Area Forecast Discussion
National Weather Service Wichita KS
1154 PM CDT Fri Jul 16 2021

.UPDATE...
Issued at 1000 PM CDT Fri Jul 16 2021

Isolated diurnally driven storms have waned across south central KS,
or have shifted southwest into OK. But as the late evening
continues, latest RAP model shows 850-700h moisture transport looks
to gradually increase across south central KS. This will lead to
renewed convection developing across south central KS, late this
evening and overnight. Already seeing signs of this development,
with some isolated showers/storms developing just to the southeast
of KICT.  Think this renewed convection is just the start, with
widely scattered showers and storms expected to keep developing
overnight. The moisture transport isn't as strong as last nights, so
do not think the storms will be as widespread as last night.

.SHORT TERM...(This evening through Monday night)
Issued at 349 PM CDT Fri Jul 16 2021

Main forecast challenge: Thunderstorm chances over the next few
days.

As of late this afternoon, a weak surface front extended from
near the Oklahoma Panhandle across east-central Kansas to central
Missouri. Will maintain a 20-30% chance of thunderstorms in
south-central/southeast Kansas Tonight where modest 925-850 mb
convergence is progged with higher precipitable water of 1.5-1.75
inches. Even though any storms that manage to develop are expected
to be isolated to widely separated in coverage, they would be
high-efficiency rainfall producers. Other convection clusters are
expected to continue developing over the central High Plains
through this evening, with a south-southeastward propagation
overnight. Will maintain a 15-20% probability for thunderstorms
in central KS for late tonight into Saturday morning, although
better chances for storms should be over the High Plains.

Otherwise not much change expected for Saturday-Saturday night with
the front lingering over southern Kansas, with humid conditions and
slight chances for a thunderstorm.

The short-medium range guidance indicates that upper level high
pressure will develop and strengthen over the Rockies Sunday into
Monday, with a mean longwave upper trough in the eastern CONUS. A
shortwave is progged to slide south-southeastward along the
eastern periphery of the Rockies High, across the Central Plains
Sunday into Monday. This shortwave will encounter anomalously high
moisture across the Central Plains and should lead to higher
chances of a thunderstorm complex or two moving through our
forecast area. At this juncture, Sunday night appears to have the
highest storm chances. This wave should also push the front
southward out of Kansas by Monday.

.LONG TERM...(Tuesday through Friday)
Issued at 349 PM CDT Fri Jul 16 2021

Medium range models are in good agreement indicating that the
Rockies upper-level high will tend to persist. After some modest
relief from the heat and humdity early in the week, temperatures
will slowly modify back to around seasonal climatology by
Thursday/Friday. Will maintain dry weather during this period.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1153 PM CDT Fri Jul 16 2021

VFR conditions are expected for the first 6 to 10 hours. Lots of
level moisture continues to linger across the forecast area, with
this tropical airmass expected to linger into Sat as well. So as the
early morning on Sat progresses, expect some MVFR cigs to develop
across much of the forecast from 10-14z/Sat. Surface moisture
remains high as well, which may lead to some MVFR vsbys developing
across portions of central KS for Sat morning as well.

latest RAP model shows 850-700h moisture transport looks to
gradually increase across south central KS overnight. This will lead
to renewed convection continuing to develop across south central KS,
late overnight. Already seeing signs of this development, with some
isolated showers/storms developing just to the southeast of KICT.
Think this renewed convection is just the start, with widely
scattered showers and storms expected to keep developing overnight.
The moisture transport isn't as strong as last nights, so do not
think the storms will be as widespread as last night.
