422 AM CDT Sat May 14 2022

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

.SHORT TERM...
(Today)
Issued at 407 AM CDT Sat May 14 2022

Scattered showers and thunderstorms have flared up in the eastern
part of our forecast area, and isolated convection has entered the
western part of northeast Oklahoma early this morning. The
northeast Oklahoma convection is expected to wane over the next
few hours so will not include pops after 12Z in that area. The
eastern convection may continue for several more hours, with some
redevelopment possible in the same general area late this
afternoon. Afternoon high temperatures will generally range
between 85 and 90 today.

&&

.LONG TERM...
(Tonight through Friday)
Issued at 407 AM CDT Sat May 14 2022

Shower and thunderstorm chances will increase Sunday afternoon and
evening as a cold front sweeps across the area. A few severe
storms are likely, with large hail and damaging winds being the
main threat. The frontal boundary will stall to our south, and
then lift north Monday night and early Tuesday. Elevated
convection may develop north of the advancing warm front late
Monday night and Tuesday morning, mainly affecting parts of
northeast Oklahoma and northwest Arkansas.

Mainly dry and hot weather will then prevail for the rest of the
work week, with temperatures well above the seasonal averages
Tuesday through Friday. An isolated shower or storm will be
possible just about any day, but the chances look too low to
include in the forecast at this time. A stronger storm system
looks to bring a better chance of rain by next weekend, with some
relief from the heat also likely by late next weekend.

&&

.AVIATION...
(06Z TAFS)
Issued at 1223 AM CDT Sat May 14 2022

VFR conditions will prevail through the period with the exception
of some patchy fog possible through early morning at some sites,
particularly the northwest Arkansas sites. A stray storm or two
can also not be ruled out completely, but confidence in affecting
any one terminal is small. winds will remain light and variable
throughout the period.
