National Weather Service Tulsa OK
238 AM CDT Tue Aug 8 2023

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

.SHORT TERM...
(Today)
Issued at 237 AM CDT Tue Aug 8 2023

Of immediate concern is the ongoing severe weather across east
central and southeast Oklahoma within the mid level moisture axis
and associated with an approaching mid level vort max currently in
southwest to south central Oklahoma. Another batch of strong to
severe storms is located across northwest and north central
Oklahoma in response to another vort max in western Kansas.
Storms across far southeast Oklahoma have exhibited supercell
structure and likely produced large hail despite high freezing
levels. Much like yesterday, these thunderstorms should persist
past sunrise with an overall decrease in coverage toward midday as
the mid level forcing shifts east of the area. Locally heavy
rainfall could become an issue, especially in parts of far
southeast Oklahoma where training could occur. High temperatures
today should be below normal once again, with forecast values
nearer to those offered by the short term blend as opposed to the
NBM.

&&

.LONG TERM...
(Tonight through Monday)
Issued at 237 AM CDT Tue Aug 8 2023

Potential for additional thunderstorm development will exist early
Wednesday morning focused mainly across northeast Oklahoma and
into far northwest Arkansas, but it is less certain than the last
couple of nights have been. This development will result from an
increasing low level jet, with the bulk of the thunderstorms
likely to be north of Oklahoma and Arkansas borders.

Wednesday features the best potential for organized severe
weather across parts of far eastern Oklahoma and into Arkansas, in
association with a robust upper level system set to move through
the Central Plains. Thunderstorms should develop along the cold
front - currently forecast to be near the I-44 corridor - late
afternoon and into the evening, shifting east of the area by
midnight. Regarding the severe weather potential, what happens
tonight will play a major role in that given the possibility of
residual cloud cover impacting instability and also any lingering
boundaries. Large hail, damaging winds and tornadoes look to be a
concern at this point.

A brief dry period should follow the Wednesday system, with
overnight MCS activity increasing once again Thursday night into
early Friday, primarily across northeast Oklahoma and into
northwest Arkansas. This same region will remain at risk for
nightly MCSs through the weekend and into early next week, with
the ridge center remaining south in Texas. Temperatures should
reach above normal levels late this week and continue through the
weekend, with heat advisories or warnings becoming necessary
again. While the chance of seeing triple digit ambient
temperatures doesn't look likely, the rains we've seen of late
could leave us with higher humidity and some nasty heat indices.

&&

.AVIATION...
(06Z TAFS)
Issued at 1217 AM CDT Tue Aug 8 2023

Another round of TSRA will impact the E OK sites early in
the period mainly between 08z-12z with MVFR vsbys in thunder
included in TEMPO groups. TSRA axis may miss the NW AR sites,
but will include a VCTS mention between 11-13z. KFSM will carry the
same VSBY restrictions in two tempo groups between 09z-15z.
Once thunder ends, VFR elements will prevail for the remainder
of the period at all sites.

DISCUSSION...
Another thunderstorm complex is expected to affect parts of
eastern Oklahoma and western Arkansas after midnight tonight,
with the greatest impacts likely south of Highway 412. A few
severe storms will be possible, with large hail being the main
threat. Locally heavy rainfall will accompany the stronger storms,
which may lead to some localized flooding concerns.

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

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Thunderstorm Potential.
WEDNESDAY...Thunderstorm Potential...High Wind Potential...
            Dangerous Heat Potential.

SATURDAY and SUNDAY...Thunderstorm Potential...Dangerous Heat Potential.

EXTENDED DISCUSSION...
Storms may be ongoing Tuesday morning across southeast Oklahoma
and western Arkansas, but will diminish in coverage as the
morning progresses. Another complex of storms is expected to
develop Tuesday night across Kansas and move southeast into
northeast Oklahoma and northwest Arkansas late Tuesday night, with
storms continuing into Wednesday morning. Wind will be the
primary severe threat with this complex.

Additional storms may develop Wednesday afternoon and evening along a
frontal boundary that will be moving through the area. However,
coverage and intensity of Wednesday afternoon and evening storms
will be dependent on the evolution and impacts of the previous
storm complex. Beyond Wednesday, isolated to scattered storm
chances remain possible into the upcoming weekend.
