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 the tropical system 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 14 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.

Area Forecast Discussion...UPDATED National Weather Service New Orleans LA 1121 PM CDT Wed Jun 19 2024

NEW AVIATION

UPDATE
Issued at 949 PM CDT Wed Jun 19 2024

Most of the isolated to scattered showers and storms have dissipated across the region this evening. Still may see additional isolated convection offshore with the diurnal cycle late tonight. The wind advisory was allowed to expire earlier as pressure gradient is finally starting to relax just a bit across the land based zones. Did keep the Gales for the 20-60nm Gulf waters as winds are still reaching those thresholds well offshore.
Otherwise, no other changes to the headlines or forecast with this midpoint update. (Frye)

SHORT TERM
(This evening through Friday night)
Issued at 402 PM CDT Wed Jun 19 2024

Current radar shows scattered showers across the CWA These showers are moving relatively quickly at around 25kts towards the west due to strong onshore flow north of Tropical Storm Alberto. Will continue to see easterly moisture advection combined with daytime heating to promote shallow convection through the rest of this afternoon. Although showers will be brief, rainfall rates will be fairly impressive with such a moisture rich column in place. In addition, don't be surprised to experience gusty winds 30-40 mph and precip loading transfers stronger winds aloft down to the surface. Loss of daytime heating will be the end of inland convection with coastal showers expected overnight.

0A strengthening upper ridge, possibly reaching 600dm (that's really really high), centered over the Appalachian Mountains will spread farther westward through the southeastern CONUS into tomorrow. This will cause Alberto to track west into northern Mexico, therefore removing some moisture content in our CWA The other aspect of this is subsidence from the ridge. So should see much less rainfall activity in the northern half of the CWA Thursday into Friday. At the same time, high temperatures will begin to increase closer to normal with decreased rainfall and cloud coverage and then surpassing climo with highs reaching mid/upper 90s late week to the weekend.

MEFFER

LONG TERM
(Saturday through Tuesday night)
Issued at 402 PM CDT Wed Jun 19 2024

Medium range models initially in decent agreement as we head through the weekend and then begin to has some disagreements in the details.
That said the differences are subtle and overall suggest expect the warmer muggy conditions to return with scattered afternoon convection. NBM is on the warmer side compared to the MOS numbers but is very close and given the possible setup not confident enough drop temps from the NBM. One change was to increase the morning lows at the typical warm spots this weekend around the lake.

As we kick the weekend off the ridge will continue to slowly retrograde across the Lower MS and become centered over the 4 corners by early next work week. Over the weekend this should keep rainfall potential on the low side with the best chance for any afternoon storms south of the 10/12 corridor likely associated with the seabreeze. Not anticipating the seabreeze making it that far north Saturday given the LL winds will remain out of the east or northeast but on Sunday there may be a slightly better chance of the seabreeze getting north of I-12 east of I-55 with slightly stronger southerly winds and up to h925. That said pops will still be in the 20 to 30% range for much of the area and with h925 temps hovering around 25-26C highs will likely range from the lower 90s in southwest MS to mid 90s most other locations. Sunday may be fairly similar with the highs and with increasing LL moisture there is a chance that the heat index values could jump up into the 100 to 108 range.

Early next week as the ridge continues to strengthen over the 4 corners with the ridge axis extending north into Canada the eastern periphery will start to tighten up and could place the region back under northwest to northerly flow. This would begin to favor convection once again but likely occurring very late in the day.
This would also mean we would see the rather warm temps continue as well. /CAB/

AVIATION
(00Z TAFS)
Issued at 650 PM CDT Wed Jun 19 2024

Outside of any residual showers, VFR conditions are anticipated through the cycle. Southeasterly or easterly winds will remain elevated through again today, especially closer to the coast.
There will be a chance of isolated showers and maybe a thunderstorm or two, but the lack of coverage and timing...will not add TS PROB or VCs for now. (Frye)

MARINE
Issued at 402 PM CDT Wed Jun 19 2024

Strong easterly winds in response to pressure gradient created by Alberto continue to impact the local coastal waters. Latest observations still show 20 to 30 knot winds with higher gusts over all marine areas other than the outer coastal zones. In those outer waters that are closer to the storm, winds are 5 to 10 knots stronger, hence the Gale Warning in effect there. Small Craft Advisory remains in effect for all other areas. These strong winds will continue drive water into to tidal lakes as well as all other eastern facing shores. No changes made to the current Coastal Flood Advisory in place but did extend the Coastal Flood Warning to include coastal Tangipahoa, Livingston, St Tammany and St John Parishes. Recent observations in Pontchartrain and Maurepas show that water is still steadily rising and now nearing 3 feet above where they typically should be. With winds not expected to slack off through the night, thinking those water levels will slowly increase and justify the upgrade to the warning. Winds should be at their peak and begin gradually relaxing with time later tonight through Friday as Alberto moves into northern Mexico. Non- impactful winds/seas expected through this weekend. This will help
