.SHORT TERM...(This evening through Friday night)
Issued at 241 PM CDT Wed Aug 10 2016

Upper circulation that was over the TX Panhandle yesterday has
weakened and is now making its way across central KS. Iso-Sct
storms developed this afternoon just head of this feature in an
airmass with around 3,000J/kg of CAPE and PW's greater than 2".
Wet microburst winds and high rainfall rates/flooding will be the
main threats. Some of this activity should continue into at least
the early evening hours east of I-135.

Did go ahead and run with another heat advisory for Thu and
pulled it back west another row of counties. Confidence is high
that maxes Thu will be the hottest of this forecast package as
850mb temps spike just ahead of the cold front passage.

Another weak upper impulse is expected to lift out of se NM and
across central KS on Thu afternoon/evening. In addition, the cold
front will start its southward push across the central/southern
Plains Thu evening through Fri. By 12z Fri the front should be
along the KS Turnpike and south of the forecast area by 00z Sat.
Should see showers and storms first develop late Thu afternoon
along/north of I-70 with storms pushing south and east Thu night
into Fri. Areal coverage should be aided by central/eastern KS
remaining in the right entrance region of an upper jet. Cant' rule
out some low end severe Thu night through Fri as shear increases,
but with PW's still hovering around or just over 2", high rainfall
rates an flooding may end up being the main threat. With the front
moving south at a pretty good clip, short duration flooding looks
more likely than a 2-3 day event.

By Fri night, the main storm/flooding threat will shift into far
southeast KS/eastern Ok/southern MO which is where the front will
be situated. Although, still can't rule out sct convection
further north with right entrance region hovering over the area.

.LONG TERM...(Saturday through Wednesday)
Issued at 241 PM CDT Wed Aug 10 2016

ECMWF is a bit more agressive in pushing the front south compared
to the GFS. If the GFS is correct, SE KS will continue to see
precip Sat with the ECMWF keeping area dry. Will hold onto some
pops over SE KS Sat and Sat night to account for the model
differences. However, higher confidence for heavy rain stays south
into OK and AR. Still running with below normal temps through the
weekend into the start of the work week with most sites topping
out in the mid to upper 80s.

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1222 PM CDT Wed Aug 10 2016

VFR CONDITIONS WILL PREVAIL THROUGH THE PERIOD. A SLIGHT CHANCE
FOR VCTS IS POSSIBLE AT KCNU...BUT NOT ENOUGH OF A CHANCE TO
WARRANT MENTION IN THE FORECAST.
