| Area Forecast Discussion National Weather Service New Orleans LA 645pm CDT Wednesday Oct 5 2022 .SHORT TERM... (This evening through Thursday night) Issued at 259pm CDT Wednesday Oct 5 2022 Definitely a lot more sun today as the high clouds didn't materialize. This allowed afternoon temps to inch a few more degrees upward with most of the area in the lower to mid 80s. Locations that had the cooler temps were mainly right along the coast of MS where a weak seabreeze was able to keep temps in check just enough. For the next few days the forecast could be almost a carbon copy. We will remain dry and could even advect a little drier air into the area over the next 48 hours to hopefully lead to morning lows remaining similar to what we had this morning. Dry conditions, extremely dry soils, fairly clear skies, and light winds will allow for favorable radiational cooling conditions. If we can mix in even slightly drier air from the north and northeast we should be able to cool quite efficiently overnight. As for afternoon highs that may be a slightly different scenario. Mid level ridging currently over the TN/OH Valleys should quickly flatten out as it moves east towards the Atlantic coast tomorrow. As this occurs it looks like a deepening L/W trough will begin to take shape over the eastern CONUS however, it may not be until this weekend before we finally begin to feel some impacts from it. Between that L/W trough and a closed cut off low expected to develop over the Baja and much of northwestern Mexico there will be ridging in place. The ridge axis will stretch from around the southern Rockies to the SE into the western Gulf and then continue due east towards the Ridge sitting over the Bahamas (One very positive aspect of that ridge...it will keep all tropical mischief well south in the Caribbean and at least through much of next week). With the ridge axis just off to our west LL temps will continue to warm west of the area and slowly build east into the region. This will lead to highs tomorrow possibly a degree or two warmer and then on Friday highs could be back into the upper 80s. As we head into the weekend the large L/W trough should finally suppress the ridge enough and allow LL temps to drop a few degrees hopefully providing another very pleasant weekend. One rather negative aspect of the forecast though, we look dry and likely to remain dry through the forecast. /CAB/ Long Term (Friday through Tuesday night) Issued at 259pm CDT Wednesday Oct 5 2022 Zonal flow aloft will be the dominant pattern for the end of the week. Northerly to easterly surface winds will act to enhance dry and cool air advection into the area late this week into the weekend. A lack of deep layer moisture this weekend will contribute to a mostly dry long term forecast. Friday, high temperatures will warmer than normal ahead of a dry boundary that will move through on Saturday. Highs will be approaching 90 for most locations Friday. Otherwise, temperatures will be in the mid 80s all week and weekend, and conditions will be quite dry and comfortable. MSW Marine Issued at 259pm CDT Wednesday Oct 5 2022 Not much to really say for the coastal waters until the weekend. Weak broad high pressure will continue to dominate the region with winds likely having a greater influence from diurnal changes than anything else. Finally as we head into the weekend a more stout surface high pushing south through the Plains should tighten up the pressure gradient enough to get at least moderate northeast winds and can't rule out the possibility of headlines being needed at some point this weekend. /CAB/ NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...None.
