.SHORT TERM...
(This evening through Sunday night)
Issued at 1243 PM CDT Sat May 31 2025

Weak high surface pressure will remain in place through the
remainder of the weekend keeping the weather generally quiet. The
biggest question is whether isolated to widely scattered showers
will pop up late Sunday afternoon into Sunday evening as a fast-
moving upper disturbance barrels into the area embedded within the
overall upper trough axis.

Since the timing looks to coincide with peak daytime heating, it
seems we should see at least a few showers develop as the
shortwave moves into and through the area. And indeed, most CAM
guidance agrees on this scenario, though the specifics are quite
varied. That being said, have continued to carry generally 15-20%
POPs to account for the low-end, location-specific rain chances.

Regarding temperatures, expect lows in the mid to upper 60s north
and upper 60s to lower 70s south, with highs rebounding into the
upper 80s on Sunday. This is near normal for this time of year.

.LONG TERM...
(Monday through Friday night)
Issued at 1243 PM CDT Sat May 31 2025

An elongated upper high will control the area weather Monday and
Tuesday leading to generally quiet conditions and a gradual
warming trend as surface high pressure slides east of the local
area with warm and moist air moving back into the area from the
Gulf. Expect temperatures to be near or slightly above normal with
no significant rain chances.

The upper high begins to break down Wednesday as a fast-moving
upper disturbance moves toward the middle Mississippi valley. The
front associated with this system will stall WELL northwest of the
area, keeping us entrenched in a warm and humid airmass. Expect
to see typical summer-like showers and storms mainly during the
afternoon and early evening hours driven by the diurnal heating
cycle.

Beyond Friday, please resist the urge buy into any individual
model forecasts regarding a tropical low that may or may not form
around central America during the second week of June associated
with the Central American gyre (CAG). The CAG is a seasonal area of
low pressure that typically forms near Central America during the
May-June timeframe. Tropical lows associated with the CAG can
develop on either the Pacific or Atlantic side of the continent,
and their specific genesis locations greatly affect their eventual
paths. With that said, there is little to no confidence 7+ days
out regarding whether or where the CAG might result in
cyclogenesis. Remember to make sure you are following reliable
sources for your weather information.

.AVIATION...
(18Z TAFS)
Issued at 1223 PM CDT Sat May 31 2025

VFR conditions will prevail through the period as high pressure
results in mostly clear skies and light winds.

&&

.MARINE...
Issued at 1243 PM CDT Sat May 31 2025

A stalled boundary over the northern Gulf will keep winds light
and somewhat variable today. The front will move northward again
Sunday with a return to onshore flow. As the gradient gradually
tightens, expect wind speeds to slowly strengthen to 10 to 15
knots by midweek. Rain chances will generally remain low for the
remainder of today and tomorrow, but will gradually increase
through midweek with a return to daily scattered showers and
storms Wed through Fri.
