Area Forecast Discussion National Weather Service New Orleans LA 1129pm CDT Monday Jun 16 2025 Long Term (Wednesday through Sunday night) Issued at 336pm CDT Monday 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 heigheights 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 heigheights 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) Marine Issued at 336pm CDT Monday 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.
