Aviation
00z issuance...VFR conditions should generally prevail across the
region through the next 24 hours. Very patchy MVFR to ifr ceilings
and or fog may develop across interior portions of southeast ms
and southwest south central al late tonight into early Friday
morning, but probabilities of impact are currently low. Scattered
shra tsra are once again expected to develop near the coast Friday
morning, before spreading inland late Friday morning into Friday
afternoon. Localized lower ceilings and visibility reductions and
brief gusty winds can be expected in and near storms that develop.

South winds 5-10 knots early this evening become light and variable
through Friday morning, then southeast to southwest 5-10 knots
late Friday morning into Friday afternoon. 21

Prev discussion issued 352 pm cdt Thu aug 22 2019
near term now through Friday ... The upper level ridge extending
southwestward from the western atlantic over northern florida to
the central gulf of mexico will remain largely in place over the
next 24 hours. This upper ridge bisects two weak upper low
pressure areas, one over the western gulf and the other over the
bahamas. The western gulf low will move slowly northward through
the near term, while the bahama low moves slowly toward the
northwest. Our region will remain under the influence of the upper
ridge, so a diurnal precipitation pattern will persist. A
slightly increase in precipitable water values is expected over
the forecast area through the period, with values ranging from 1.8
to 2.1 inches overnight climbing to between 2.1 to 2.4 inches by
late Friday afternoon.

Current convection is expected to dissipate across the inland areas
by 11pm this evening, but isolated to scattered showers and a few
thunderstorms will re-develop mainly along and to the south of i-65
through the overnight hours. These showers and thunderstorms will
expand northward throughout the day Friday, becoming mainly
scattered in nature, but numerous showers and thunderstorms are
forecast west of the tombigbee river. Lows tonight will end up being
near to slightly above normal, ranging from 72 to 75 degrees, with
upper 70s along the immediate coastal sections. High temperatures
Friday will be near normal, ranging from 89 to 93 degrees inland
areas, but cooler along the coast in the mid to upper 80s due to the
earlier start of precipitation. The highest heat indices area-wide
will range from 97 to 103 degrees. 22
short term Friday night through Sunday night ... An interesting
upper level pattern unfolds over the region during the period. An
upper trof advances across the central and northern plains and
phases with a series of shortwaves generally over texas to form
an upper trof extending along the entire mississippi river valley
Saturday night into Sunday. Ahead of this upper trof, a western
atlantic upper ridge which initially extends weakly into the
extreme southeast states and northeastern gulf breaks down as a
series of shortwaves advance eastward across the central gulf
coast states. A weak frontal boundary initially located near
northern mississippi alabama advances slowly southward into the
forecast area through Saturday night as a large surface high
shifts across the interior eastern states and strengthens ridging
along the appalachians. The boundary lingers over the area through
Sunday, while deep layer moisture remains elevated through the
period with precipitable water values near 2.0 inches, about 125%
of normal. MLCAPE values are expected to increase to near 1500
j kg each afternoon while the environment remains weakly sheared
with high wet bulb zero values (14-15.5 kft). Expect to see
scattered to potentially numerous showers and storms develop over
the area each day with this pattern, possibly supporting higher
(categorical) pops over interior portions of the area by Sunday
after the frontal boundary moves into the area. Highs each day
range from the upper 80s to lower 90s while lows will be in the
lower 70s except for mid 70s at the coast. A low risk of rip
currents is expected through the period. 29
long term Monday through Thursday ... The upper trof advances
from the mississippi river valley across much of the eastern
states on Tuesday but also leaves a broad upper trof pattern in
place through Thursday over the northern plains and interior
eastern states. The weak boundary which was over the area on
Sunday may manage to linger into Monday before dissipating. An
associated surface low well to the north is expected to bring a
frontal boundary from the plains to across the mid mississippi
river valley on Tuesday. The frontal boundary weakens to a modest
surface trof while slowly shifting southward through the forecast
area to near the coast by Wednesday morning then into the northern
gulf Wednesday night. Expect scattered to numerous showers and
storms through Tuesday, after which coverage looks to be scattered
at best with the progression of the weak surface trof into the
marine area. Highs will be in the upper 80s to lower 90s while
lows range from the lower 70s inland to the mid 70s at the coast.

29
marine... A light and predominately southerly wind flow will continue
through Friday, becoming more southwesterly over the weekend through
early next week. Gulf seas will range between one and two feet
outside of thunderstorm activity. Shower and thunderstorm coverage
will generally be greatest from late night through noon each day.
