...New SHORT TERM, LONG TERM, AVIATION, MARINE...

.SHORT TERM...
(This evening through Saturday night)
Issued at 239 PM CDT Thu Aug 24 2023

Little change in the overall pattern is expected through the end
of this week as a strong deep layer ridge remains centered to the
northwest of the CWA across the southern Plains and Texas. The
region will reside on the southeastern periphery of the high, and
this will allow for a bit less subsidence and bit more cooling
aloft. The main result from this will be a slight increase in
instability as reflected by MLCAPE values of 500 to 1000 J/KG each
afternoon, and a resulting increase in cloud development and
thunderstorm risk. PoP grids reflect this increased convective
threat with values of 20 to 30 percent each afternoon.
Despite the slight weakening of the ridge aloft and slight
increase in convective development, temperatures will remain well
above average as dry low level conditions allow for rapid heating
each day. Highs will easily climb into the upper 90s and lower
100s, and more record highs are likely to be set on Friday and
Saturday. These dry conditions will also limit heat index values
to around 110 degrees, and conditions will be more supportive of
heat advisories both Friday and Saturday instead of the excessive
heat warnings seen the past several days. The drier air will also
push relative humidity values down to near 30 percent each
afternoon. Given the dry fuel conditions in place, the low
humidity and winds of near 10 mph has resulted in additional red
flag warnings for tomorrow over most of Southeast Louisiana and
all of southern Mississippi.

&&

.LONG TERM...
(Sunday through Wednesday night)
Issued at 239 PM CDT Thu Aug 24 2023

Little change in the overall pattern is expected on Sunday with
another day of highs near 100 and widely scattered afternoon
convection anticipated as a deep layer ridge axis remains centered
to the west and northwest of the CWA. However, conditions will
begin to transition on Monday as a northern stream trough axis
begins to deepen over the eastern CONUS. The ridge will slide
further to the west, and overall subsidence will decrease across
the Gulf South. Temperatures in the mid and upper levels will also
begin to cool, and this will allow for an increase in overall
instability. MLCAPE will peak at between 1000 and 1500 J/KG, and a
more typical pattern of scattered pulse convective development
along weak mesoscale boundaries like the seabreeze is expected.
Unfortunately, this will not lead to a decrease in low level
temperatures as dry ground conditions allow for rapid heating in
the morning and early afternoon hours. Highs will easily jump into
the upper 90s and lower 100s, and heat indices will continue to
range near 110 degrees both days.

A full pattern change is expected on Tuesday and Wednesday as the
the northern stream trough axis fully deepens and potential
tropical cyclone advances through the eastern Gulf and toward
Florida. The combination of these features will allow for a fairly
strong frontal boundary to slide through the forecast area on
Tuesday and Wednesday, and a decrease in temperatures and increase
in rainfall is currently in the forecast. Temperatures should cool
back to more average levels in the lower to middle 90s, and heat
index values are expected to finally fall below advisory levels at
around 100 to 105 degrees. Deeper moisture along the front will
push precipitable water values over 2 inches, and cooling in the
mid and upper levels will also increase MLCAPE to around 1500
J/KG. As a result, deeper and more sustained convective updrafts
will support scattered to numerous shower and storm activity both
Tuesday and Wednesday afternoons. Overall, a return to more
typical Summer pattern is anticipated next week.

&&

.AVIATION...
(18Z TAFS)
Issued at 239 PM CDT Thu Aug 24 2023

No significant impacts to aviation operations are anticipated
through the forecast period as a strong ridge of high pressure
continues to suppress convective development. As a result,
prevailing VFR conditions are expected at all of the terminals
through tomorrow afternoon.

&&

.MARINE...
Issued at 239 PM CDT Thu Aug 24 2023

Through the weekend, continued benign conditions are anticipated
over the coastal waters. Winds will be light at 10 knots or less
and seas of 2 feet or less are expected as high pressure
continues to dominate the Gulf Coast. However, conditions may turn
more volatile next week if a tropical cyclone develops in the
southeastern or eastern Gulf of Mexico. Although direct impacts
are not currently anticipated, there could be some large swell
that moves into the water and produces higher and rougher sea
conditions. The evolution of this potential tropical cyclone
development early next week will continue to be monitored.
