.DISCUSSION...

Today & tonight:

Warm & mostly dry afternoon can be expected, with the exception in
the far south & southwest in the Highway 84 corridor & extreme
southern portions of northeast Louisiana. Dry air is entrenched over
the area with mid-level ridge axis centered over or just east of our
area. GOES East imagery this morning shows nearly an inch or less
PWs centered over the heart of the region, with any deeper moisture
to the west & far south into the Gulf. Due to broad scale subsidence
& capping in forecast soundings, expect a quiet & warm afternoon,
with some clouds & a few passing warm advection late afternoon
showers & storms possible across the south. Above normal warmth in
the upper 80s to low 90s is possible, especially across the
ArkLaMiss Delta, but we should be able mix dewpoints out enough to
limit the humidity.

High pressure at the surface & aloft over & east of our region will
keep subsidence & drier air locked in the region. This will keep
quiet conditions overnight. Expect near normal lows in the east to
slightly above normal lows in the west under mostly clear to clear
skies. /DC/

Sunday through Friday:

High pressure aloft will maintain its overall grip on the weather
across the region through much of the forecast period. By the
middle of next week, the high will weaken enough to perhaps allow
a cold front to sink south into the far northern portion of the
forecast area Tuesday. However, models currently indicate that
will be as far south as the front makes it. From there, it`ll
begin to wash-out as it lifts off to the northeast on Wednesday.

Therefore, the above normal warmth is currently expected to continue
across the region through the period.  With the aforementioned cold
front dropping into the region, there will be an increase in rain
chances across a good portion of the CWA on Tuesday.  Moisture
continues to subtly increase Wednesday through Friday, also aiding
in the chances for mainly isolated showers and storms across the
area.  These will remain confined to the afternoon and early evening
hours. /19/

06Z TAF discussion:
VFR conditions can be expected through next 24 hours. Other than a
some low-level cumulus around 5-7kft & high level cirrus, no
flight restrictions can be expected. Winds will mainly be out of
the east-southeast around 5-10mph, with winds becoming light into
the evening. /DC/
