.SHORT TERM...
(Today through Thursday night)
Issued at 219 AM CDT Tue Apr 23 2024

High pressure remains the main factor influencing our weather and
will continue to be so through the middle of the week with clear
skies and calm conditions. 

Cold air advection will bring temperatures well below average
with highs 5 to 10 degrees below average. Highs today will still be
cooler than normal, with highs only in the low to mid to upper 70s.
This will be the last day before the 80s return along with more
humid conditions.Consistent warm air advection will increase on
Wednesday leading to a steady increase in temperature and
humidity. The increase in moisture will see an increase in fog
during the early morning hours. On Thursday a front will extend
across north Louisiana. This will increase our pressure gradient
and winds.

.LONG TERM...
(Friday through Tuesday)
Issued at 219 AM CDT Tue Apr 23 2024

As the forecast period begins, the forecast area will be under a
very warm and humid pattern with high pressure at the surface off
the southeast US coast ridging into the forecast area providing
southerly flow bringing in warm and moist Gulf of Mexico air.
Despite the moist air mass, upper level ridging will keep the
atmosphere capped, along with keeping the storm track well to the
north, and thus no significant shower activity is expected.

It will also become quite breezy on Friday as a deep low pressure
system will form over the Plains allowing for a tight gradient over
the region. Conditions will be close to advisory criteria with
sustained winds nearing 20 mph and gusts close to 30 mph.

The pattern will persist into Saturday with possibly an even
stronger low level jet that will allow for sustained southerly winds
in the 20 to 25 mph range with gusts over 35 mph, and if this
verifies, wind advisory criteria will be met.

By Sunday afternoon, the upper level ridge looks to shift a little
to the east. This will allow for a short wave to cut into the ridge
and move through the region late Sunday into Monday. The weakness
aloft and plenty of Gulf moisture will allow for a chance of showers
and thunderstorms during that time period.

.AVIATION...
(06Z TAFS)
Issued at 1120 PM CDT Mon Apr 22 2024

Light, variable winds are anticipated through at least sunrise
with high pressure in control. Surface high will continue a
movement to the east throughout the day Tuesday resulting in
winds prevailing from the south-southeast and south after 15Z.
Daytime winds will increase to around 10 to 12 kts with some
higher gusts in the mix from diurnal impacts. Winds decrease
after 01 to 02Z, but will remain from the south.

VFR skies with only some high cirrus are expected thru much of the
period. Southerly flow brings moisture and lower clouds in at BPT
towards the end of the period with all terminals seeing some lowered
VIS after 06Z.

.MARINE...
Issued at 219 AM CDT Tue Apr 23 2024

Winds are light and variable tonight but will become onshore
today. This onshore flow will remain light until the end of the
week. During this time waves will be less than four feet. Starting
on Thursday winds will start to increase becoming moderate to
strong. Waves will also build reaching 7 feet or more by Friday
morning.
