Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion Bay: GMZ400
600 PM CDT Wed Oct 27 2021

Strong gusty winds and elevated seas will be a concern across all marine zones through the end of the week as the pressure gradient overhead remains tight. Sustained winds around 20-25kts overnight tonight will increase to around 25-30kts tomorrow, with accompanying gusts upwards of 40kts possible. At the same time, seas around 5-8 feet with higher swells especially in the beyond 20nm waters will be possible. Winds will still be very breezy on Friday but will finally begin to relax Friday evening into early Saturday, falling to around 10kts by Saturday afternoon. Northwesterly flow will shift north, northeast and eventually eastward by the end of the weekend as high pressure settles over the SE US.

SHORT TERM [Today through 12Z Saturday]... A very robust weather pattern is ongoing across the CWA this afternoon as a strong low pressure system moves across the Lower MS River Valley. Across the western half of the CWA, rain is coming to an end this afternoon and skies are beginning to clear. On the other hand, the eastern half of the CWA, especially across Acadiana, will continue.nue to see strong thunderstorms through the next few hours as this storm system continues to propagate eastward. Looks like the potential for tornadoes has largely died off with the main concern continuing to be damaging straight line winds along and ahead of this squall line. The squall line will finally move out of the CWA through the next couple of hours, with the trailing stratiform rain coming to an end through evening hours shortly thereafter. Once the rain comes to an end this evening dry weather can be expected through the end of the short term period.

Tonight into tomorrow, strong northwesterly flow in the wake of today's cold front will bring a cooler and drier airmass into the region. Temps will fall through the evening and overnight hours, with lows expected to bottom out in the mid to upper 50s tomorrow morning. Tomorrow and Friday, afternoon highs will top out in the upper 60s to mid 70s, amid sunny skies, while lows will fall into the mid 40s to low 50s overnight. Only concern through the next couple of days will be strong gusty winds as the pressure gradient overhead tightens behind the departing low pressure system. Sustained winds around 15-20kts and gusts to around 25-30kts can be expected tomorrow especially through the afternoon. Winds will remain elevated into Friday, before gradually calming Friday night into the weekend.

Long Term - Saturday Through Wednesday
As we start the extended period, the area will remain under the influence of nwrly flow aloft behind the departing mid/upper-level low, while surface high pressure gradually builds ewd over the warning Gulf Region. The combo of all this will maintain our dry/cooler conditions through the weekend with near-seasonal lows in the 40s/50s and highs in the 70s.

By Monday, the high is forecast to push ewd past the forecast area, allowing a return flow to re-develop. The increasing southerly flow will allow a warmup to commence with temps pushing 80F that afternoon. A weak disturbance passing aloft will likely increase cloud cover, but forecast soundings indicate insufficient moisture to allow for any convective development. This pattern looks to continue into Tuesday at this time.

Rain chances return to the area for Wednesday as a mid-level shortwave pushing ewd toward the Mississippi Valley drags another front toward the region, while forecast soundings indicate better moisture in play. The enhanced cloud cover and precipitation should hold temps back a little with highs expected to run in the mid 70s for the bulk of the forecast area.
