New SHORT TERM, LONG TERM, MARINE
SHORT TERM
(Today through Thursday)
Issued at 310 AM CDT Wed Apr 23 2025
Shortwave moving eastward across Texas with upper ridging now well off the Florida coast. Some semblance of mid-level ridging to the west of the Texas shortwave. At the surface, the Bermuda high has a westward extension into the eastern Gulf. A stationary boundary was noted near Interstate 40. There is likely an outflow boundary from evening convection near or northwest of Baton Rouge and McComb. Temperatures at 3 AM CDT were mainly in the upper 60s and lower 70s, but ranged from 62 at Trent Lott Airport to 75 at Gulfport and Biloxi, which were being warmed by light southerly winds over waters from Mississippi Sound where water temperatures were in the mid 70s.
The Texas shortwave will move east-northeast across the area today and Thursday, while weakening somewhat. Precipitable water values that were near 1.5 inches last evening will dry out slightly over the next 36 hours to about 1.3 inches. There remains sufficient moisture and instability for the development of scattered thunderstorms, especially during the afternoon hours. The best environment for storms today should be across about the northern half of the area, from about the Interstate 10/12 corridor northward, with the remnant outflow boundary mentioned above as a possible focus for development. On Thursday, as ridging builds into coastal areas, convection may be limited to about the northwest third of the area, such as southwest Mississippi and the adjacent Florida Parishes of southeast Louisiana. Storms will continue to have the potential to produce locally heavy rainfall due to rather slow storm movement.
High temperatures should be primarily in the lower and middle 80s today and Thursday. Not much change in overnight lows, either, but did depart from the NBM numbers somewhat in Jackson County, where the Pascagoula River Basin drainage is producing somewhat cooler conditions than anywhere else.
LONG TERM
(Thursday night through Tuesday)
Issued at 310 AM CDT Wed Apr 23 2025
Ridging is expected to build across the western Gulf and southern Plains Friday and Saturday, and across much of the Mississippi and Ohio River Valleys over the weekend into early next week. This will help the airmass dry out somewhat, with precipitable water values falling off to around 1 inch for Friday through at least Monday before increasing slightly by Tuesday. Any thunderstorm development during that period looks to be isolated in coverage, if any develops at all. High temperatures are likely to be in the mid and upper 80s away from the immediate coast, where sea breezes may cap off heating at midday. Won't rule out a few spots reaching 90, perhaps on Sunday, although the 91 in the MEX numbers at PQL looks a little out of place unless there is an offshore wind.
Little day to day change in overnight lows.
AVIATION
(06Z TAFS)
Issued at 1143 PM CDT Tue Apr 22 2025
Mixture of VFR to MVFR and lower conditions is forecast for the period. The best chance for MVFR and lower will be overnight due to low ceilings and there is also a threat for fog as well. The overall ceilings will lift slightly during the day but chances of showers and storms will be in the forecast and but conditions would lower if a terminal is impacted by a storm. Otherwise winds remain mostly light and southerly. -BL
MARINE
Issued at 310 AM CDT Wed Apr 23 2025
Aside from the potential for thunderstorms over the protected waters during the next 36 hours or so, favorable conditions for maritime operations are expected. Onshore flow is likely to continue through the period with wind speeds for the most part remaining near 10 knots or less.
