Area Forecast Discussion National Weather Service New Orleans LA 427 AM CDT Sun Sep 27 2020

SHORT TERM. Some dense fog around this morning will prompt an adivsory through 9am today. More fog tonight but will have to see what cloud cover would like to do first before issuing for Monday morning. Warmest days will be today and Monday with highs in the mid 80s for the most part. After Monday, temps will struggle to stay in the low to mid 70s each day through the rest of the week. The cold front that will be responsible is currently located from Wisconsin to the TX/OK panhandles and will begin to move aggressively SE today through tonight. Some slowing of this front looks to occur as it moves through our area but it does not stall, just slows very little as stronger forcing falls in behind. There is a strong chance of a line of sh/ts along the front as it moves through Monday. Compressional heating ahead of the front will provide the conditions that some of these thunderstorms could take advantage of during the day Monday. The strongest thunderstorms look to develop over northshore areas but most areas should see rain. This front will be noticed quite well. New Orleans will be firmly seated in the mid 80s by 4pm Monday and 3 hours later should be falling into the upper 60s while on its way to temps in the 50s. All locations will do this with the passage of the cold front.

LONG TERM (Wednesday through Saturday) .

Expect dry coonditions and much cooler temperatures for the entire period. Lows are expected to drop into the 50s to lower 60s with highs mainly in the 70s and NO RAIN.

AVIATION. Cigs and vis restrictions should keep most sites in or around MVFR or IFR through sunrise but will become VFR shortly after. Another round of low cigs and FG again tonight.

MARINE. South to SE flow will remain today through Monday with speeds on the order of 10-15kt expected. Winds will shift with the passage of a cold front Monday night to northerly and rapidly rise to 20-25kt. This will prompt advisories for winds and seas Tue through early Wed. Winds and seas should rapily subside Wed into Thu and remain through the end of the week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
