.KEY MESSAGES...
Issued at 1232 AM CDT Tue Aug 12 2025

 localized relief from short term rainfall deficits.

-Near normal temperatures will be seen through Wed/Thu before
 increasing to well above normal values for the weekend into next

.DISCUSSION...
Issued at 1232 AM CDT Tue Aug 12 2025

H500 trough making slow progress eastward across the middle of the
country will continue to influence local conditions through at
least Thursday. This feature will keep mid-level ridging in place across
the SE and SW US at bay. As the trough continues to move east it
will provide an increase in precip development across the state,
especially during the afternoon/evening hours. Additionally, like
what has been observed overnight, some precip may persist through
the overnight hours as lingering/remnant boundaries aid in precip
longevity.

With the overall flow remaining meager and PW values in
the 1.50-2.00 inch range or higher, some locally heavy downpours
can be expected. Coverage overall should remain limited, which
will do little to improve shortfall rainfall deficits. But, some
areas will receive locally beneficial rainfall.

By late week into the weekend, the mid-level trough will be well
east of the region. In its wake, H500 ridging will become
reestablished across much of the central/southern US. This will
allow temperatures to climb and rain chances to decrease across
Arkansas and surrounding areas.
