Marine Weather and Tide Forecast for Belle Chasse, LA

LONG TERM
(Sunday night through Friday)
Issued at 257 AM CST Sat Dec 7 2024

A few disturbances will move over our area as a new front begins to move east out of the plains late Sunday into Monday. This will be the time of heaviest rainfall associated with this system, Sun night into Mon. As the cold front catches up with the upper jet, they will help each other in producing a new line of rainfall, but will be progressive by this time, which should be Monday night into Tuesday.
This additional accululation would not normally be an issue, but the area will have been saturated in many locations and any additional on Tuesday could be an issue as well. These type of systems are sluggish and slow which is the reason they produce a lot of training, but the good thing is they are not coupled with a sfc front or trough, so the severe wx is held to a minimum. But this coupling does occur as the front moves to the eastern portion of the area late Tue. Totals of 3 to 4 inches with isolated higher amouns will be possible from Sunday through Tue. Depending on where the H3 jet sets up and slowly creeps eastward, will decide which areas get the most precip. Once the front moves through, strong winds will carry CAA and DAA along with it bringing highs back into the 50s by Wed and Thu and freezing temps for northshore areas for Wed night and Thu night. A warming trend should take hold by the end of next week as we move up and down the thermal roller coaster.
