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 Saturday 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. Also, the persistent southerly flow will produce a large fetch across the gulf with seas likely higher than typical as long swell develops.

New SHORT TERM, LONG TERM, AVIATION, MARINE
SHORT TERM
(Today through Sunday)
Issued at 253 AM CDT Sat Apr 27 2024
Strong moisture loading into the stalling frontal systems in the foothills and plains causing strong spring breezes over our area is quite normal for this time of year before the easterlies win out and we move into the heat of summer. But while the westerlies are still active, we can still get some strong storms due to this battle. With the systems stalling to the west and the upper level troughing not making much advance, we will see these winds continue and possibly get a bit stronger. The normal dance of stronger winds over marine areas at night and over land during the day will also continue. Land gusts overnight should give a clue to what the sustained wind speeds will be during the daylight hours once mixed out. Some of these numbers are in the 18-23kt range this morning, so to see some sustained winds in and around 20-25mph with gusts to 30mph will be a good possibility today and possibly Sunday. We will post a wind advisory for today mainly for the frequent gusts 25+mph. The other headlines will remain as posted. Water levels will rise with these consistant winds and levels 1-2ft above normal levels should be the result. We will also bring precip numbers up a bit for the Pearl River and Mississippi coastal areas for Sunday. There is some evidence that as the trough out west budges just a bit farther east by tonight into Sunday that it will squeeze the western periphery of the sfc high to the east. This should cause a really good sfc convergence area over the gulf into our area for Sunday. This should be able to promote at least some showers during the early morning hours Sunday and possibly some deeper showers and even a strike or two of lightning with heating Sunday. The NBM mean is not showing this very well so it has been manually added to the fcast.
LONG TERM
(Sunday night through Friday)
Issued at 253 AM CDT Sat Apr 27 2024
This story will get old as fronts move as far east as Dallas and stall only to retrograde. This activity will continue to orphan the line of sh/ts that develop along the front. The line moves a bit farther east then dissipates as support is taken away. This will change a bit by Monday. Another line of sh/ts will move away from the frontal support but will not meet the same demise as the others.
The support will come from the H3 jet from the upper trough to our NW coupling with the strong almost zonal flow coming across the EastPac into Mexico and over the gulf. This will set up a strong split flow at H3 near our area and will move east with time Sun night and Monday. The upper trough will not move much farther east than the Arkansas/Louisiana area Monday. This means that as the area of divergence aloft moves east, it will eventually become weaker as it moves east of the Miss/Ala state line. And in turn, since this will be the support for th sh/ts that area moving east Monday, the sh/ts will also begin to weaken and decay. No frontal passage with these storms but they will offer some temporary cooling as they cold pool out. This could give our area some much needed rain as well.
But we will need to get closer to this time frame to see how much.
This frontal dance to the west will continue into the foreseeable future but the front may actually become oriented more zonally over Arkansas by the end of the upcoming week. This doesn't change a lot here, but sh/ts could move away from this front and give us a chance of rain from time to time by late next week.
AVIATION
(12Z TAFS)
Issued at 253 AM CDT Sat Apr 27 2024
A mix of VFR and MVFR cigs will become all VFR by mid morning and remain through the day. This will play out the same way again tonight with the same mix of VFR and MVFR cigs tonight into Sunday morning. Very breezy conditions(~15020G30KT) will exist for all terminals today but wind direction will be stable from SE.
MARINE
Issued at 253 AM CDT Sat Apr 27 2024
Strong SE winds(20-25kt) will remain over all marine areas through at least the next few days if not more. Small craft advisories have been extended for this reason. There will be some gusts to gale force, but this should be the rule most of the time. But this will be a high end advisory for all waters. Winds will remain out of the SE through this fcast but should ease just a bit as we move through the week.
