| Area Forecast Discussion National Weather Service New Orleans LA 632am CDT Monday Oct 13 2025 .SHORT TERM... (Tonight through Tuesday night) Issued at 627am CDT Monday Oct 13 2025 Heading into the start of our work week we will warm a couple degrees thanks to a ridge building in from the west. This ridge will slowly progress eastward, becoming more centered over our area on Tuesday. This will bring yet another degree or two temperature increase for afternoon high temperatures on Tuesday. While we may warm up a touch, the dry air that filtered in over the weekend is here to stay for the next couple days which will help keep a more pleasant feel outdoors in the afternoons. Our upper level high pressure and this dry air lead to no rain chances in sight for the short term forecast period. Kept edits in for the early morning low temperatures as we saw much cooler temperatures Sunday morning than the NBM had. This brings Monday morning lows into the low to mid 50s for many. Additionally, similar to previous days blended in the NBM10 for afternoon dew points. Long Term (Wednesday night through Sunday night) Issued at 627am CDT Monday Oct 13 2025 Heading into the long term period, the upper level high will be pretty centered over the state on Wednesday. We will gradually start to see this high break up heading into late week as an upper level trough gradually pushes eastward from the west coast. The high breaking down allows rain chances to begin to creep back in heading into the weekend. Both Saturday and Sunday showing Probability of Precipitation up into the 25-35% range after all week seeing ~0%. In terms of temperatures, by Wednesday we will be back up to ~5-7 degrees above climate normals for this time of year. Looking at the CPC outlooks for temperature does not give any good news for the future of temperatures either. We will keep cooler mornings Wednesday and Thursday, but those low temperatures will also jump back into the upper 60s to lower 70s by late week as well. Marine Issued at 627am CDT Monday Oct 13 2025 Northerly offshore flow will persist today through early/mid-week thanks to high pressure over the eastern US and a developing low off the Carolina coast. This will keep conditions benign with light waves/seas and winds, as well as dry conditions. East to east- southeast flow does pick up some mid/late week, ranging 10 to 15 knots but will remain low impact and mainly dry into next weekend.
