Synopsis for pascagoula to atchafalaya river out 60 nm -
surface ridge will remain centered east of the local marine waters through much of the week. That'll keep onshore flow well established. Speeds start off quite light early in the period. Towards the 2nd half of the week, an approaching cold front will cause a gradual increase in wind speeds with shower/storm chances increasing Thursday and especially into Friday and parts of the upcoming weekend.

New AVIATION
UPDATE
Issued at 925 AM CDT Mon Apr 28 2025
Performed a brief gridded forecast update this morning to bring in short-range guidance matched with obs/trends. We're on the path to another nice and warm day across the area. The 12Z KLIX sounding illustrated a prominently dry tropospheric profile aside from the lowest PBL showing plenty of low-level (surface to near-surface) moisture. We'll continue to mix out today starting with low clouds/low LCL heights this morning, but will rise as we warm up at the surface through the afternoon providing plenty of Cu given low-level moisture (already seeing on GOES-16 VIS trends). Greater mid-level suppression thanks to the nearby high to our east is expected to keep a lid on convection today yielding a stronger H8-H5 mid-level subsidence inversion causing Tc to rise to around the upper 90's to even lower 100's keeping rain chances right around zero for today.
Increasing land/sea temp differental later this morning will support the development of a sea/lake breeze boundary, but persistent SE surface and 0-1km ML wind from 8-12kts will press this inland quickly, potentially leading to coastal areas clearing out earlier.
No adjustments to highs needed as temperatures remain on track and guidance is looking confident overall. Will dive deeper as we always do with the afternoon package coming in a few hours. KLG
SHORT TERM
(Today through Tuesday)
Issued at 245 AM CDT Mon Apr 28 2025
The heat will build over the next few days. This won't be July/August type of heat yet as temps will only find their way to around 90F. One of the reasons for the higher temps is there will very little in the way of rain around the area for the next few days.
LONG TERM
(Tuesday night through Sunday)
Issued at 245 AM CDT Mon Apr 28 2025
Highs near or at 90F will continue into Thu but temps will begin to fall toward the weekend as more cloud cover is generated. There will be more sh/ts around starting Thu which but will likely be late in the day. A front will move into central TX and stall Thu while another front moves in from the north and stalls near the LA/AR line Fri. Disturbances will ride along and leave these boundaries by the end of the week keeping rainfall probs high over the area with the possibility of some of these being strong/severe. Most of this activity will be diurnally driven through the weekend.
AVIATION
(18Z TAFS)
Issued at 1157 AM CDT Mon Apr 28 2025
VFR conditions are expected to prevail for all terminals this afternoon into the evening hours with SCT to perioic BKN CIGs in the 3-4kft range. Low CIGs will be possible mainly around daybreak Tuesday, generally from 09-13Z dropping flight categories to MVFR.
Some potential for some ground/surface fog as well from KMCB to KBTR that could drop flight categories slightly lower at times due to low VIS, but impacts are expected to remain limited with any ground fog being light. KLG
MARINE
Issued at 245 AM CDT Mon Apr 28 2025
High pressure will be centered directly over or just to the east of the waters through Wed which will result in light winds of around 10 knots and seas of 1 to 3 feet on average. Winds will begin to rise to around 15kt by Thu but should remain less than 20kt through the end of the week outside any storms.
