Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion Bay: GMZ400
325 AM CST Thu Jan 28 2021

Blustery offshore flow will gradually diminish through today as a Canadian high pressure system builds over the region. An onshore flow will return by Friday night as the high moves off to the east. A few showers are expected late Saturday into Sunday morning, ahead of and along the next cold front that will move through early Sunday. Another round of elevated northerly flow will build over the northwest Gulf of Mexico behind the front for early next week.
Area Forecast Discussion
National Weather Service Lake Charles LA
510am CST Thu Jan 28 2021

Early morning surface analysis shows high pressure over the upper Mississippi Valley ridging swd and providing a cool nrly low-level flow over the forecast area. Water vapor imagery shows the area under a wnwrly flow aloft between a departing trough nearing the Atlantic Coast and ridging entering the Plains States. Satellite imagery shows a bit of cirrus flowing past the region which, along with the stubborn nrly surface winds, have kept temps in the upper 30s/lower 40s for most of the forecast area. With regional 00z soundings showing very low PWAT/MRH values, not surprisingly area 88Ds are PPINE.

No significant changes are on tap with this morning's forecast. Our antecedent dry and cool conditions look to linger through tonight thanks to the Canadian high building past the region along with ridging to our west keeping a nwrly flow in place aloft. We will continue to see cirrus streaming overhead which will keep the area from seeing completely sunny skies as well as maybe holding temps down a degree or two with highs expected to run through the 50s this afternoon. Much of the forecast area will see lows in the 30s tonight with possibly a location or two touching the freezing mark, mainly over the far nern zones. As the high pushes to our east and a serly low-level flow develops off the Gulf, temps will warm to a more seasonal lower 60s for Friday.

The initial rain chances for this forecast period come on Saturday as moisture begins to pool on the increasing southerly flow ahead a storm system advancing across the Desert SW. As lift begins to overtake the region, expect showers to begin developing with best rain chances expected in the vicinity of the associated surface cold front expected later in the day on Saturday and Saturday night. At this time, instability looks lacking for any real thunderstorm development with this activity. A few stragglers look possible over lower Acadiana first thing Sunday morning before all precip comes to an end for the forecast area.

Surface high pressure and nwrly flow aloft will usher in another round of drier and slightly cooler weather for the early part of next week before our progressive pattern ushers in our next storm system and rain chances for the very end of the forecast period.

Marine Discussion
Issued a Low Water Advisory for the inland lakes/bays for this morning's low tide cycle as progs indicate water levels will get close to or exceed criteria (Sabine Lake looks to be the biggest question mark with levels not quite getting to criteria, but it could be close). Otherwise headlines for elevated winds/seas remain on the coastal waters through mid-morning when conditions begin to relax with the approach of high pressure.
