Strong to severe thunderstorms developed across portions of northeastern Oklahoma during the late afternoon of the 13th, along a pre-existing outflow boundary from earlier organized thunderstorms that moved through Arkansas. The atmosphere became very unstable during the afternoon across the region, and deep layer wind shear was strong.

The episode as NWS TSA wrote it up.
Strong to severe thunderstorms developed across portions of northeastern Oklahoma during the late afternoon of the 13th, along a pre-existing outflow boundary from earlier organized thunderstorms that moved through Arkansas. The atmosphere became very unstable during the afternoon across the region, and deep layer wind shear was strong. This combination resulted in several supercell thunderstorms developing, which produced large hail up to two inches in diameter and damaging wind gusts.
Thunderstorms also developed along a cold front stretching across south central Kansas during the late afternoon and early evening. These thunderstorms moved southeast across northeastern Oklahoma during the evening and organized into a squall line, which produced a number of damaging wind reports.
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 13, 11:43 AM CST, 3 hours 57 minutes earlier. Its key messages:

.SHORT TERM...
(Through tonight )
Issued at 1222 PM CDT Sat Jun 13 2026
Earlier storm activity left a wake of cooler and stable air across
the area, but a surge of warm and humid air is quickly moving north
and scouring out the cooler air. In the immediate short term that
will result in hot and humid conditions developing, with a Heat
Advisory in effect for a portion of eastern Oklahoma this afternoon.
One potentially interesting forecast wrinkle this afternoon will be
a subtle mid level circulation approaching from the west, evident on
visible satellite imagery. CAMs have off and on suggested a few
storms may pop near and north of I-40 this afternoon in response to
this feature, but confidence is low. With that said, if storms did
form, they could become severe given huge instability that is
expected to be in place. Hail would be the dominant threat.
Otherwise, warm advection showers near the OK-KS border also remain
possible into the afternoon.
By late evening and into the overnight hours a strong cold front
will move in from the northwest. Upper level support will be weak
with the trough well removed to the north, but there will be
enough upper level flow and diffluence for storms to develop. Very
large instability will help strong storms to develop near the
front, but line parallel shear will promote quick upscale growth.
Accordingly, a line of storms will form and then move through the
area. Severe weather will be a concern, with strong winds being
the main threat, with a spin up tornado or large hail being
secondary concerns. Very heavy rain is expected with elevated
atmospheric water content across the area. A widespread 1-3
inches is expected with locally higher amounts. Such heavy totals,
along with recent rains, will promote a flood risk along area
rivers and in any location that sees the higher rain rates. A
Flood Watch remains in effect for the areas most likely to be
impacted. Thunderstorms will switch to just showers north of I-40
Sunday morning, with thunderstorms continuing south of the
interstate.
&&
.LONG TERM...
(Tomorrow through Saturday)
Issued at 1222 PM CDT Sat Jun 13 2026
Scattered showers and storms will continue through Sunday, focusing
south of I-40. A relatively cool northerly breeze will keep
temperatures down Sunday and Monday, with highs in the 70s to low
80s and lows in the 60s. Dew points will also briefly drop as
conditions dry out. A few spots may even reach the upper 50s
Monday and Tuesday mornings.
Temperatures will rebound mid week with a temporary resurgence of
upper level ridging, reaching the upper 80s to low 90s. By this
point, a strong trough in the Great Lakes lakes region will help
to strengthen the flow aloft. At the same time, an ejecting
trough out of the southwest will increase low level moisture and
instability. The result will be a resurgence of rain and thunder
chances, continuing into the weekend. Temperatures will cool
slightly to near normal during this stretch.

.AVIATION...
(18Z TAFS)
Issued at 1243 PM CDT Sat Jun 13 2026
Some MVFR cigs are lingering across NW AR terminals, but should
lift through the early afternoon hours. Through the short term,
gusty southerly to southwesterly winds will pick up this afternoon
across the area. A few isolated thunderstorms may also develop
across far E OK into NW AR this afternoon along an outflow
boundary left over from morning convection. An active last half of
the TAF period is expected as storms develop along a cold front
and track southeastward across all terminals through tomorrow
morning. MVFR to IFR cigs and vsbys will be common during
thunderstorm activity. The cold front will bring a shift to
northerly winds Sunday morning along with MVFR cigs filling in
behind the precipitation through the morning hours.

In the short term, dangerous heat will be the story with heat indices of 100-106F for much of the area this afternoon. A couple of storms may develop north of I-40 this afternoon. Even though they will be isolated, severe weather may occur, with large hail as the primary threat. Overnight tonight a cold front will bring a line of storms. For these storms damaging wind and a few isolated tornadoes are the main expected severe hazards. Additionally, very heavy rain will likely result in areas of flash and river flooding, particularly for areas that have seen significant rain this week. Storms will continue through dawn Sunday. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Activation of the Regional Spotter Network Likely. .DAYS TWO THROUGH SEVEN...Sunday through Friday. SUNDAY...Thunderstorm Potential. MONDAY...No Hazards. TUESDAY...Thunderstorm Potential. WEDNESDAY...Thunderstorm Potential...High Wind Potential...Dangerous Heat Potential. THURSDAY...Thunderstorm Potential...High Wind Potential. FRIDAY...Thunderstorm Potential. EXTENDED DISCUSSION... Storm activity will gradually wind down Sunday from north to south. Cooler and drier weather will settle in through Monday. Temperatures will rise into mid week, becoming hot. Breezy southerly winds may help keep the apparent temperature slightly lower but it will still be uncomfortable for many. With the southerly flow, moisture will stream back into the area, with storm chances increasing through the mid to late week period. weather.gov/tulsa contains additional information.
