Area Forecast Discussion
National Weather Service Wichita KS
1157 AM CDT Thu Jul 20 2017

.SHORT TERM...(Today through Saturday Night)
Issued at 313 AM CDT Thu Jul 20 2017

Highlight:
Excessive Heat Warning remains in effect for all areas until 8 PM
Sat.

STRONG upper high that remains sprawled across the southern two
thirds of the U.S. will keep the furnace turned up to dangerous
levels. The Excessive Heat Warning will remain intact through Sat
evening. On Sat an intense cyclone centered over Northern Ontario
will swing a compact mid-upper shortwave from extreme south-
central Canada that will reach Lake Superior late Sat night. This
would send a "lukecold" front almost due south that may still
reach central KS Sat afternoon. The south/southeast progress of
the front will be watched closely as this would certainly have
temperature ramifications Sat afternoon. With the mid-level short-
wave`s greatest kick occurring over the northern plains the front
should decelerate & maybe even stall as it pushes further into
central KS. Would not be surprised if Sat`s highs end up 2-3F
above what CONSALL has assigned across southern KS. With the
nearly east/west oriented front bisecting KS, thunderstorms are
still anticipated Sat night with locally heavy rains possible.

.LONG TERM...(Sunday through Wednesday)
Issued at 313 AM CDT Thu Jul 20 2017

Sunday & Sunday Night:
With the front setting up camp close to the KS/OK border scattered
thunderstorms would be expected across southern KS Sun & Sun night.

Mon-Wed:
The front gradually weakens on Mon but with the boundary expected
to be positioned close to the KS/OK border the furnace would be
turned down about 5 degrees across KICT Country. The "cooldown"
may be short-lived as a rapidly strengthening surface trough
oriented in north/south manner along the Front Range would quickly
allow southerly flow to return to the KS neighborhood. This would
send highs back into the mid 90s. The increasing moisture migrating
from OK may be sufficient to `spark` thunderstorms Tue afternoon.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1156 AM CDT Thu Jul 20 2017

VFR conditions are expected for the next 24 hours.  The only
concern will be an increasing elevated mixed layer for the nighttime
hours, which will lead to some low level wind shear around 2000 ft
agl, for most of the central KS tafs, with winds gusting to 35-40
kts out of the SW.
