Area Forecast Discussion
National Weather Service Wichita KS
1129 PM CDT Thu Sep 21 2017

...Updated for Aviation Discussion...

.SHORT TERM...(This evening through Sunday night)
Issued at 324 PM CDT Thu Sep 21 2017

Unseasonably warm weather will continue thru Saturday, though
welcome changes to much cooler and wetter weather is still in the
offing by early next week for central and southeast Kansas. A
sultry south wind continues to bake the area this afternoon where
the airmass has become very unstable east of the dry-line with
MLCAPE values over 4000 J/KG. While convergence and deep layer
shear is relatively weak, an approaching subtle upper shortwave
trof across the high Plains may be able to overcome weakening
inhibition for isolated late day storms west of the turnpike.
Otherwise, the focus for more organized convection and meaningful
rainfall will remain situated across far western Kansas Friday and
Saturday as the longwave upper trof continues to develop across
the western CONUS. This will keep central and southeast Kansas in
the unseasonably warm southerly low level flow with little if any
focus for meaningful precip. This will begin to change Sunday into
Sunday night, as better lift from the approaching upper trof gets
closer and the associated surface front moves into western
Kansas. This should result in increasing chances for
showers/storms across central Kansas.

.LONG TERM...(Monday through Thursday)
Issued at 324 PM CDT Thu Sep 21 2017

The medium range models show a significant upper trof lifting
bodily northeast from the central Rockies into the northern Plains
on Monday into Monday night, while an additional shortwave dives
south and maintains the mean upper longwave across the Southwest
CONUS into Tuesday. The result for central and southeast Kansas
looks to be the advection of progressively cooler air in the wake
of the cold front with periodic lift along the southward sagging
baroclinic zone supporting numerous showers/storms Monday night
through Tuesday with chances possibly lingering into Wednesday.

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1129 PM CDT Thu Sep 21 2017

Mostly VFR conditions anticipated the next 24 hours. However, may
see patchy MVFR ceilings for a few hours Friday morning generally
east of I-135, but likely remaining above 2000 ft AGL. Otherwise,
stout/gusty south winds will prevail through Friday, as deep low
pressure persists across the High Plains.
