Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion Bay: GMZ400
357 PM CDT Sun Oct 25 2020

High pressure ridge will continue to weaken over the Gulf coast states. This will allow for easterly flow across the waters through Tuesday. Tropical Storm Zeta will move into the Gulf on Tuesday potentially as a hurricane. This system along with a cold front will bring increased offshore flow for late in the week. MAriners should continue to monitor the latest forecasts for Zeta.

.Short Term (Tonight through Monday night) Main forecast issue will continue to be temperatures and cloud cover. Expect cloud cover to continue tonight as model soundings show good inversion over the area. Surface ridge is forecasted to weaken tonight and Monday. Easterly flow is expected to provide better mixing so believe there will be more breaks in the clouds especially over Acadiana area. For now, may go a little lower than guidance on temperatures for Monday. Lows will be mainly in the 60s Monday night. Dry weather is forecasted through this period.

Long Term - Tuesday through Sunday
Rain chances will increase Tuesday due to a couple factors. First, a cold front and upper level low/trough will move through the area Wednesday night. Also Zeta may feed additional moisture as well. For now, will have highest POPs Wednesday and Wednesday night. Will of course be monitoring Zeta. The current track forecast has it making landfall well east of the area but a more westward track could certainly provide impacts to south central Louisiana.

After the passage of the front, cooler and drier weather is forecasted beginning Thursday and continuing through the weekend. Low temperatures through the period will be mostly in the 40s.

Marine
With high pressure ridge weakening, easterly flow will develop on Monday and continue through Wednesday. The track of Zeta will maintain easterly flow through Wednesday and may bring winds to tropical storm force, especially well offshore from Vermilion Bay. The cold front will move through the area Wednesday and Wednesday night. Moderate to strong N/NW flow is expected.
