What happened

The episode as NWS TSA wrote it up.

Additional thunderstorms developed along and ahead of the cold front during the afternoon and evening hours as it moved into southeastern Oklahoma. The air mass ahead of the front had become very unstable by mid afternoon. This instability, combined with strong wind shear, promoted the development of supercell thunderstorms that produced hail up to golf ball 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 Apr 10, 8:52 PM CST, 1 hour 7 minutes earlier.

952 PM CDT Sun Apr 10 2022

...New SHORT TERM...

.SHORT TERM...
(The rest of tonight)
Issued at 952 PM CDT Sun Apr 10 2022

At mid evening...a cold front stretched from northern Missouri to
far southeast Kansas into northeast Oklahoma...near a Bartlesville
to Pawnee line... and then extended southwest to a surface low in
southwest Oklahoma. North of this boundary...dewpoints were in the
upper 30s to mid 40s in far northeast Oklahoma. While along and
southeast of the front...upper 50s to around 60 deg dewpoints
were common across the rest of eastern Oklahoma and northwest
Arkansas. A mid level impulse marked by increasing mid level
moisture/cloud cover was pushing eastward from western Oklahoma
this evening. The interaction of this feature with lift along the
slowly moving cold front will aid in the anticipated storm
initiation across northern/northeast Oklahoma over the next hour
or so.

Overnight tonight...thunderstorm development is expected near and
to the north of the surface frontal boundary in northeast
Oklahoma...and then spreading into east central Oklahoma and
northwest Arkansas overnight tonight into Monday morning. At the
onset of development...surface based CAPE of 1000j/kg and greater
combined with steep mid-level lapse rates and 500-mb temperatures
around -18C will increase severe potentials with large hail and
damaging wind being the primary threats. If any storm can be more
discrete along the boundary and take advantage of forecast 2-300
m2/s2 effective storm relative helicity and pooling 60 deg
dewpoints...an isolated tornado may be possible. This looks to be
a short window as storms are forecast to become increasingly
elevated behind the front overnight tonight. The greater severe
potential is expected across northeast Oklahoma into far northwest
Arkansas through tonight...with overall severe potentials
weakening late tonight into Monday morning.

The cold front and or surface outflow boundary is forecast to push
into east central Oklahoma and far northwest Arkansas by 12z
Monday. Northerly winds will help temps behind the front to fall
into the 50s...while southerly winds keep temps in the 60s ahead
of the boundary tonight. For the evening update...have adjusted
pops/wx based on the mentioned above and latest trends. Also added
minor adjustments to hourly temp/dewpoint trends based on latest
obs and forecast movement of the boundary. The rest of the
forecast seems to be handling well at this time.

.LONG TERM...
(Tomorrow through Sunday)
Issued at 240 PM CDT Sun Apr 10 2022

The boundary will work its way down into southeast OK and western
AR on Monday. The extended hours of the latest HRRR and the 12Z
HREF suggest some potential for storms along/east of the front
by Monday afternoon/evening. Slowly rising mid level heights
suggest no upper support and thus coverage should remain fairly
isolated. Strong instability suggests severe storms possible with
hail/winds main threat.

Shower and storm chances will increase Tuesday afternoon and
evening across the ArkLaTex and neighboring portions of SE OK and
WC AR in association with a subtropical wave. As previous shift
mentioned, some subsidence in the wake of this wave makes dryline
development farther to the west more uncertain. If a storm goes,
storms would have higher-end severe weather potential. Warm
advection showers and storms may increase in coverage late Tuesday
night in advance of the ejection of a strong upper level storm
system into the Plains with some severe potential.

A cold front will march east across the region Wednesday, earlier
rather than later. Severe storm potential will be greatest over
far eastern OK into western AR ahead of the front during the
midday and early afternoon hours before the threat moves quickly
east of the region.

Shower and storm chances will increase by the Easter weekend,
first in on Friday with a weak wave, and then by Sunday in
association with a stronger cold front. Cooler weather is expected
as we head into the following week with the possibility of more
frost/freeze headlines at some point.

.AVIATION...
(00Z TAFS)
Issued at 641 PM CDT Sun Apr 10 2022

Cold front, currently located near a KOKC/KBVO line will continue
to push slowly southeast overnight. As mid level speed max
approaches from the west, strong storms will likely develop in the
KBVO area, near frontal boundary, by late evening. Lingering
areas of rain with embedded thunderstorms will likely persist,
north of the front, across NE OK, through the overnight hours.
Otherwise, lower IFR/MVFR ceilings will likely develop along/south
of the front, continuing for much of the day with scattered
showers and maybe an isolated thunderstorm or two across NW AR.

much of Eastern Oklahoma.

	RISK...Elevated.
	AREA...West of Highway 75 in Northeast Oklahoma.
	ONSET...Ongoing.

DISCUSSION...
Thunderstorms continue to be forecast to develop across parts of
northeast Oklahoma during the mid to late evening hours this
evening in response to a cold front positioned northwest of
Interstate 44. The thunderstorm threat will shift to the south and
east overnight into east central Oklahoma and northwest Arkansas.
A few strong to severe thunderstorms will be possible, primarily
across northeast Oklahoma and far northwest Arkansas. Large hail
and damaging winds will be the main severe weather threats, as
questionable moisture should limit the overall tornado threat.
Locally heavy rainfall will be possible in parts of northeast
Oklahoma seeing multiple thunderstorms tonight.

Along and south of the frontal boundary late this afternoon, gusty
southerly winds of 20 to 35 mph remained common across the region.
These winds combined with warm temperatures and relative humidity
values below 30 percent northwest of the front were aiding in elevated
fire weather concerns, especially in Osage and Pawnee counties.
Surface winds should continue to weaken overnight along with
decreasing fire weather dangers as humidity values and
precipitation chances increase.

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

.DAYS TWO THROUGH SEVEN...Monday through Saturday.
MONDAY...Thunderstorm Potential...High Wind Potential.
TUESDAY AND WEDNESDAY...Severe Thunderstorm Potential...Very High
						Fire Weather Potential...High Wind Potential.
THURSDAY...No Hazards.
FRIDAY...Thunderstorm Potential...Very High Fire Weather Potential...High
		 Wind Potential.
SATURDAY...Thunderstorm Potential...Very High Fire Weather Potential.

EXTENDED DISCUSSION...
Thunderstorm chances continue Monday across southeast Oklahoma and
northwest Arkansas in proximity to the slow moving cold front.
Severe storms may redevelop Monday afternoon along and east of the
cold front. The unstable airmass will spread northward on Tuesday
and additional storms are likely to develop either in proximity
to a dryline near northeast Oklahoma or in a corridor from
southeast Oklahoma through northwest Arkansas. Conditions will
support severe weather with any storms that do develop Tuesday
afternoon and continue through Tuesday evening. A cold front will
sweep across the region during the day Wednesday and mark another
day of storm chances and severe weather potential. Strong winds
and drier conditions west of the cold front will increase fire
weather concerns.
