Area Forecast Discussion
National Weather Service Wichita KS
317 AM CDT Mon Jul 17 2017

.SHORT TERM...(Today through Wednesday night)
Issued at 316 AM CDT Mon Jul 17 2017

Upper ridging remains over the Plains into the mid and upper
Mississippi Valley. The upper impulse that has been responsible
for showers and storms the last few days over western KS/eastern
CO is now lifting over NW KS.

This upper wave will continue lifting northeast and is expected to
track over west-central Nebraska today and into western IA
tonight. While the bulk of the showers and storms will stay north
of the forecast area this evening, can`t rule out a few stray
showers or storms along the upper trough for areas along and north
of I-70. Large MCS is expected over the northern/central Plains
Tue night as shortwave energy passes over the area. There are a
couple model solutions that try and develop sct storms into
northeast and north central KS. Confidence in this occurring is
not very high, so will not get too aggressive with pops this far
south at this time.

Slow warming trend will continue into Wed, with heat indices
starting to top 100 on Tue over mainly central KS and area wide on
Wed. Not out of the question a heat headline maybe needed for Wed
for mainly eastern sections of our forecast area, but it will
depend on how much dewpoints mix out each afternoon.

.LONG TERM...(Thursday through Sunday)
Issued at 316 AM CDT Mon Jul 17 2017

Well above normal temps will continue for Thu and Fri with heat
indices in the 100 to 105 degree range area wide. Highest heat
indices will be for the east and northeast portions of the
forecast area where dewpoints will likely not mix out as much.

There is good model agreement that shortwave energy will track
across southern Saskatchewan and Manitoba Fri night into Sat and
will help break down the upper ridge. This will also allow some
moonsonal moisture from the southwest CONUS to work into the
Plains. The ECMWF is more agressive diving the shortwave energy
further south compared to the GFS which would lead to a slight
cool down for Sun into Mon. Meanwhile, the GFS is more agressive
in spilling mid level moonsonal moisture into the Plains. Needless
to say, confidence in the weekend forecast is very low at this
time.
