Area Forecast Discussion National Weather Service New Orleans LA 339 PM CST Mon Jan 18 2021

SHORT TERM. Nothing exciting in the short term besides temperatures warming to the upper 60s to low 70s starting tomorrow. This warming pattern will continue to trend through the week as moisture makes its way back into the area by Thursday.

LONG TERM (Thursday through Sunday). Looking ahead, as mentioned previously high pressure over the SE portion of the US along with southernly flow will allow for temperatures to increase and moisture to return to the region. Can expect for rain to begin moving into our area as soon as Thursday. This warm and wet pattern is likely to continue through the weekend. Overnight lows will be in the upper 50s to low 60s for much of the week and winds are expected to remain light to moderate.

With dewpoints being warmer than the water temperatures by reaching 60 overnight Thursday, we could experience some sea fog. However, it is still too far out to be completely certain whether it will actually happen.

Minor adjustments were made to min temps in the long term to flow more with the neighbors. Otherwise, no major changes were made to the forecast. /TDB/

AVIATION. VFR conditions will prevail through the forecast period. /TDB/

MARINE. Winds have eased since this morning and have been fairly light all day. These winds will remain light ranging from 5-10 knots each day through much of the week. Wave heights will also behave with seas dropping to around 1 to 3 feet with the help of the lighter winds. Sea fog may be possible towards the end of the week but confidence is still low. /TDB/

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.
