SHORT TERM
(This evening through Tuesday night)
Issued at 310 PM CDT Sun May 5 2024
A shortwave ridge axis will remain over the area through Tuesday night, and this will help suppress most convective activity even as a series of weak shortwave features rides over the top of the ridge axis and through the Lower Mississippi Valley. At most, an isolated to widely scattered shower or storm could develop during peak heating hours tomorrow afternoon and again on Tuesday afternoon, and the most likely area for development will be across Southwest Mississippi and portions of Louisiana to the north of I-12. Any convection will remain weak and low-topped as a fairly strong capping inversion in the mid-levels remains in place. Any convection will quickly dissipate after sunset with dry conditions expected by the early evening hours both tonight, tomorrow night, and Tuesday night. The combination of lighter boundary layer flow and ample low level moisture will support some patchy fog and low stratus development each night. The fog and stratus will quickly clear by mid-morning as temperatures warm. Have stuck with NBM deterministic values for temperatures through Tuesday night with readings rising into the mid to upper 80s and lows dipping into the upper 60s and lower 70s.
LONG TERM
(Wednesday through Saturday night)
Issued at 310 PM CDT Sun May 5 2024
The deep layer shortwave ridge axis will continue to induce strong subsidence across the area on Wednesday. This will result in a very strong mid-level capping inversion, and have no mention of rain in the forecast for Wednesday afternoon. Temperatures will also warm beneath the highly subsident airmass with readings projected to climb into the upper 80s and lower 90s. A few locations could approach record high levels. Even warmer temperaturesare expected on Thursday as highs climb into the low to mid 90s over inland areas. These high temperatures will likely break records and those who are most vulnerable to heat should limit outdoor activities on Thursday. These warm values on Thursday are being driven by both ample subsidence aloft and some compressional heating ahead of an approaching cold front.
The cold front will move into the Thursday night, and some scattered convection will likely develop ahead of the front as it moves into a moist and unstable airmass in the low levels. Lapse rates will improve aloft as the influence of the ridge diminishes, and there could be a stronger storm or two as the front moves through. Otherwise, conditions do not look favorable for severe convection due to a lack of substantial shear. The front will clear the coast on Friday and a cooler and more stable high pressure system will advect into the area on Saturday.
Temperatures will fall back to more normal levels in the lower 80s on Friday, and could even cool to slightly below average by Saturday as the heart of the northern stream cold pool moves in.
AVIATION
(00Z TAFS)
Issued at 640 PM CDT Sun May 5 2024
All terminals VFR at forecast issuance time, although several are reporting a few clouds between FL020 and FL030. Later in the overnight period, MVFR to IFR ceilings will be possible at all terminals. Fog should be somewhat limited, with KMCB the most likely candidate. Any fog or low stratus should improve to at least MVFR ceilings by 14z or 15z, and VFR at midday. With the area expected to be in between shortwaves on Monday, any convective development is expected to remain isolated, and will not include in the forecast this far out. That's not to say the threat is zero, however. Southeast to south winds may near 15 knots during the afternoon tomorrow at most terminals.
MARINE
Issued at 310 PM CDT Sun May 5 2024
Through Wednesday, the region will remain on the western periphery of a broad surface high. This will keep prevailing southerly flow of 10 to 15 knots and seas of 1 to 3 feet in place. By Thursday, the approach of a cold front will result in a slightly tighter pressure gradient over the coastal waters, and this should push winds into exercise caution range of 15 to 20 knots. The front is expected to slip through the waters on Friday. Winds will shift to the north and remain elevated in exercise caution range.
