What happened

The episode as NWS TSA wrote it up.

Scattered strong to severe thunderstorms developed near an outflow boundary across northeastern Oklahoma during the early morning hours of the 15th. The strongest thunderstorms produced large hail up to ping pong ball size. Additional strong to severe thunderstorms developed during the afternoon and evening hours, along a southward-moving outflow boundary from earlier thunderstorms that moved through southwestern Missouri and northwestern Arkansas. The atmosphere along and south of this outflow boundary in eastern Oklahoma had become very unstable by the afternoon, and combined with strong deep layer wind shear across the area, an environment supportive of supercells was in place as the storms developed. Several supercells moved across the region, producing large hail up to softball size.

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 May 14, 11:38 PM CST, 1 hour 10 minutes earlier.

.SHORT TERM...
(The rest of tonight)
Issued at 904 PM CDT Sat May 14 2022

An isolated thunderstorm or two will remain possible across northwest
Arkansas this evening given the unstable air-mass in place. Hail to
the size of quarters will be possible in the stronger storms. A few
additional thunderstorms will also be possible across northeast Oklahoma
through the overnight hours.

Taking a quick look at some of the latest CAM guidance for Sunday,
it appears a cluster of storms will likely clip far northeast Oklahoma
and northwest Arkansas during the early afternoon hours with a
hail/damaging wind threat. Additional thunderstorms will likely
develop along the western flank of outflow boundary across portions
of northeast Oklahoma and these storms could be more scattered in
nature. Given the extremely unstable air-mass expected, coupled
with increasing deep layer shear, these storms will be capable of
very large hail and damaging winds through the afternoon hours.
Thunderstorm chances have be updated, including severe thunderstorm
probabilities to reflect current thinking. Update has been sent.

.LONG TERM...
(Sunday through Saturday)
Issued at 100 PM CDT Sat May 14 2022

The greatest potential for severe weather across portions of
eastern Oklahoma and western Arkansas during this forecast
period will take shape Sunday afternoon and evening. A cold
front is poised to move into the moist and unstable airmass
in place across the region Sunday afternoon. This cold front
will be further enhanced by a decaying MCS as it approaches from
the north. As we move into the afternoon hours, thunderstorms
are expected to be ongoing near the front across southeast
Kansas and southern Missouri. These storms are expected to
congeal into a line near the front as it moves into northeast
Oklahoma and northwest Arkansas. These storms will have the
potential to become severe with wind gusts to around 70 mph
the main concern. Large hail will also be a concern especially
early in the event when the cells will be more discrete. The
potential is expected to be rather low with this event. However,
like the hail threat, the tornado potential will be at its peak
when discrete cells are more present. The thunderstorms are expected
to spread south across the area Sunday evening and should
be mostly out of the area by late Sunday night.

The cold front responsible for the Sunday storms is forecast to
stall across north Texas on Monday before returning back north
across the area as a warm front Monday night into Tuesday. Scattered
showers and storms will be possible across portions of northeast
Oklahoma and northwest Arkansas in association with this feature
Monday night into Tuesday morning.

There will be another chance of showers and storms across portions
of the area on Wednesday night as a mid-level shortwave moves
across the region.

The timing of the late week/weekend system is uncertain. However,
more showers and storms are forecast Friday night into
Saturday.

.AVIATION...
(06Z TAFS)
Issued at 1238 AM CDT Sun May 15 2022

A few scattered strong thunderstorms are lingering across
northeast Oklahoma, but should weaken over the next couple of
hours. VFR conditions are mostly expected through the afternoon
with the exception of some fog developing across northwest
Arkansas sites this morning. Thunderstorms are then expected to
develop ahead of a frontal boundary that will move through the
area during the afternoon and evening. The boundary will also bring
a shift to northerly winds around 10 knots.

...SEVERE STORMS EXPECTED ON SUNDAY...

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...Through Tonight.

THUNDERSTORM WITH DANGEROUS LIGHTNING.
	RISK...Limited.
	AREA...Northeast Oklahoma and northwest Arkansas.
    ONSET...Ongoing.

DISCUSSION...

Isolated thunderstorms persist across portions of northwest Arkansas
this evening.  A few of these storms could be strong to marginally
severe with hail to the size of quarters through late evening. A few
additional thunderstorms may develop overnight across northeast
Oklahoma and northwest Arkansas.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY...Severe Thunderstorm Potential.
MONDAY thru WEDNESDAY...Thunderstorm Potential.
THURSDAY and FRIDAY...No Hazards.

EXTENDED DISCUSSION...

An enhanced risk of severe storms is forecast Sunday afternoon
and evening across northeast Oklahoma and northwest Arkansas, in
association with an approaching cold front. Wider swaths of
damaging winds to near 70 mph will be the primary threat as storms
are expected to organize into a complex and drop south through the
region. Initial more cellular development near the Kansas and
Missouri borders will also pose a very large hail and low but non-
zero tornado threat. The severe threat should begin to wane south of
I-40 as instability decreases during the overnight hours.

Storm chances return Monday night into Tuesday morning as a warm
front lifts north into the region. These storms will pose a
limited severe risk. Low storm potential is also forecast Tuesday
night near the Kansas and Missouri borders and again on Wednesday
night across the region, all carrying a limited severe risk.
