.UPDATE...
Issued at 1202 AM CDT WED JUL 15 2015

Quick update late this evening to account for latest radar trends. In
collaboration with adjacent offices and National Centers
(WPC/NESDIS)...have elected to hoist a short-fused flash flood watch
across far northern Missouri. Frontal boundary at this hour remains
draped across far western Missouri...and a strengthening
southwesterly low-level jet leading to strong low-level convergence
and theta-e moisture advection along/north of feature. Storms so far
have quickly morphed from a severe threat into a flash flood threat
with upstream radar trends suggesting a developing
training/backbuilding scenario across southeast NE/southern IA/ and
northern Missouri. Looking at latest SPC meso page...PWAT values are
in excess of 2" across these areas...with experimental layered PW
satellite product showing a healthy feed of tropical moisture from
Hurricane Dolores from the eastern Pacific. Furthermore...700-400
DPVA charts from SPC shows a weak amplitude shortwave approaching
this hour from western NE/northwest KS. Coupled with low-level
frontal boundary convergence...overall consensus is flash flood
threat will continue to increase through the early AM.

.DISCUSSION...
Issued at 401 PM CDT WED JUL 15 2015

This evening - Tonight:

The main concern in the short term is the potential for severe
weather this evening in which large hail, damaging winds and a few
tornadoes will be possible mainly west of I-35. However, this
afternoon's showers and thunderstorms may limit that potential.
Models have not been handling the evolving situation well this
afternoon and currently would suggest temperatures in the upper 80s
to mid 90s across western Missouri and eastern Kansas. Temperatures
however remain in the the upper 70s and lower 80s which has limited
instability. That being said, 40-50kts of 0-6KM shear is analyzed
across extreme northwestern Missouri however instability is
significantly lower than models suggest but still a modest 1000-
1500J/Kg of MLCAPE. Further south across southeast Kansas a cu deck
has developed in an area of extreme instability but weak shear.
these will be the two areas to monitor for storm development.
However, it is the northern area that will have the potential for
severe storms. If storms do develop it will occur on the backside of
current storms across north central Kansas where temperatures have
warmed into the lower 90s and dewpoints have risen under WAA. If
these thunderstorms do develop with the good shear over those areas,
it is possible for supercells to develop and move into northwestern
Missouri. It is these storms that would be capable of damaging winds
large hail and possibly a tornado.

Otherwise, later tonight, a wave is expected to eject out the
western Plains and move into the area as a 40-50KT LLJ develops and
noses into southeastern Nebraska/southwest Iowa. An overnight MCS is
expected to develop mainly north of the area however, the southern
periphery f that complex will bring showers and thunderstorms to
northern Missouri.

Tomorrow through Tomorrow night:

Once the overnight MCS clears the area tomorrow morning,
temperatures are expected to warm quickly into the upper 80s to mid
90s. This will lead to strong instability during the day tomorrow.
This will allow for the possibility of thunderstorm development on
any outflow that could trigger storm. Shear is expected to be weak
so storms main be more pulse-like in nature. However, isolated
severe storms may be possible with damaging winds and large hail.
Thursday night a LLJ is again expected to develop and models suggest
the possibility of additional thunderstorm development as an upper
level shortwave traverses the area.

Friday through Saturday:

This period should remain relatively dry as the upper level ridge
builds north into the area and the storm track should shift north of
the area. The best chance for thunderstorm activity would be extreme
northern Missouri. Also, with the ridge building across the area,
highs should warm into the low to perhaps mid 90s.

Sunday - Wednesday:

An upper trough will dig southward into the Plains and Upper Midwest
pushing a cold front into the area. Scattered showers and
thunderstorms will develop along this front during the day. This
front is expected to be slow mover and not exit the area until
Monday morning. Conditions look mainly dry beyond Monday morning as
an upper level ridge looks to build back over the area by midweek.

.AVIATION...(For the 06Z TAFS through 06Z Thursday Night)
Issued at 1247 AM CDT THU JUL 16 2015

Convective activity overnight looks to remain near the Iowa-Missouri
border and is thus not expected to affect the KC terminals through
the morning hours. However, the KSTJ terminal farther north may have
some storms to deal with, so have included VCTS for part of the
morning hours. Later today winds get a little gusty as boundary
layer mixing kicks in with a fleeting chance for more thunderstorm
development Thursday evening, though specific confidence in storms
for Thursday night is rather low.
