| Area Forecast Discussion National Weather Service New Orleans LA 710pm CDT Thu September 24 2020 Extensive cloud cover over the area needed some forecast sky cover adjustments for the current trends. Otherwise, forecast was generally on track with only some minor adjustments made to the hourly temperatures and dewpoints. Forecast updates have been sent. 22/TD Beta's remnants currently are moving northeastward around the Mississippi/Alabama/Tennessee border. It is leaving us with a extensive clouds spanning from the upper Texas coast to just north of the Louisiana coast northward into Arkansas and central Mississippi. Guidance generally was eroding the cloud deck too quickly so had to adjust the sky cover a bit to slow it down. After what's left of Beta exits our area, the Atlantic finally is quiet in the first time in the past month or so. Still not out of the woods for this year (also, it's 2020) but I'll take any quiet weather we can get. Some of the tides are still a bit elevated, particularly in Lakes Pontchartrain and Maurepas, but winds shifting westerly/northwesterly should help get all that extra water drained out. Downgraded any coastal flood warnings to advisories for the tidal lakes and in Hancock Co just for one more high astronomical tide cycle and then water levels should get low enough that those can be dropped tomorrow afternoon. Dry air and fall like weather will be in the area before two cold fronts will be passing through the area. The first one is associated with a shortwave getting cutoff low around eastern Texas. This one has some potential for showers and thunderstorms so put in slight chance PoPs. The second cold front is forecast to reach the area late Tuesday and Wednesday and is associated with a much more vigorous digging upper level trough. This front looks to be dry for the most part with PW being around 0.5 inches. -BL AVIATION... Satellite indicates extensive MVFR (Marginal Visual Flight Rules) cloud deck at the internal sites for the next 24 hours. There may be some back and forth between VFR and MVFR (Marginal Visual Flight Rules) conditions for terminals near the coast. /TDB/ Marine Discussion Small craft advisory criteria hazards were canceled as the winds and seas diminished this morning. High pressure expected to build over the northern gulf as the remnants of Beta move northeast. Model guidance shows a cold front moving through the coastal waters this weekend as well as another reinforcing front by the middle of next week. Winds are expected to remain light through the weekend, and pick up to moderate levels as the second front moves offshore due to cold air advection./TDB/ NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...Coastal Flood Advisory until noon CDT Friday for LAZ040-049-050- 058-060>062-072.
