New SHORT TERM, LONG TERM, AVIATION, MARINE

SHORT TERM
(This evening through Thursday night)
Issued at 254 PM CDT Tue Apr 22 2025

A somewhat difluent upper level pattern defined by prevailing west-southwesterly flow in the mid and upper levels will remain in place through Thursday night. Embedded within this flow, a weak upper level vorticity maxima will pass through the region tomorrow. A secondary and even weaker vorticity max will slide through on Thursday. These weak forcing mechanisms aloft will interact with a warm and unstable airmass to induce scattered convective activity once again tomorrow and Thursday. The convection will be diurnal in nature with peak activity occurring in the late morning and afternoon hours as temperatures climb into the lower 80s. Although most of the convection will remain weak due to a lack of decent shear and marginal mid-level lapse rates, a few of the storms could develop deep enough updrafts to produce some small hail and gusty winds during the afternoon hours. The bigger concern will continue to be the combination of slow storm motion and above average atmospheric moisture content. Locally high rainfall rates of up to 2 inches per hour could produce some isolated flooding issues, depending on where the rain occurs.
Overall, an overall early Summer like weather regime will continue to dominate through the short term period.

LONG TERM
(Friday through Monday night)
Issued at 254 PM CDT Tue Apr 22 2025

Conditions will begin to shift on Friday as one final embedded weak vorticity maxima passes through the region in advance of a building ridge axis over the southern Plains. Diurnal convection will once again form, but increasing negative vorticity advection ahead of the approaching ridge will increase the mid-level capping inversion will keep the coverage more isolated to widely scattered Friday afternoon. With less cloud development a bit more subsidence in place, temperatures will further warm with highs in the mid 80s expected.

Further warming will take place this weekend into early next week as the deep layer ridge axis becomes firmly entrenched across the central Gulf coast. Strong deep layer subsidence will not only restrict most cloud development, but also allow temperatures to climb a good 10 degrees above average in the upper 80s and lower 90s on Saturday, Sunday, and Monday. Persistent onshore flow through the period will keep dewpoints elevated and conditions very muggy. These higher dewpoints will support heat index values in the low to even mid 90s over a large portion of the forecast area. Only the coastal zones will see more moderate temperatures as a seabreeze forms each day. The onshore flow will also limit overnight cooling as lows only dip into the upper 60s and lower 70s, and have opted to use the NBM 75th percentile output for each night in the extended period. Given that this heat is coming on very early in the season, everyone needs to ensure they remain hydrated and to seek shade if they are participating in outdoor events.

AVIATION
(18Z TAFS)
Issued at 254 PM CDT Tue Apr 22 2025

Convective activity is currently more suppressed at this time than it was yesterday with the only convective cells currently near MSY. Have VCTS wording to reflect the risk of nearby thunderstorm activity at MSY through 19z. Otherwise, probabilities of convection are too low to mention in the forecast through the afternoon and early evening hours at the remainder of the terminals. If a storm develops near a terminal, a short term update will be made. Tonight, another round of low stratus and fog will develop as a inversion strengthens. This will lead to a period of IFR conditions at all of the terminals, generally between 08z and 14z. After 14z, increasing boundary layer mixing will allow the fog to clear and ceilings to lift into MVFR range.

MARINE
Issued at 254 PM CDT Tue Apr 22 2025

A very Summer like stretch of largely benign weather conditions will be in place across the coastal waters through the weekend and into early next week. A persistent high pressure system parked over the eastern Gulf will keep southeast flow of around 10 knots in place. This will result in seas of 2 to 4 feet through the period. No significant concerns for maritime operations are anticipated.
