.SHORT TERM...
(Through tonight )
Issued at 1238 PM CDT Thu Jul 10 2025

Hot and humid conditions will persist into early this evening
with Heat Advisory continuing through 8 PM for parts of eastern OK
and west central AR. Isolated showers and thunderstorms remain
possible later this afternoon within slightly deeper moisture from
west central AR into southeast OK. Brief and isolated instances
of heavy rainfall are possible, along with some potential for
strong downdraft winds before convection wanes with loss of
daytime heating.

.LONG TERM...
(Tomorrow through Thursday)
Issued at 1238 PM CDT Thu Jul 10 2025

Impacts of an upper level trough moving across the Central Rockies
will begin Friday as deeper moisture is drawn back northward in
response. Generally expect another hot and humid afternoon Friday
with heat indices again topping out in the 100-105 range for parts
of eastern OK and west central AR. By afternoon, modest height
falls spread east into areas near OK/KS border with some CAMS
indicating isolated development into areas W of US 75. Higher
chances of showers and storms though will be later Friday evening
as frontal boundary moves closer to the region.

Presence of this boundary and a slowly progressing trough will
maintain scattered to numerous showers and storms through the
weekend, with focus of coverage generally expected to shift
southeast with time. Precipitable water values analyzed over 2
inches currently across much of east TX will be drawn north,
likely pooling near the frontal zone, and enhance the potential
for pockets of heavy rainfall. While a widespread heavy rain event
is not expected, conditions will favor isolated amounts in the
3-5" range which would lead to localized flood potential. A few
damaging wind gusts will also be possible if more organized
clusters develop as upper trough passage leads to a modest
increase in deep layer shear.

Overall precip chances diminish some next week with weak ridging
in the wake of weekend system. Another and possibly stronger front
is forecast to move toward the region during mid to late next
week, once again raising shower and thunderstorm chances across
part of the area, and keeping temperatures a little below average.

(00Z TAFS)
Issued at 620 PM CDT Thu Jul 10 2025

VFR conditions are expected through the period. Southerly winds
will calm some overnight, before becoming gusty again tomorrow
afternoon with some gusts around 20 knots possible out of the south
to southwest. Otherwise, scattered mid to high clouds can be
expected through the period. An isolated shower or storm could
develop across NE OK sites late in the period but chances are too
low to mention. Better rain chances will move in beyond this TAF
issuance.
