.SHORT TERM...
(Today through Friday)
Issued at 228 AM CDT Thu Apr 17 2025

Old frontal boundary is now oriented north south over central
Louisiana this morning. Southerly winds with a larger vertical depth
found to the west of this boundary transporting plenty of moisture
northward. We will continue to enjoy nice conditions while we remain
to the west of this boundary, but it will dissipate over the next
few days. Southerly winds will also begin to rise across the areas
today and Fri but won`t get high enough to keep the heat away as we
will also tack on several degrees between today and Fri and it would
not be a surprise to see our first 90F somewhere in the area. No
issues in the short term.

.LONG TERM...
(Friday night through Wednesday)
Issued at 228 AM CDT Thu Apr 17 2025

Temps will fall back by a few degrees over the weekend as winds
should be high enough to ventilate the column. Another front will
move through into LA/MS by the weekend and stall before reaching the
coast Monday. We should see plenty of sh/ts associated with this
boundary and this should give us at least a higher chance of rain
starting Sunday through Tue. Most of the severe weather variables
are not very high as this system approaches Sunday. But they are
enough to at least introduce the possibility of an isolated severe
storm. The deep dry slot at H7 is situated perfectly to help cause
downbursts if any cores can take advantage of it. The front should
stall north of the coast while deep moisture remains which will help
keep rainfall chances high enough that most areas should see some
rain, which will be needed by that time. The stalled front will
begin to move back north by Mon night into Tue. This will leave our
area in a deep moisture environment along with CAPE values in and
around 1kJ. This should be enough to keep a few sh/ts going each day
during the afternoons. A short wave may move through the zonal flow
over the area by Wed and Thu and this could be a little more
interesting since we are still in MCS season.

.AVIATION...
(12Z TAFS)
Issued at 228 AM CDT Thu Apr 17 2025

There could be some MVFR cigs move into the western areas mainly
for BTR to MCB late tonight. Otherwise, VFR this taf cycle.

.MARINE...
Issued at 228 AM CDT Thu Apr 17 2025

SE winds will become more stable today rising to around 15kt over
the weekend. Showers and maybe a thunderstorm could move over the
coastal waters Sunday and Monday. Wind speeds will likely approach
20kt over the weekend and this may cause headlines to be introduced.
Wind speeds will lower back to around 10kt by Mon but SE fetch will
remain well into next week.
