Scattered strong to severe thunderstorms developed into northeastern Oklahoma during the afternoon of the 16th, and became more widespread across the area during the evening and overnight hours. The atmosphere became very unstable during the late afternoon over eastern Oklahoma, and deep layer wind shear increased over the region during the evening with the approach of an upper level disturbance.

The episode as NWS TSA wrote it up.
Scattered strong to severe thunderstorms developed into northeastern Oklahoma during the afternoon of the 16th, and became more widespread across the area during the evening and overnight hours. The atmosphere became very unstable during the late afternoon over eastern Oklahoma, and deep layer wind shear increased over the region during the evening with the approach of an upper level disturbance. This environment supported severe thunderstorms, including some supercells, that produced large hail up to hen egg size and damaging wind gusts.

NWS Tulsa, OK wrote its last area forecast discussion before the first event at Aug 16, 1:34 PM CST, 1 hour 40 minutes earlier.

(Through tonight )
Issued at 210 PM CDT Fri Aug 16 2024
Small cluster of storms keeps chugging along across southern
Kansas this afternoon near a frontal boundary. A very unstable and
weakly capped airmass resides south of the boundary over much of
eastern OK, with DCAPES >1500. Present trends continue to defy CAM
solutions and imply a threat of this cluster eventually moving
into far northeast OK later this afternoon, posing at least a low
threat of damaging wind gusts given the environment south of the
boundary.
Otherwise, dangerously hot and humid conditions persist this
afternoon with heat warnings/advisories continuing through 9 PM.
Still expected re-juivenated convection later this evening north
of the boundary with greatest concentration of storms across NE OK
and NW AR this evening and overnight. Some storm organization is
likely with relatively strong deep layer flow for August, with
damaging wind gusts the primary hazard, but some large hail
potential as well at least initially. Pockets of heavy rainfall
also appear likely, which could lead to localized flooding
potential if heavier rain rates can coincide with locations that
have seen heavier totals as of late.

.LONG TERM...
(Tomorrow through Friday)
Issued at 210 PM CDT Fri Aug 16 2024
Expectation is for convection to be ongoing across mainly NW AR
early Saturday morning. The brunt of organized activity may have
mostly shifted east and south by 12z or shortly thereafter, some
continued rejuvenation of storms remains possible through the
morning within the frontal zone draped across extreme NE OK and NW
AR. The severe threat should be lower at this point, but the
heavy rain threat will continue. Outside of the influence of any
morning convection, dangerously hot and humid conditions are once
again expected Saturday, and additional heat warnings and
advisories have been issued. Notable exception may be the above
mentioned area of NW AR and extreme NE OK where residual cloud
cover may hamper this to some degree. FOr the time being have
kept NW AR out of any headlines, and went with an advisory for the
AR River valley area as confidence is lower in those areas.
Some additional thunderstorm chances continue Late Saturday into
Sunday, primarily across NW AR. Hot weather will continue with
additional headlines likely needed for some areas. Overall the
pattern favors a gradual trend toward not as hot and humid weather
from Monday onward and, whole the forecast does not explicitly
mention any storm chances next week, we do remain on the periphery
of upper ridge with a NNW flow aloft, raising some uncertainty in
keeping a dry forecast. IN any case we will get a break from the
excessive heat, first across NW AR/NE OK, then most everywhere by
mid-week.

(18Z TAFS)
Issued at 1204 PM CDT Fri Aug 16 2024
VFR conditions should prevail through the period, with any
category reductions to occur in thunderstorms. MLC is the only
site with thunderstorm chances low enough to keep out of the TAF,
with PROB30s included late this evening into early Saturday
morning at the remaining terminals. Confidence is highest at the
far NW AR sites and will depict IFR conditions in the PROB30, as
well as potential for strong wind gusts. A TEMPO was strongly
considered at these sites. Conditions should improve through the
morning hours.

AREA...Northeast Oklahoma and Northwest Arkansas. ONSET...This Evening. DANGEROUS HEAT. RISK...Significant. AREA...Eastern Oklahoma and Northwest and West Central Arkansas. ONSET...Ongoing. DISCUSSION... Dangerous heat and humidity are ongoing early this afternoon in eastern Oklahoma and northwest and west central Arkansas, with heat index values from 105 to 115 remaining likely into early evening. A low chance of isolated afternoon thunderstorms exists for areas along the Kansas border, which would pose a threat for damaging wind and large hail if they do occur. Greater potential for evening and overnight thunderstorms exists in northeast Oklahoma and northwest Arkansas, with conditions continuing to favor strong wind gusts, hail and locally heavy rain and flooding potential. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Local Spotter Activation May Be Needed. .DAYS TWO THROUGH SEVEN...Saturday through Thursday. SATURDAY AND SUNDAY...Thunderstorm Potential...Dangerous Heat Potential. MONDAY THROUGH THURSDAY...No Hazards. EXTENDED DISCUSSION... Tonight's thunderstorms may linger past daybreak Saturday morning across northwest Arkansas, although the severe weather potential should have waned. Additional thunderstorm development is expected into Sunday. Dangerous heat will persist through the weekend. Relatively cooler temperatures are expected next week as the upper ridge shifts west away from the region and a cold front moves through the area this weekend. weather.gov/tulsa contains additional information.
