Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

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 Wichita, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jan 10, 6:24 AM CST, 3 hours 51 minutes earlier.

Area forecast discussion, Jan 10, 6:24 AM CST, 3 hours 51 minutes before

Area Forecast Discussion
National Weather Service Wichita KS
624 AM CST Fri Jan 10 2020

.SHORT TERM...(Today through Sunday night)
Issued at 349 AM CST Fri Jan 10 2020

This morning:
Challenging forecast with multiple hazards. Very early this
morning, will have transient dense fog along leading edge of rich
moist working north in the greater Wichita metro areas. Elevated
storms during the morning may be strong-severe with good 700MB-
500MB and 0-6km bulk shear offsetting very modest instability.
Main threat is hail, with isolated 60 mph wind gusts also
possible. As precipitation becomes more widespread, severe threat
should wane.

This afternoon-evening:
Focus shifts to winter weather in central KS, where combo of
freezing rain and snow is expected. Snowfall rates could be
impressive for a few hours this afternoon around Russell and
Lincoln counties given deep supercooled layer and good lapse rates
in snow growth zone. As the cold air spills south, anticipate an
expanding area of freezing rain, which could would reach KHUT-KEWK
line roughly around 3 pm, and into the Wichita metro between 5-6
pm. Sounding are especially problematic with very deep supercooled
moisture with a tiny layer just off the surface cold enough to
generate ice. Travel could be especially problematic this evening
across much of central and south central KS as roads begin to
freeze.

The second round of snow is expected later tonight and Saturday,
with most of that in southeast KS. Variations continue in location
of heavier snow, with latest ECMWF a bit slower and south of GFS.

Sunday:
Another fast moving and compact shortwave moves across the area
during the day. Concur with NAM that there should be a chance for
flurries or light snow across central KS and parts of the Flint
Hills. -Howerton

.LONG TERM...(Monday through Thursday)
Issued at 349 AM CST Fri Jan 10 2020

No changes to initialization grids. -Howerton

&&

.AVIATION...(For the 12Z TAFS through 12Z Saturday morning)
Issued at 605 AM CST Fri Jan 10 2020

Timing of winter precipitation and transition from rain to
freezing rain to snow will be the main concerns through the
period. TAFs reflect the going precip forecast. CIGs are expected
to hover around IFR most of the TAF period period though
LIFR/VLIFR will be possible with wintry precipitation this
afternoon/evening, particularly as gusty winds of 25-35kts
accompany falling snow resulting in greatly reduced visibilities
at times. Portions of south central KS will lag the freezing
temperatures until this afternoon scattered rain showers and
thunderstorms will be possible until then. Challenging TAFs today,
frequent updates likely.
