Area Forecast Discussion
National Weather Service Wichita KS
646 AM CDT Sat Jul 22 2017

.SHORT TERM...(Today through Monday night)
Issued at 305 AM CDT Sat Jul 22 2017

Outflow boundary/bore/gravity wave is currently approaching from
western KS, stemming from earlier thunderstorm activity across the
High Plains. Short-range guidance suggests this feature will
loose steam as it approaches central KS early this morning. It
likely will not be strong/deep enough to erode inhibition for
thunderstorm development early this morning across central KS, or
hamper today`s heat.

Today will be the last HOT day across the region, with
downslope/compressional warming ahead of the approaching cold
front. Widespread triple digit heat is once again expected, so
will continue the excessive heat warning into this evening all
areas. Wichita, Russell and Salina will be flirting with records
highs in the 106-110 degree range. Temperatures will "cool" into
the 90s Sunday-Monday...closer to normal for this time of year.

The approaching cold front from the north will serve as a focus
for isolated to scattered thunderstorms late this afternoon
through tonight across mainly the northern half of KS. Activity
may be aided by a convectively-induced upper disturbance
approaching from the west. These periodic hit-or-miss storm
chances are expected to continue through Monday night or Tuesday,
as the frontal zone stalls out near the KS/OK border Sunday, and
gradually dissipates and retreats back north early in the week.
All-in-all, widespread or organized severe weather appears
unlikely given weak flow aloft and weak forcing, although isolated
occurrences of damaging winds, marginally severe hail and heavy
rain are likely given the expected thermodynamic environment in
vicinity of the frontal zone. Most probable times for storms each
day will be during the afternoon through evening hours.

.LONG TERM...(Tuesday through Friday)
Issued at 305 AM CDT Sat Jul 22 2017

Medium range consensus supports a return to hot temperatures
Tuesday/Wednesday and possibly Thursday as well, as the upper
ridge builds once again across Mid- America. Triple digit heat is
possible. The heat may be short- lived though, as medium range
consensus progresses another cold front into the region late week.
A major cool down appears unlikely, with readings probably
cooling closer to normal in the 90s. This front could also serve
as a focus for periodic hit-or- miss storm chances once again
across the region late week into the weekend.

.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 643 AM CDT Sat Jul 22 2017

Timing of front will be the main challenge. Appears likely that at
least isolated storms will develop late afternoon/early evening
in the vicinity of front. Will go with VCTS at KRSL/KSLN and
possibly as far south as KGBD and KHUT. NAM hinting at MVFR
ceilings behind the front in Central KS, but this is likely
dependent on extent of the storms. -Howerton
