.KEY MESSAGES...
Issued at 1226 AM CDT Thu Jul 17 2025

 - A weak front approaching the area from the north will bring low-
medium chances (20-50%) for storms for parts of northeast Oklahoma
and far northwest Arkansas late tonight and Thursday.

 - Precipitation chances drop off and temperatures increase by the
end of the week as ridging builds in aloft. Hot and dry weather will
likely persist through the weekend and into next week with Heat
Advisories likely.

 - Low chance (<20%) of showers and storms in far southeast Oklahoma
Saturday associated with a possible tropical disturbance.

.SHORT TERM...
(Today)
Issued at 1226 AM CDT Thu Jul 17 2025

Warm and muggy conditions prevail overnight with the forecast area
lying south of an advancing cold front. The front currently
stretches from northern TX Panhandle to central KS with fairly
widespread convection well north of the boundary. This front will
eventually reach near the OK/KS border by early Thursday morning
with some increase in showers and thunderstorms along the boundary
in the 09z-12z time frame.

.LONG TERM...
(Tonight through Wednesday)
Issued at 1226 AM CDT Thu Jul 17 2025

There remains uncertainty regarding overall storm coverage with the
front Thursday morning, though at least scattered precipitation is
expected to eventually spread into far NE OK/NW AR through mid
morning. Coverage may wane into afternoon before potentially more
robust re-developmet in the frontal zone late afternoon and
evening, with potential for a few more organized clusters to produce
strong downburst winds and localized heavy rain.

OUtside of this influence we will see seasonably hot temperatures
with dew points likely in the mid or upper 70s yielding a corridor
of heat index values around 105 from the Arkansas River Valley
toward the Tulsa area, similar to Tuesday. For now will keep areas N
of US 412 out of the advisory as cloud cover may knock a degree or
two off the temperatures.

The front will largely dissipate by Friday and as we go into the
weekend, strong upper ridging will begin to build over the southern
plains, really for the first time all summer. Indications are that
an extended stretch of hot and humid weather will ensue, with
several days of heat headlines likely. A west-moving subtropical
wave moving along the Gulf coast may bring a shower or storm to
extreme SE OK on Saturday, but dry otherwise with above normal
temperatures inching closer to the century mark next week.

.AVIATION...
(12Z TAFS)
Issued at 616 AM CDT Thu Jul 17 2025

Ongoing corridor of showers and storms across SE KS may develop
gradually southeastward through the morning with coverage
decreasing with southward extent. This convection is likely to
wane by early afternoon with VFR conditions prevail area wide. The
remnant outflow boundary from the morning storms will be a focus
for isolated to scattered storms during the late afternoon through
the evening with coverage likely confined to terminals north of
Interstate 40. VFR conditions will prevail away from any storm
influences.
