Synopsis for pascagoula to atchafalaya river out 60 nm -
southeast winds of 5 to 10 knots will persist through this afternoon, but a cold front will gradually shift winds to the north tonight into tomorrow. By tomorrow night, these northerly winds will strengthen to 15 to 25 knots and then linger into Monday. By Monday night, high pressure moving over the waters will allow the winds to relax back to 10 to 15 knots and also shift winds to the northeast and eventually southeast. These southeast winds of 10 to 15 knots will then remain in place into the middle of next week.

New AVIATION

UPDATE
Issued at 816 PM CDT Sat Apr 20 2024

Primarily cleaned up temps and PoPs with this update. It looks like after a brief perk up showers and weak storms around 00 UTC things are fizzling again right behind the slowly sinking southward boundary. Already near 60F up in New Roads and McComb behind this front and we should see temps fall overnight across the northern half of the area as the front passes through. Light to moderate rain will be prevailing to kick off early morning hours as the stratiform rain and convection leftover from southeast Texas makes its way into the area.

SHORT TERM
(This evening through Sunday night)
Issued at 349 PM CDT Sat Apr 20 2024

A fairly broad upper level trough is currently moving east through the Great Lakes. The southern side of this feature is relatively flat at this time which is why the associated cold front draped across central Louisiana and southern Mississippi is struggling to make southward progression. The cold front will be basically crawling south in the CWA this afternoon. Visible satellite hasn't changed much from this morning and shows only partly cloudy skies south of the boundary across the Florida Parishes and coastal Mississippi. This has allowed for decent warming which should increase CAPE in the lower to mid levels. As that boundary reaches this region later this aftn, a few thunderstorms could develop along and north of I-12 in LA and southern portions of LA. Latest CAMs show various versions of this and am in agreement with this.
Severe potential not particularly high due to weak shear but fairly steep mid level lapse rates could be enough for a few marginally severe storms with hail.

A shortwave on the backside of the northern trough is moving on a much farther south trajectory and will be passing through the mid to lower Mississippi Valley Sunday afternoon. This is what'll be needed to finally drive that cold front completely through the CWA on Sunday morning. Ample moisture in place with lift from the front will be a good setup for increasing showers. Model soundings continue to show minimal instability anywhere throughout the column.
Thus, thinking it'll be fairly tough for much thunder to develop and therefore now only have isolated thunderstorms in the zone forecasts. Overall QPF shouldn't be impactful generally speaking with areal amounts under an inch. Coverage forecast of 80% could still be too low.

MEFFER

LONG TERM
(Monday through Friday night)
Issued at 349 PM CDT Sat Apr 20 2024

This cold front won't be particularly strong being that a shortwave it driving it, so only looking at a day (Monday) of below normal temps with moderating conditions quickly returning as well as above normal temps Tuesday onward. Precip forecast still looking generally dry with zonal flow transitioning into ridging. That'll be supportive of current moderating temps expected.

AVIATION
(06Z TAFS)
Issued at 1139 PM CDT Sat Apr 20 2024

Frontal boundary has crossed southern terminals with winds now prevailing out of the north at around 10 knots. Some gusts upwards of 20 knots will be possible later this morning into early afternoon. MVFR CIGs are gradually building in, IFR likely for most sites over the coming hours as -RA enters the area. Some TSRA impacts are now expected to cross areas just north of BTR and impact MCB by 0630 UTC. Some TS impacts cannot be ruled out elsewhere overnight, but should be intermittent and limited. RA will gradually wane through late morning and CIGs will improve into the early afternoon. VFR conditions expected to prevail at all terminals by 00 UTC Sunday evening.

MARINE
Issued at 349 PM CDT Sat Apr 20 2024

A surface high pressure is centered in the western Atlantic and extending across the Gulf of Mexico. The western periphery of this ridge is being broken down by approaching surface trough to the north of the area. Thus, onshore flow is weakening with most of the coastal waters staying light and variable until a cold front comes through early Sunday morning. Cold air advection won't be particularly strong with this boundary and thus likely only looking at about 12 to 18 hours of low-end Small Craft conditions.
