Synopsis for pascagoula to atchafalaya river out 60 nm -
high pressure will remain across the local waters through midweek allowing for favorable marine conditions across the region. Winds have started to transition to a more southeasterly direction this afternoon as the high moves east of the region. Going into the weekend, pressure gradient will tighten again leading to the need for cautionary headlines or small craft advisories.

New SHORT TERM, LONG TERM, MARINE

SHORT TERM
(This evening through Wednesday night)
Issued at 145 PM CDT Tue Apr 23 2024

Under sunny skies and a zonal/progressive upper flow regime, temperatures have warmed across the region. With the surface flow veering to a more onshore flow with the surface high departing stage east, some better low level moisture has started to creep northward back into the area. This will limit critical fire weather concerns this afternoon.

Overnight, the upper level flow will transition to a dry northwesterly flow and a surface front will make an attempt to near the region. Although low level moisture influx has been weak, there is still a weak SREF signal for lower visibilities, especially across southwest Mississippi, where some shallow fog isn't out of the realm of possibility, especially if some moisture pool develops ahead of a stalling front just upstream over central MS/AL.

On Wednesday, outside of some scattered high clouds, the story will be temperatures (and that isn't even much of a story). With a continuation of increasing heights, temperatures should continue to increase gradually...both MaxT's and MinT's. (Frye)

LONG TERM
(Thursday through Monday night)
Issued at 145 PM CDT Tue Apr 23 2024

The long term period starts with the stalled front just to our north and east. Again, ahead of the front there could be some morning fog, however, as pressure gradient tightens between a high to our east and a strengthening surface low over the high plains, this will become less of a concern late in the week. The northwesterly flow on the eastern periphery of a ridge axis over Texas will eventually transition to a southwesterly flow by Friday as a strong H5 trough begins to amplify over the central plains.
This trough will suppress the upper ridge across the Gulf of Mexico...as such the heights and thicknesses will increase across our region allowing for the warming trend to continue before balancing out later in the weekend or early next week.

A cold front stalls upstream early in the weekend close to the Sabine River and ArkLaTex region. This will likely keep most rain chances up that way this weekend. A strong mid and upper level impulse amplifies and takes the same path roughly as the prior weaker impulse. This feature looks to move the aforementioned stalled frontal boundary eastward toward our area early next week.
As it does, we'll likely start seeing an uptick and scattered showers and thunderstorms, especially across our western tier counties/parishes late Monday or early Tuesday. Still low confidence in timing and precip probs, but we'll fine tune going into the weekend. (Frye)



AVIATION
(18Z TAFS)
Issued at 1237 PM CDT Tue Apr 23 2024

Mostly VFR conditions through the cycle. MCB may experience some shallow fog dropping VIS to IFR around sunrise, but this should dissipate rather rapidly after sunrise. Otherwise, winds will remain light and variable through the forecast. (Frye)

MARINE
Issued at 145 PM CDT Tue Apr 23 2024

Fairly benign marine conditions early on in the forecast period.
Onshore flow is anticipated to develop and gradually strengthen through the week. During the afternoons, winds could be enhanced over the MS Sound and Tidal Lakes. May need short fused Cautionary headlines or even SCA if the forecast trends up even just slightly. The pressure gradient increases on Friday and through the weekend where Cautionary headlines and/or SCAs look to be a safe bet across the local waters. (Frye)
