Area Forecast Discussion
National Weather Service Wichita KS
652 AM CDT Tue Aug 22 2017

.SHORT TERM...(Today through Thursday night)
Issued at 310 AM CDT Tue Aug 22 2017

A cold front over northwestern Kansas, will continue pushing
southward into southern Kansas this morning, then out of south-
central/southeast Kansas early this afternoon. Scattered
thunderstorms will occur this early morning along the front, with
diminishing chances in the far south later this morning into early
afternoon. Localized pockets of heavy rainfall could still affect
particularly southeast Kansas prior to daybreak near an outflow
boundary, in an area of strong 850 moisture transport, upper-level
diffluent flow, and anomalously high precipitable water near 2
inches.

Noticeably cooler and drier air will filter southward across the
area behind the front, bringing highs slightly below seasonal
averages for today through Thursday.

.LONG TERM...(Friday through Monday)
Issued at 310 AM CDT Tue Aug 22 2017

Medium range models were in decent agreement in depicting several
shortwaves moving out of the Rockies across the central Plains
Friday into this weekend. Southerly return flow and moisture
advection is indicated Thursday night through Friday night,
potentially weakening some over the weekend. The medium range
models are indicating a tropical cyclone (Harvey remnants) redeveloping
over the southwest Gulf of Mexico by Thursday, with this system
intensifying as it tracks northwestward, possibly reaching south
Texas sometime Friday into Friday night. There are the usual model
variations in the track that are likely to fluctuate more between
now and at least Thursday, but the ECMWF,GFS,GEM have the tropical
cyclone making landfall anywhere from South Padre Island to Port
O` Connor.

Scattered showers/thunderstorms should affect portions of
western/central Kansas Thursday night and Friday. Forecast
uncertainty in rain chances increases over the weekend, in large
part due to the tropical system progged to slow down over south
Texas, which could rob moisture return to the Kansas region.
Forecast confidence remains high that afternoon high temperatures
in our forecast area will remain slightly cooler than seasonal
averages.

.AVIATION...(For the 12Z TAFS through 12Z Wednesday morning)
Issued at 652 AM CDT Tue Aug 22 2017

At issuance, numerous (+)TSRA continues to spread SSE ~25KTS
across SE KS. The TSRA should impact KCNU til ~14Z but around that
time IFR cigs (~800FT) will spread S across the terminal. With
widespread post cold frontal stratus continuing to spread S/SW
cigs will be very slow to lift. KCNU may not reach "low-end" MVFR
status til ~16Z & likely won`t realize VFR cigs til ~20Z. Am much
more optimistic across Central KS where cigs should return to VFR
status ~17Z.
