| Area Forecast Discussion National Weather Service New Orleans LA 104pm CDT Wednesday May 8 2024 Long Term (Friday through Tuesday) Issued at 330am CDT Wednesday May 8 2024 Any residual shower/storm activity lingering over from the short term period will quickly exit stage east and south. At the surface, the cold front will continue to drop southward as an upper level Canadian trough continues to amplify over the eastern U.S. With lower heigheights and thicknesses along with low level CAA, temperatures will be slightly cooler on Friday. That said, above average temperatures are anticipated to continue especially closer to the coast. Despite the weak cold air advection, strong insolation/sun angle will help keep things on the warm side. Going into the weekend, a more progressive pattern takes over. Temperatures start out around average on Saturday and Sunday with a more zonal flow over the region. However, all eyes begin to shift upstream later into Sunday. The next H5 shortwave, this one with Pacific roots, will migrate over the high plains. This will help the front that pushes through late in the short term period or early in the long term period lift back closer toward our region. With surface convergence and perhaps some help from isentropic upglide, POPs increase later into the weekend and especially to start the new workweek. One question is how far north the front will get and how progressive the H5 trough will be. The surface high takes some time to migrate eastward into the Mid Atlantic states this weekend and so return flow will be limited initially. That said, a very moisture rich environment isn't far and with the front lifting northward it wouldn't take long to moderate the low level moisture profile. Going deeper into the new workweek next week, it appears that a series of upper level impulses within the flow move over our region leading to perhaps periods of showers and thunderstorm activity. Models are still in a bit of a disagreement with the exact strength of upper level features and any surface trough/low development that takes place across the northern Gulf, but feeling a bit more confident with strong Quantitative Precipitation Forecast signals despite the slight disagreements amongst the ECM and GFS. Needless to say with the increase in cloudiness and rainfall, temperatures will be held down or more closer to climo norms. (Frye) Marine Issued at 330am CDT Wednesday May 8 2024 Winds will gradually increase today through Thursday with cautionary headlines needed up until a cold frontal boundary passes through the region early Friday. Behind the front, moderate winds and seas will continue with northerly flow developing. This northerly flow will begin to breakdown quickly going into the upcoming weekend as surface high pressure begins to settle across our local waters.
