| Area Forecast Discussion ...UPDATED National Weather Service New Orleans LA 520am CDT Sat Oct 10 2026 .SHORT TERM... (Now through Tuesday) Issued at 1027pm CDT Fri Oct 9 2026 Hurricane Isaias will move quickly north through Alabama the remainder of the night while weakening. A few rain showers can't be ruled out through mid-morning Saturday, but rainfall totals should be light. Winds will subside to 10 to 20 mph by sunrise, and then go calm overnight as high pressure moves into the area. High pressure will become centered over the area for Monday and Tuesday, with mostly dry weather expected beyond this morning. Clouds will decrease during the day Saturday, with highs getting into the lower 80s. With full sunshine Monday and Tuesday, much above normal high temperatures will return with most areas seeing highs from the mid 80s to perhaps the lower 90s in a few areas. Dry air will be in place, and with light winds expected during nighttime hours, lows the next few nigheights could fall into the 50s across the northern half of the area. Lake Pontchartrain's 80 degree water could hold the New Orleans area in the 60s or closer to 70. Coastal Flood Advisory is replacing the Storm Surge Warning through the current high tide cycle as some minor inundation could still occur. Long Term (Tuesday night through Friday) Issued at 1027pm CDT Fri Oct 9 2026 High pressure at the surface and aloft will remain pretty close to the local area through at least Thursday and probably Friday. A strong storm system moving through the Great Lakes late in the workweek could send a cold front southward toward the area by Friday. Even at that point, conditions don't look favorable for precipitation. Much above normal high temperatures will continue through the workweek, with highs in the lower 90s possible across much of the area through at least Thursday. If those temperatures are achieved, there may be some high temperature records broken or tied. If the cold from moves through the area next weekend, highs will fall off several degrees. Overnight lows should mainly be in the 60s. Marine Issued at 1027pm CDT Fri Oct 9 2026 Marine conditions will improve as Isaias continues to move northward away from the coast while it weakens. Tropical Storm and Hurricane Warnings were dropped, and replaced by Small Craft Advisories that will run through mid to late morning. It may take into the afternoon for seas to lower to a comfortable level for operations, but from Sunday onward, winds should remain below 15 knots across the waters until perhaps Thursday night or Friday of next week. This should keep seas in the 1 to 3 foot range, or less.
