AVIATION. Skies are mostly clr, and winds are slowly decreasing as high pres settles over the region. Generally quiet conditions anticipated through the period, with few changes from previous TAF thinking. Only adjustment was to insert TEMPO group at AEX as patchy fog could form near daybreak as temp-dewpoint spread continues to narrow and winds lighten acrs cntl LA.

Therefore looking at mostly clr skies ovrnght as winds relax twrds sunrise with the mrng low ranging from the mid 40s in cntrl La to near 50 along the I-10 corridor.

PREV DISCUSSION . /issued 646 PM CDT Tue Mar 31 2020/

DISCUSSION . 01/00Z TAF Issuance.

AVIATION . Swath of SCT/BKN stratocu based around 3500 FT continues to spread south acrs the area. Dry air filtering into the region will gradually dissipate the clouds over the next few hours, with SKC expected to prevail through much of the period. Gusty northerly winds will diminish, but should remain generally 5-10 KT overnight while shifting northeast as sfc high pres slides into the region. The high will allow winds to continue to lighten during the day Wednesday, bcmg VRBL or SE after 01/18Z as the center of the ridge passes east of the area.

PREV DISCUSSION . /issued 307 PM CDT Tue Mar 31 2020/

SYNOPSIS . Nice weather is expected for the next couple of days as a high pressure system brings a dry continental air mass to the region. This will allow for cool nights, mild days, and no rain. Flow off the Gulf will resume by the end of the week with a return to warm and humid conditions, along with chances for rain.

Rua

DISCUSSION . A cold front has swept through the forecast area with a drier continental air mass now settling in. This air mass will persist for the next few days bringing with it cooler more seasonable conditions, especially at night, along with mild days. Rain chances will be near zero for through the early part of Thursday.

The high pressure system that will bring the more seasonable conditions will move east to the Mid-Atlantic region by Thursday. Therefore, southerly winds will return allowing the Gulf to open up and bring back warm and humid conditions.

There are still some fluctuations in the Guidance over the weekend, but at this time Saturday looks like the day that will have the better rain chances, with Sunday possibly being a bit drier.

An unsettled pattern with very warm and humid conditions look to be in store for early next week.

Rua

MARINE . Elevated northerly winds will continue over the coastal waters tonight into early Wednesday as a cool high pressure system builds into the area. Wind speeds will exceed 20 knots at times for the coastal waters east of Intracoastal City so a small craft advisory will be in effect for that area. Winds will gradually decrease during the day on Wednesday as the surface ridge settles over the coastal waters. The high pressure will then move off to the east on Thursday with onshore flow returning that will then persist into the weekend.

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.
