Synopsis for pascagoula to atchafalaya river out 60 nm -
winds continue to remain elevated early this morning as a cold front continues to move further offshore. Hazardous conditions will subside later this morning as surface ridge moves overhead. As that high pressure center slides east this week, onshore flow will return and remain in place until the next frontal system on Thursday.

SHORT TERM
(Today through Wednesday)
Issued at 358 AM CDT Tue Mar 19 2024
The axis of the upper level trough that brought the most recent cold front through the region is now east of the Appalachian Mountains and headed to the Atlantic Ocean. Surface high following this system is currently near the Aklatex and will continue south to the northern Gulf Coast this evening. This will lend to a cool but pretty spectacular day. Guidance spread for highs today is relatively small, thus stuck with deterministic NBM. Moving into the overnight period, surface high will be right along the AL and FL panhandles. This, along with strong radiational cooling from light winds and clear skies, would lead to cooler temps. However, upper level ridge will already be moving in from the west which should counter cooling enough to result in lows slightly warmer than they are this morning. Slight amplification of the of that ridge on Wednesday will bring temps back to climatological normals.
MEFFER
LONG TERM
(Wednesday night through Monday)
Issued at 358 AM CDT Tue Mar 19 2024
A cutoff upper low currently centered over Southern California will begin tracking east as deep trough now over the eastern US moves offshore. Model evolution of this feature suggests that the closed low will open up into more of a shortwave trough as it tracks east across the southern tier of the country. Operational global models are quite close in timing and placement of this system, with it tracking across the Lower Mississippi Valley on Friday. As showers and thunderstorms develop along the appendant cold front, will have to monitor for severe weather. Model soundings suggest a strong warm nose for the northern 2/3rd of the CWA will keep any storms from being surface based. Elevated instability and very low wbz values (8- 10kft) could support hail. Shear dropping off while instability increases isn't a conduce setup. The only area in the CWA where there may be any real chance for severe storms appears to be right along the LA coastline where surface temps could be warm enough to aide storms in being surface based.
Benign weather returns this weekend as the shortwave shifts east and zonal flow develops aloft. Near to above normal temps with no rain in the forecast for that period.
MEFFER
AVIATION
(06Z TAFS)
Issued at 358 AM CDT Tue Mar 19 2024
VFR conditions will prevail throughout the TAF period. Such dry airmass in place will limit cloud cover to just minimal cirrus seen from time to time. Wind field will break down today as surface ridge to the north settles in aloft. Thus, expect mostly light and variable with little if any flight concerns through the cycle.
MEFFER
MARINE
Issued at 358 AM CDT Tue Mar 19 2024
Most recent cold front that moved through is now well south of the local area, almost down to the Yucatan Peninsula. Surface ridge behind that boundary is currently centered near the Arklatex will continue southward today, reaching the northern Gulf Coast later this evening. As it does so, the local pressure gradient will drastically weaken which will diminish ongoing elevated winds. Thus, will carry on current short-term marine hazards in place, both of which fall off before noon today.
The nearby surface high will slide east over the next few days which will bring the return of onshore winds. Expect them to remain there for the majority of the week. Should begin to see a gradual increase in winds/seas in the latter half of the week as a shortwave tracks across the southeastern US. Low-end small craft conditions will be possibly leading up to and after this system passes as the pressure gradient supports those wind conditions.
