Synopsis for pascagoula to atchafalaya river out 60 nm -
a broad area of high pressure will remain over the eastern gulf through the weekend and into early next week. This will allow for a persistent onshore flow of between 10 and 15 knots through the period with locally higher gusts through the start of the weekend mostly offshore. A cold front will then move through the waters on Wednesday. This front will shift winds to the northwest by Wednesday night. A few Thunderstorms will also accompany the front as it moves through on Wednesday, and this could lead to some locally higher winds and seas in close vicinity to the storms.

New AVIATION

SHORT TERM
(This evening through Sunday night)
Issued at 221 PM CDT Fri May 16 2025

A persistence forecast package is in place for today as the region continues to see a deep layer ridge axis be the dominant feature through the weekend. There will be some weakening of the ridge tomorrow as a northern stream trough passes through the Midwest, but a continued strong capping inversion in the mid-levels will prohibit deeper updrafts from developing. At most, a very isolated shower or thunderstorm may develop in southwest Mississippi tomorrow afternoon where the capping inversion is expected to be weakest. Additionally, if an updraft is able to punch through the cap and develop a storm, it could turn strong and produce some gusty winds as drier air aloft and steep low level lapse rates beneath the inversion support a higher than average downdraft potential. Elsewhere, the same conditions observed today can be expected for both Saturday and Sunday. Morning cloud cover that forms beneath that mid-level inversion will mix out to a mostly sunny sky by the late morning and early afternoon hours. Dewpoints will remain in the low to mid 70s, and highs will easily warm into the upper 80s and lower 90s with the hottest temperatures inland and away from any coastal influences.

LONG TERM
(Monday through Thursday night)
Issued at 221 PM CDT Fri May 16 2025

Conditions on Monday will remain the same as those seen this weekend as the deep layer ridge over the Gulf South continues to be the dominant weather feature. Morning clouds and lows in the low to mid 70s will give way to mostly sunny skies and highs in the upper 80s and lower 90s. Monday night will see similar conditions with another round of cloud cover forming after midnight.

Tuesday into Wednesday will be a more transitional period of weather as the ridge axis over the area finally begins to shift to the east in response to a deepening longwave trough over the Plains states. This deepening trough will drive a cold front through the forecast area Tuesday night and Wednesday, and just enough moisture return into the mid-levels should be sufficient to produce some scattered shower and thunderstorm activity Tuesday night into Wednesday. Any convection should be confined to the front itself and rainfall will generally be short-lived with QPF of less than a quarter of an inch expected. Fortunately, shear profiles are not supportive of any strong to severe thunderstorm activity as the front moves through the area.

Temperatures will remain warm ahead of the front with highs climbing back to near 90 degrees on Tuesday. However, a surge of cooler air on the back of a deep layer northwest flow pattern will advect into the region on Wednesday and Thursday. Highs will fall back closer to average on Wednesday and should fall to slightly below average in the upper 70s and lower 80s by Thursday. A much drier airmass will also move in and this will push dewpoints from the lower 70s down into the 50s on Thursday. With largely clear skies and lighter winds in place by Thursday night, lows will easily dip into the upper 50s and lower 60s resulting in a refreshing break from the recent heat.

AVIATION
(06Z TAFS)
Issued at 1151 PM CDT Fri May 16 2025

A stratus deck is building in with overnight cooling temperatures. Any locations that are still at VFR will change over very soon to MVFR. MVFR conditions at all terminals could degrade further with ceilings at or just below 1000 feet. At MCB the stratus build down will merge into a light fog situation from around 12 to 14Z with visibilities dropping to around 4SM. By 14 to 15Z the temperature inversion will begin to mix out giving improving conditions as the stratus deck breaks up and lifts.

MARINE
Issued at 221 PM CDT Fri May 16 2025

A broad surface high pressure system centered over the eastern Gulf will keep a persistent onshore flow regime in place through Tuesday. Winds will range from 10 to 15 knots and seas of 2 to 4 feet are expected through the period. On Wednesday, a cold front will push through the coastal waters. Winds will turn more westerly and then northwesterly through the day and some scattered thunderstorm activity will accompany the frontal passage. These thunderstorms could produce some locally gusty winds as they move through. Other than that thunderstorm threat on Wednesday, a very benign stretch of weather is anticipated for the coastal waters.
