(Rest of today and tonight)
Issued at 111 PM CDT Sun Aug 17 2025
The showers and thunderstorms persist across north central Texas
and south central Oklahoma this afternoon and are expected to
continue this afternoon and perhaps into early this evening.
Meanwhile an area of cumulus has been developing west of Childress
that may be the beginning of new development that some models show
developing this afternoon and spreading into western Oklahoma.
Right now it looks like the southern storms will primarily be
diurnal while a weak shortwave may be enough to support western
convection into the evening. Coverage may not be widespread and
POPs for any particular area is still relatively low.

.SHORT TERM...
(Monday through Tuesday night)
Issued at 111 PM CDT Sun Aug 17 2025
Stop me if you've heard this one before, but the heat continues.
Advisory-level heat index values are again expected...primarily
in the southeast with the highest humidity, the post-harvest wheat
belt of north central Oklahoma, and the urban heat island of
Oklahoma City. So another heat advisory has been issued for
tomorrow afternoon, and again for the same locations where we have
had advisories the last couple of days. And again, diurnal
thunderstorms will be possible. Tuesday looks similar as well.
&&
.LONG TERM...
(Wednesday through Saturday)
Issued at 1228 AM CDT Sun Aug 17 2025
A week cold front will move through the area Wednesday, providing
a cool down through the end of the week and into the weekend.
Rain chances will increase Wednesday along this boundary as it
moves through. Rain chances will shift southward through the day,
and will be possible again Thursday across the southern third of
the area. Upper 80s to low 90s are expected through the end of
week, with lows in the upper 60s to low 70s by the end of the
week.

VFR/low VFR ceilings this TAF period. There are low chances for scattered
showers/storms across this afternoon into Monday morning. This is
not mentioned in most of the TAFs due to the low chances,
scattered nature, and low coverage expected. Southerly winds will
continue this TAF period as well although shifting winds will be
possible for a brief time near any of the storms.
