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 Aug 10, 3:00 PM CDT, 1 hour 1 minute earlier.

Area forecast discussion, Aug 10, 3:00 PM CDT, 1 hour 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
300 PM CDT Sun Aug 10 2014

.SHORT TERM...(This Evening through Monday)
Issued at 300 PM CDT SUN AUG 10 2014

Warm and humid conditions are in place across the region this
afternoon. Starting to see an uptick in convection during the
past hour, particularly across central Missouri. This is in
response to destabilization due to daytime heating and upper level
energy rotating around an area of low pressure located near Kansas
City. Water vapor imagery and RAP initializations of mid level
vorticity indicate multiple lobes of vorticity emanating from this
upper low. As a result, we should continue to see a gradual
increase in showers and storms across much of the Missouri Ozarks
heading into this evening. The aforementioned upper low and a cold
front moving into the region from the northwest will maintain
scattered showers and storms across the region into much of
tonight. Overnight the better rain chances should begin to shift
to the southeast and east.

High PW air in place (around 1.9" according to the SPC
mesoanalysis page) will result in locally heavy rainfall with this
activity. Deep layer shear remains on the weak side, around 25-30
kt, while both surface based and mixed layer CAPE values are
nearing 3000 J/kg. This should result in a mainly multicell
convective mode with an isolated risk for wet microbursts.

The cold front will exit to the east/southeast on Monday with rain
chances ending during the morning hours.

.LONG TERM...(Monday Night through Sunday)
Issued at 300 PM CDT SUN AUG 10 2014

A nice stretch of weather is expected across the area from Monday
night through Thursday as large area of Canadian surface high
pressure dominates our weather regime. Temperatures will some 7 to
10 degrees below average with comfortable humidity levels.

Temperatures and humidity will rebound back to typical mid-August
values late this week through next weekend as the upper level
pattern flattens a bit. Upper level ridging will attempt to build
into the region from the southwest, meanwhile energy in the
northern stream will threaten to enter from the northwest. Day to
day continuity from individual medium range models have been
lacking (one run wet, the next run dry), however the consensus
suggests that the door will be open to mesoscale convective
systems (MCS) entering from the northwest. As a result, have
continued low end chance PoPs from Friday through the weekend
until finer scale details can be resolved.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon)
Issued at 1202 PM CDT SUN AUG 10 2014

A generally low confidence forecast for the terminals this
afternoon and evening. Thunderstorms are expected to develop west
of JLN early to mid afternoon, and move and develop to the east and
southeast with time. Gusty winds and a drop to IFR can be expected
should a storm move over a terminal. Outside of TSRA, VFR
conditions will prevail. Some light fog and/or stratus development
is then expected late tonight, with conditions dropping at least
to MVFR, with some possibility of IFR. Improving conditions are
then expected tomorrow morning as drier air begins to move into
the region from the north.
