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 Springfield, MO wrote its last area forecast discussion before this special weather statement went out at Jul 31, 11:34 PM CDT, 1 hour 53 minutes earlier.

Area forecast discussion, Jul 31, 11:34 PM CDT, 1 hour 53 minutes before
Area Forecast Discussion
National Weather Service Springfield MO
1134 PM CDT SUN JUL 31 2016

.SHORT TERM...(This evening through Monday)
Issued at 100 PM CDT Sun Jul 31 2016

Ongoing convection continuing across primarily central into south
central Missouri at this time. This activity is the remnants of an
earlier MCS that is interacting with the northward advancing
surface warm front currently located across the northern CWA. This
activity should continue to progress across the area this
afternoon.

Models are hinting at yet another MCS developing overnight...but a
little further east than last night. Right now...this will
primarily affect central Missouri with wind being the primary
threat.

Otherwise...a strong upper level trough moving through the
Canadian Rockies will push the upper level ridge eastward and
allow the upper high to begin to build eastward. High temperatures
on Monday should be noticably warmer in the upper 80s to lower
90s. Heat index values will be in the upper 90s with a few areas
flirting with 100 degrees or above.

.LONG TERM...(Monday Night through Sunday)
Issued at 100 PM CDT Sun Jul 31 2016

As the upper high shifts eastward and the surface front moves
northward...rain chances will shift primarily to the eastern
CWA...along the eastern periphery of the high.

The primary concern then shifts to those higher heat index
values. Tuesday and Wednesday should be the peak days for heat
indicies. At this time...values look to be in the 100 to 107
range...so will continue to monitor for advisory criteria.

A second short wave moves across southern Canada on Thursday which
will allow a surface front to once again approach central Missouri
by Saturday and increase our rain chances once again.

&&

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1131 PM CDT Sun Jul 31 2016

Elevated convection has developed over the past couple of hours
north of the CWA in a northwest to southeast band. Most of this
activity should remain north of the CWA over the next couple of
hours before eventually drifing into the far northeast CWA.
Activity should remain well to the northeast of the terminal
locations with VFR conditions expected at all 3 forecast points.
Upper level ridge of high pressure should begin to build into the
area from the southwest.
