.SHORT TERM...(This evening through Sunday night)
Issued at 237 PM CDT Thu Aug 12 2021

Storms have already developed over northeast and western Kansas
along the surface frontal boundary. Additional storms are expected
to develop this afternoon and tonight(mainly over central Kansas).
Wind shear is rather weak today however good instability combined
with inverted-V vertical thermal profile supports mainly damaging
wind potential with high DCAPE. There is some hail potential
especially if a storm can limit mergering with other storms. If the
storm coverage increases a modest cold pool would develop causing
storms to spread southward tonight. Storm redevelopment areas for
Friday/Saturday will be predicated on convective evolution each
day and resultant effects for surface boundary placement. Heading
into Saturday the effective boundary could move further south
into Oklahoma, thus limiting storm chances further north.

.LONG TERM...(Monday through Thursday)
Issued at 237 PM CDT Thu Aug 12 2021

GFS/ECMWF models show a upper level wave dropping southeast across
the region for Monday/Tuesday with a decent precipitation signal.
Daytime highs look to be little bit cooler than normal this period.
Meanwhile models show a more pronounced upper trough moving eastward
from the Rockies across the northern plains for Wednesday into
Thursday. If this signal is maintained it would push a cold front
southward into Kansas which could bring more storm chances to the
area for middle of next week.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 638 PM CDT Thu Aug 12 2021

Main concern through tonight will be thunderstorms across central
and south central Kansas.

Showers and storms are currently near KRSL and KGBD; tsra tempo
groups are reflected in these TAFs through 3Z. Held off on tempo
groups for areas south and east until coverage of thunderstorms
becomes more clear. Amendments to TAFs may be necessary for KSLN,
KHUT, and KICT; however, VFR conditions are expected for the time
being. Also monitoring a boundary sliding southwestward out of
Missouri that would affect KCNU, however storms coverage along the
boundary is low, so VFR conditions are expected to continue
there.

For tomorrow, the boundary triggered showers and storms today will
slosh southward and be the focus for more showers and storms. This
will primarily affect TAF sites in south-central and southeast
Kansas, though we cannot rule out isolated thunderstorms in
central Kansas.
