Severe Thunderstorm Warning 228, NWS Wichita, KS

Area Forecast Discussion
National Weather Service Wichita KS
658 PM CDT Fri Aug 11 2023

.SHORT TERM...(This evening through Monday night)
Issued at 309 PM CDT Fri Aug 11 2023

Unsettled weather will continue through the weekend within a moist
and unstable airmass with successively stronger perturbations/trofs
aloft moving through as well as low level/surface foci later into
the weekend. For early this evening, residual elevated convection
may fester into south central Kansas with the more robust
activity northeast of the forecast area. Overnight, a modest low
level jet impinging on a reservoir of elevated low level moisture
should promote scattered convection across parts of southern
Kansas with potential for strong storms and heavy downpours. Some
of this activity could linger past 12z Saturday morning closer to
the Oklahoma border. Then better focus for deeper convection is
expected later Saturday afternoon/evening as a shortwave aloft
emanating within the more tropical monsoonal flow over the
southern Rockies will move across Kansas. This will likely first
develop/impact portions of southwest Kansas before moving eastward
with a decent low level jet aiding storm maintenance across south
central/southeast Kansas thru Saturday night. Potential for
strong storms again and heavy rain/localized flooding. We will
close out the weekend with a rather strong upper trof digging
southeastward across the northern Plains/Upper Midwest on Sunday.
This will be accompanied by a strong Summer-time cold front with a
focus for strong to severe convection. This will be followed by a
welcome break from the heat as we tap some cooler/drier Canadian
air which advects across the area for Monday.

.LONG TERM...(Tuesday through Friday)
Issued at 309 PM CDT Fri Aug 11 2023

Temperatures will remain a bit below climo on Tuesday in the wake
of the upper trof moving across the Ohio Valley with a rather
expansive surface high from the western Great Lakes and Midwest to
eastern Kansas. The medium range shows another rather significant
upper trof diving southeast out of southern Canada across the
Upper Midwest and Great Lakes Wednesday through Thursday. Things
look to heat up just ahead of the associated surface cold front on
Wednesday with advection of slightly cooler/more seasonable air
in its wake on Thursday. Precip chances look rather slim with
marginal moisture/instability across the area and better forcing
to the north so will keep the forecast dry next week. For Day 7
and beyond, it looks like a more intense Summer heat will return
again as there appears to be a strong signal for the upper ridge
to build over mid-America.

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 656 PM CDT Fri Aug 11 2023

VFR conditions are expected for the next 24 hours for most
locations. The only exception will be over SE KS, where increasing
mid level moisture advection late this evening, will lead to
increasing chances for SHRA/TSRA over southeast KS after about
08z/Sat.  So will go with a VCTS for the KCNU taf after 08z, with
prevailing SHRA/VCTS after 10z. Could even see some MVFR vsbys in
the heaviest SHRA, so will go with a tempo group for this chance.

There is some uncertainty on how far to the west the convection
associated with the warm advection will get. For now, think most of
the convection will stay to the east of the KICT taf location, so
will not include a VCTS mention just yet.
