.SHORT TERM...
(Today)
Issued at 252 AM CDT Thu Jul 13 2023

Complex of storms continues to slowly drift south southeastward
early this morning out of southeast Kansas and southwest Missouri
into far northeast Oklahoma and northwest Arkansas. Storms are
expected to persist through at least the early to mid morning
hours, while slowly weakening as they become more removed from
lift associated with a low level jet axis extending across the
region. A few strong to severe storms are possible, mainly
consisting of strong wind gusts, though with steep mid level lapse
rates in place, could not rule out some severe hail with more
discrete convection. Storms should weaken through the mid morning
hours and move east of the forecast area, giving way to another
day of extreme heat across eastern Oklahoma and western Arkansas.
Lingering mid to high level cloud cover left over form morning
convection will at least allow temperatures to be slow to rise
across far eastern Oklahoma and western Arkansas. CLouds will
eventually erode from the west and highs will once again soar into
the mid to upper 90s for most locations, with high humidity once
again leading to widespread heat index values from 105-115. Have
extended the area of the Excessive Heat Warning along the
Arkansas River Valley throughout eastern Oklahoma, but held off
for portions of west central Arkansas due to uncertainty in how
long clouds will hang around this morning. Will leave for the next
shift to monitor trends for possible upgrade this morning.

.LONG TERM...
(Tonight through Wednesday)
Issued at 252 AM CDT Thu Jul 13 2023

Rain chances will increase again this evening and tonight as a
disturbance moves through the mid level northwest flow aloft. The
"juicy" atmosphere in place, consisting of large instability and
stronger mid level flow moving in providing 40-50 knots of
effective shear by the evening, will support some severe
potential. Large hail and a damaging wind threat are likely with
initial storm development, transitioning to more of a wind threat
as storms congeal into another complex during the overnight
hours. Location of this complex will likely be influenced by what
is left over from storms this morning, but guidance at this time
is trending to storms initiating near the Tulsa metro area during
the evening and spreading east through the overnight hours. West
northwest flow aloft will remain in place through the weekend,
with daily shower and storm chances peaking during the evening and
overnight hours. The severe threat will lessen somewhat each day
Friday through Sunday, with the threat pushing further south each
day as well. A weak frontal boundary is progged to slip into the
region Friday night into Saturday and push through the area on
Sunday. where this boundary is located will largely serve as the
focus for greater thunderstorm chances through the weekend. Once
good thing is it will bring some slightly cooler and drier air to
the area in its wake, though afternoon temps will still be toasty
in the lower to mid 90s across much of the area.

Strong upper ridging looks to build back into the region
beginning Tuesday and lasting through much of next week. This
will bring a return to hot and humid conditions, with triple digit
high temperatures returning to the area. With the upper ridge
shifting back overhead, rain chances will be limited through much
of next week as the storm track shifts back north of the area.

.AVIATION...
(06Z TAFS)
Issued at 1244 AM CDT Thu Jul 13 2023

Strong to severe thunderstorms becoming more organized across sern KS
and swrn MO at this time, as low level jet interacts with southward
surging cold pool. Expect nern OK and nwrn AR sites impacted by this
activity between 08-13z as it develops south-southeastward this
morning. Gusty wind and IFR VSBY most likely aviation impacts. Storms
clear out by mid morning, giving way to VFR conditions. Another
chance of thunderstorms exists all sites after 14/00z through the end
of the forecast period and addressed this potential with PROB30
groups for now.
