Synopsis for pascagoula to atchafalaya river out 60 nm -
high pressure centered off to our east-northeast will provide persistent southeast flow of around 10 to 15 knots through the rest of today with some locally higher gusts, strengthening to 15 to 25 knots tonight into Thursday ahead of an approaching cold front. The front will pass through the coastal waters Thursday night or early Friday. Winds will shift to the north and ease to 10 to 15 Friday and Saturday. Seas will generally be between 1 and 3 feet over the period, but will briefly increase to 3 to 6 feet on Thursday. By Sunday, another area of low pressure will begin to approach the area and winds will turn easterly and then southerly ahead of this low.

SHORT TERM
(This evening through Thursday night)
Issued at 321 PM CDT Wed May 8 2024
The forecast for the rest of today looks to be on track with high temperatures sitting right around their peak for the day, in the upper 80s to lower 90s. Temperatures for tomorrow will be even warmer ahead of a cold front that will be approaching. NBM deterministic was running a touch warmer than MOS data and guidance, so ran the 50th percentile for MaxT's. This brings afternoon highs for tomorrow into the low to mid 90s for most of the CWA Heading into Friday, bumped temperatures up a bit as the NBM seems to be banking on clouds sticking around longer than they look to. Still about a 5 degree "cooldown" from Thursday with temps in the mid to upper 80s.
Now onto the main story of the short term period, tomorrow chance of severe weather. The northern half of our CWA is highlighted in a SLIGHT Risk by SPC for mainly wind and hail. Currently there is quite a bit of model discrepancies. Many of them show an MCS forming somewhere back in TX and they diverge from there. Most have this MCS staying to our north, however as we have seen with past events until this system actually forms it can have a more north bias. So the 00z CAMs tonight and the 12z CAMs tomorrow morning will be very telling. For now didn't adjust PoPs a ton, with them peaking in the early morning hours Friday. Taking a look at model soundings, one thing that will not be an issue is CAPE with ~3000-3500J/Kg available. There isn't much in the way of directional shear, but decent speed shear, so tornadoes are less of an issue for our area. 500mb temps are around -10C which isn't crazy but is plenty cold for us to have some large hail.
LONG TERM
(Friday through Tuesday night)

Long Term...
Saturday through mid-week... Saturday and most of Sunday, zonal flow will dominate the upper level pattern. Northerly surface winds during this time will help to suppress humidities and keep instability down, which will reduce PoPs. So, not much rain expected Saturday into Sunday morning. Temperatures will be fairly nice over the weekend with highs in the low to mid 80s Saturday and upper 70s to low 80s Sunday with lows in the low 60s.
An upper level impulse moves through the area Sunday night into Monday morning with multiple small upper level impulses in close succession through the early part of next week. For the impulse moving into the area Sunday into Monday, southerly surface winds will help advect moisture and instability ahead of the system. The bulk of the best moisture and forcing looks to be for our northernmost areas, but that could definitely shift as things develop over the next few days. This is where there is some model uncertainty over the location of the highest rainfall/strong weather. This will hopefully become more clear in the coming days.
As stated above, more upper level impulses will be influencing the area after Monday through the workweek. There is still a lot of model variability and uncertainty surrounding the strength of these troughs and timing. But it is becoming increasingly likely that we will see multiple rounds of rainfall Monday through Thursday of next week with near normal temperatures. More details will become a little more defined as we get toward the beginning of next week. MSW

(00Z TAFS)
Issued at 625 PM CDT Wed May 8 2024
Cumulus field has bounced between VFR and MVFR late this afternoon. MVFR conditions are expected to become widespread this evening as southerly flow continues. At this time, expect ceilings to remain above FL010 with the possible exception of KMCB, which could fall into the IFR range around FL008 for several hours around sunrise. MVFR ceilings are likely to continue through at least the morning hours on Thursday, but some may improve to VFR during the afternoon hours. Any significant threat of TSRA on Thursday, if it occurs at all, would be beyond 00z Friday, with KMCB being most favored.
