Synopsis for pascagoula to atchafalaya river out 60 nm -
surface high pressure centered northeast of the local area will slowly shift from the carolinas to the western atlantic from now to early next week. This will keep onshore flow in place with a gradual shift in wind direction from southeast to south. The pressure gradient will generally support wind speeds around 10 knots with occasional periods of speeds closer to 15 knots.

SHORT TERM
(This evening through Wednesday night)
Issued at 309 PM CDT Tue May 21 2024

An upper level ridge is currently centered over central Mexico just southwest of Brownsville Texas. The axis of this high currently extends northeastward across the southeastern US to the Ohio River Valley. It will suppress southward the next couple days as an upper level trough currently moving through the Northern/Central Plains tracks northeastward across the northern Mississippi River Valley.
More locally, not much change expected to 500mb heights which means slightly above normal temperatures persist. In addition, this will keep rain chances out of the forecast. Otherwise, thats about it.

MEFFER

LONG TERM
(Thursday through Monday night)
Issued at 309 PM CDT Tue May 21 2024

Like the near-term, really not much to talk about in the extended portion of the forecast. High pressure will maintain hot and rainless conditions. Temperatures will creep up a few degrees the rest of the forecast period as the upper ridge nearby strengthens. A few locations could approach record highs this weekend. At the moment, it doesn't appear that dewpoints will be high enough to support heat indicies anywhere near heat advisory, but should at least exceed 100 late this week.

The ridge will continue to be suppressed southward as another trough tracks across the mid Mississippi River Valley this weekend. That'll eventually allow for some afternoon convection but currently doesn't look like that'll happen until sometime next week.

MEFFER

AVIATION
(18Z TAFS)
Issued at 309 PM CDT Tue May 21 2024

A scattered CU field that developed this morning encompasses most of the local area. Observations at terminals indicate VFR conditions are in place now that CU decks have risen. Expect VFR to dominate the rest of the day and evening hours. MVFR will be possible at some TAF sites late tonight into Tuesday morning as low clouds potentially develop. Southerly flow will continue with light/variable winds in the overnight period.

MARINE
Issued at 309 PM CDT Tue May 21 2024

Surface high pressure centered northeast of the local area will slowly shift from the Carolinas to the western Atlantic from now to early next week. This will keep onshore flow in place with a gradual shift in wind direction from southeast to south. The pressure gradient will generally support wind speeds around 10 knots with occasional periods of speeds closer to 15 knots.
