Synopsis for pascagoula to atchafalaya river out 60 nm -
southeast winds of 5 to 10 knots will persist through Saturday evening, but a cold front will gradually shift winds to the north Saturday night into Sunday. By Sunday night, these northerly winds will strengthen to 15 to 20 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.

SHORT TERM
(Today through Sunday Night)
Issued at 300 AM CDT Fri Apr 19 2024
Initially, light boundary layer flow of 5 knots will allow for some boundary layer decoupling to occur over the next few hours, and a few areas of dense fog may form in the Pearl River region of the CWA before daybreak. The fog and low stratus will quickly clear within a couple of hours of sunrise as temperatures warm and the low level inversion lifts into a mid-level inversion layer. As temperatures warm into the 80s, low level instability will increase and some cumulus development is expected to take hold by late morning. However, a strong mid to upper level ridge axis will remain in control of the area today, and the subsidence associated with this will keep a strong mid- level capping inversion in place. Although temperatures will be warmer than average and some low level instability will be in place, this instability will be unable to overcome the capping inversion. The result will be largely dry conditions continuing with only a few sprinkles possible out of the deepest cumulus towers that form this afternoon. Overall, PoP remains low at 10 percent or less for today.
Tonight, the mid to upper level ridge axis will remain in control of the area, but a weak frontal boundary is expected to slip through Southwest Mississippi and into the Florida Parishes before stalling somewhere near the I-12 corridor. The movement of the front tonight will be nearly entirely driven by density differentials between a cooler and more dense airmass to the north and the warmer and less dense airmass to the south as there is no strong synoptic level feature pushing the front southward tonight.
Despite the passage of this front, the mid-levels will remain very dry to the continued subsidence aloft. This will keep a strong capping inversion in place and no rainfall is expected tonight.
Additionally, boundary layer winds will remain light and humidity values high, and this will support another round of low stratus and fog development over the region late tonight into early Saturday morning. Temperatures will also remain above average as high dewpoints and the blanket of cloud cover prohibit much in the way of cooling. Have opted to go with a blend of NBM 50th and NBM 75th percentile values for overnight lows. This keeps readings in the upper 60s and lower 70s.
The front will move very little on Saturday, but rain chances will increase by the late afternoon hours as the ridge axis shifts to the east and a fast moving shortwave trough slides through the region. A broad region of upper level ascent will combine with some very weak isentropic forcing over the slightly cooler airmass behind the front to induce some isolated to widely scattered showers and possibly a weak low-topped thunderstorm in the late afternoon hours Saturday. This will coincide with peak heating when temperatures are expected to rise into the upper 70s behind the front and the mid 80s ahead of the front.
Saturday night will see the front drift further south as rain cooled air from the shower activity to the north increases the density differential across the CWA Once again, there will not be a strong synoptic level forcing mechanism in place to drive the front offshore, so the front will gradually sink south and should stall somewhere near the Louisiana coast by Sunday morning.
Continued southwest flow in the mid and upper levels will continue to produce isentropically forced rain shower activity through the night, and a broad region of upper level positive vorticity advection developing over the area by late Sunday night should further reinforce the rainfall over the northern third of the CWA where overall forcing will be greatest. Temperatures will see a larger gradient as the combination of rain cooled air and weak cold air advection on the back of northerly winds pushes lows into the mid to upper 50s over Southwest Mississippi and the northern Florida Parishes. Lows will be warmer from I-10 southward with readings only cooling into the mid 60s.
Sunday into Sunday evening will be the most unsettled period of weather as a much stronger shortwave trough axis sweeps through the region. A weak mid-level low pressure system is expected to form along the I-20 corridor Sunday morning and then quickly push eastward through the day. This weak low will drive the front well offshore by Sunday evening, and much colder temperatures are expected across the entire region. Highs will only warm into the low to mid 60s over most of the region, and this will result in a broad area of isentropically induced rainfall impacting the region through the day on Sunday. Model sounding analysis indicates that mid-level lapse rates will be weak over the northern third of the forecast area, and do not have thunderstorm activity in place for this region. However, mid-level lapse rates are slightly more favorable for some isolated elevated convective activity from the I-10 corridor southward, and have this mentioned in the forecast.
