GMZ500 427 Am Cdt Thu Jun 20 2024

Synopsis for pascagoula to atchafalaya river out 60 nm -
winds will remain in the 20 to 30 knot range over much of the waters today, in response to the tropical system in the bay of campeche. Some gusts in excess of gale-force will be possible, primarily over the outer coastal waters west of the mouth of the mississippi river. Seas up to 14 feet continue to be expected in the offshore waters today. A gradual decrease in wind speeds and seas is expected later in the day on Thursday into Friday as the low in the bay of campeche moves into mexico and weakens.

New AVIATION

SHORT TERM
(Today through Friday)
Issued at 400 AM CDT Thu Jun 20 2024

Tropical Storm Alberto about to make landfall on the Mexican coastline early this morning, and expected to weaken rapidly and dissipate during the day today as it reaches higher terrain in Mexico. As the pressure gradient weakens, the wind field should relax somewhat. However, it will take time for the winds and swell to abate. Additionally, with no significant change in the wind direction, it will take some time for the higher water in the tidal lakes to drain. Current plan is to replace the Coastal Flood Warning with a Coastal Flood Advisory beyond today's high tide cycle for tomorrow's high tide cycle. It can be cancelled later if water levels fall quicker than forecast, but current guidance indicates there may be at least some minor issues on Friday.

Upper ridging over the Mid-Atlantic States will build southwestward over the next couple of days and be centered near Memphis Friday afternoon. Water vapor imagery already shows drier air moving westward through much of the local area. This was noticeable in the 00z LIX sounding which showed a precipitable water value of 1.6 inches, compared to the 2+ inches we'd seen for the previous couple of days. Northern portions of the area may already have precipitable water values nearer to 1 inch, if the BMX sounding was any indication. We'll continue to see drier air filter into the area, with precipitable water values closer to 1.2 inches by Friday afternoon. However, there may still be enough moisture both today and Friday to support at least a few showers or storms. We are even seeing that early this morning with a few echoes moving onshore from the Gulf. Most of that should be south of the Interstate 10 corridor both days, and rain amounts should be rather scarce. Have undercut the NBM PoPs somewhat, closer to the global numbers, as they've been overstating things for the last several packages.

With less precipitation, and likely less clouds, that argues for going on the high end of temperature guidance, and the NBM deterministic numbers support this. That should put pretty much every one in the lower-middle 90s both today and Friday.

LONG TERM
(Friday night through Wednesday)
Issued at 400 AM CDT Thu Jun 20 2024

Upper ridging will continue to build westward, and be centered near the New Mexico-Arizona border on Sunday, where it will take up residence for next week. For the weekend, and potentially through Monday, there will be a southeastward extension of the ridge into the northern Gulf of Mexico. Any convective development over the weekend should remain on the isolated side and be limited to primarily the afternoon hours from about Interstate 10 southward. As we move into early next week, the upper flow across the area becomes northwesterly, which opens up the potential for shortwaves moving through that flow to trigger clusters of thunderstorms. Of course, timing those shortwaves at this time range is going to be handled differently by the models. Can't see fighting the NBM PoPs for a target of opportunity beyond perhaps Monday. With precipitable water values well in excess of 2 inches for the middle of next week, certainly appears that storms could be efficient precipitation producers.

NBM deterministic temperatures are generally on the high end of the guidance envelope for highs this weekend and Monday, which appears reasonable, as long as convection doesn't develop too early in the afternoon. At mid week, things should trend a bit closer to normal, as the higher precipitable water values argue for an earlier start to convective development. Some potential for heat advisories for at least Sunday/Monday depending on timing of convective development, with heat index values approaching 110F.

AVIATION
(12Z TAFS)
Issued at 624 AM CDT Thu Jun 20 2024

Most terminals with VFR conditions ongoing, but there are occasional MVFR ceilings as isolated showers move through the southeasterly flow. Echo tops on the showers on KHDC radar were only near the freezing level, so no large threat of TSRA in the very near term. Will handle with VCSH to acknowledge there are some out there.

May see somewhat better coverage later this morning or early afternoon as heating gets involved. If there's any real threat of TSRA, it'd be at KHUM this afternoon, and VCTS is likely overstating things. But there is a weak shortwave moving through the easterlies, and moisture levels haven't fallen off enough to preclude it. With loss of heating toward sunset, most or all of the limited amount of convection should dissipate, with vFR conditions overnight tonight.

Easterly winds of 15 knots or greater may impact terminals south of Interstate 10...KGPT/KNEW/KMSY/KHUM from mid-morning until approximately 00z Friday.

MARINE
Issued at 400 AM CDT Thu Jun 20 2024

As Tropical Storm Alberto makes landfall and weakens/dissipates over Mexico, winds and seas should gradually subside today. Will replace the Small Craft Advisory over the tidal lakes with Exercise Caution headlines with forecast issuance. Will extend Small Craft Advisory over the western open waters through this evening, but allow it to expire on schedule at 21z elsewhere.
Can't rule out needing brief Caution headlines on the back end of the advisory this afternoon/evening, but will let the day shift folks reassess that.

Winds could remain around 15 knots for a good portion of Friday, but beyond that point, should be a much more benign period into early next week, outside of the potential for thunderstorms.
