What forecasters said that day

The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at Sep 5, 2:11 PM CDT, 3 hours 20 minutes earlier.

Area forecast discussion, Sep 5, 2:11 PM CDT, 3 hours 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
211 PM CDT Fri Sep 5 2014

.SHORT TERM...(This Evening through Saturday)

It was a hot and humid day over extreme southeast Kansas and the
Missouri Ozarks. This led to strong instability within this
airmass, with mixed layer capes exceeding 2500 j/kg in most areas.

With a frontal system approaching from the northwest this
afternoon and evening, we think strong to severe storms will be
possible, despite the weak shear present.

The primary hazard with the stronger storms this evening will be
damaging wind gusts in excess of 60 mph. The highest concentration
of storms should occur north of the Interstate 44 corridor, or
essentially along and north of the frontal boundary.

This frontal system will continue to push through southern
Missouri tonight, leaving behind residual showers and
thunderstorms. In fact, this activity could persist over southern
Missouri into the Saturday morning hours. We think by noon
Saturday, all locations will be dry across southern Missouri.

The front will also chill temperatures down to comfortable levels.
Highs on Saturday will only warm into the middle 70s.

.LONG TERM...(Sunday through Friday)

The upper level pattern through most of the Sunday through Friday
time frame will be low amplitude and highly zonal. The summertime
ridge becomes suppressed into southern Texas, allowing for
westerlies to return over southern Missouri.

This pattern shift will lead to additional thunderstorm chances
next work week beginning Tuesday.

Southerly winds commence Monday night bringing back a Gulf airmass
by Tuesday. Models suggest that a short wave trough will approach
and trigger a round of thunderstorms. Storm intensity could depend
on the timing of these storms developing.

This wave will also force a frontal boundary across the region,
and is forecasted to stall out either over southern Missouri or
northern Arkansas.

This feature will become a focus for additional thunderstorm
potential into Wednesday and Thursday. We could experience some
decent rainfall amounts during the Tuesday through Thursday
period.

Have a great weekend and enjoy the cooler weather this weekend !

&&

.AVIATION...(For the 18Z TAFS through 18Z Saturday Afternoon)
Issued at 1244 PM CDT FRI SEP 5 2014

A cold front will push southeast through the area from late this
afternoon into this evening. Scattered thunderstorms are expected
during this time period with showers and perhaps a few
thunderstorms then lingering into late tonight and Saturday
morning. MVFR and brief IFR can be expected beneath any storms.
Weather models then continue to paint a signal for lowering
ceilings for late tonight and Saturday morning. The highest
probability for low-end MVFR and potential IFR will be at
Springfield due to local terrain effects.
