Area Forecast Discussion National Weather Service New Orleans LA 415 PM CST Tue Mar 2 2021

SHORT TERM (Tonight through Friday).

The shortwave trough will continue to move east across the lower Mississippi valley tonight with the associated surface low moving east-northeast across the north central to northeast Gulf coast. The fairly widespread rain will end over eastern/offshore areas this evening. Drier and continued cool conditions will prevail with the sun returning during late morning to midday hours on Wednesday as high pressure builds in behind the front and low pressure area. The surface high will continue to build in on Thursday with a modifying airmass allowing high temperatures to push back up near normal after a cooler than normal period through Wednesday night. The next potent shortwave trough will move southeast through the central Gulf coast region late Friday, Friday night and early Saturday morning. The models depict generally light to moderate rainfall amounts with this system mainly late Friday and Friday night and very few if any thunderstorms.

LONG TERM (Saturday through Tuesday).

Surface high pressure will be in control with dry and mild weather expected over the weekend. As the surface high shifts east, the next system that may impact our region will be a shortwave trough moving through the western states early in the week. The mentionable rain chances at this point look beyond this forecast period. Temperatures should be near to slightly above normal and rather pleasant for early March.

AVIATION.

IFR to MVFR conditions should become mostly IFR later tonight into early Wednesday morning. Conditions will be improving to VFR with drier air and clouds clearing out from west to east during late morning and early afternoon on Wednesday. North winds will continue to gust 20 to 25 knots at times at the more coastal airports this evening with the strongest sustained winds at KNEW.

MARINE.

Strong north winds near or over 20 knots with higher gusts will continue into tonight. The Small Craft Advisories will remain the same as from the mid morning update. Winds and waves will subside on Wednesday through Thursday as high pressure builds into the region. Yet another weak low pressure system will move across the north Gulf late Friday and Friday night brining another period of moderate to stronger winds and increased wave heights late Friday night through the weekend.
