What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Kansas City, MO wrote its last area forecast discussion before this special weather statement went out at Jun 15, 12:00 AM CDT, 2 hours 10 minutes earlier.

.Discussion...
Issued at 300 PM CDT TUE JUN 14 2016

Water vapor imagery shows a distinct wave that is currently moving
into northwestern Missouri. This can be tracked back to convection
over southwestern KS/northwestern OK from last night. Subsidence
behind the wave will make it very hard to initiate convection. But,
weak surface convergence associated with a modified dryline or
surface trough over eastern KS and NE may still be enough to
initiate convection later this afternoon which may then track into
the area. But confidence is fairly low that this will happen given
the still flat CU field from capping noted on latest aircraft
soundings into Kansas City International. If convection can't
develop during the afternoon, then it may take the effects of the
low level jet to enhance things ahead of the weak surface boundary.
But models are very inconsistent in placing and intensity of the low
level jet. The NAM focuses a portion of the LLJ over eastern KS and
subsequently develops intense convection. The GFS is weaker but
focuses its LLJ farther north with weaker overall convection that
tracks southeastward through the forecast area. Convection allowing
models don't develop anything until the upper level forcing moves
well east of the KC metro area. Given the huge amount of uncertainty
and overall poor confidence that anything will develop, just can't
justify going anything higher than slight chance to low chance PoPs.
So this is what was depicted with this forecast for this evening and
tonight. If storms do develop, there is a decent chance they will
become severe as there is ample instability and marginal shear of
roughly 30 to 35 kts.

Outside of convective chances this evening, the forecast looks very
hot. The combination of heat and humidity may not be in place
Wednesday afternoon. So even though highs look to be in the mid to
upper 90s, heat indices will be in the 100 to 102 range. Thursday
however, is an entirely different animal. Dewpoints in the 70s will
move back into the area with temperatures similar to Wednesday. This
results in heat index values climbing to close to 110. It's likely a
heat advisory will be issued for much of the forecast area to
account for this. But after coordination with neighboring offices,
will hold off until later updates.  This heat will likely then
persist into the weekend. A very strong 600 decameter ridge at 500
mb will spread through the area. This suggests temperatures will be
in the upper 90s, if not approaching the century mark. Have
increased temperatures a bit above the forecast initialization given
this anticipation. With humidity still being oppressive, heat indices
between 105 and 110 are very possible through the weekend. If this
forecast continues to trend this way, heat warnings will need to be
considered, especially for the metro area.

The ridge breaks a little heading into next week as it shifts to the
west. This increases the potential for convection to develop along
the periphery of the ridge, mainly across the northern to
northeastern portions of the forecast area.

.Aviation...(For the 06Z TAFS through 06Z Wednesday Night)
Issued at 1156 PM CDT TUE JUN 14 2016

Small cluster of convection over east central KS is expected to
dissipate as it moves through west central MO early this morning.
Looks like all three Kansas City TAF sites will be affected to
differing degrees with KMKC having the best chance of briefly seeing
MVFR visibilities with a brief downpour. After this convection ends
the rest of the forecast looks benign and VFR with nearly cloudless
skies.
