Area Forecast Discussion
National Weather Service Wichita KS
245 AM CDT Fri Jul 21 2017

.SHORT TERM...(Today through Tuesday night)
Issued at 242 AM CDT Fri Jul 21 2017

A few more days of triple digit heat is expected, before a modest
"cool down" into the 80s- 90s Sunday thru Tuesday. Thinking
readings today will be about a degree higher for many areas due to
compressional warming and slightly drier low- levels ahead of a
front approaching from the northwest. That said, Salina will
probably flirt with their July 21st daily record of 108 degrees
set in 1934. Despite continued triple digit heat, Saturday`s
record highs probably won`t be touched. Will continue the
excessive heat warnings for all areas through Saturday, with late
morning through early evening heat indices from around 103-105
degrees to 107-109 degrees both days.

As has been advertised for several days, a cool front is expected
to ooze south into the Kansas region by Saturday afternoon, in
response to a potent shortwave moving over the northern CONUS.
This front should then stall across the region, before retreating
back north and/or washing out early to mid next week. Despite
relatively weak forcing aloft, the front should serve as a focus
for periodic thunderstorm chances, starting Saturday late
afternoon across central/northern Kansas, with chances gradually
spreading south to include the entire area by Sunday afternoon-
evening. These chances should linger through Tuesday. Not
expecting widespread or organized severe weather or widespread
beneficial rains, although isolated occurrences of severe weather
and very heavy rainfall are possible during mainly the afternoon
and evening hours from Saturday through Tuesday.

.LONG TERM...(Wednesday through Saturday)
Issued at 242 AM CDT Fri Jul 21 2017

Medium range consensus and associated ensembles suggests the
stout mid/upper ridge should attempt to build back in over the
region by Wednesday of next week, which would support a return to
hot and dry weather. However, overall large-scale pattern may
support another cool front moving back into the area by Thursday-
Friday, possibly spelling some relief in the form of thunderstorm
chances and somewhat cooler weather by late week into next
weekend. Still quite a bit of uncertainty, so stay tuned.

Issued at 1121 PM CDT Thu Jul 20 2017

Expecting VFR conditions to persist at all terminals during this
forecast valid period. Marginal low-level wind shear is progged at
1,500 ft agl overnight across central Kansas, with a
southwesterly low-level jet around 35-40 knots, at the top of the

Diurnally gusty south-southwesterly winds will develop by midday
into the afternoon hours, with occasional gusts of 20-25 knots
likely.
