Synopsis for pascagoula to atchafalaya river out 60 nm -
southerly return flow will persist over the area through the week with high pressure anchored to our east. The pressure gradient between this high and a storm system over the great plains will tighten a bit on Tuesday, resulting in an increase in winds and seas, before relaxing again on Wednesday.

New MARINE

SHORT TERM
(Today through Tuesday)
Issued at 245 AM CDT Mon Apr 15 2024

Early morning upper air pattern showed upper ridging from south Texas to the Dakotas, with an upper low centered near Las Vegas.
At the surface, high pressure extended from near Bermuda westward across much of the northern Gulf of Mexico. A stationary frontal boundary was well to the north of the area near Interstate 70.
Other than a little bit of cirrus, skies were mostly clear across the local area at 2 AM CDT with temperatures ranging from the mid 50s to mid 60s. A few minor reductions in visibilities were noted near the Mississippi River, but no indications of dense fog at this time.

The axis of the upper ridge will shift to the east of the area on Tuesday, as the upper low near Las Vegas lifts northeastward to near Omaha by Tuesday evening. Southerly flow will strengthen a bit, especially on Tuesday, but precipitable water values don't really look to increase significantly. Other than somewhat of an increase in cloud cover, especially for a few hours around sunrise Tuesday, any sensible weather impacts should be limited. NBM deterministic numbers for highs are generally near or above global deterministic numbers, but yesterday's highs indicate NBM values are reasonable. Forecast dew points overnight should be a reasonable solution.

LONG TERM
(Tuesday night through Sunday)
Issued at 245 AM CDT Mon Apr 15 2024

With the upper low lifting into the Great Lakes Wednesday into Thursday, the upper ridge rebuilds along the Gulf Coast, with the surface boundary remaining well north of the area. Can't rule out a stray shower or storm over southwest Mississippi by Thursday afternoon entirely, but GFS PoPs look to be a bit too high and like the NBM PoPs better. For the weekend, ridging gets suppressed a bit southward. Both the GFS and ECMWF operational runs move several shortwaves through zonal flow across the southern states Friday through the weekend. The strongest of the shortwaves looks to be on Sunday, with the ECMWF about 6 hours quicker than the GFS. For now, will ride with the NBM solution, with chance PoPs, mainly Saturday afternoon through Sunday. NBM high temperatures running above both the global operational numbers Thursday/Friday, and likely to be a degree or two too warm, as 90 degree temperatures in April are a rare event, even in southeast Louisiana. Baton Rouge has only exceeded 90 degrees in April 3 times in the last 25 years, and two of those were back to back in 2006.

AVIATION
(12Z TAFS)
Issued at 624 AM CDT Mon Apr 15 2024

Most terminals VFR this morning. The main exception has been KMCB, which has been primarily at IFR or lower for the past 3 hours, occasionally at or below field minima. KHDC was briefly experiencing low conditions but improved shortly before issuance time. Expect KMCB to improve by about 14z. Little in the way of clouds expected for the daytime hours today, but likely to see cirrus level clouds increase toward sunset. With low level moisture expected to continue to increase overnight tonight, most terminals expected to see MVFR to IFR ceilings to develop beyond 06z Tuesday, probably closer to 10z. Those ceilings would be expected to improve by mid-morning Tuesday. Southeasterly winds will start to become more prevalent this afternoon with most terminals near or above 10 knots, with somewhat stronger winds anticipated during the daytime hours Tuesday.

MARINE
Issued at 958 AM CDT Mon Apr 15 2024

Overall, expect marine conditions to be quiet, with the only area of concern at this time being a likelihood for Small Craft Exercise Caution headlines on Tuesday and Tuesday evening when the pressure gradient will be a bit tighter than surrounding periods.
The next period of stronger winds beyond that appears to be late in the weekend or early next week as a frontal boundary works into the area. But that is beyond the scope of the current marine forecast package.
