.NEAR TERM...
(Rest of today and tonight)
Issued at 203 PM CDT Sun Aug 9 2026

Heat and fire weather continue to be the current issues. As of
130 PM, temperatures are up to 105-108 across northwest Oklahoma
with heat index values in triple digits across almost all of the
forecast area. Humidity is down below 20 percent across northwest
Oklahoma with gusty winds creating elevated fire weather
conditions. Still expect some areas of near-critical fire weather
conditions to develop this afternoon across northwestern Oklahoma.
So both the Heat Advisory and Red Flag Warning continue into the
early evening.

Otherwise, mostly clear skies are expected tonight with low
temperatures in the mid to upper 70s.

.SHORT TERM...
(Monday through Tuesday night)
Issued at 203 PM CDT Sun Aug 9 2026

The upper ridge over the southwestern United States pokes a little
more into Oklahoma with heights rising a decameter or two
tomorrow. Typically this would give the expectation of slightly
warmer temperatures, although most of the models suggest we will
have slightly higher dewpoints tomorrow. So there may be a little
more latent heating as opposed to quite as much sensible heating,
so forecast temperatures are near or maybe just slightly lower
than today. Of course with the higher dewpoints and higher
humidity, heat index values will be near or slightly higher than
today, so a heat advisory has been issued for Monday as well.
Tuesday looks pretty similar again and heat headlines will be
likely again on Tuesday.

&&

.LONG TERM...
(Wednesday through Saturday)
Issued at 112 AM CDT Sun Aug 9 2026

Latest model runs are hanging onto the ridge a bit longer with MaxT
interquartile spreads not increasing until Friday (meaning higher
confidence in hot and dry through Thursday). We`re also seeing a
northward trend with the upper systems that do move through late in
the week, reducing the chances for rain and cooler temperatures
across southern parts of the forecast area.
