$$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 St. Louis, MO wrote its last area forecast discussion before this river flood warning went out at May 21, 11:39 AM CDT, 1 hour 11 minutes earlier.
Area forecast discussion, May 21, 11:39 AM CDT, 1 hour 11 minutes before
Area Forecast Discussion...Updated
National Weather Service Saint Louis MO
1139 AM CDT Tue May 21 2019
.UPDATE...
Issued at 1139 AM CDT Tue May 21 2019
Line of thunderstorms continues to move northeast this afternoon
over southwest this afternoon. This line has not been severe as it
lies well north of the instability. This will change later in the
day as the RAP has been consistent in moving the warm front north
this afternoon and consequently the instability fields that will
move to along and south of I-70 by late afternoon. Mass fields
from the RAP support what is seen in the CAMS which brings a line
of storms currently over far southwest MO into western AR northeast
into the CWA later this afternoon and this evening. This line
will will intensify as it moves northeast into more instability
later this afternoon and this evening. Deep layer and low layer
shear profiles support a severe QLCS capable of producing damaging
winds a few tornadoes.

.SHORT TERM... (Through Late Tonight)
Issued at 401 AM CDT Tue May 21 2019
A deep upper level trough is making its way through the southwestern
Great Plains this morning resulting in strong lee-side cyclogenesis.
The low level circulation is forecast to move from Oklahoma
northward into Kansas and Nebraska by this afternoon as the
positively tilted trof aloft swings north through the central and
northern Plains. Short range models bring the warm front which is
connected to the surface low up into northeast Missouri and west
central Illinois by 23-00Z this evening. The GFS and RAP are
fairly consistent with the position of the warm front today, and
are very close on the amount of instability that builds up ahead
of the dry line--widespread 1500-2000 J/Kg SBCAPE, and 2500+ near
the triple point between the dry line and the warm front and out
just south of the warm front due to dew point pooling. Models show
60-80kts of 0- 6km and ~50kts of 0-3km bulk shear ahead of the
dry line. Both shear vectors are nearly normal to the front which
strongly favors a linear mode of convection. Indeed...all of the
convection allowing models push a squall line through the area
starting in central and northeast Missouri between 21-22Z,
reaching east central Missouri and southwest Illinois between
00-02Z, and then exiting the area into southeast Illinois between
05-07Z. Damaging wind and isolated tornadoes continue to be the
primary severe weather threat. As if the severe weather threat
wasn't enough, have hoisted a flash flood watch until midnight
tonight. 12 hour radar estimated precipitation shows amounts
between 1-2 inches across parts of central and northeast Missouri.
QPF forecast calls for an additional 1-2 inches across much of
the area as well. With The watch may be overkill across parts of
southeast and south central Illinois where there hasn't been as
much rain, but with P-wats between 1.5-2 inches the storms this
afternoon and tonight should be very efficient rain- producers.
Carney
.LONG TERM... (Wednesday through Monday)
Issued at 401 AM CDT Tue May 21 2019
A southwest flow pattern remains in place for Wednesday behind the
dry line. Consequently, temperatures will likely be several degrees
warmer on Wednesday with highs likely pushing the mid and upper 80s.
It does look dry though, with dew point temperatures in the 50s and
60s for most of the day, so afternoon convection looks unlikely.
However, the persistent low level southwest flow will inevitably
moisten up the atmosphere enough to promote convection. The low
level jet increases to 40-50kts Wednesday night, and the
GFS/NAM/ECMWF collective all show moderate to strong low level
moisture convergence over Missouri and into Illinois overnight with
corresponding QPF output. The NAM and ECMWF keep the majority of
the QPF along and north of I-70 while the GFS is further south. This
is likely due to a buckle in the strengthening upper level ridge
shown in the GFS...which I'm not so sure isn't grid-scale convective
feedback. For the moment I prefer the more northern solutions,
closer to the greatest 850mb baroclinicity.
Models continue to sharpen the upper level ridge over the
Mississippi Valley on Thursday. The GFS forecasts some very high
dew point temperatures on Thursday (>80F)...which look anomalously
high when compared to the ECMWF and NAM. Therefore, I think the
convection advertised by the GFS over central and eastern Missouri
is likely overblown. The EC and NAM look much more reasonable with
precip nearer the Missouri/Iowa border for Thursday...and for
Thursday night and friday for that matter.
The upper ridge axis moves east away from our region on Saturday
allowing a more zonal flow pattern to develop aloft with the upper
high over the Gulf Coast and a persistent low over Canada. The
resulting low level boundary between cool air over the Upper Midwest
and warm moist air over the mid and lower Mississippi Valley is
forecast to stall over northern Missouri or southern Iowa. The
front is forecast to wave north and south Saturday through Monday by
the GFS and ECMWF most likely driven by convection rather than
dynamic forcing. Can't rule out precip along and north of I-70
nearly every period from Saturday through Monday in the vicinity of
the boundary. Temperatures through the period look to be well above
normal...mainly in the 80s.

.AVIATION... (For the 12z TAFs through 12z Wednesday Morning)
Issued at 647 AM CDT Tue May 21 2019
MVFR and some IFR cigs are spread across the area. How far east
and eventually north these low cigs spread is less certain.
However, believe these low cigs will continue north as the warm
front pushes north through the morning and impact KUIN. A few
showers or thunderstorms may arrive at KCOU around Noon today.
These storms are not expected to be severe. Expect a line of
thunderstorms to move east across the region, likely producing
severe or near severe wind gusts as it does. The exception is KUIN
that should remain north of the warm front and therefore may not
receive as high wind gusts. This may change as the event unfolds.
Behind the storms, expect winds to become more southerly, keeping
VFR conditions.
SPECIFICS FOR KSTL/KSUS/KCPS: MVFR cigs remain just SW of
terminals this morning. Model guidance suggests these MVFR cigs
will move north into the area shortly and persist through this
morning. A line of thunderstorms producing, severe or near severe
wind gusts, is expected to move east through the area this
evening. Winds may be a little more light tonight behind the line
of thunderstorms. If so, will need to monitor for fog/stratus
potential, but confidence is too low for now.

Locally heavy rain from last night combined with expected heavy rain from thunderstorms this afternoon and evening may produce dangerous flash flooding. Major river flooding is ongoing along portions of the Illinois River. .DAYS TWO THROUGH SEVEN...Wednesday through Monday. Major river flooding will continue along portions of the Illinois River, and is forecast to reach near major at Saverton on the Mississippi River.
