Area Forecast Discussion National Weather Service New Orleans LA 332 AM CST Sun Jan 17 2021

SHORT TERM. Some light freezing temps during the next few nights mainly for the most northern portion of the area. A slow warming trend will begin Tuesday.

LONG TERM (Wednesday through Saturday). Zonal upper level flow pattern and weak ridging will set up over the area Wednesday through Friday morning. Southerly surface winds these days will help to bring warm and moist air into the region. Weak upper level divergence will help to introduce some instability and lifting into the atmosphere, as well. As a result, temperatures are expected to be closer to normal later in the week with drier weather conditions.

Friday into Saturday, a weak shortwave upper level trough is expected to move through the Western US and then get wrapped up in an upper level zonal flow pattern by the time it reaches our area. As the remnants of this shortwave influence the zonal flow slightly, it will help enhance the potential for some rain in our area Friday night into Saturday morning, especially with the help of the warm and moist air that would already be in place over the area. This rainfall would likely be light or moderate and lightning potential would be low, based on the models currently. The potnetial for rain is highly dependent upon how these flow patterns develop over the next week.

Saturday evening and beyond, weak upper level ridging and zonal flow sets up again over our area with some drier conditions and more normal temperatures expected. MSW

AVIATION.

VFR conditions through this taf cycle.

MARINE.

Winds have eased quite a bit over the past 12 hours. The wind field will remain light with winds of less than 10 knots as high pressure continues to settle directly over the waters. Seas have subsided to around 2 to 3 feet in response to the lighter winds. Another front will push through on Sunday, and this will allow winds to increase to 10 to 15 knots for Sunday night and Monday. Return flow will begin to develop Monday night into Tuesday but should remain around 10kt then rise toward the end of the upcoming 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. 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.
