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 Sioux Falls, SD wrote its last area forecast discussion before this river flood warning went out at Sep 6, 6:14 AM CDT, 2 hours 5 minutes earlier.

Area forecast discussion, Sep 6, 6:14 AM CDT, 2 hours 5 minutes before
Area Forecast Discussion
National Weather Service Sioux Falls SD
614 AM CDT Thu Sep 6 2018

.SHORT TERM...(Today and Tonight)
Issued at 245 AM CDT Thu Sep 6 2018

Surface high pressure moving into northern Minnesota early this
morning will provide mostly sunny skies and seasonably comfortable
temperatures today, with light northeast winds switching around to
the east and southeast through the day.

Subtle wave approaches tonight, but any appreciable moisture will
be tied up by weakening remnants of Gordon drifting slowly through
Arkansas, while our slowly retreating surface high maintains drier
low levels. So while southern parts of the area will see some
increase in mid-high clouds tonight, precipitation threat should
remain south of the area. Northeast parts of the area, under the
greatest influence of the high pressure, could again see nighttime
temperatures dip just below 50, while the increasing clouds in our
south hold readings in the mid 50s through the Missouri Valley.

.LONG TERM...(Friday through Wednesday)
Issued at 245 AM CDT Thu Sep 6 2018

Surface high drifts slowly east across eastern Canada through the
weekend, with an upper ridge shifting through the Upper Midwest
directing the wet remnants of Gordon through the mid-Mississippi
and western Ohio Valleys. Low level flow remains under control of
the Canadian high pressure, keeping humidity levels in the more
comfortable range through the first half of the weekend. Flow
turns a bit more southerly by Sunday, which begins to draw higher
dew points in the 60s northward into the region for the first part
of next week. This will result in gradually warmer overnight lows
as we progress through the weekend, while daytime highs remain a
few degrees shy of normal.

Deeper southerly flow develops as the Canadian high shifts into
the maritime provinces, which should lead to warmer air building
across the region through the middle of next week. Broad trough
slides across the Upper Midwest Monday, followed by weak waves
traversing the region in developing southwest flow aloft through
midweek. While a modest increase in low level moisture is noted
which will increase surface humidity levels, deep moisture return
is less impressive, and thus precipitation chances through the
longer range will remain limited.

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
