What happened

The episode as NWS TSA wrote it up.

Thunderstorms developed along a weak surface boundary during the evening of the 9th, and moved across portions of northeastern Oklahoma. The strongest storms produced hail up to quarter size and damaging wind gusts. A slow-moving severe thunderstorm also produced locally heavy rainfall and flash flooding near Catoosa in Rogers County.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tulsa, OK wrote its last area forecast discussion before the first event at Jun 9, 1:31 PM CST, 3 hours 34 minutes earlier.

Area Forecast Discussion

231 PM CDT Fri Jun 9 2023

...New SHORT TERM, LONG TERM...

.SHORT TERM...
(The rest of this afternoon )
Issued at 231 PM CDT Fri Jun 9 2023

Weak sfc boundary/shear axis across far NE OK and NW AR
this afternoon will be the primary focus for scattered
storms into the evening. Isolated storms will remain possible
elsewhere. Strongest activity may pose a marginally severe wind
threat before activity dissipates this evening with the loss of
daytime heating. Additional storms are expected to develop NW of
the area late tonight and form into a complex as it moves E-SE.
These storms may start impacting parts of far NE OK around
sunrise. Severe wind potential will exist with the leading edge of
the complex.

&&

.LONG TERM...
(Tonight through Friday)
Issued at 231 PM CDT Fri Jun 9 2023

The aforementioned complex will continue to move further into E OK
and NW AR tomorrow morning, along with the potential for severe
winds along the leading edge. Some weakening may take place by
late morning, but at a minimum, residual outflow boundaries will
allow for additional convection for the afternoon across SE OK and
WC AR. Severe potential will be higher across far SE OK as any
heating will further destabilize the atmosphere. Most of this
activity should clear the area during the early evening.

An upper level trough diving out of the high plains will push a
cold front towards the area Saturday night. Chances for showers
and storms will increase Saturday night, with the highest chances
across far NE OK and NW AR starting after midnight. The higher
chances will remain across NW AR Sunday as an impulse rotates
through in the W-NW flow aloft. The cold front will clear the area
by late Sunday afternoon or early evening and settle across TX for
the next few days, resulting in cooler temperatures  Monday into
Tuesday. Upper split flow pattern develops next week with a west
to east oriented southern stream over the southern plains. The
frontal boundary to the south looks to lift north as a warm front
around mid week. Several disturbances within faster flow along
with a boundary in the vicinity will result in chances for
isolated to scattered storms for locations along and ahead of the
warm front during that time frame.

.AVIATION...
(18Z TAFS)
Issued at 1233 PM CDT Fri Jun 9 2023

Isolated afternoon storms expected across E OK terminals with
scattered to numerous storms forecast nearer the NW AR terminals.
A gradual decrease in coverage is expected after sunset. Late
tonight additional storms will spread into NE OK and continue
eastward through Saturday morning. Away from immediate storm
impacts VFR conditions are expected to prevail.

	RISK...Elevated.
	AREA...Northwest Arkansas and Northeast Oklahoma.
	ONSET...Ongoing.

HEAVY RAIN.
	RISK...Limited.
 AREA...Northwest Arkansas and Far Northeast Oklahoma.
ONSET...Ongoing.

DISCUSSION...
Scattered thunderstorms will continue through the late afternoon
hours across northeast Oklahoma and northwest Arkansas along a
stalled convergence boundary. A few briefly strong to severe wind
gusts along with hail up to quarter size will continue to be the
primary threat with this activity. Training storms has also lead
to areas of heavy rainfall, mainly across portions of northwest
Arkansas. Localized flooding of urban and low lying areas, along
with small creeks and streams will continue to be a problem into
the early evening. Storms should decrease in coverage after sunset
as instability wanes. A complex of storms will then move into
portions of northeast Oklahoma late tonight with most activity
expected to be sub severe.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Activation of the Regional Spotter Network Likely.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.
SATURDAY...Thunderstorm Potential...Heavy Rain Potential.
SUNDAY...Thunderstorm Potential.
MONDAY...Thunderstorm Potential...Heavy Rain Potential.
TUESDAY...Thunderstorm Potential.
WEDNESDAY...Thunderstorm Potential...Heavy Rain Potential.
THURSDAY...No Hazards.

EXTENDED DISCUSSION...
An area of thunderstorms is likely to be ongoing Saturday
morning with these storms spreading eastward through the day.
A window for severe weather is possible from late morning
through early evening with potential for ongoing storms
to intensify or for new storms to develop. Locations generally
along and south of Interstate 40 have the higher potential for
any severe storms on Saturday.

A cold front will pass on Sunday with additional thunderstorm
chances. The weather pattern becomes more unsettled across
the Southern Plains for next week. One or more days may experience
severe weather potential across portions of eastern Oklahoma
and northwest Arkansas.
