Area Forecast Discussion National Weather Service New Orleans LA 341 AM CST Sat Feb 29 2020

SHORT TERM. Dry cool conditions to continue through the weekend with a slow warming trend and some moisture making its way back to the area starting Sunday. This will also introduce the possibility of marine fog by Monday or Tuesday or both. There are a few indicators of this but as it goes with fog, we will need to be rather close in time to it forming before confidence will be high enough to introduce into the fcast. Models as expected are all over the place with this system and likely won't be agreeing on a common solution until at the earliest Sunday morning 12Z model runs but most likely on the 00Z Monday run which is Sunday evening. The presentation regarding orientation of mass and thermal fields looks better with the GFS but the timing is highly questionable. The EURO is not promoting this same idea, whereas both the presentation and timing looks questionable. Thinking is that the EURO is too slow. Basically something in between the two models would look better as far as timing while the presentation may be trying to elude to some prefrontal activity developing either Tuesday or Tuesday night while the front moves through Wednesday morning or afternoon. But we have a good bit of time to iron out the details.

AVIATION. VFR through this taf cycle.

MARINE.

Will drop all headlines with package issuance as winds have dropped off quickly since 06z. Pretty benign conditions today and most of Sunday as high pressure moves across the area. Could need some Exercise Caution headlines over the outer waters late Sunday as onshore flow returns. Main concern for marine interests will be late Tuesday into Wednesday as next system approaches. Quite a bit of disagreement between GFS and ECMWF solutions on timing for that system. At this point, current wind forecast is a compromise between the two on timing, so a shift in timing of any strong winds is possible, if not likely. Marine interests should keep updated on the forecast for mid-week. 35
