WW 373 SEVERE TSTM AR LA OK TX 220850Z - 221600Z
URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 373
NWS Storm Prediction Center Norman OK
350 AM CDT Mon Jun 22 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Western and Central Arkansas
Northern Louisiana
Eastern Oklahoma
North-Central and Northeast Texas
* Effective this Monday morning from 350 AM until 1100 AM CDT.
* Primary threats include...
Scattered damaging winds likely with isolated significant gusts
to 75 mph possible
A tornado or two possible
SUMMARY...A well-organized bowing thunderstorm complex will likely
continue to pose a threat for scattered to numerous damaging winds
as it tracks quickly east-southeastward this morning. Peak gusts may
reach up to 65-75 mph on an isolated basis, and a brief tornado or
two is also possible.
The severe thunderstorm watch area is approximately along and 100
statute miles east and west of a line from 40 miles west of
Shreveport LA to 25 miles northwest of Harrison AR. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU3).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

OTHER WATCH INFORMATION...CONTINUE...WW 372...
AVIATION...A few severe thunderstorms with hail surface and aloft to
1 inch. Extreme turbulence and surface wind gusts to 65 knots. A few
cumulonimbi with maximum tops to 550. Mean storm motion vector
30045.

Areas affected...portions of southeastern Oklahoma...western and
central Arkansas...northwest Louisiana...and northeast Texas
Concerning...Severe Thunderstorm Watch 373...
Valid 221103Z - 221300Z
The severe weather threat for Severe Thunderstorm Watch 373
continues.
SUMMARY...A weakening bowing complex of strong/severe thunderstorms
will continue to produce strong to severe wind gusts through 9 am
CDT.
DISCUSSION...Mosaic radar imagery at 11z depicts a bowing complex of
thunderstorms over far western AR, southeast OK and northeast TX,
moving east at around 45 mph while storms along the southern
periphery sag southeast. This complex, which originated over western
KS Sunday afternoon, has exhibited a gradual weakening trend over
the past two hours as evidenced by a diminishing rear-inflow jet and
lower leading edge reflectivity. Nevertheless, at least some
potential for strong/near severe gusts will continue through 13-14z
given the fast system movement, presence of moderate/strong MLCAPE
in the downstream environment, and a slowly veering low-level jet.
Beyond 13-14z, the severe threat should continue to diminish with
time as the weakening trend continues, in line with short-term
high-res guidance.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
THE CENTRAL HIGH PLAINS....
...SUMMARY...
Scattered severe storms are likely across the central High Plains on
Wednesday with a threat for large to very large hail.
...Synopsis...
Persistent moderate to strong mid-level west-northwesterly mid-level
flow is forecast across the central High Plains on Wednesday. The
surface pattern will be rather nebulous with a weak surface low in
the Midwest and high pressure in its wake across the Plains.
...Central High Plains to the Ozarks...
An ongoing MCS at the beginning of the period may have some severe
risk through the morning hours across Oklahoma/southern Kansas and
into the Ozarks. Expect this MCS to weaken by mid-day as the
low-level jet weakens and it outruns the stronger mid-level flow.
High pressure across the Plains will result in strengthening upslope
flow across the central High Plains. Strong instability is forecast
from northeast New Mexico to southeast Wyoming beneath the moderate
to strong mid-level flow. This environment will support supercells
capable of large to very large hail. For now have kept the threat
mostly confined to the High Plains where the supercell threat is
most likely. The low-level jet response across the Plains is not
that strong Wednesday night and thus, upscale growth into an MCS is
unclear. If a MCS becomes more likely, the Slight Risk would need to
be expanded eastward in later outlooks.

...DISCUSSION...
...D4/Thursday - Central/Northern High Plains...
Upslope flow will strengthen across the central/northern High Plains
on Thursday as a surface low deepens across the southern High
Plains. This, combined with a passing mid-level jet streak and
shortwave trough, should result in scattered storm development
across the High Plains. The most likely corridor will exist from
northern Colorado into eastern Wyoming and far southwestern South
Dakota where the stronger mid-level flow/forcing overspreads the
unstable warm sector.
Beyond Day 4 there will likely be multiple days with eventual severe
weather probabilities given the amplifying trough across the
Northwest and moderate mid-level flow overspreading the northern
Plains where instability will also be quite strong. However, at this
time, there is considerable uncertainty with the timing/location of
each of the mid-level shortwave troughs, and for when the core of
the jet streak associated with the Northwest CONUS low ejects into
the Plains.
Due to these uncertainties, no probabilities have been added beyond
Day 4, but eventual probabilities are anticipated in later outlooks.
