Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion Bay: GMZ400
933 AM CST Wed Feb 24 2021

A weak surface front will stall north of the coastal waters tonight. Therefore, a mainly light onshore flow will continue through the end of the week. Some patchy sea fog may form over the near shore waters as the warm southerly flow persists.

Current forecast is generally on target, with region firmly within a warm air advection regime ahead of a slowly advancing frontal boundary. Despite the abundant cloud cover, temperatures should have no trouble climbing into the lower 70s, though did shave a bit off of the previous forecast. Also cannot rule out the possibility of isolated light showers, though better rain chances will hold off until tonight as the front sags into the area.

AVIATION... Currently all sites are VFR xpc ARA which has a vsby running around 2 sm in BR... ir stlt indcg broad cloud field advecting into coastal Texas and southern Louisiana coastal waters around the back side of the surface high. Clouds xpcd to rmn w/ vsby changing thru sunrise at ARA.

SYNOPSIS... A rather warm pattern will be place over the forecast area for the remainder of the week into the weekend. A weak frontal system will stall over the forecast area on Thursday and upper level impulses will provide a chance for off and on showers during this period.

Mainly clear skies and light winds are found across the forecast area this early morning with seasonal temperatures. Some patchy radiational fog is forming, mainly along and south of the I-10 corridor. This fog looks rather shallow, and should lift quickly with daytime heating.

A surface high is centered around Florida with a surface cold front moving southeast into the Southern Plains. This will allow for southerly flow across the forecast area allowing for warm temperatures and an increase in moisture. The increase in moisture will bring about more cloud cover today, with possibly a few mainly streamer type showers by afternoon.

The cold front will move into the forecast area later tonight, then stall across the forecast area as flow aloft becomes more zonal. A series of weak short waves moving over the front will help produce some shower activity, with rainfall amounts on the light side. South of the front, with warm and moist south winds moving over the cooler near shore waters, some patchy sea fog will be possible, however this looks to be mainly near the coast, as lift and winds seem to favor more low cloudiness further inland.

The surface front will dissipate by Friday with surface high east of Florida building across the northern Gulf of Mexico and providing a stronger southerly flow. Meantime, an upper level ridge will be building into the forecast area from the southern Gulf with upper level flow becoming more southwest.

This will result in rather warm conditions for the weekend with small chances for showers, along with patchy fog.

An upper level disturbance will move out from the Rockies early next week, cutting into the upper level ridge, and pushing the next significant cold front into the forecast area. The front will help increase rain chances, along with cooling down temperatures. Main push of cold Canadian air behind this front looks to move off to well northeast of the forecast area, so only a modest cool down expect behind this front.

Marine Discussion
A weak surface front will stall north of the coastal waters on Thursday keeping light onshore flow in place. The southerly winds will continue into the weekend as a surface high ridges from east of Florida across the northern Gulf. The warm and moist southerly flow may help produce periods of patchy sea fog over the near shore waters.