As the trough axis and more favorable jet dynamics shift to the east Sunday evening, increasing subsidence aloft will take hold and lead to rapidly drying conditions from west to east through the evening hours. By late Sunday night, any rainfall will be well offshore and skies will being to slowly clear as a drier and cold airmass moves in. Lows will be much colder with readings dropping into the upper 40s and lower 50s.
LONG TERM
(Monday through Thursday)
Issued at 300 AM CDT Fri Apr 19 2024
Deep layer northwest flow aloft on Monday will continue to usher in a dry, stable, and cooler than average airmass into the region.
Skies will remain clear and temperatures will be below average in the lower 70s. Lows Monday night will cool back into the upper 40s and lower 50s as the combination of light winds and clear skies supports strong radiational cooling.
Tuesday will see a weak and moisture starved shortwave trough move through the region on the back of developing zonal flow.
Other than some scattered cirrus, there will be no evidence of this system moving through the area. Temperatures will gradually modify as the surface high shifts to the east and 925mb temperatures climb. Highs will warm into the mid to upper 70s on Tuesday and lows will be a good 10 degrees warmer Tuesday night with readings in the upper 50s and lower 60s. Conditions currently look favorable for another round of radiation fog development late Tuesday night into early Wednesday morning.
Although a strengthening ridge axis over Texas will be the primary influence on the forecast on Wednesday, a shortwave trough riding over the ridge could push a frontal boundary close enough to the northern CWA to spark off some isolated showers and thunderstorms during the afternoon hours. Any convective activity will be highly conditioned on the ability to break a fairly strong mid-level capping inversion, and have only went with 20 percent PoP due to this. Highs will continue to warm as onshore flow strengthens and expect to see temperatures climb into the upper 70s and lower 80s. Lows Wednesday night will be little changed with readings falling back into the upper 50s and lower 60s and another round of patchy radiation fog will be possible.
By Thursday, deep layer subsidence will take hold as the ridge axis over Texas shifts to the east and moves directly over the forecast area. A strong capping inversion will keep rain chances at bay even as a scattered cumulus field develops in the afternoon hours. This cumulus field will be driven by ample low level instability being fed by temperatures warming into the low to mid 80s.
AVIATION
(06Z TAFS)
Issued at 300 AM CDT Fri Apr 19 2024
A gradually strengthening inversion layer has allowed for ceilings ranging from 800 to 1500 feet to develop at several of the terminals in the past few hours. As the inversion further deepens, ceilings of 300 to 500 feet and lower visibilities of 3 to 5 miles is expected to take hold at MCB, BTR, HDC, and ASD. The inversion will quickly lift after 14z and return to MVFR and VFR conditions is expected at all of the terminals.
MARINE
Issued at 300 AM CDT Fri Apr 19 2024
Through Saturday night, winds will be largely from the southeast at 5 to 10 knots and seas of 1 to 2 feet can be expected as high pressure to the east dominates. However, a cold front will start to move through the waters on Sunday, and this will shift winds to the northwest at 10 to 15 knots by Sunday evening. Winds will further intensify to between 15 and 20 knots Sunday night into Monday as colder air advects over the warmer coastal waters. This will briefly raise seas to 3 to 5 feet by Monday morning. A high pressure system will pass directly over the waters Monday night into Tuesday and winds will shift to the northeast and then southeast over this period. Wind speeds will also drop to 10 to 15 knots as the heart of the cold pool shifts to the east. Southeast winds will then persist on Wednesday and Tuesday at 10 to 15 knots as high pressure slides into the eastern Gulf.
