.DISCUSSION...
Issued at 220 AM CDT Fri Jun 6 2025

Through Tonight: This morning our area is at the interface
between suppression associated with a mid level ridge extending
from the western Gulf into the Lower MS Valley and a regime of
more active flow from the Great Plains through the Ohio Valley to
New England. This should result in generally drier conditions over
central and southern portions of the area with more opportunity
for passing shortwaves to result in shower activity over the
northern portion of the area. For today, most CAM guidance
suggests suppression will win out in most areas with mostly dry
conditions over the coming 24 hours, except along the US 82
corridor and over northeast/far east MS where there is greater
potential for development. The key mesoscale feature in the near
term will be an MCS evolving eastward from OK into AR early this
morning. Most guidance weakens this system before it reaches the
MS River, but even so, the outflow/ remnants could serve as a
focus for redevelopment farther east this afternoon. Given
marginally supportive deep shear and moderate to strong
instability, a few severe storms cannot be ruled out across mainly
northeastern portions of our area on the periphery of the upper
ridging. Damaging winds would be the primary threat.

This weekend: The ridging will begin to retreat with the more
active mesoscale storm track nudging further southward into our
area potentially as early as late morning Saturday. During the
time period from Saturday through Sunday and potentially
continuing into Monday, multiple periodic convective complexes are
expected to traverse our area, with potential for severe storms
given instability that is strong at times and deep shear that will
be generally sufficient. Within this type of regime, convection
may persist into nighttime and early morning periods given
lingering moderate instability within our muggy airmass. Again,
damaging winds will be the greatest threat with any severe storms.
We will continue to highlight severe potential during this time
frame in the HWO graphics.

Next work week: A front will sink southward and stall across the
Deep South. While this will provide some level of heat/temp relief
over much of the area, it will also keep greater rain chances
around through the remainder of the forecast period, with higher
coverage generally more favored during the daytime periods.

Heat stress: Before rain and the approaching front provide a
break from the current above average temps and humidity, heat
indices will have the potential to breach the triple digits both
today and Saturday. The experimental NWS HeatRisk is highlighting
the potential for greater impacts especially along and south of
I-20. Given these factors including the early season timing and a
weekend period in which people are more likely to be outdoors, we
will highlight a limited heat stress threat over roughly the
southern half of the area. /DL/

(06Z TAFS)
Issued at 1223 AM CDT Fri Jun 6 2025

VFR conditions will prevail through the TAF period. Brief
lowering of categories possible at PIB & HBG between 06/10-13Z due
to some low stratus/fog concerns but probs were to low to mention
in TAFs. Some showers and isolated storms will be possible
Friday, with only low probs (35-55%) to only mention between
06/19-23Z at GTR & MEI./KP/
