What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Topeka, KS wrote its last area forecast discussion before this river flood warning went out at Oct 7, 2:36 AM CDT, 58 minutes earlier.

Area forecast discussion, Oct 7, 2:36 AM CDT, 58 minutes before

Area Forecast Discussion
National Weather Service Topeka KS
236 AM CDT Sat Oct 7 2017

.SHORT TERM...(Today and tonight)
Issued at 235 AM CDT Sat Oct 7 2017

Early this morning an upper level trough was moving east across
central NE and central KS, and will lift northeast into the Great
Lakes States by Tonight. The surface front was located from
southeast NE, south-southwest to east of MHK, then southward to east
of ICT. The front will slowly shift southeast of the CWA after 12Z.
There may be scattered rainshowers northwest of the front across
northeast and east central KS through the mid morning hours but as
the H5 trough lifts northeast of the plains by this afternoon any
lingering rainshowers should push northeast into MO and IA by the
late morning hours. Isentropic downglide on the back side of the
existing H5 trough will cause skies to clear from west to east
across the CWA during the mid and late morning hours.  West-
northwest surface winds will gradually back to the southwest during
the afternoon hours. Expect mostly sunny skies with highs in the
lower to mid 70s.

Skies will be clear tonight, and with a drier airmass in place,
overnight lows will drop into the lower 50s. A few areas may see
lows in the upper 40s. The moist ground may cause some patchy
shallow ground fog to develop towards sunrise in low-lying area and
along rivers and lakes.

.LONG TERM...(Sunday through Friday)
Issued at 235 AM CDT Sat Oct 7 2017

Broad cyclonic upper level flow will dominate the weather pattern
over the western 2/3rds of the CONUS at the start of the period
on Sunday morning with southerly surface flow in place ahead of a
developing boundary just to the NW of the CWA. The resultant WAA
will push H850 temps up into the +15 to +17 C range over NE Kansas
and surface highs around the 80 degree mark for Sunday. As the
pattern amplifies later in the day, a Front Range low will pull
E/SE towards the Oklahoma panhandle early Monday morning. Model
solutions have come into better agreement in the last 24 hours
with respect to the timing of this event--dragging the attendant
cold front through NE Kansas during the afternoon on Monday.

Strong 300-310K isentropic ascent along and behind the surface
front coupled with good kinematic support will fuel the
development of precip Monday evening. NAM bufr profiles do depict
600-900 J/kg of MUCAPE rooted above this omega max, which would
support thunderstorm development should the instability be
realized. Ample deep shear would also support any organized
updrafts. However, given how the presence of thunderstorms at all
will depend on subtle changes to the strength of the H850 warm
nose, only kept isolated thunder mentioned in the forecast for the
time being.

This inverted trough/cold front will push away from the area on
Tuesday morning with much cooler air filtering into the region.
H850 temps will fall to around +6 C Tuesday afternoon with surface
high temps struggling to get out of the 50s. A gradual warm up
ensues for the middle to latter part of the week with broad
southwesterly flow building downstream of a new longwave trough
over the western CONUS.

&&

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1149 PM CDT Fri Oct 6 2017

MVFR to IFR cigs are expected at the terminals through 13Z then
gradually become VFR by 15Z. SHRA will keep vsbys down in the
mvfr to ifr categories with tsra expected at TOP and FOE through
11Z. Winds shift to the northwest behind the front then gradually
become west then decrease after 19Z. Clear skies are expected
after 18Z.
