.SHORT TERM...
(Through Tonight)
Issued at 118 PM CDT Fri May 13 2022

The thunderstorms that have lingered across portions of
east-central Oklahoma through the morning and into the
early afternoon are beginning to show some signs of weakening.
However, additional thunderstorms are possible the remainder of
this afternoon and into this evening in the vicinity of remnant
outflow boundaries across southeast Oklahoma into northwest
Arkansas. The potential for thunderstorms will again ramp
up later this evening as thunderstorms that develop near a frontal
boundary from south-central Kansas into north-central Oklahoma
spread into the area. A few of these storms could become strong
to severe.

&&

.LONG TERM...
(Saturday through Friday)
Issued at 118 PM CDT Fri May 13 2022

After a bit of a lull in the thunderstorm chances on Saturday, the
potential for storms is forecast to increase on Sunday as a mid-level
shortwave moves across the central Plains and pushes a cold front
through the area. Some of these storms could be severe with
large hail and damaging winds the main concern. Dry conditions are
forecast Monday in the wake of the frontal boundary that is forecast to
stall near the Red River. However, the chances of showers and
storms will return to portions of northeast Oklahoma and northwest
Arkansas late Monday night into Tuesday morning as the front moves
back north across the area as a warm front.

The next chance for any showers and storms will come Wednesday night
across northeast Oklahoma and northwest Arkansas as a weak mid-level
shortwave traverses the area.

&&

.AVIATION...
(18Z TAFS)
Issued at 1226 PM CDT Fri May 13 2022

VFR conditions will prevail thru the period outside of storm
activity. Storm coverage uncertain at this time, and confidence
that any terminal will be affected directly is low. Band of high
based showers and a few rumbles of thunder may impact the NW AR
terminals in the near term. Otherwise, expect scattered storms to
develop to the N and W of the region and gradually move SE
tonight. Inserted more conservative prob30 groups in the time
window latest guidance suggests terminals could be affected btwn
00Z and 12Z.
