...New MESOSCALE UPDATE...

.MESOSCALE UPDATE...
Issued at 949 PM CDT Thu Jun 19 2025

The convection of the day has dissipated and no additional
convection is expected the remainder of tonight. Latest satellite
imagery/RAP analysis showed the shortwave trough axis east of
Mississippi and our CWA was on the eastern periphery of a 594dam
high centered over the Red River valley that will become dominant
over our region Friday. The Heat Advisory for portions of our CWA
will remain in effect for Friday. /22/

.DISCUSSION...
Issued at 236 PM CDT Thu Jun 19 2025

Rest of today through Friday...

An active period of storms remains ongoing across the area. Upper
air analysis earlier this morning indicates the region trapped
between ridging over the International Border in southwest TX and
and subtropical ridging over the western Atlantic. Water vapor
imagery and RAP analysis indicated the shortwave trough centered
across the Lower MS to TN Valley to Mid South area, aided in
development of mesoscale convective system (MCS) propagating south
to southwestward. This trough is aiding in mean west to
northwesterly flow, which is less favorable for balanced storms,
while storms in the northwest Delta moving into Bolivar have a
little more favorably aligned orientation to the background shear.
The MCS has continued to propagate southwestward, with the
northwest Delta storms more persistent and training potential. The
going hazard graphic for severe storm threat is on track, but
with such a southwestward propagation storms could end on the
earlier side. Rainfall rates have been extremely efficient in the
Delta, but narrowly confined to portions of the extreme northwest
Delta, where some +2-4 inches of rain have fallen. There will be
some continued localized flash flooding threat but confidence in
more areal coverage is lowered as the cold pool has become
dominant and radar intensities have waned somewhat from earlier
this morning. Southwest of the convection along and west of the
MS River corridor into northeast LA and southwest MS, some heat
indices have peaked in the 100 to 104F range.

For sensible weather elements, seasonable highs are expected (88-
94F), with seasonably warm in the Pine Belt. Scattered to widespread
showers and storms are expected in the Hwy 82 to Hwy 45 corridors
(55-85%), while more isolated to scattered to the south (15-55%).
Areas in the southwest will remain more isolated coverage.
Rain chances will wind down into early evening, with seasonably warm
lows overnight tonight, some 3-5F above (70-75F).

Friday: As the shortwave that was the impetus for recent rain and
storms propagates eastward, we will be on the eastern periphery of
building thermal ridge / 593DM mid level high to the west. This will
induce continue warm advection and southwesterly return flow picking
up to our west. This pattern supports increased heat concerns while
coverage of convection will be lowered and shunted further to the
east to southeast into the Hwy 45 to I-59 corridors. Dewpoints will
be abnormally higher in the 76-79F range, leading to increased heat
stress prior to or in the vicinity of any storm activity. Diurnal
microburst potential will remain as seasonably warm highs peak in
the 91-95F range. Heat stress will become increasingly a problem
beginning Friday. Based on that, expanded the Elevated for Friday
for heat stress concerns and added heat headlines for southeast AR
and portions of northeast LA, northwest, central and southeast
Mississippi from mid-morning through early evening Friday. /DC/

Relevant portions of the previous long term discussion is below:

Through next Wednesday: In the wake of the strong trough, there will
be more broad ridging pattern establishing itself over the area for
the remainder of the period. Since this pattern remains in place
diurnally driven energy will be the primary motivating factor for
the weather -- expect showers and thunderstorms by mid afternoon for
generally central to southeast portions of the area.
There is a chance for embedded/isolated cells to overachieve and
produce damaging winds and hail. Come sunset these
showers/thunderstorms will taper off leaving cool humid nights in
their wake.

That being said, in the current regime (hot and humid) expect heat
indices to continually break into the triple digits for most sites,
with the central corridor of the CWA seeing the highest temps.
Continued heat stress will be a concern through the weekend into
early next week. Areawide Elevated in HWO graphics remain relevant
through the mid to late portions of the following week. /OAJ/DC/
