...New SHORT TERM, LONG TERM, MARINE...

.SHORT TERM...
(This evening through Tuesday night)
Issued at 328 PM CDT Mon Apr 15 2024

Upper ridging axis curves from the northern plains, through
the central midwest, and into the northwest gulf. A low pressure
sink is centered just north of the four-corners. Surface high
pressure over the western Atlantic extends into the western Gulf
and southern States. As we move through the short term, the low
moves over the upper midwest trailing a frontal boundary that
should be maturing but forced by the high pressure over the Gulf to
sit north of us by the end of the short term.

We will see pleasant temperatures and dry weather, although a high
cirrus canopy predominates the sky. Mild Winds will be out of the
southeast to south building to 15mph by the end of the short
term.

.LONG TERM...
(Wednesday through Sunday night)
Issued at 328 PM CDT Mon Apr 15 2024

As we move into and through the long term, the upper low continues
to the northeast and breaks down by late in the week. The
attendant front stays north of us leaving an early season
zonal pattern maintaining warmer that normal temperatures at the
end of the week. (NBM guidance actually has near record highs in
Baton Rouge, which just doesn`t seem likely so dropped the high
temp grid slightly on Friday.) At the very end of the period a
weak shortwave trough brings some moisture and possibility of
rain into the area. Chances look better on Sunday at this time,
but do exist on Saturday.

.AVIATION...
(18Z TAFS)
Issued at 1213 PM CDT Mon Apr 15 2024

Little in the way of clouds expected for the daytime hours today,
but likely to see cirrus level clouds increase in the evening.
With low level moisture expected to continue to increase overnight
tonight, most terminals expected to see MVFR to IFR ceilings to
develop beyond 06z Tuesday, probably closer to 10z. Those ceilings
would be expected to improve by mid-morning Tuesday. Around
sunrise Tuesday expect BR at KMCB with VIS at 1SM and at KHUM at
6SM. Southeasterly winds will start to become more prevalent this
afternoon with most terminals near or above 10 knots, with
somewhat stronger winds anticipated during the daytime hours
Tuesday.

.MARINE...
Issued at 328 PM CDT Mon Apr 15 2024

Marine conditions will be relatively quiet with winds out of the
southeast to south. A short Small Craft Exercise Caution headline
is in place for late tonight into early morning highlighting the
likelihood of winds just above 15kt in the southwestern offshore
marine zones. Another short period of elevated winds early
Wednesday morning may require the SCEC, also.
