Synopsis for pascagoula to atchafalaya river out 60 nm -
high pressure centered off to our east-northeast will provide persistent southeast flow of around 10 to 15 knots through Thursday. A frontal passage Thursday night into Friday will lead to stronger offshore winds of 15 to 20 knots with at least widespread cautionary headlines, if not small craft advisories.

Area Forecast Discussion...UPDATED National Weather Service New Orleans LA 638 AM CDT Mon May 6 2024

NEW AVIATION

SHORT TERM
(Today through Tuesday)
Issued at 330 AM CDT Mon May 6 2024

A rather zonal/progressive upper level flow will continue through the morning and into the afternoon hours across our region. With low level moisture continuing to increase with a southerly return flow, some low stratus/fog will be possible, especially across southwest MS and the Florida parishes of Louisiana. This should lift shortly after sunrise as stronger insolation takes place allowing clouds to mix out effectively. Later today and into tonight an H5 impulse begins to round the base of the larger scale trough centered over the plains and Rockies. Overall, this feature appears weak in nature, but could spark off an isolated shower or storm or two. At this juncture, with much of the support being to our northwest, only our northwestern tier will have the better POPs...even then generally at or below 30 percent.

Overnight any rainfall that does develop will come to an end with the loss of daytime heating as well as the upper level impulse racing downstream. Tuesday, the region will transition to a more active southwesterly flow with an impulse or two expected to move northeast through the flow providing folks generally along and north of the I10/12 corridor with nonzero POPs. (Frye)

LONG TERM
(Tuesday night through Sunday)
Issued at 330 AM CDT Mon May 6 2024

Going into the long range, not much change to the overall pattern across our region early on. Heights will slightly increase with a 592dam ridge across the southern Gulf of Mexico with gradually rising heights over our region. Our area will remain under the active southwesterly flow, but any impulse appears very subtle at this juncture with very little in terms of POP/QPF signal at least through midweek. The broad scale trough across the northern Plains through the Rockies will continue to amplify with time.
This will help a frontal boundary move a bit closer or into our region Thursday and Friday. With at least some better upper support late Thursday and into Friday, think that this will likely be the best rain chances we have this week, at least in terms of coverage and QPF.

Going into the upcoming weekend things get a bit interesting. A bit of a cool down opposite the front is expected. The front actually looks to move through the region and as far south as South Florida (which is incredibly rare for this time of year).
The front is being driven by a Canadian upper trough that amplifies over the Great Lakes and into the Ohio River Valley late this week and into the weekend. With a bit of a pattern change back to dry WNW or zonal upper flow, the weekend should actually be cooler and drier after reaching the lower and middle 90s on Wednesday and Thursday. Beyond this time the forecast becomes very tricky. The GFS has another Canadian trough amplifying over the plains and into the mid MS River Valley. At the same time, this trough begins to phase with a pacific trough finally kicking east from the Rockies. This would provide a source for a bit of an active weather pattern later this weekend and into early next including well below average temperatures for this time of year.
The ECM has a bit different look with a short wave ridge across the MS River Valley on Monday. So needless to say overall confidence beyond Saturday drops pretty quickly. In fact, there's roughly a 20 degree difference between the GFS and ECM in terms of temps on day seven. For now, we will lean more toward climo, which would favor more of an ECM solution, but not totally sold on tossing the GFS solution out the window as of now, as the ECM still shows the aforementioned Canadian trough...just avoids phasing with the ongoing Pacific trough over the western tier.

AVIATION
(12Z TAFS)
Issued at 637 AM CDT Mon May 6 2024

Any CIG/VIS reduction this morning will likely give way to VFR conditions through today and into this evening. There could be another low stratus/patchy fog event overnight, especially the south MS terminals. Otherwise light to moderate southerly winds are expected with perhaps a couple of higher gusts during the afternoon hours. (Frye)

MARINE
Issued at 330 AM CDT Mon May 6 2024

Moderate onshore flow will continue through mid to late week this week. Winds across the MS Sound and the tidal lakes may enhance some during the daytime. Used cautionary headlines respectively.
Otherwise, winds begin to increase later on this week with SCA may be needed going into the late week and into te upcoming weekend. (Frye)
