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 a broad area of low pressure 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 12 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 Thursday)
Issued at 353 AM CDT Wed Jun 19 2024

Strong upper ridging was centered over Pennsylvania early this morning, extending southwestward to Mississippi and Alabama.
Potential Tropical Cyclone One (PTC1) continued over the southwestern Gulf of Mexico and the Bay of Campeche. An upper trough extended from northwest Ontario to the Pacific Northwest.

The pressure gradient between the Bermuda high and the system in the southwest Gulf continues to produce breezy to windy conditions, mainly over the coastal waters early this morning.
Similar to yesterday, expect winds to pick up by mid-morning along the Mississippi coast and much of southeast Louisiana south of Interstate 10. It's a borderline case based on forecast wind speeds, but went ahead and issued a Wind Advisory from 16z to 00z today for that area. Winds should relax somewhat beyond sunset, and be a bit weaker on Thursday. Radar showing only very isolated echoes this morning, considerably less than the previous 2 mornings. This is likely due to somewhat drier air working into the area from the east. This was reflected in the 00z LIX upper air sounding, which had a precipitable water value of 1.89 inches, down from 2.06 inches on the Tuesday morning flight. Temperatures at 3 AM CDT ranged from the mid and upper 70s across the northern half of the area to the lower 80s in the New Orleans area.

The upper ridge to the northeast will gradually shift south and southwestward toward the area, and be centered over Kentucky by Thursday afternoon. This will gradually bring more dry air into the area, especially to the north of the Interstate 10/12 corridors, where forecast soundings have precipitable water values falling below 1.5 inches by Thursday afternoon, perhaps as low as an inch over southwest Mississippi. This should mean quite a bit less areal coverage of showers and storms compared to the last couple of days, probably later developing, and much less of a heavy rain threat.

With less precipitation expected and somewhat more sunshine today, we should see much of the area get to around 90 degrees, and possibly a couple degrees warmer tomorrow.

Will extend the Coastal Flood products for one more high tide cycle during the day on Thursday. The highest water levels are likely to occur during this afternoon's high tide cycle, but the probabilistic guidance indicates enough of a threat for issues to continue it Thursday.

LONG TERM
(Thursday night through Tuesday)
Issued at 353 AM CDT Wed Jun 19 2024

The upper ridge is forecast to continue to build southwestward and be centered near Memphis on Saturday, and then extend from New Mexico to the north central Gulf of Mexico by Monday. While we aren't likely to remain completely dry, we should get into more of a diurnally driven pattern where we get isolated to scattered areal coverage of showers and storms that develop during the mid and late afternoon hours. In other words, a more usual summertime pattern. This will also allow high temperatures to heat up a bit, with lower and middle 90s expected for much of the area. Humidity levels will be high enough that Heat Advisories may be necessary, perhaps as early as Saturday or Sunday, for portions of the area.

AVIATION
(12Z TAFS)
Issued at 623 AM CDT Wed Jun 19 2024

Most terminals currently VFR, but there will be occasional MVFR ceilings with bases near FL020-025 this morning. Radar showing isolated SHRA moving west-northwestward between KGPT and KASD at issuance time. Briefly brought visibilities down to 2SM at KGPT around 1045z, but improved quickly. Also produced a 28 knot gust during that SHRA.

Still will be the potential for SHRA/TSRA at most terminals today, with the possible exception of KMCB, but areal coverage is expected to be much less extensive than the past couple of days.
Any impacts will be brief, but IFR visibilities and MVFR ceilings will be possible. Will carry VCSH/VCTS as appropriate. Probably the more widespread concern will be for gusty easterly or southeasterly winds, likely in the 25-30 knot range, from the Interstate 10 corridor southward. This would include KGPT/KASD/KNEW/KMSY/KHUM. Perhaps a bit less wind at KHDC and KBTR, in the 20-25 knot range for peak gusts.

Expect any precipitation to dissipate near sunset if not sooner.
Wind speeds should also diminish to 10 to 15 knots or less toward sunset, with primarily VFR conditions expected overnight into Thursday morning.



MARINE
Issued at 353 AM CDT Wed Jun 19 2024

Will continue the Gale Warning and Small Craft Advisories as earlier issued. As PTC 1 moves inland over Mexico late tonight or Thursday, the pressure gradient should weaken and allow winds and seas to slowly subside Thursday into Friday. We may still need Small Craft Exercise Caution headlines for portions of the waters into Friday evening before the hazardous conditions relent entirely. As the winds slowly relax, the coastal flooding threat will as well, with water levels along the coast returning to more normal levels by Thursday night or Friday.
