Area Forecast Discussion National Weather Service New Orleans LA 1212 PM CST Tue Dec 10 2019

UPDATE.

Updated for 18z aviation discussion.

AVIATION.

MVFR to IFR conditions, mainly due to low CIGS and occasional lower visibility in SHRA are expected to continue through the afternoon with mainly MVFR expected tonight before improvement to VFR expected mid to late morning on Wednesday. Northerly winds are expected to remain gusty at most airports in the wake of the cold frontal passage through the afternoon and most airports near the coast and tidal lakes through tonight and Wednesday morning. 22/TD

PREV DISCUSSION. /issued 944 AM CST Tue Dec 10 2019/

UPDATE . Visibilities have improved across much of the area around Lake Pontchartrain in the past couple of hours, and this warranted allowing the dense fog advisory to expire in these areas. However, dense fog continues along the Mississippi coast and coastal portions of St. Bernard and Plaquemines. This fog also persists over the adjacent coastal waters. The fog should linger through 17 or 18z before beginning to lift with the approach of a cold front. This cold front is quickly tracking to the southeast, and is now extending from Pierre Part and Donaldsonville to Mandeville and Picayune. The front will continue to march southeast over the next few hours, and should be clear of the Louisiana coast by mid- afternoon. Temperatures have been adjusted slightly to account for frontal timing, but no significant changes from the previous forecast occurred with this update. Post- frontal rain showers will spread across the entire forecast area by late afternoon, and have high rain chances persisting into the night. High end small craft advisory conditions are still expected over the coastal waters tonight.

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.
