SHORT TERM
(Tonight through Thursday night)
Issued at 307 PM CDT Tue May 7 2024
Another very warm and muggy day with air temperatures in the mid 80s and dew points in the mid 70s. A few very small brief showers have popped up every now and then with maybe 0.01 of rainfall at best.
Similar conditions will continue for Wednesday into the day on Thursday, so A/C units will be getting plenty of work.
Forecast becomes a little more interesting for late Thursday into Thursday night. The upper level ridge over the forecast area will flatten out and this will allow a short wave to push a surface "cold" front into the forecast area during the evening hours and through it during the overnight. Still some question as to how far south the upper level energy and low convergence will match up to allow for showers and thunderstorms to develop and this will be reflected in the pop forecast with high numbers over central Louisiana and lower numbers along and south of I-10.
A highly anomalous Gulf air mass will be in place before the front arrives with PWAT values in the 1.75 to 2 inch range which are over the 90th percentile of SPC daily climo. Also, favorable speed shear, low level instability, and favorable mid level lapse rates, would allow for strong to low severe storms producing heavy rainfall. The question is just how much convection can get going.
Therefore, the severe weather and excessive rainfall potential will be on the low end. Still a couple of days away to watch this and fine tune the details.

LONG TERM
(Friday through next Monday)
Issued at 307 PM CDT Tue May 7 2024
Longterm period starts off fairly dry behind a passing cool front and under increasing heights aloft. The ridging that does build in Friday and Saturday will be weak, but combined with slightly drier airmass, no rain chances are anticipated on these days.
Surface high pressure ridge moves to the east on Sunday allowing for return flow and meager rain chances during the afternoon in western zones. Best chance for showers and thunderstorms occurs on Monday and again Tuesday with the arrival of a series of shortwave trofs over the region. Broad lift ahead of trofing will lift a warm front into coastal areas Monday; widespread convection is expected throughout the remainder of the day. Fcst CAPE profiles look very meager on globals, pointing to warm cloud layer processes and very efficient rainfall under forcing from the trof (fcst PWATs well above 1.75 inches once again). So long as precipitation remains progressive and we get a downpour that moves along quickly, flooding concerns will be lower than previous weeks. All concerned parties should monitor the forecast for any changes in the coming days.
Rain chances pick up oncemore on Tuesday with another weak shortwave pulse moving over the coastal warm front.
Thanks to rain-cooled airmass and ambient cloud cover, temperatures will be held in check through the longterm. High temps in the lower 80s are on tap.

AVIATION
(00Z TAFS)
Issued at 610 PM CDT Tue May 7 2024
Borderline VFR/MVFR ceilings will again decrease to MVFR/IFR by 02Z as a cloud deck moves inland. A very moist airmass will keep clouds in the forecast for the rest of the TAF period. Winds will remain southerly and elevated tonight with max winds speeds around 10 knots. Winds will become gusty tomorrow morning and will remain from the south.
MARINE
Issued at 307 PM CDT Tue May 7 2024
High pressure at the surface off the southeast US coast will ridge into the coastal waters over the next couple of days, and this will allow light to moderate onshore flow with mainly low to modest seas to continue.
Late Thursday, a surface front will move through the coastal waters with a few showers or storms. A moderate offshore flow will then develop behind the front for Friday into the weekend.
