Area Forecast Discussion
National Weather Service Hastings NE
338 PM CDT WED JUL 20 2016

.SHORT TERM...(This evening through Friday night)
Issued at 338 PM CDT Wed Jul 20 2016

The main concern in the short term and the mid-term is the extreme
heat. Highs in the upper 90s and low 100s will continue through at
least Friday with heat index values during the afternoon between
105-110. Earlier today the Excessive Heat Warning was expanded to
include the entire area across south central Nebraska and north
central Kansas. Highs in the upper 90s and low 100s with
relatively high dewpoint values in the upper 60s and low 70s
yields heat index values around 105 or higher during the peak
heating each afternoon through Friday. Did not see any reason to
not include the whole area as it will be similar across the board.

There will be multiple chances for showers and thunderstorms
Thursday night through Friday night across the area. The chances
are relatively small, but being closer to the peak of the ridge,
each weak disturbance moving around the ridge could spark a few
showers and thunderstorms moving in off the high plains.

.LONG TERM...(Saturday through Wednesday)
Issued at 338 PM CDT Wed Jul 20 2016

The ridge flattens out as the weekend approaches and a front is
expected to slide slowly east across Nebraska. The temperature on
Saturday depends on how quickly this front slides east and if any
precipitation develops along it. Currently still have highs in the
upper 90s with a few low 100s in Kansas, and heat index values in
the low 100s. However, due to the uncertainty felt it was best to
not expand the excessive heat warning...basically watching it
until confidence increases for it`s warranted or not.

As the ridge breaks down and zonal flow dominates the forecast
there are small chances for showers and thunderstorms through most
periods. A more significant wave will approach the area Tuesday
into Wednesday which has a better chance of bringing more widespread
rain. With the ridge breaking and the chances for precipitation,
temperatures look to moderate back into the upper 80s and low 90s
for Sunday through Wednesday.


.AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Thursday afternoon)
Issued at 1232 PM CDT Wed Jul 20 2016

The main aviation forecast concern is low level winds shear
tonight. VFR conditions outside of this period. Winds will be
southerly and skies will be mostly clear. Tonight a strong low
level jet will cause low level wind shear at both terminals. This
will decrease towards morning at both terminals with VFR expected
