...Updated Aviation Discussion...

.SHORT TERM...(This evening through Wednesday)
Issued at 244 PM CDT Tue Aug 10 2021

An area of mid level showers south of I-70 was developing and
shifting east in the 700 mb confluence zone over central Kansas ,
a notable radar fine line was also spreading south ahead of this
feature and may end up having an impact of where if at all
convection is able to develop this afternoon. The Convective
allowing models, notably the latest HRRR run shows convection as
early as 5 PM around DDc and spreading northeast along the
prefrontal trough (ahead of synoptic surface front near KS/NE
line. Convection wise- deep bulk shear is lack, and even effective
shear is mostly below critical limits for well organized storms.
The trend for effective shear appears increasing however and the
surface based inhibition will still need to be overcome late this
afternoon. All this points to more likely of a later than the models
are showing or even less overall coverage.

The good news is that the peak of hottest temperatures for the next
week or more is right now, as a cooler airmass over the northern
Plains influences western Kansas in the coming days. The cold front
now near the NE/KS line will sag south Tonight and Wednesday.
providing another focus for thunderstorms late in the day on
Wednesday, with a much similar convective environment as Today.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 244 PM CDT Tue Aug 10 2021

Overall a cooling period can be expected with high temperatures
settling back into the mid 80s and low 90s for a general range over
the next 7-10 days.In the short term, still very warm air will
descend off the higher terrain as the surface boundary meanders over
the central plains and strong mid level cyclonic jet stream flow
remains entrenched over southern Canada and the Northern Great
Plains/Great Lakes region. With time this will gradually retrograde
the upper ridge back westward and much less hot but still summer
like temperatures will be seen over western Kansas. With a weak
northwest flow the setup my be one of possibility of diurnal MCS
opportunity, best diagnosed on a day by day basis.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 632 PM CDT Tue Aug 10 2021

Widely scattered thunderstorms at 23z Tuesday near the Hays and
Dodge City areas are expected weaken as they slowly away from
both TAF sites over the next few hours. The gusty outflow winds
will also decrease by 03z Wednesday. For the remainder of the
night into Wednesday afternoon BUFR soundings indicating VFR
conditions with a persistent southeast wind at 10 to 15 knots.
