Synopsis for pascagoula to atchafalaya river out 60 nm -
surface ridge will remain centered east of the local marine waters through much of the week. That'll keep onshore flow well established. Speeds start off quite light early in the period. Towards the 2nd half of the week, an approaching cold front will cause a gradual increase in wind speeds with shower/storm chances increasing Thursday and especially into Friday and parts of the upcoming weekend.

SHORT TERM
(This evening through Tuesday night)
Issued at 131 PM CDT Mon Apr 28 2025
Starting out with this afternoon, it's quiet! But a bit warm/hot with many areas well into the mid to upper 80's. We'll top out around there today then see the Cu field dissipate as we decouple late afternoon into the evening hours revealing a pleasant, calm evening. Continuing to see mid-level suppression caused by the nearby high to our east, as evident by model soundings showing a strong dry subsidence inversion aloft causing compressional warming. This in turn has cranked up convective T's into the upper 90's which will keep a lid on rain chances not only for today but again tomorrow.
Main key item to look for will be the potential for some low clouds/patchy fog overnight tonight from around 09Z-13Z, as indicated by recent NBM ProbVis guidance and proximity model soundings illustrating plenty of surface to near-surface moisture, in conjunction with calm winds around daybreak. While chances remain rather low on the order of 15-30% for vis <3sm to 10-15% for vis <1sm, model soundings and low-level moisture profile provides a plausible idea of low clouds and/or tree-top fog producing VIS around 1-3sm, with greater probs from Baton Rouge to the Florida Parishes. Recent runs of the NBM have expanded some of these probs (albeit still low %) more east into the Atchafalaya Basin and Pearl River Basin, which makes sense given greater surface moisture trapped in these drainage basins along with calm winds to produce fog trapped in these "valleys" (loose term for Louisiana). Did add in patchy fog mention for these areas, down from Washington Parish/Pearl River Co down to around Slidell for a few hours early tomorrow morning but should quickly evaporate as we warm up fast around early/mid morning. Not anticipating dense fog issues at this time.
Tuesday will be rinse/repeat of today mainly, with another seabreeze/lakebreeze developing mid-morning but onshore SE winds will quickly press it north. Cu will develop by mid morning but coastal areas will again clear out late morning through the afternoon with no rain chances.
LONG TERM
(Wednesday through Sunday night)
Issued at 131 PM CDT Mon Apr 28 2025
Mid/late week, we enter the cusp of a steady transition in our upper-level pattern as the lingering upper-level low over the four corners region finally ejects east, helping to break down the 582dm ridge over the SE US. This impulse rides ENE into the ArkLaTex region while downstream of this trough at the surface, we see a weak surface low reflection providing plenty of lift in conjunction with ample moisture/instability to support thunderstorms from Texas into the Ohio Valley region. As the ridge breaks down with time, the aforementioned mid-level subsidence inversion weakens/moistens lowering convective temps, bringing back the afternoon storm chances yet again. Confidence is increasing that we'll see rain chances creep up on Thursday, as storms develop primarily in the afternoon hours, but will even higher on Friday as we get more support of the front into the area to "boost" storm coverage along with prime, moist and unstable conditions across the area. Based on pattern recognition alone, as high pressure builds into the Midwest following behind the surface low over New England, and with the front draped south across the immediate northern Gulf coast, dry air entrainment into the backside of frontogenetic/diurnally forced convection will lead to the risk for damaging winds/downburst in any stronger, potentially severe storms (GFS soundings valid for 18Z FRI indicate around 1000-1200J/KG of DCAPE right before storms develop).
Something to monitor as we've apparently peaked early into the "summertime" convective pattern what feels like a month early given the recent large-scale regime leading to very warm daily temperatures 5-10 degrees above average.
Beyond this into the upcoming weekend, it remains to be seen if the front can press far enough south to allow dry air to work into the region and dry us out or the front washes out keeping just enough moisture over the coast to provide daily afternoon storm chances. Keeping low PoPs due to uncertainty at this time, but can safely say chances are looking best along southern/coastal areas, particularly coastal SE LA and adjacent marine areas.
Something that we'll fine tune as we get closer.

VFR conditions are expected to prevail for all terminals this afternoon into the evening hours with SCT to periodic BKN CIGs in the 3-4kft range. Low CIGs will be possible mainly around daybreak Tuesday, generally from 09-13Z dropping flight categories to MVFR.
Some potential for some ground/surface fog as well from KMCB to KBTR that could drop flight categories slightly lower at times due to low VIS, but impacts are expected to remain limited with any ground fog being light. KLG
MARINE
Issued at 131 PM CDT Mon Apr 28 2025
Nearby surface high pressure to the east will continue to promote onshore SE, light winds through mid-week. This persistent fetch over time is expected to lead to a slow climb in seas for Gulf waters up to around 3-4ft with time, but winds will remain on the lighter side through most of the week. The next front and associated rain/storm chances increases Thursday, with greatest coverage/chances on Friday into Saturday, where a few strong to severe storms over marine waters will be possible. Main risks will be locally strong wind gusts to gale or stronger and waterspouts, along with dangerous lightning.
