12z issuance...VFR conditions will prevail the next 24 hours
across the coastal sections, including all the TAF sites. Further
inland across southeast mississippi and a small portion of
southwest alabama, the patchy light fog and broken overcast low
stratus clouds will dissipate throughout the morning. Isolated to
scattered thunderstorms are expected to develop this afternoon
along and north of i-10, so added vicinity thunder to the tafs
from 23.21z to 24.01z, as most of the storms are expected to pass
north of the TAF sites. Light southeast winds will gradually
increase to around 10 knots by noon, and continue into early
evening. 22

Prev discussion issued 436 am cdt Thu may 23 2019
near term now through Thursday night ... A strong 500mb high
pressure system will remain centered over the southeast conus
through the near term, while a surface ridge of high pressure
remains over the southeast states and northeastern gulf of mexico.

Patchy morning fog, locally dense, and low status clouds, mainly
west of the alabama river, will burn-off through mid morning. Ir
satellite imagery and area metars are also detecting a scattered
to broken mid level cloud deck over the eastern portions of the
forecast area this morning that will pass westward across the
forecast area throughout the day.

After the fog and low status clouds burn off mid morning, much of
the forecast area will have mostly sunny skies to partly cloudy
skies today, leading to strong surface heating. With surface
temperatures reaching between 90 to 95 degrees by early afternoon,
mucape values (around 1000mb) will increase to between 1000 to 2000
j kg across southwest south central alabama and the western florida
panhandle, resulting in enough convective instability for afternoon
isolated to low-end scattered thunderstorms to develop. A weak sea-
breeze pushing inland may also trigger a few of the storms. While
the modified afternoon wet microburst sounding checklist indicates
an unlikely pre-storm environment for wet microbursts, the dry
subsidence air aloft is more indicative of a dry microburst to
potentially occur. Therefore, none of the storms are expected to be
severe, but gusty surface winds to 40 mph, along with locally brief
heavy rainfall, could occur.

High temperatures today will be as much as 10 degrees above normal
inland areas, ranging from 90 to 95 degrees. With southerly winds
off the gulf, highs along the coastal sections will be in the mid to
upper 80s. Light winds and remaining boundary layer moisture will
result in a combination of patchy to areas fog, locally dense, in
addition to low status to form again tonight. Low temperatures
tonight will be around 5 above normal, ranging from the mid to upper
60s inland areas, and from 70 to 75 degrees along the immediate
coastal sections. 22
short term Friday through Saturday night ... High pressure
continues to dominate the local forecast both at the surface and
aloft. Expect mostly clear skies and temperatures climbing into
the mid upper 90s inland and upper 80s to low 90s along the coast.

Some inland locations could top 100 degrees on Saturday, with heat
indices approaching 105 degrees as well. Please consider this if
planning any outdoor activities over the holiday weekend. Stay
hydrated and take frequent breaks in the shade to avoid
overexposure to heat. 49
long term Sunday through Wednesday ... Sunday and Monday will
be the hottest days of the long term forecast with inland highs
reaching 100 degrees and area beaches climbing into the low and
mid 90s. Heat indices continue to run close to 105 degrees and
necessary precautions should be taken for any outdoor activities.

Despite the upper ridge beginning to dampen and push east, we
remain under the influence of weak ridging extending from the
western gulf northeast into the western atlantic. This maintains
our hot and dry conditions through the first half of next week,
and while temps may not be as hot as the weekend, highs still
trend 7 to 10 degrees above normal for inland areas where mid to
upper 90s are forecast. There is some signal among extended range
guidance, however, that relief could be just over the horizon.

The east coast ridge is progged to break down enough for upstream
shortwave energy to approach the area sometime late next week,
bringing rain chances back to the local area Thursday and beyond.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
