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 Wednesday. Winds will briefly increase to 15 to 20 knots ahead of an approaching cold front Wednesday night into Thursday. After the front moves through, winds will shift to the north and northeast and decrease in speed to 10 to 15 knots on Friday and Saturday. Seas will generally be between 1 and 3 feet over the period, but will briefly increase to 3 to 5 feet on Thursday.

NEW SHORT TERM, LONG TERM, MARINE
SHORT TERM
(Today through Wednesday Night)
Issued at 307 AM CDT Tue May 7 2024
Low stratus is still a "thing" if you will this morning as very rich low level moisture continues to stream northward from the Gulf. In fact, last hour the dew point had increased to around 74F here at ASD, so naturally low stratus isn't far behind, especially this time of year with such a rich boundary layer in place. The low stratus deck will begin to lift the moment insolation occurs later today.
A somewhat weak H5 ridge across the Bay of Campeche and southern Gulf will help warm most of our region well into the 80s again today and wouldn't be surprised if several locations such as BTR metro reach 90 degrees. The cooler spots will be along the Mississippi Gulf Coast where onshore flow will help moderate these areas just a bit right along the immediate coastline as SSTs are still a tad on the low side (enjoy that Mississippi folks while you can). Otherwise the pattern will evolve to a more active southwesterly flow aloft. That said, any shortwave or impulse within this flow looks to stay to our north and a cold frontal boundary begins to hang up within the mean flow across the ArkLaTex and points northeast toward the Cumberland Plateau and lower Sequatchie Valley of east Tennessee. As heights and thicknesses continue to rise through the end of the short term period, expect temperatures to respond with much of the area again reaching at the very least 90 degrees (again outside of the immediate coast). (Frye)
LONG TERM
(Thursday through Monday)
Issued at 307 AM CDT Tue May 7 2024
Long term picks up where the short term drops in terms of. Again, heights and thicknesses will continue to slightly increase on Thursday, which should be our warmest/hottest day as high temps rocket into the lower to middle 90s for most of the region. This along with plenty of low level moisture around could cause heat index values to rise close to or in excess of 100F on Thursday.
During the overnight Thursday and into Friday night an amplifying Canadian trough over the eastern half of the US will begin to move a surface cold front toward our region. The front looks to clear the region from NW to SE Friday morning or early Afternoon. We'll need to watch for some severe potential with this given the moderate instability. Although wind shear will be a bit on the lackluster side, cannot rule out at least some severe weather potential. Also, keep in mind that depending on the orientation of any prior QLCS, cold pool dynamics may also force the front through a tad earlier, which could limit the overall window for severe weather albeit not a limiting factor overall for severe weather.
CAA will occur, although CAA will likely be offset by sun angle and insolation given the calendar. However, temps in the upper 70s or lower 80s is much better, which should make for an AMAZING weekend ahead. The area should remain under mostly dry northwest flow, at least briefly. Going into the start of the new workweek next week things get a bit tricky in terms of global solutions.
The front that passes through the region on Friday stalls to our south...well to our south. However, globals show a more robust upper level impulse dig over the Texas Hill Country and eventually help develop showers and storms along the front as it gradually lifts back northward ahead of this feature. The question is how far north does the front lift ahead of this impulse? And will isentropic upglide be enough to keep some mention of POPs to start the workweek? With this package yet again, the medium range is a bit on the low confidence side for now given model differences with some being fairly large. (Frye)
AVIATION
(06Z TAFS)
Issued at 1132 PM CDT Mon May 6 2024
VFR conditions will be found at all of the terminals through the next few to several hours. In the morning, generally between 08z and 14z, some boundary layer decoupling will occur as temperatures cool and winds decrease. Another round of IFR and MVFR stratus development is expected with the most prevalent IFR conditions expected at MCB where decoupling will be greatest. The remainder of the terminals should see ceilings of 1000 to 1500 feet in the early morning hours. After 15z, increased thermal mixing of the boundary layer will allow the stratus deck to begin breaking and lifting into VFR range. (ME)
MARINE
Issued at 307 AM CDT Tue May 7 2024
Locally moderate winds will continue across the MS Sound and tidal lakes through today. This will allow the continuation of cautionary headlines. Eventually, winds gradually get a bit stronger, which may require SCA headlines late Wednesday and into the day on Thursday as the low level flow increases ahead of an approaching cold frontal boundary. Behind the frontal passage early Friday, expect winds to shift to an offshore flow. Remaining moderate, there could be a need for Cautionary Headlines or lower-end SCA before winds improve going further into the weekend. (Frye)
