192 FXUS64 KLIX 232326 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 626 PM CDT Sat Aug 23 2025 ...New AVIATION... .SHORT TERM... (This evening through Sunday night) Issued at 135 PM CDT Sat Aug 23 2025 Tonight through Monday morning the frontal system will slide southward into the Gulf. Some scattered coastal showers and storms are possible during the afternoon hours right along the LA coast Sunday afternoon as it progresses south. These storms would have the potential for frequent lightning and gusty sub- severe winds (40-50mph) primarily. High temperatures will be in the mid 90s with dewpoints in the low 70s thanks to the drier conditions. As a result, heat index values will be in the upper 90s and early 100s. This will be a welcome break from the typical pattern and a nice relief in the heat! MSW && .LONG TERM... (Monday through Friday night) Issued at 135 PM CDT Sat Aug 23 2025 Monday through Wednesday a weak cool front will progress through the area. Some isolated to scattered showers and storms will be possible as this system slides southward into the Gulf. These storms will have the risk of gusty subsevere winds (30-50mph) and frequent lightning. Additionally, PWs will be around 1.8 to 2 inches, especially on Tuesday afternoon. So, rainfall could be fairly efficient, which could lead to ponding of low lying roadways. By Tuesday, temperatures will be feeling quite nice with highs in the upper 80s and low 90s. Lows will be in the upper 60s and low 70s. A ridge will build over the area Wednesday through the end of the workweek, which will bring drier conditions through the area. Little to no rainfall is expected at least Wednesday through Friday. Temperatures will be quite pleasant with highs in the upper 80s and low 90s with lows in the upper 60s and low 70s for the area.
