Synopsis for pascagoula to atchafalaya river out 60 nm -
more dense sea fog can be expected tonight along immediate coastal waters, especially the sounds near the mississippi coast. Southeasterly winds will strengthen through Tuesday as a low pressure system passes through the waters. Small craft headlines for winds gusting to 15 to 25 knots could be warranted for waters extending 20nm from the coast and beyond. Light easterly winds can be expected at midweek behind the low pressure. By Friday, winds will shift from easterly to southerly and strengthen once again ahead of another frontal system that should stall inland by the weekend.

SHORT TERM
(This evening through Tuesday night)
Issued at 308 PM CST Sun Mar 3 2024

KEY MESSAGES: 1. Patchy dense fog resulting in sudden drops in visibility to below a quarter mile is expected tonight across much of southeast LA and southern MS and 1 nautical mile or less across the immediate coastal shelf waters along the northern Gulf Coast.

2. Strong to severe storms capable of producing locally heavy rainfall, gusty winds, and hail are likely between late Monday night through Tuesday morning moving from west to east.

Looking at visible satellite imagery to start us off, we have gradually seen low stratus and fog break out into scattered cu areawide and a bit of agitated cu along the the Atchafalaya and into the Southshore this afternoon where we've seen some shallow showers.
Dew points remain in the mid to upper 60s with highs sitting in the upper 70s. Safe to say it's feeling a lot like spring out there with the humidity and warmth. This moist air mass will linger through tonight with southeasterly onshore flow funneling more developing sea fog inland over parts of southeast LA and southern MS.
Confidence is high in seeing dense fog during periods tonight across much of the area though there may be periods where visibility greatly improves in between waves of sea fog. Confidence is lowest for dense fog along the Atchafalaya basin currently, but regardless have issued a dense fog advisory areawide given the high confidence of impacts to visibility.

Gradual improvement in visibility and low stratus should occur after sunrise Monday morning and we should break out into a familiar cu field ahead of the approaching system. As the day progresses, the combination of increasing surface heating, elevated moisture, and increasing lift from an approaching shortwave trough ejecting out of northern Mexico will induce increasing shower and storm development across the coastal areas which will gradually spread inland during the afternoon and evening hours. By the evening hours, CAM guidance is honing on the existence of a theta-e gradient with deeper moisture extending up from coastal LA through the Atchafalaya basin that could allow the focus of more organized thunderstorm activity to develop. Given the unstable environment (>1500 j/kg MLCAPE, 67- 72F dew point temps), steep mid-level lapse rates (>7 C/km), and increasing wind shear ahead of the shortwave trough, cellular modes with more substantial updrafts could support severe thunderstorms with damaging hail and winds being the primary threat. While wind profiles and storm-relative helicity are weaker through the early afternoon, any surface vorticity generated along the gradient/a boundary that can induce stretching with the high 0-3km CAPE present could support a brief spin up thus tornado potential is non-zero along this corridor during Monday afternoon.

The severe threat quickly transitions to a heavy rainfall threat through Monday night and into Tuesday morning as congealing storms along this boundary interact with the approaching surface trough of low pressure expected to gradually coalesce along coastal LA.
Enhanced moisture convergence in addition to PWATs exceeding 1.7" (daily climatological max) and upper diffluence aiding mass evacuation in the exit region of the upper shortwave trough will make for highly efficient rainfall rates (2-4"/hr) with deeper convection that develops and exactly where this corridor of heavier rain sets up along the coastal areas will be crucial. Since yesterday, it appears confidence has increased regarding localized flooding potential but exactly where greatest impacts will be along and south of the I-10/12 corridor remains uncertain.

As this deeper convection congeals, a larger cold pool could develop on the backside in association with an MCS which could aid in pushing this convection offshore through midday Tuesday as the surface trough deepens east of our area. Thereafter, subsidence and drying should ensue allowing skies to gradually break up and clear through the evening and overnight hours. No formal front is associated with this system so our consolation is some slightly drier air and one day of nicer weather into Wednesday before we see moisture make its return later in the week ahead of our next system.

LONG TERM
(Wednesday through Saturday night)
Issued at 308 PM CST Sun Mar 3 2024

By this portion of the forecast period, Wednesday, shortwave that brings convection to the area Tuesday will be east of the Mississippi River Valley and steadily moving eastward. There may be lingering clouds and isolated sprinkles over the CWA on Wednesday morning on the backside of this system but current model runs depict a relatively weak upper low. If it happens to be deeper than latest model runs, that could occur and may need to add precip into the forecast for that timeframe. Otherwise, should be a warm day with highs several degrees above normal topping out around 80 degrees.

Weak ridging on the backside of the mid week trough will continue to support moderate temps on Thursday. A split flow upper level pattern on the West Coast will then phase together with the now amplifying trough moving east across the Rockies. As this system tracks closer to the Mississippi River Valley, moisture will surge north from the Gulf of Mexico. Model PW suggests values locally approaching 2" Friday morning. For context, sounding climatology shows the average PW this time of year to be near 1.7". As the trough approaches Friday, local cooling in the mid/upper levels and increasing low level moisture will result in atmospheric destabilization. At the same time, low and mid level winds will increase substantially with 850mb winds near 50kts and 500mb winds closer to 100kts. That'll bring shear values up to 30kts at 0-1km and 70kts at 0-6km. So with ample moisture in place, increasing shear and instability, could be looking at a decent chance for severe weather across the CWA
One chance from previous forecast is the timing of this event with model blends suggesting more impacts during the day Friday vs Thursday night. That would support at least a better chance for severe storms due to potential for daytime heating destabilization.

Once this system moves through, should be looking at a cooler weekend with rain ending early in this period.

MEFFER

AVIATION
(06Z TAFS)
Issued at 1136 PM CST Sun Mar 3 2024

In the last hour, have seen conditions start to deteriorate with only KMCB and KBTR above IFR at forecast issuance time. KGPT already near field minima, with most terminals expected to be at least occasionally at LIFR or VLIFR from around 09z to 13-14z.
Beyond that point, ceilings will improve to MVFR and visibilities to VFR. The threat of SHRA/TSRA will increase beyond 18z Monday, although through 00z Tuesday, the better threat of TSRA is probably going to be at KHUM/KBTR/KMSY/KNEW. After 00z Tuesday, rain will become more widespread with ceilings lowering to IFR, and potential for TSRA becoming more widespread. Later forecasts will likely focus timing and location of TSRA in a smaller window.
Once conditions deteriorate tomorrow evening, may not be much improvement until perhaps 18z Thursday.

MARINE
Issued at 308 PM CST Sun Mar 3 2024

Watching more marine fog creeping into the MS Sound this hour and further fog development can be expected through the evening and overnight hours. Dense fog could linger through the day Monday in some areas as deeper moisture streams over the cooler shelf waters. A dense fog advisory is posted and could be posted again for Monday night. Southerly winds around 10-15kt with gusts upwards of 20-25kt will become variable Tuesday then northerly late Tuesday. Winds will then move around the compass to easterly by Wed then onshore flow through the end of the week. Outside storms, winds will range from 10-20kt throughout the week.
