Synopsis for pascagoula to atchafalaya river out 60 nm -
high pressure will remain across the local waters through midweek allowing for favorable marine conditions across the region. Winds will start to transition to a more southeasterly direction later today as the high moves east of the region. Going into the weekend, pressure gradient will tighten again leading to the need for cautionary headlines or small craft advisories.

Area Forecast Discussion...UPDATED National Weather Service New Orleans LA 1026 AM CDT Tue Apr 23 2024

New UPDATE

UPDATE
Issued at 1016 AM CDT Tue Apr 23 2024

High pressure continues to gradually spread east of the area this morning. This is allowing surface flow to veer to a more onshore flow across the region. Dewpoints have already responded slightly...through will remain steady or perhaps drop depending on mixing. That said, lackluster winds and the increase in RH values should limit fire weather potential this afternoon. Otherwise, nothing much to write home about with this midpoint update with only superficial changes to the ongoing forecast. (Frye)

SHORT TERM
(Today through Wednesday)
Issued at 328 AM CDT Tue Apr 23 2024

Forecast over the next few days and generally even into the weekend is quiet with the only real noticeable change being warmer temps and slowly increasing moisture. Clear skies and dry conditions have led to a rather cool night with most of the area in the 40s by 8z.

With one disturbance now well east of the mid Atlantic states and another s/w dropping across the Great Lakes today weak northwest flow will remain in place and this should provide us one more day of rather nice conditions. Only possible weather issue today could be rh values this afternoon which would mainly be a concern for fire weather customers but dewpoints are already a little higher than what models were indicating and even after we fully mix out this afternoon min RH values will likely still remain in the 30% range with possibly a few isolated spots dropping into the upper 20s.

Once the s/w over the Great Lakes moves into the northeastern states tomorrow we will see a stout ridge begin to build over the Plains and Continental Divide. That along with high pressure at the sfc pushing farther east will lead to southeasterly and southerly LL flow returning. LL temps will respond moderating quickly but moisture will take a little longer to recover through the week. LL temps could jump to around 16/17C at h925 by tomorrow and then could approach 19 maybe 20C by Thursday. This would translate to mid 70s to near 80 tomorrow and then lower 80s for most of the area Thursday. NBM again seems to be warming us up too fast with a few mid 80s tomorrow and possibly even upper 80s by Thursday. None of the MOS values are that bullish and the expected LL temps don't suggest that warm yet. Come Friday and maybe into the weekend those temps look a little more possible.

No rain expected through this time and the only other small impact to watch could be some fog tomorrow morning. LL moisture will be slowly returning but we should still have one last decent radiational cooling setup with lows in the 50s to lower 60s. /CAB/

LONG TERM
(Wednesday night through Monday)
Issued at 328 AM CDT Tue Apr 23 2024

Not a whole lot to talk about in the extended. The next few disturbances pass too far to the north and everything stays out of the region until early/mid next week when we finally see another shot of rain and a weak frontal passage.

Friday and through the weekend a series of disturbances will ride northeast form the 4 corners across the Plains and into the Upper MS Valley. These will all be displaced well off to our northwest and north. This keeps the ridging in place across the southeastern CONUS and what should be a warm weekend however, we will likely see a part of the subtropical jet break off and surge across the Lower MS Valley. If that occurs then we will see an increase in cloud cover with a decent layer of high clouds expected across the area.

After those disturbances through the weekend there should be enough of a push on the ridge to finally break it down and by late Monday into Tuesday we may see a trough pass through along with a weak cold front. This would bring us a shot of rain but nothing of any significant impact. /CAB/

AVIATION
(06Z TAFS)
Issued at 1140 PM CDT Mon Apr 22 2024

VFR conditions expected through the valid forecast period at all terminals. However, for the next forecast package at 12z, some consideration may need to be given to the potential for radiation fog at KMCB around sunrise Wednesday. While NBM probabilities of IFR visibilities are rather low, near 20 percent, that's quite a bit higher than the remaining terminals.

MARINE
Issued at 328 AM CDT Tue Apr 23 2024

The wind field will finally break down later this morning before we see a return of southeasterly winds late today or overnight.
This is in response to the sfc high moving over the area and then off to the east. No impacts expected for the next few days but late in the work week as the sfc high gets farther to the east we could see a few periods of moderate southerly and southeasterly winds close to the coast due to diurnal fluctuations. This may require brief periods of exercise caution headlines. /CAB/
