Area Forecast Discussion National Weather Service New Orleans LA 1120 AM CST Thu Jan 23 2020

AVIATION. A band of light to moderate rain continues to push east this morning. Low ceilings ranging from 500 to 1500 feet and visibilities of 3 to 5 miles are accompanying this band of rain as it moves through. The rain band should finally clear KGPT by 00z. Farther to west, some dry air intrusion after the rain ends around 20-22z will allow ceilings to improve into MVFR range of 1500 to 3000 feet for the evening hours. However, an inversion is expected to develop tonight that will trap lingering low level moisture in place and promote the development of low ceilings late this evening through the overnight hours. Expect to see ceilings fall back into the 500 to 1500 foot range resulting in a mix of IFR and MVFR conditions. All terminals should drop into fuel alternate levels during the overnight hours. The cloud cover should quickly clear out tomorrow morning as drier air mixes down into the boundary layer with VFR conditions prevailing at all terminals shortly after sunrise. PG

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.
