Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion Bay: GMZ400
311 PM CDT Sat Apr 10 2021

A cold front will continue to push through the coastal waters the rest of this afternoon and evening, bringing an offshore flow which will linger through Sunday. High pressure building past the region will allow an onshore flow to return for Sunday night and Monday before another frontal boundary moves into the northern Gulf and stalls, allowing for a more easterly flow to develop for the remainder of the forecast period.

Short Term - Tonight Through Sunday Night
CDFNT has recently pushed through KLFT per SFC observations, and is expected to continue progressing off to the SE the rest of this afternoon and into this evening. Post-frontal cloud cover is gradually eroding across SE TX/SW LA, and this will continue over the next few hours, with lingering clouds over south central LA following suit through the evening and overnight. Slightly cooler but much drier air will continue to filter into the region in the wake of the CDFNT as SFC high pressure builds into the Sabine River Valley, with low temperatures tonight/SUN morning expected to be the coolest of this forecast, ranging from around 50 across interior SE TX and Central LA to the mid/upper 50s near the coast. Temperatures will warm nicely after daybreak amid full sun as the SFC high traverses the area and a low/mid level shortwave ridge slides overhead. Highs in the lower/mid 80s are expected. The SFC high will depart to the east during the evening, with a light SE return flow becoming established, ushering in higher dewpoints, increasing cloud cover overnight, and more notably, warmer temperatures SUN night.

Long Term - Monday through Saturday
High pressure aloft will weaken on Monday and a deeper east to southeast flow is expected for early next week. For now, believe Monday will be dry as approaching front is forecasted to slow its progress into the Arklatex. For Tuesday, front is expected to be close enough to trigger mainly late day showers and thunderstorms. Additional showers and thunderstorms are expected on as the front slowly shifts south on Wednesday and enhanced troughing occurs over the western Gulf.

The front is expected to stall over the northern Gulf late in the week and weaken. Another front will approach on Friday night so will slightly increase rain chances ahead of the boundary on Friday.

Temperatures next week will be near or just above normal.
