18z issuance... Visible satellite and observations show a broken
low-endVFR deck has developed across the whole area. A few
showers and thunderstorms are forecasted to develop along and
north of i-10 this afternoon and some instances of MVFR to ifr
conditions will be possible in the vicinity of any storms. Winds
will become southwesterly this afternoon becoming light and
variable tonight. Bb 03

12z issuance... MostlyVFR conditions through 19.12z. Could see
short periods of MVFR CIGS and visibilities in isolated showers
or thunderstorms this afternoon and early this evening followed
by some patchy fog near sunrise Fri morning. Winds will be
variable 5 knots or less early this morning shifting mostly
southwest at 6 to 10 knots late this morning through early this
evening, becoming light and variable late this evening through
19.12z. 32 ee
prev discussion... Issued 456 am cdt Thu jul 18 2019
near term now through Thursday night ... Mid to upper ridge of high
pressure that has built over the north central gulf coast region
and forecast area will begin to also shift northward today and
tonight. Near the sfc high pressure will continue to stretch from
the western atlantic to the SE CONUS and north central gulf coast
region through tonight. With this pattern better subsidence in the
boundary layer will continue today and tonight resulting limited
coverage of showers and thunderstorms across the forecast area
through tonight. Most of the model guidance show a well developed
seabreeze circulation developing by early to mid afternoon with
the best chance for measurable rain forming ahead along the
boundary by mid to late afternoon. Isolated light rainshowers will
also be possible over the adjacent gulf waters this morning
forming again in these areas near sunrise on fri. Due to limited
forcing and instability in the boundary layer the threat of severe
weather remains low to nil. Some patchy fog will also be possible
early this morning mainly over inland areas away with from the
coast, reforming again shortly before and around sunrise on thu.

With the better subsidence across the region daytime highs will be 3
to 5 degrees above seasonal norms. Highs today will range from the
mid to upper 90s for most inland areas and the upper 80s to lower
90s along the immediate coast. Lows tonight will continue to be
above seasonal norms ranging from the middle 70s for most inland
areas and the upper 70s to lower 80s along the immediate coast.

With a continue swell from the south combined with a tidal range
running about a 1.5 ft or slightly better a moderate risk for rip
currents will continue along the gulf beaches of al and nwfl through
tonight. 32 ee
short term Friday through Saturday night ... A mid level ridge
will be in place over the eastern portion of the country to the
north of our area through most of the period, but will be breaking
down somewhat by Saturday night as a mid level inverted trof
moves west across the gulf and southeastern states Saturday
through Saturday night. This mid level feature will result in a
more convectively favorable environment over the forecast area
than would otherwise be in place. Meanwhile, a surface trof will
be located along the east coast states and extending southwest
into ga al will remain in place with surface ridging noted to the
south over the eastern gulf of mexico. A very moist airmass
remains in place across our region through the short term, with
pwat's in the 1.60-2.20 range through the entire period. Combined
with MLCAPE values that increase to as high as near 2500 j kg both
Friday and Saturday this should be sufficient to produce scattered
to locally numerous showers and storms with daytime heating both
Friday and Saturday. The mainly afternoon convection will linger
into the evening each day, but coverages expected to decrease
during the overnight hours. The storms will move slowly in a
weakly sheared environment, and given the elevated precipitable
water values, this will trend toward locally heavy rainfall and
may lead to some nuisance flooding. Highs will be 90 to 95 over
interior locations on Friday but in the upper 80s near the coast.

Slight lower high temperatures are expected on Saturday. Heat
index values of 102 to 107 are expected on Friday, possibly
reaching heat advisory criteria of 108 degrees or higher in a few
locations. Lower values follow for Saturday due to the slightly
cooler daytime highs. Lows both Friday and Saturday nights range
from the low to mid 70s inland to the mid and upper 70s near the
coast. 12 ds
long term Sunday through Wednesday ... Digging upper trof over
the eastern portion of the country during the long term period
will bring a cold front down into the southeastern states by
Monday night and Tuesday. This, combined with the continued moist
and somewhat unstable airmass described in the short term period
will lead to a continued unsettled weather pattern over the area
through the long term period. Good chance to likely pops expected
each day with afternoon and evening showers and thunderstorms.

With the frontal boundary in the area, some lingering convection
will likely persist well into each overnight during the period.

Daytime highs still primarily in the 90s Sunday, but trending
downward somewhat through the remainder of the period. By Tuesday
and Wednesday highs are expected to only be in the 80s across the
region. Nighttime lows through the period primarily in the lower
70s inland and mid 70s along the coast. 12 ds
marine... High pressure will continue over the eastern and north
central gulf through the week leading to a light to moderate south
to southwest wind flow over the marine area mostly during the late
morning, afternoon and evening hours through much of the week. The
highest winds and seas will occur over the near shore waters out to
20 nm including inland bays and sounds during the afternoon and
early evening hours due to afternoon heating inland. Better rain
chances can be expected Thu through early next week as a weak trough
of low pressure slowly develops over the north central gulf coast.
