.DISCUSSION...
Issued at 1044 AM CDT Fri Jul 11 2025

An upper-level ridge across the Bahamas will gradually retrograde
west allowing for a warming trend across the ArkLaTex with
temperatures nearing the triple digits aross portions of north
Louisiana by Tuesday into Wednesday. However, along the western
periphery of the ridge, across mainly southeast Oklahoma and
adjacent counties in Texas and Arkansas, a lingering upper-level
trough will serve as the focus for periods of convection across
these areas from Saturday through Monday night. A mesoscale low
developing within the broader trough axis will linger across
central Oklahoma Saturday night, drifting northeast into Missouri
on Sunday. This feature could be the source for excessive rainfall
across portions of mainly southeast Oklahoma and adjacent
counties in Texas and Arkansas on Saturday night into Sunday.
However, excessive rainfall threat is forecast to diminish by
Sunday afternoon onward as upper-level support migrates east into
the Ohio River Valley. Because of the uncertainty in forecasting
the nuances of mesoscale factors that could contribute to
excessive rainfall, adjustments to the excessive rainfall forecast
can be expected through the weekend.

Otherwise, heat headlines can be expected across portions of the
ArkLaTex from late in the weekend onward as heat index values
approach 105 degrees. /05/

.AVIATION...
(12Z TAFS)
Issued at 629 AM CDT Fri Jul 11 2025

For the 11/12Z TAFs, brief reductions to MVFR/IFR CIGs will be
possible at east Texas terminals near daybreak, rebounding to VFR
into the midmorning. Otherwise, looking for widespread Cu field
development by late morning, settling at 5000 ft during the
afternoon. Scattered afternoon storms may be possible for our
eastern terminals, but confidence is not yet high enough to carry
in prevailing conditions. Southwest winds will increase to
sustained speeds of 5 to 15 kts during the afternoon, with gusts
of up to 20 kts possible, particularly north and west.
