.DISCUSSION...See updated information for land areas below.

&&

.UPDATE...Rain chances have been increased for the remainder of the
morning based on the latest radar images and short term mesoscale
model output. Brief heavy rain and gusty winds will be the primary
threat through the afternoon hours. /13

.PREV DISCUSSION... /issued 703 AM CDT TUE JUL 12 2016/

DISCUSSION...Updated for latest aviation discussion below.

AVIATION...
12Z issuance...VFR to MVFR conditions through 13.12z. Lower cigs and
visibilities mainly in and around scattered showers and
thunderstorms through early this evening. Could see some patchy fog
near sunrise wed morning also. Winds will be light and variable early
this morning becoming mostly south at 5 to 10 knots late this morning
through this afternoon then light and variable later this evening
and overnight. 32/ee

PREV DISCUSSION... /issued 515 AM CDT TUE JUL 12 2016/

NEAR TERM /Now Through Tuesday night/...Persistent mid to upper
trof just to the west of the forecast area (fa) will continue to
weaken slowly and lift northeast with continued mid level energy or
forcing on the east side of the trof axis remaining about the same
through the next 24 hours. Latest proggs form both the gfs and ecmwf
suggest this better forcing will eventually pinch off and shift south
and west later this week. As a result expect a very similar pattern
compared to yesterday with increased coverage of showers and
thunderstorms over the adjacent gulf waters and along the coast early
this morning shifting inland over most coastal areas later this
morning and early this afternoon then further inland over most
interior sections of the forecast area by mid to late
afternoon...tapering off quickly by this evening as day time heating
is lost. Latest model soundings and meso analysis from spc show pwats
generally ranging from 1.7 to 1.9 inches across the fa this morning
continuing throughout the day with higher amounts occurring over
western sections of the fa covering most of southeast ms and extreme
western parts of the sw al. A weak cap at around 5 kft is also noted
over most inland areas this morning eroding by mid morning from
daytime heating and mixing suggesting increased coverage over lower
parts of the fa by mid to late morning. Similar to yesterday most of
the convection will remain below severe limits with maybe a few
isolated strong to marginally severe thunderstorms occurring by mid
to late afternoon...accompanied with damaging straight line
winds....frequent lightning and periods of very heavy rain. With the
higher moisture continuing in the boundary layer some minor
flooding...mostly localized in areas of poor drainage...will also
possible with some of the heavier showers and thunderstorms through
this afternoon.

Todays temps will continue to run a tad cooler then previous days
with highs mostly in the upper 80s to lower 90s. Tonights lows
will fall into the lower 70s inland and the mid to upper 70s
along the immediate coast. 32/ee

SHORT TERM /Wednesday Through Thursday night/...A slow moving upper
level trough axis will remain in the vicinity of western and
southwestern AL and adjacent east-central and southeast MS Wednesday,
while an upper level ridge of high pressure continues to stretch from
the central and eastern Gulf of Mexico through the FL Peninsula and
western Atlantic. The persistent upper trough in the vicinity of our
area, along with a continued moist airmass (precipitable water
values in the 1.75" to 2.0" range) and plentiful daytime instability
(MLCAPE values 1500-3000 J/KG) will support a continued chance of
showers and thunderstorms across the region Wednesday. Scattered
coverage should once again start out over southern portions of the
area during the morning, before gradually developing farther inland
by afternoon. Will keep 30-40% POPs in the forecast. Temperatures
should average close to seasonable normals with readings ranging
from around 90 near the coast to the lower to mid 90s inland.
Convection should dissipate by early evening, with expectation of
coverage falling to less than 20% after 7 PM. However, an isolated
shower or storm still cannot be entirely ruled out with the upper
trough axis remaining in the vicinity of the region. There is also
potential for isolated nocturnal re-development offshore and near the
immediate coast after midnight through the early morning hours Thursday.
Otherwise, mostly clear to partly cloudy skies can be expected with
overnight lows in the lower to mid 70s inland and 75-80 near the
coast and beaches.

A similar forecast continues Thursday, as the upper trough weakens
somewhat but still remains discernible in guidance from southwest AL
through southeast LA. This nearby feature along with a continued
moist and unstable airmass will allow for additional scattered
showers and storms spreading inland through the day. Coverage should
decrease after sunset. Little change in max/min temperatures is
expected, with highs once again ranging from around 90 to the lower
90s near the coast, with readings in the lower to mid 90s inland.
Lows Thursday night should mostly range from the mid 70s inland and
in the upper 70s to lower 80s near the coast and beaches. /21

LONG TERM /Friday Through Monday/...The weak upper trough axis
finally starts to retrograde westward Friday, while the upper level
ridge of high pressure meanwhile begins to build across the Central
Gulf Coast region this weekend into early next week. Despite the
building ridge, a moist and unstable airmass will remain over our
region through the extended period, with daily precipitable water
values looking to remain in the 1.75" to 2.0" range and MLCAPE values
mostly between 1500-2500 J/KG. We will therefore keep daily scattered
showers and storms in the forecast through the extended period. A
persistence forecast will also continue with regards to the daily
temperatures, as highs each day should range from around 90 near the
coast to the mid 90s inland, while lows each night range from the
lower to mid 70s inland and in the upper 70s to lower 80s near the
coast and beaches. /21

MARINE...A persistent surface ridge of high pressure stretching
from the western Atlantic to the north central gulf will continue to
weaken slightly through early wed in response to a weakening upper
level disturbance located over the lower mississippi river valley
slowly shifting north. As a result a light southeast to south wind
flow will continue over the marine area through wednesday becoming
mostly southwest and building slightly later in the week as high
pressure strengthens to the west. Little change in seas is expected
through the week...except locally higher near scattered showers and
thunderstorms continuing over the marine area through much of the
week. 32/ee
