Synopsis for pascagoula to atchafalaya river out 60 nm -
a stationary front will remain over the region through this evening before eventually moving southeastward as a cold front on late tonight and Saturday. Thundertorms along this boundary, especially overnight and Saturday morning will bring the threat of locally strong winds, large hail, and higher seas to the waters. Breezy southwesterly winds south of the front will subside and shift out of the northwest in wake of the cold frontal passage Saturday afternoon. High pressure builds in Sunday and remains over the waters through early next week.

UPDATE
Issued at 200 PM CDT Fri May 17 2024
Updated forecast through Saturday with a focus on timing of severe wx and heavy rainfall threat for the next event.
Convection has struggled to develop so far today (and we aren't complaining). A special 18Z RAOB sounding from KLIX shows a subsidence inversion near 850 mb in wake of last night's MCS that has helped to cap convection thus far. We are closely monitoring for convection to initiate along the quasi-stationary frontal boundary that is located just south of a line from Lafayette to Baton Rouge to Hattiesburg. This boundary has become increasingly better-defined as differential heating has magnified the temperature gradient (upper 60s/lower 70s on the cool side of the boundary and mid 80s in the warm sector). Low-level convergence has also strengthened near the front and this will provide a source of lift, but appears to be too shallow for convective updrafts to reach the LFC. Recent satellite trends show the CU field is building just south of the warm front along the Southshore, Coastal MS, and parts of coastal southeastern LA. This is the area where storms are most likely to initiate through mid afternoon. Expect coverage of storms to be widely scaterred given the absence of deeper forcing. However, any storms that to break the cap has the potential to quickly become severe with an EML overhead and strong instability rooted in the boundary layer. These storms will be capable of producing locally damaging winds (favorable wet microburst environment with high instability and mid-level dry air) and large hail (steep mid-level lapse rates).
SHORT TERM
(Today through Saturday)
Issued at 235 AM CDT Fri May 17 2024
Although there are a few storms remaining early this morning, any severe threat likely limited to borderline hail as main portion of shortwave is east of the area. Quite a bit of uncertainty regarding severe threat and heavy rain threat over the next 24 hours. Deepest moisture remains just offshore where dew points are in the mid and upper 70s, but drier air is over the northern portion of the area, where dew points are in the lower 60s. Next shortwave actually won't approach the area until the overnight period tonight into Saturday morning when precipitable water values will again approach 2 inches, as southerly surface winds pull moisture back into the area. Quite a bit of mid level dry air for much of the area until perhaps 06z Saturday, and would anticipate that instantaneous areal coverage during the day today should remain on the scattered side, with a significant increase in areal coverage during the mid to late evening hours. Drier air returns during the day Saturday.
Will keep the Flood Watch in place, as there was a fairly sizeable area of 1.5 to 3 inch rainfalls, and another inch or two on top of that overnight tonight could cause runoff issues.
Will not move off the NBM temperature forecast at this time, but the main question for high temperatures today will be cloud cover.
LONG TERM
(Saturday night through Thursday)
Issued at 235 AM CDT Fri May 17 2024
Upper ridging builds from Mexico into the Lower Mississippi River Valley beginning Saturday evening through much or all of the workweek. At present, it appears that any significant chance of precipitation beyond tomorrow morning is likely to wait until beyond the end of the forecast package, with at least some potential to remain dry through next weekend. Temperatures are expected to remain above normal through the forecast period.
AVIATION
(18Z TAFS)
Issued at 108 PM CDT Fri May 17 2024
A stationary boundary was drapped across the region this afternoon. Low clouds and fog has been socked in north of the boundary at KBTR and KMCB. Expected IFR conditions to continue through most of the afternoon although eventual improvement to MVFR should occur late in the day (between 21Z and 00Z). South of the boundary, CIGs are higher but a CU field has developed and kept the other TAF sites in MVFR CIGs . Expect bases to gradually increase through the rest of the afternoon and eventually VFR CIGs will become increasingly common south of the front. Coverage of showers and storms will be too isolated to mention in 18Z TAFs before about 02Z this evening. Showers and storms will become better organized late this evening and especially overnight as a disturbance approaches. This activity will be focused along the front which will progress slowly southward through the area.
Confidence in heavy rain and an extended period of IFR/LIFR conditions increases farther south. This is reflected in the 18Z TAFs with the greatest restrictions and longest period of TSRA mentioned for HUM, MSY, NEW, and GPT.
MARINE
Issued at 108 PM CDT Fri May 17 2024
The strongest winds thus far today has been present across the far southeastern coastal waters, but even here observations marginally support a SCA with occasional gusts to 20 kt. Winds have actually become light over the lakes where the pressure gradient is light near a stationary boundary.
Isolated thunderstorms are expected to develop near the coast late this afternoon and early evening. Although coverage will be limited, any of these storms have the potential to produce locally strong winds in excess of 34 kt, large hail, heavy downpours, lightning, and higher seas. The risk of hazardous conditions on the waters will increase overnight and continue through Saturday morning as storms organize along the front and move southward. Some of our model guidance is showing the potential for intense convective wind gusts in excess of 50 kt, perhaps locally to hurricane strength.
