Area Forecast Discussion National Weather Service New Orleans LA 322 PM CST Mon Feb 24 2020

DISCUSSION. A low pressure system will be moving through our area today and Tuesday. Rain chances are higher tonight into the morning hours tomorrow. Mostly showers are expected with this system with amounts up to 0.5 inches of rainfall. It will be possible to get a thunderstorm or two with these storms, if daytime heating or moisture abundance from the Gulf enhance instability. Overall, some rainfall and a few thunderstorms are possible with this system, but nothing severe is expected.

A secondary shortwave frontal system is expected to move through Wednesday morning. With the passage of the frontal systems by mid- week, low temperatures are expected to be cooler Thursday and Friday mornings. Some locations will expect temperatures below or approaching freezing these mornings due to strong cold air advection into the area. High pressur will build in over the area after Wednesday. Upper level convergence will help to promote a stable atmosphere and sinking air into the environment. As a result of the more stable air, rain chances will very low Wednesday through Sunday. MSW

AVIATION. VFR conditions should last until the cold front to the northwest of the area terminals will be moving through late tonight into early tomorrow. Rain associated with this is already approaching BTR and should be basically SHRA or VCSH. Due to the front, there may be isolated thunder but confidence and impact is still too low to put any mention in the forecast. Once the cold front passes MVFR to IFR ceilings with some fog is possible. -BL

MARINE. Winds will be calm (<15 knots) and southerly through Tuesday afternoon. Tuesday night through Wednesday morning winds will be northerly and calm (<15 knots). Wednesday through Thursday afternoon, winds will be northerly and strong (15-25 knots). Thursday through Sunday, winds will be calm (<15 knots) and northerly to northwesterly. Wave heights will correspond to the winds. MSW

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
