.SHORT TERM...(Today and Tonight)
Issued at 245 AM CDT WED JUL 29 2015

Outflow dominant area of convection over northern MO/Northeast KS
is propagating se-ese. Most high res models continue to weaken
this area in the near term as it moves farther south underneath
mid level ridging. Will continue to carry low pops over the northern
cwfa with the outflow boundary pushing into the area early today.

For later today guidance is a mixed bag as the modest sfc
convergence with the true sfc front moves into the region this
afternoon. Winds veer quite a bit over southern MO today prior
to the frontal passage which limits convergence. SREF and global
models redevelop at least some modest qpf this afternoon, while
high res models are nil or close to it. Weakly capped moderate
mean layer instability will exist, so it`s just a question of
whether overall weak forcing mechanisms will be able to produce
some updrafts. A blend of guidance yields slight to low chance
pops with overall better chances over the eastern-southeastern
cwfa this afternoon. Doesn`t look long lived or widespread.

Heat index values will be highest over the southeast cwfa this
afternoon and will continue the heat headlines as is pending any
further collaboration with surrounding offices.

.LONG TERM...(Thursday through Tuesday)
Issued at 245 AM CDT WED JUL 29 2015

It finally looks like we will see some overall relief from the
humidity for a period of time.

The sfc front shifts south of the area as sfc high pressure moves
into KS/MO Thursday and the upper level ridge is suppressed back
to the south and southwest. Some elevated late nighttime
convection might spill into the far sw cwfa for early Thursday,
but will go for mostly a dry forecast.

The upper ridge will amplify over the western CONUS late in the week
and this weekend leaving us in a northwest flow pattern without
any major signals for significant shortwaves and precip as weak
sfc high pressure remains nearby. Differences in timing exist
with the next shortwave moving southeast through the region early
next week. We should see dew points creep up a bit late in the
extended period with only very modest pops/rain chances. Better
chances for rain may hold off until just after this forecast


.AVIATION...(For the 06Z TAFS through 06Z Wednesday Night)
Issued at 1141 PM CDT TUE JUL 28 2015

VFR conditions are expected to prevail through Wednesday evening
with some increasing high clouds. Winds will shift around to the
north behind a passing cold front on Wednesday. At this time, it
appears that most thunderstorm activity will remain north of the


MO...EXCESSIVE HEAT WARNING until 9 PM CDT this evening FOR MOZ082-
