.SHORT TERM...
(This evening through Friday night)
Issued at 344 PM CDT Thu Jun 26 2025

Broad upper level ridge that was nearly overhead has slid farther
east and is beginning to breakdown. Since that hasn`t completely
happened yet, still seeing a mix of convective development with
coverage on the lower side of average for summertime as well as
quite warm temps. CAMs are not particularly reliable for where
storms are/will develop but probably decent on timing and duration
of when we`ll have the most activity between now and midnight
tonight.

.LONG TERM...
(Saturday through Wednesday night)
Issued at 344 PM CDT Thu Jun 26 2025

The upper ridge over the southeast US will become just broad weak
high pressure over the southern  half of the country tomorrow into
the middle of next week.  That setup will yield little appreciable
subsidence to limit convection, especially with highs in the 90s and
PW`s over 2". The POP forecast reflects this transition to a wet
pattern with coverage around 50% Friday and at least 70% for the
remainder of the 7 day forecast period. The 2 main impacts to
monitor with storms will be downbursts and localized heavy rain.
DCAPE looks to be pretty decent each day over 500j/kg which comes
from typical summertime T/Td profile in the column. For the heavy
rain...thats mainly just a result of weak steering pattern as well
as the seemingly infinite outflow boundaries that`ll be produced
which sometimes aides in repeated rain over a location.

.AVIATION...
(18Z TAFS)
Issued at 344 PM CDT Thu Jun 26 2025

VFR outside TSRA through this cycle. TSRA chances will be a bit
higher today, but mainly along and north of a line from KASD to
KBTR. Did add some PROB30 groups for those terminals.

&&

.MARINE...
Issued at 344 PM CDT Thu Jun 26 2025

Surface ridge will be centered over the eastern Gulf of America over
now into next week. Since not chance of a cold front coming into the
region attm, gradient winds will generally be stable and relatively
weak at 10 kts or less. The bigger impacts, albeit more localized,
will come from daily thunderstorms. Boaters should be congnizant of
developing storms as they can often produce gusts in the 25 to 40
knot range.
