Synopsis for pascagoula to atchafalaya river out 60 nm..
gusty easterly winds in excess of 20 to 25 knots will continue today, which will maintain hazardous seas for small craft of 4 to 7 feet. Winds will gradually decrease ahead of a pattern change and approaching cold front which is expected to arrive Saturday. An increase in winds to 20 to 25 knots is expected behind the front then easing into the first of next week.

New AVIATION
UPDATE
Issued at 1049 AM CDT Tue Oct 3 2023
Surface obs show a fairly sharp gradient of low level dry/moist air right along the LA coastline. PW's are too low to support convective development over most of the CWA, but there are a few showers on radar in coastal waters and nearby parishes where dewpoints are still in the 70s. Thus, have updated POPs to reflect low end potential for showers and maybe a storm or 2 in the regions mentioned above.
SHORT TERM
(Today through Wednesday)
Issued at 251 AM CDT Tue Oct 3 2023
High pressure remains dominate over the area and this will remain the case through at least Wed. A few showers could tickle the coast from time to time with moisture loading ahead of a strong cold front moving toward the area Wed. As expected, the GFS has backed off of bringing these showers into the area from the gulf for Wed. There will be more showers and maybe a storm or two over the coastal waters though. Will reissue the coastal flood advisory for tonight, tide levels will be about the same as they were this morning and we will begin to fall from this spring tide cycle after Wed night bringing these levels lower after that.
LONG TERM
(Wednesday night through Monday)
Issued at 251 AM CDT Tue Oct 3 2023
Global models continue to show bridging of the cold front as it moves toward the area. This would cause the line of sh/ts along the front to begin decaying before it gets here. Even though there could be several areas of showers existing along and ahead of the front, no large rain amounts are expected that could be drought busting. Cloud cover should be the most prevalent thing noticed.
The high that is over the area currently will get forced east and NE, slowly giving way to the new high moving in, but the old high will take its time in moving which should keep most of the moisture loading showers near the coast Thursday while the best forcing will be with the front as it moves through which will give the best chance(albeit low chance) of rain Friday. The driest model this time is the GFS as compared with the Euro and so the flip flopping continues. But this same relatively dry scenario is kept each run, its just showing up in a different model each 24hrs. The more synoptic feature that all models agree on is the cold front actually moving through the area, although timing is different with each. But they do show two boundaries. The first moving in Thu night and slowing over the area which will barely be noticeable with exception to a few showers, cloud cover and a light northerly brz. Then the main "real" cold front moves through Fri night or Sat morning cleaning the area and bringing the coolest air so far this season. Yeeeeeeeesssssss, it will be a nice change and some of the northern portion of the area c could get into the upper 40s for lows by Sat night. But better yet, the highs Sat may struggle to get out of the 70s inland, the coast may still see some low 80s though.
AVIATION
(18Z TAFS)
Issued at 1222 PM CDT Tue Oct 3 2023
No significant impacts expected at terminals through this forecast period. A CU field has developed across portions of the area with ceilings just nudging into MVFR category. Those will probably rise into VFR before eventually dissipated later today. Easterly winds persist with most terminals 5 to 10 knots with gusts to 15 knots. TAF sites closer to water will experience about 5kts stronger than that during the day. Evening and nighttime hours return to light and variable with mostly VFR prevailing. Some guidance suggest low chance for light fog Tuesday morning at KMCB and KBTR. Not confident enough to add that to TAFs just yet.
MARINE
Issued at 251 AM CDT Tue Oct 3 2023
We will continue the small craft advisory as winds continue to move in and out of criteria around 20kt. These winds may be present in the western most zones again tonight but after that all marine areas should fall to caution statements or no headlines. Winds should be weakest Thu and Fri but a strong cold front is advertised to move through the northern gulf causing moderate northerly winds around 25kt possibly as early as Friday night or Saturday morning.
