 1241 PM CDT Sat Jun 8 2024 ...New AVIATION... .SHORT TERM... (Today through Sunday) Issued at 311 AM CDT Sat Jun 8 2024 High pressure dominates both upper and lower levels of the atmosphere through Sunday keeping the area dry and hot. As the high pressure shifts eastward, winds rotating around the high will become southerly this afternoon. The sky will remain clear until Sunday morning when a few clouds may develop with moisture beginning to return from the Gulf on the south winds. High temperatures will be in the low to mid 90s both days, but daytime humidities will be relatively low, on the order of 50%, so the Apparent Temperature stay in the low 100s. Therefore, no heat products are needed. However, because it is still relatively early in the season and most people are still acclimating to the summertime heat/humidity, everyone is urged to use caution if working outside. Taking breaks to cool down and drinking plenty of fluids will help to prevent heat related illness. && .LONG TERM... (Sunday night through Friday) Issued at 311 AM CDT Sat Jun 8 2024 An upper low over New England and a moderate ridge over the Four Corners will start the extended period. The Low will trail a weak front that will drop down to the vicinity of the coast Monday into Tuesday. The front, combined with Gulf moisture, pushes afternoon PoPs into the 50 range. However, the question of the exact location of the front, further north in our area or further south toward the coast will have a bearing on exactly where rain will occur. That said, for this time of year my thinking is that the front and focus for more rain will be on the central to northern side of our area. As the week progresses another upper disturbance will be moving into the lower Mississippi Valley from the northwest. There is quite a bit of uncertainty regarding how this system will eventually evolve and move, but it looks to interact with a plume of tropical moisture emanating from the Caribbean to result in more increased rain chances and possible surface low development. The resultant forecast calls for continued scattered showers and thunderstorms Friday into the weekend. But we will likely see changes in the forecast with at least a couple periods of more enhanced rain chances as the eventual evolution of the system becomes a bit clearer. && .AVIATION... (18Z TAFS) Issued at 1238 PM CDT Sat Jun 8 2024 VFR conditions will prevail through the day at all terminals. Light easterly winds becoming southerly thru afternoon and evening. Could see some patchy fog at MCB and BTR per guidance around sunrise but will clear quickly afterwards. Next TAF period could include VCTS line for HUM for pop up storms returning to forecast on Sunday afternoon. && .MARINE... Issued at 311 AM CDT Sat Jun 8 2024 Winds have made the transition around the high pressure, returning to southerly and remaining light. A frontal system will slowly progress southeast through early next week that should stall offshore Wednesday bringing northerly winds to the area once again. All of these winds will be 5-10 knots or less, but locally higher winds and seas will be possible with any storms that develop starting Sunday into next week. && .PRELIMINARY POINT TEMPS/POPS...
