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 Wichita, KS wrote its last area forecast discussion before this special weather statement went out at Jul 9, 2:53 AM CDT, 3 hours 20 minutes earlier.

Area forecast discussion, Jul 9, 2:53 AM CDT, 3 hours 20 minutes before

Area Forecast Discussion
National Weather Service Wichita KS
253 AM CDT Thu Jul 9 2020

.SHORT TERM...(Today through Saturday night)
Issued at 250 AM CDT Thu Jul 9 2020

Today-tonight:
MCS continue to race across forecast area at this time. Thinking
combo of outflow and clouds may cut into temperatures, especially
in southeast KS. Several models linger/develop precipitation on
back edge of MCS later this morning, while some fester or
redevelop storms this afternoon in southeast KS. The latter seems
more likely if MCV develops, but less likely if MCS remains
forward propagating. Temperatures in far west are considerably
less certain. Will continue to carry small pops in far southeast
KS late this afternoon mainly due to uncertainty.

Tonight:
Question tonight is whether storms develop as low level jet
overruns as outflow boundary, another MCS rolls in from the
northwest, or both. Have continue small pops through the evening
across the south for the former, but confidence is not
particularly high. Thinking better chance is later, but not
confident about coverage.

Friday-Friday night:
Appears to be second verse with questions about post MCS clouds
and the effect on afternoon temperatures. Went near median of
model spread for highs.

Saturday:
Temperatures should warm a bit on Saturday, with chance for
another nocturnal MCS Saturday night that would clip far northeast edge
of forecast area. -Howerton

.LONG TERM...(Sunday through Wednesday)
Issued at 250 AM CDT Thu Jul 9 2020

Appears that upper ridge will be the predominate player during
this period, with only small chances for nocturnal storms
potentially clipping parts of the area. Temperatures will likely
increase during this period. -Howerton

&&

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1208 AM CDT Thu Jul 9 2020

A line of storms will race southeast across northern Kansas into
eastern Kansas overnight. This will cause outflow winds to surge
southward with gusty north winds. The storms will have the best
chance of affecting SLN and CNU sites. Meanwhile the winds will
gradually switch to the east then southeast behind the departing
storms Thursday morning. VFR conditions are expected in the wake
of the morning storms in southeast Kansas.
