Discussion
Current forecast is generally on target, so only some minor
adjustments were made based on latest guidance and observational
trends. Isolated showers areas of -ra will continue to spread east
across the area through the day, exiting the area completely by
late afternoon. Pops were reduced a bit from the previous
forecast to just slight chance low end chance. Drier air pushing
in from the west this afternoon will also yield thinning decreasing
cloud cover, especially over E tx into far W la.

Hazy conditions with generally light vsby reductions near the
coast and over the gulf waters may persist through the day amid a
lingering low level moist layer and ssts cooler than dewpoints. A
greater risk of fog formation will exist tonight, but will cover
that with the afternoon package.

scattered light showers continue to push across the region from
west to east this morning in response to a weak upper disturbance
and a surface low presently trekking across northern arkansas. The
low will continue off to the east through the day with drier mid
level air advecting in from the west. This will bring the
precipitation to an end by this afternoon with some breaks in
cloud cover expected across southeast texas.

These breaks will fill in once again late tonight into Friday in
advance of the highly touted cold front which will move into
southeast texas late Friday before continuing into southwest and
south central louisiana early Saturday morning. The latest
forecast soundings continue to forecast plenty of speed and
directional shear over the area in advance and in the vicinity of
what will likely be a developing squall line. The limiting factor
will be the somewhat anemic instability with highest forecast cape
values only around 500 j kg. Still, a few strong to severe storms
can't be ruled out and SPC has highlighted a day 3 marginal risk
area across south central and southeast louisiana.

Strong CAA still progged in the wake of the frontal passage
Saturday with high temperatures likely occurring early in the
morning. The lowest temperatures associated with this frontal
passage will still come Monday morning although most guidance
continues to modify what was once a large scale hard freeze event.

While freezing conditions are still expected across central
louisiana both Sunday and Monday mornings, temperatures are
expected to remain just above freezing along and south of the i-10
corridor.

Southerly flow redevelops during the day Monday in advance of the
next frontal features progged to move through late Tuesday into
Wednesday. There remains considerable disagreement amongst long
range models with regards to the timing of this feature with the
much faster GFS pushing the front through by Tuesday while the
euro and canadian are somewhat slower maintaining precipitation
across the area well into Wednesday. Continued to carry low end
pops Wednesday to account for this uncertainty.

On an administrative note, the klch radar has been experiencing
intermittent disruptions over the last 24 hours. Technicians are
aware of the issue, but disruptions may continue through the
morning or beyond until repairs are made.
