.SHORT TERM...
(Tonight through Tuesday night)
Issued at 240 PM CDT Sun Aug 18 2024
A strong ridge continues to control our weather pattern. Upper air
analysis shows high pressure centered over northwest Texas with a
ridge extending across Louisiana. To the north, a longwave trough
is centered over the Ohio Valley region. This high pressure and
its associated ridge will have the strongest influence over the
region for the next several days, with very hot temperatures and
minimal convection in the afternoon.
Monday we will see a slight decrease in temperatures as the ridge
begins to retrograde back to the west. However, hot weather will
continue, with heat advisories needed for most of the entire region.
Monday evening, a weak cold front will move across the region.
This will bring minor relief to our temperatures but will bring a
wind shift and additional rain. CAMs are hinting at an MCS with
this frontal passage, with widespread showers and thunderstorms
for Acadiana likely but minimal activity for the rest of us.
Tuesday will start off a little cooler than we are used to, as the
cold front will bring a north wind and will help drop down our dew
points a few degrees. Unfortunately, temperatures are still a few
degrees above the climatological norm. Around this time, the front
will stall along the coast. Creating a marginally favorable
environment for additional showers in the afternoon along the
coast, inland PoPs will be around 10%.

(Wednesday through next Saturday)
Issued at 240 PM CDT Sun Aug 18 2024
At midweek, the high pressure will still be centered over west
Texas, with its ridge still pushing well into our area. For the
rest of the week, the ridge will slowly begin to erode back to
the west while a cutoff low will begin to develop in the Gulf of
Mexico. In addition, the stalled front will keep our winds from
the north, drawing in lower dew points with low 70s along the
coast and the upper 60s farther inland. Winds will slowly shift to
the east near the end of the week, and we will see our dew points
start to climb again. But the good news is the lower dew points
will keep our heat index values below heat advisory levels we hope.
Late in the week and into the weekend, the cutoff low will move
across the Louisiana coast and will bring additional rainfall and
moisture to the region.

(00Z TAFS)
Issued at 621 PM CDT Sun Aug 18 2024
Light and variable winds and high clouds will continue area-wide
overnight. Tomorrow, a cold front approaching from the north is
expected to send some convection through the eastern parts of the
region, with showers/storms potentially affecting AEX/LFT/ARA
though the mid morning into the early afternoon. Model guidance is
not in good agreement on the timing/exact set up of this
convection so opted to just include VCTS for the possibility for
now. Elsewhere, VFR conditions continue.

.MARINE...
Issued at 240 PM CDT Sun Aug 18 2024
Weak high pressure is the main weather feature on the Gulf Coast,
with light winds and calm seas. Isolated showers and
thunderstorms will be possible overnight and in the early morning
hours.
On Monday, a weak cold front will stall along the coast and
become stationary on Tuesday or Wednesday. This feature will
weaken offshore flow with increased convection across the coastal
waters.
