.KEY MESSAGES...
Issued at 614 AM CDT Sun Apr 26 2026

 - Isolated to scattered thunderstorms are anticipated on Sunday.
   A few may become strong and produce gusty winds.

&&

.UPDATE...
Issued at 630 AM CDT Sun Apr 26 2026

A couple of loosely organized mesoscale systems currently moving
across the Natchez Trace near Jackson, MS, continue to move
southeast towards the forecast area. These systems should reach
the western fringes of the forecast area in 2-3 hours. Ground
truth so far has been 30-35kts, and am expected to remain at these
levels as they move southeast along an instability gradient over
southeast Mississippi.
/16

&&

.DISCUSSION...
Issued at 1159 PM CDT Sat Apr 25 2026

An upper ridge building into the region looks to support dry conditions
for Monday. An MCS approaching from the west overnight weakens in
response to encountering the developing upper ridge, though looks
to bring isolated to scattered convection into southeast
Mississippi and extreme southwestern Alabama during the early to
late morning hours on Sunday. A weak frontal boundary also settles
into the area on Sunday and am anticipating that isolated to
scattered convection will manage to develop over much of the area
during the afternoon hours in response. A few strong storms are
possible with gusty winds as the main threat. A large positively
tilted upper trof will be in place over the western and north
central states on Sunday, then an embedded system ejects off
across the Great Lakes region through Sunday night. A broad upper
trof pattern evolves over much of the northern states by Tuesday,
with the upper ridge over the forecast area meanwhile weakening
and being deflected off to the east. The upper trof becomes
oriented mostly over the interior eastern states by Thursday. A
series of shortwaves move across the forecast region in the
process, and a surface low is expected to bring a cold front
through the forecast area mainly from Wednesday afternoon into
Wednesday evening. With the series of shortwaves moving across the
area and the frontal passage, have gone with slight chance to
chance pops over interior areas on Tuesday increasing to chance to
likely pops by Wednesday night. May see some strong storms
develop mainly from Tuesday night into Wednesday evening, but
otherwise shear values look to remain generally low.

A series of shortwaves continue to move across the forecast region
Thursday into Friday, with the frontal boundary meanwhile drifting
back into the forecast area. There is a lot of uncertainty past
this point, with the potential for a Gulf surface low to pass
nearby the forecast area roughly on Saturday. Have for now
continued with mostly chance pops for Thursday and Friday, then
chance pops follow for Saturday and will continue to evaluate. A
low risk of rip currents is expected for Sunday through Thursday.

.AVIATION...
(12Z TAFS)
Issued at 630 AM CDT Sun Apr 26 2026

General VFR conditions over the forecast area will see local drops
in CIGs/VISBYs to MVFR levels due to another round of showers and
thunderstorms are expected this morning into this afternoon with
local drops to low end MVFR levels possible.
/16

&&

.MARINE...
Issued at 1159 PM CDT Sat Apr 25 2026

A light to occasionally moderate onshore flow will prevail through
Wednesday. Winds become northerly Wednesday night as a cold front
moves through, then gradually transition to a predominately easterly
flow for Friday. /29
