New SHORT TERM, LONG TERM, AVIATION, MARINE

SHORT TERM
(This evening through Saturday night)
Issued at 314 PM CDT Thu Apr 24 2025

Another weak upper level shortwave trough will move through the Lower Mississippi Valley late tonight into tomorrow, and this feature should provide just enough forcing to allow for another round of shower and thunderstorm activity tomorrow. Initially, a weakening MCS will be moving into the northern portion of the CWA tomorrow morning. This weakening system will produce an outflow boundary that should serve as a focusing mechanism for additional convective activity along the I-12 corridor, especially for areas around Baton Rouge and Hammond. PWATS will be slightly lower tomorrow, but will still be in the 75th percentile range. This will support a continued heavy rainfall threat has storm motion remains low tomorrow. The highest PoP values will be along and north of the 10/12 corridor tomorrow afternoon. The convective activity should start to wane very quickly in the evening hours as the shortwave trough departs to the east and increasing heights aloft associated with a building ridge axis start to influence the region.

As the ridge continues to build into the region over the weekend, increasing deep layer subsidence will warm and dry out the atmosphere substantially. PWATS will fall to around the 25th percentile for this time of year and this will greatly inhibit cloud development overall rain chances. At most, an isolated shower or storm may develop over parts of southwest Mississippi as another weak shortwave passes through the mid-Mississippi Valley allowing for just enough lift to overcome the strong capping inversion. Otherwise, mostly sunny skies and warmer temperatures are anticipated for Saturday. Highs will easily climb into the mid to upper 80s and heat index values will rise into the lower 90s. Overnight lows will only cool into the upper 60s and lower 70s as persistent low level onshore flow keeps pumping Gulf moisture into the region.

LONG TERM
(Sunday through Wednesday night)
Issued at 314 PM CDT Thu Apr 24 2025

Sunday through Tuesday will be very warm and dry as the deep layer ridge axis remains firmly entrenched across the central Gulf coast. PWATS will remain in the 25th percentile range and temperatures will easily climb into the upper 80s over much of the area. Dewpoints will also remain elevated in the lower 70s and this will support heat index values in the low to mid 90s. The warmest readings will be over inland areas and away from the moderating seabreeze. Overall, conditions will feel more akin to those seen in late May or early June as opposed to late April.

A pattern change in the upper levels will take hold on Wednesday as the ridge axis begins to shift to the east and a vigorous southern stream trough moves into Texas. Although ridging will begin to decrease and PWATS will climb back to the median for this time of year, a strong mid-level capping inversion will remain in place. This is due to continued influence from the departing ridge keeping dry air in place in the mid-levels. At most, isolated and diurnally forced convection could develop over the far northwest part of the forecast area where slightly lower heights and a weaker capping inversion are expected to be in place. Otherwise, warm and dry conditions will persist as highs climb back into the mid to upper 80s and heat indices rise back into the lower 90s.

AVIATION
(18Z TAFS)
Issued at 314 PM CDT Thu Apr 24 2025

Scattered convective activity will be the primary concern through 00z, but the risk of convective impacts is too low to include at most of the terminals. BTR is the outlier as a line of showers and weak thunderstorms is in close proximity to the airport currently.
This line of convection will gradually move further east of the airport and have VCTS wording ending at 19z. Otherwise, a mix of MVFR and VFR ceilings ranging from 1500 to 3500 feet will be in place at the terminals. Tonight, a weak inversion will allow for some fog and low stratus to form over the more inland terminals with IFR conditions forecast for BTR and MCB between 10z and 14z.
MVFR ceilings will be in place at the remainder of the terminals as boundary layer conditions remains more mixed closer to the coast. After 14z, rapid improvement in conditions is expected as the inversion breaks amid warming surface temperatures.

MARINE
Issued at 314 PM CDT Thu Apr 24 2025

No significant impacts to maritime activities are expected through early next week. High pressure will be centered directly over or just to the east of the waters through the period, and this will result in light winds of around 10 knots and seas of 1 to 3 feet on average.
