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

.SHORT TERM...
(Today)
Issued at 221 AM CDT Fri Sep 8 2023

Elevated storms are ongoing early this morning across parts of
northeast Oklahoma and far northwest Arkansas, with additional
storms in south central and southeast Kansas. The storms have
developed on the north side of the 850mb front stretched northwest
to southeast across the area. Coverage is likely to expand across
parts of northeast and east central Oklahoma, as well as western
Arkansas toward daybreak as a mid level disturbance moves through
the area. These storms should continue into southeast Oklahoma,
as well, through the morning. Marginally severe hail will
continue to be possible with the strongest storms given the
available CAPE and deep layer shear. Afternoon redevelopment
should be focused across areas along and south of I-40, closer to
the surface front. Severe hail and wind gusts will be a threat
with afternoon development given a forecast increase in deep layer
shear in southeast Oklahoma and continued instability in the
region.

Consideration was given to another Heat Advisory for parts of
southeast Oklahoma this afternoon, with forecast heat index
values approaching 105 in a few areas. However, with increased
cloud cover and potential for storms likely to lead to
temperatures lower than seen yesterday overall, elected to not
issue one this morning.

&&

.LONG TERM...
(Tonight through Thursday)
Issued at 221 AM CDT Fri Sep 8 2023

Thunderstorm potential will continue into Friday night across
mainly southeast Oklahoma, with the severe threat extending into
the evening as well. Drier air filtering in from the northeast
will lead to noticeably lower overnight temperatures especially
across northwest Arkansas and parts of northeast Oklahoma near the
Kansas and Missouri borders. More northerly upper level flow
should lead to fairly pleasant weather for the weekend, with low
humidity, dry conditions and daytime temperatures running near to
just above normal.

Unsettled weather will return for the next work week, as a large
trough over the Northern United States drags a cold front
southward through the Plains early in the week. Widespread
rainfall is likely to accompany the front, with the best chances
coming Monday and into Monday night. A prolonged period of below
normal temperatures will follow the front as well, lasting at
least through the remainder of the week. Trends indicate largely
dry weather for much of the mid to late week period beneath an
expansive surface high pressure area, and as such, have undercut
the NBM POPs a bit most days after Tuesday. Rain chances look to
go up again just beyond this forecast on Friday as another system
moves through.

&&

.AVIATION...
(06Z TAFS)
Issued at 1214 AM CDT Fri Sep 8 2023

Scattered thunderstorms across northeast OK will continue to
develop at times overnight and gradually move southeast towards
northwest AR. The main impacts from these storms will be
lightning, brief heavy rain, small hail, and potentially gusty
winds as well. Storms will also be possible at KMLC but the
probability appears to be lower. Brief CIGS below 10 kft and
potentially as low as 4 kft could develop with any storms but
should quickly lift.

Much of Friday will be dry after the storms clear, with light
winds and clearing skies.
