Synopsis for pascagoula to atchafalaya river out 60 nm -
high pressure well to our northeast and a deepening surface low along the lee side of the rockies is helping build winds across the local waters. A surface low will develop today and deepen as it moves across the plains and into the upper mississippi valley on Sunday. Additionally, the high over the western portions of the atlantic will slide south and become centered east of the carolinas. This should maintain or even strengthen the gradient across the area leading to additional strong southerly winds. This will keep small craft advisory conditions in place through Sunday night. Also, the persistent southerly flow will produce a large fetch across the gulf with seas likely higher than typical as long swell develops.

SHORT TERM
(This evening through Monday night)
Issued at 338 PM CDT Sat Apr 27 2024
Generally speaking, upper level ridge is in place across the eastern third of the country and an upper trough covers the rest of the country. The CWA is currently on the western side of the ridge.
Steadily onshore flow has brought in quite a bit of low level moisture with dewpoints in the mid 60s to lower 70s. Due to this and NBM being slightly too cool last night, went ahead and bumped up overnight lows slightly. That'll give us a warm start to Sunday with most locations having lows around 70 degrees. Model soundings show PW's still quite low, not much over 1", except for along the MS coast. It's here that slightly higher column moisture as well as moisture convergence along the coast combined with diurnal heating will allow for scattered showers to develop. Based on this and agreement from global models, have increased the areal extent of last night's forecast rain on Sunday.
A bit more complex setup looks to develop on Monday related to the upper level trough currently draped across the Rocky Mountains.
Models show the base of this trough rotating northeast Sunday with a closed low moving through the upper Mississippi Valley Monday. At the same time, a piece of energy breaks off the southwestern side of the trough and heads due west towards the Lower Mississippi Valley.
It's this shortwave that'll initiate stronger convection in north Louisiana Monday morning. All the CAMs, and even the global models, show an MCS developing there, cold pooling and diving southeastward.
The 2 questions are what's its actual trajectory going to be and how strong will it be when it gets closer to the Gulf Coast. Model soundings show sub-severe wind shear but more than ample CAPE.
That's completely expected with a weak shortwave driving the show and late spring temps in place. Thus, think timing will play a big factor in if the MCS is able to capitalize on instability in place.
How soon it starts to cold pool will be a big factor on if it dives south across southwest LA or southeast LA and southern MS. Thus, SPC's marginal outlook is quite appropriate for this potential event.
LONG TERM
(Tuesday through Friday night)
Issued at 338 PM CDT Sat Apr 27 2024
Tuesday sees us right in the middle of upper level northern and southern flows with very gentle troughing over the western CONUS and weak ridging over the eastern Pacific across northern Mexico and into the northern Gulf. At the surface we have the Bermuda high in the western Atlantic and low pressure over the western US down into Mexico. Several shortwaves move through the upper levels as the week progresses, drawing moisture into the area and giving us several chances for rain. The greatest chance is on Tuesday with PoPs around 50% and forecasted amounts generally around 1/3 of an inch. It doesn't look like any severe weather will accompany the rain. Temperatures start a bit above normal with lows in the mid- 60s to low 70 and highs in the low to mid 80s. By the weekend we are looking at highs in the mid to upper 80s. Winds should be out of the south to southeast and 10-15mph.
AVIATION
(06Z TAFS)
Issued at 1203 AM CDT Sun Apr 28 2024
Strong east-southeasterly flow will continue to impact all terminals for the entire forecast period as a low pressure deepens across the central US. Winds will shift slightly more southeasterly as the approaching cold front get closer towards the end of the period. Low-level moisture advection ahead of the front has caused some patchy MVFR ceilings this evening and will continue into the morning before daybreak. Once the sun comes up, those low ceiling should break up and VFR conditions return for the rest of the period.

Issued at 338 PM CDT Sat Apr 27 2024
A surface ridge centered in the western Atlantic Ocean just off the East Coast. It'll remain there throughout the forecast period.
That'll keep onshore flow entrenched. The local pressure gradient between that feature and deepening low in the Central Plains has increased winds and seas/waves into Small Craft Advisory. Expect those conditions to persist through this weekend. Have made a 12 hour extension to the advisory based on latest forecast winds.
Otherwise, a slight weakening in the gradient will allow for winds to fall into Exercise Caution next week.
