.SHORT TERM...
(Today through Monday night)
Issued at 300 AM CDT Sat May 31 2025

Surface analysis this morning shows a stalled front draped along
the northern Gulf Coast, while high pressure is over the Southern
Plains. Aloft, the forecast area is situated beneath a NWrly flow,
with an amplifying trough over the Eastern Seaboard and ridging
over the western CONUS. Today, a small shot of drier air behind
yesterday`s front will yield a dry and seasonal start to the
weekend, with highs reaching into the mid 80s amid mostly sunny
skies. Dewpoints will continue to slowly fall through the next few
hours, and should be mainly in the low to mid 60s throughout
today, resulting in RH values generally around 50% today.

Overnight into Sunday, surface winds become light and variable
before eventually returning to a SWrly flow, resulting in a return
of lower 70s dewpoints. While moisture returns in the lower
levels, a dry NWrly flow continues for a bit longer aloft. Late
Sunday, a shortwave is forecasted to dive south across the MS
Valley, inducing showers and storms as it does so. Models have
come into slightly better agreement since yesterday, and are
trending towards a drier solution for the forecast area with this
shortwave. While isolated showers/thunderstorms are definitely not
out of the question for Sunday afternoon/evening, it`s looking
like a sunny and warm day overall.

Moving into the new work week, weak upper ridging builds across
the Plains/MS Valley, while surface high pressure establishes
itself over the eastern CONUS. This will transitions us towards a
more typical summer time pattern, with a constant fetch of
moisture into the region resulting in isolated to scattered
showers and thunderstorms during peak heating hours. In addition,
daytime highs return to the upper 80s to low 90s.

.LONG TERM...
(Tuesday through Saturday)
Issued at 300 AM CDT Sat May 31 2025

A typical summer time pattern continues as we move through the
long term period, with little day to day changes expected through
the week. At the surface we remain on the western periphery of
high pressure, keeping south to southeast winds in place. Aloft,
ridging shifts towards the Midwest/New England Tues into Wed and
becomes elongated across the Gulf Coast towards Mexico, while
weak troughing takes shape over the Rockies/western Plains. This
will allow for some weak perturbations to move across the Ark-La-
Tex in the flow aloft, helping to provide a bit of supper for
daily showers and storms. How this will affect the forecast area
will depend largely on the strength of the ridge overhead, with
the GFS and Euro continuing the differ. For now, expect slightly
higher rain chances Wed-Fri afternoon, but still not a wash
out/significant chance of rain by any means. Apart from daily rain
chances, hot and humid conditions continue with highs reaching
into the upper 80s to lower 90s each afternoon.

(12Z TAFS)
Issued at 609 AM CDT Sat May 31 2025

Light north winds continue through around midday, followed by
light and variable to near calm winds through the remainder of the
forecast period. Broken mid-level clouds along and south of I-10
this morning will gradually clear out through midday, giving way
to a mixture of scattered high clouds and clear skies through the
rest of the day/tonight.

.MARINE...
Issued at 300 AM CDT Sat May 31 2025

A brief period of offshore winds will continue through today
behind a weak cool front currently in the coastal waters. Later
in the weekend, a surface high will build across the northern Gulf
into the coastal waters that will provide a return to southerly
winds on Sunday. This high looks to stay in place into next week
keeping a light to occasional modest onshore flow in place. There
will be a daily chance of mainly scattered showers and a few
