.DISCUSSION...
Issued at 356 AM CDT Thu Jun 26 2025

Today and Tonight: Local radars were lit up early this morning with
an area of convection that moved into eastern Mississippi on an
outflow boundary from vigorous convection to our east. The outflow
boundary was noted approaching Interstate 55 north of Interstate 20
and will likely stall nearly along I-55 by morning. Although the
convection was weakening and will likely dissipate by sunrise, rain-
cooled temperatures and residual cloud cover place some doubt in
heat index values reaching 105F over the eastern half of our CWA
today where a Heat Advisory remains in effect. Surface ridging has
shifted south over our southern zones and will remain in place
through tonight. Ridging aloft remains to our north with a mid level
low also noted over the Florida peninsula. The ridging surface and
aloft will help maintain above normal temperatures through tonight
but the flow around the mid level high to our north and the mid
level low to our east will result in a deep easterly flow across the
region. This will help convection track to the west across our CWA
again today and mostly during the heat of the day. The stalled
boundary splitting our CWA in half may help initiate convection this
morning but it will take peak heating this afternoon to raise the
potential for isolated severe storms capable of damaging wind gusts.
This severe storm threat is expected to decrease during the evening
and currently all precipitation is expected to end by midnight.

Through mid next week...

Midlevel high continues to be situated over the TN Valley with
easterly flow on the south side over our area. This has allowed
storms to propagate east to west, aided by a hot and humid airmass.
An ongoing complex associated with an upper low feature over Alabama
looks to only clip the Golden Triangle and remain subsevere as it
propagates northeastward), as better lapse rates are situated over
Alabama. Latest CAM guidance suggests the remnant outflow boundary
from this complex pushing across our area this morning and refiring
in the afternoon. Therefore, have adjusted PoPs up in the west,
where the boundary is likely to be situated. Will carry PoPs through
the afternoon and evening as reasonably storms have continued to
maintain beyond sunset.

As the midlevel high breaks down and propagates east, a weak upper
low will migrate towards our area, and steadily increase rain
chances, with highest chances in the east. A statistically
significant tropical moisture plume associated with this feature
becomes compressed as a trough to the north digs across the Ohio
Valley. This in turn allows for a ridge over Texas to amplify,
setting up W/NW flow over the area. The pattern looks hotter amid
deep tropical moisture with upper 70s dewpoints. I suspect that heat
will creep up once again next week towards the back end of the
period. May have to consider additional heat advisories next week
and will assess day to day. Additionally with the hot
temperatures combined with a 2.5 inch PWAT airmass, will have to
monitor day to day for microburst potential. Such moisture will
keep rain and storm chances in the forecast through the
period./SAS/
