Area Forecast Discussion
National Weather Service Wichita KS
646 AM CDT Thu Apr 27 2017

.SHORT TERM...(Today Through Saturday Night)
Issued at 407 AM CDT Thu Apr 27 2017

Headline:
Flooding potential continues for primarily Southeast KS from late
Fri Night through Sat Night.

Today & Tonight:
The next mid-level short wave is taking on a slight negative tilt as
it pushes SE across the Central Rockies. The approaching short wave
is slowly inducing sfc troffing along the Front Range. With both
becoming more assertive this afternoon, rain and a few thunderstorms
would develop from WY & the Nebraska Panhandle then spread SE toward
Central KS late this afternoon. With the lowest 5,000ft across the
Wrn half of Central KS not moistening until mid-late afternoon have
delayed arrival of the rain to the about NW quarter of KICT Country
til 3-4 PM.

Fri-Sat Night:
Rain & embedded thunderstorms really ramp up as the main upper deck
trof undergoes cyclogenesis as it digs further over the 4-Corners
Region Fri Night. This "main" upper cyclone will follow in the
tracks of its predecessor shortwave, but SLOWLY, as it transitions
into a cut-off low over the NM/TX border Sat Afternoon & Night.
The increasing upper diffluence, enhanced by the approach of
100-110kt upper-deck jet max, will spell trouble for Southeast KS
for it`ll cause a front to pivot around a sfc low centered over
Eastern OK. The warm/moist advection is strong & would translate
into heavy rains across Southeast KS that would be enhanced by
thunderstorms. Flood Watches will likely be required for Southeast
KS Sat & Sat Night.

.LONG TERM...(Sunday Through Wednesday)
Issued at 407 AM CDT Thu Apr 27 2017

The afore-mentioned cut-off begins to lift SLOWLY NE into Central
KS on Sun & with the strengthening upper-deck jet rounding the
base of the upper-deck cyclone the sfc low would surge N/NE toward
Northeast KS & Northwest MO on Sun. The resulting strong "wrap-
around" associated rains would continue Sun & Sun Night. The rains
should gradually taper Mon & Mon Night.

No changes were made to remainder of the forecast period.

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 645 AM CDT Thu Apr 27 2017

VFR conditions are expected for at least the first 12 hours as a
ridge of high pressure slides east into the Missouri Valley. Expect
to see diminishing aviation conditions this evening, as an area of
low pressure currently over the OK panhandle moves east across the
srn plains.  As this low moves east, expect showers and some
embedded thunderstorms to develop across Central KS and areas west
of I-135 early this evening. As the showers move in, cigs will
diminish to MVFR and eventually IFR after midnight. Could also see
some MVFR vsbys in the heavier downpours this evening.
