Area Forecast Discussion
National Weather Service Tulsa OK
833 PM CDT Sat Aug 9 2025

...New SHORT TERM...

.KEY MESSAGES...
Issued at 1235 PM CDT Sat Aug 9 2025

 - Dangerous heat will persist through the weekend. Heat
   headlines are in effect for much of the area today and may be
   needed for portions of the area Sunday.

 - Shower and storm chances and relatively cooler temperatures
  return for the first part of next week.

 - Temperatures will rise again during the latter part of next
   week to near average for this time of year.

&&

.SHORT TERM...
(The rest of tonight)
Issued at 830 PM CDT Sat Aug 9 2025

Temperatures will gradually cool off this evening, but remain very
warm overnight, with lows in the 70s to low 80s. Patchy cloud
cover is expected to thin overnight, except across northeast
Oklahoma where a glancing weak shortwave trough will increase
clouds near dawn. Most areas will be dry, but a few isolated
showers or storms may develop near the OK-KS border at that time.

&&

.LONG TERM...
(Tomorrow through Saturday)
Issued at 1235 PM CDT Sat Aug 9 2025

A few showers or storms may be ongoing Sunday morning primarily
across NE OK and points northward. Cloud cover may be enough to
keep temps a few degrees cooler on Sunday which raises uncertainty
regarding additional heat headlines. Forecast heat index values
remain near criteria and an advisory may be needed. Otherwise,
isolated afternoon storms within the higher terrain may develop
Sunday afternoon with a focus toward higher shower and storm
coverage nearing NE OK Sunday evening along a slow moving weak
cold front.

A more notable mid level trough will influence the local region
Sunday night through Tuesday. A composite cold front / convective
outflow boundary will sag slowly southward into the region and
will provide an additional focus. The result will be increasing
shower and storm chances and cooler temperatures. Deepening
moisture and slow and erratic storm motions could lead to locally
heavy rainfall totals.

Weak troughing may remain present across the southern Plains
through mid week which would support daily isolated to scattered
storms, however a quicker return to stronger ridging aloft is also
within the range of possibilities which would be a return to dry
and hot. The forecast will continue the trend of temps returning
to near seasonal normals with low chances of daily terrain favored
precip.

&&

.AVIATION...
(00Z TAFS)
Issued at 554 PM CDT Sat Aug 9 2025

VFR conditions are expected through the period. Mid to high level
clouds will thin overnight before increasing again Sunday,
especially by the afternoon. A few showers and thunderstorms are
possible near KBVO and across northwest AR Sunday afternoon. The
main impacts would be brief heavy rain and gusty erratic winds.
Otherwise, southerly wind of 10-20 kts are expected during the day
and 5-10 kts overnight.
