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 Apr 2, 4:08 AM CDT, 42 minutes earlier. Its key messages:

  • Thunderstorms will exit the area this morning. Additional thunderstorm development is possible during the late morning and early afternoon, but the storms are not expected to be severe.
  • Colder then normal temperatures are expected for the rest of the week. Temperatures warm back to near normal for the coming weekend.
Area forecast discussion, Apr 2, 4:08 AM CDT, 42 minutes before
Area Forecast Discussion
National Weather Service Saint Louis MO
408 AM CDT Tue Apr 2 2024

.KEY MESSAGES...

- Thunderstorms will exit the area this morning. Additional
  thunderstorm development is possible during the late morning and
  early afternoon, but the storms are not expected to be severe.

- Colder then normal temperatures are expected for the rest of the
  week. Temperatures warm back to near normal for the coming
  weekend.

&&

.SHORT TERM...  (Through Late This Afternoon)
Issued at 339 AM CDT Tue Apr 2 2024

Primary concerns this morning center around convection exiting the
forecast area, and redevelopment during the late morning/early
afternoon.  A strong trough of low pressure aloft extends from south
central Canada southwest all the way through the Desert Southwest
into the eastern Pacific Ocean off Baja California.  This trough is
forcing cyclogenesis over the Lower-Missouri/Mid-Mississippi Valleys
this morning, and the resulting surface low will drag a cold front
thorough our forecast area today.  Colder drier air will rush in
behind the front during the afternoon and evening which will finally
bring precipitation to an end.

In the very short term, any remaining showers and thunderstorms are
unlikely to be severe early this morning.  The atmosphere has been
scrubbed pretty pretty well of instability.  Latest RAP forecasts
show CAPE values at or below 500 J/Kg at this time, and it doesn't
start to recover until mid to late morning.  RAP does attempt to
recover some instability by early afternoon, and there could be
additional thunderstorm development until the front moves through.
Current thinking is that any storms that do develop will be on
their way out of the forecast area very quickly before they can
become severe.

Carney

&&

.LONG TERM...  (Tonight through Monday)
Issued at 339 AM CDT Tue Apr 2 2024

Briefly for the long term: below normal temperatures are expected
for the remainder of the week. The trough closes off into a deep
low over the Midwest tonight and it spends the rest of the week
meandering eastward and finally off the Atlantic Coast this
weekend. Persistent northwest flow and cold advection will keep
temps well below normal. Light freezes with temps near or just
below 32 look likely for parts of the area for Thursday, Friday,
and Saturday mornings. Additionally, several vorticity maxima will
rotate around the low producing lift and precipitation tonight
through Wednesday. Looks like temperatures should be cold enough
for a rain/snow mix at times during this period, but no
accumulation is expected.

Carney

&&

.AVIATION...  (For the 00z TAFs through 00z Tuesday Evening)
Issued at 636 PM CDT Mon Apr 1 2024

Severe thunderstorms will continue to threaten the central
Missouri and St. Louis metropolitan area through the early morning
on Tuesday. Large hail and strong winds would accompany any storms
that can form. KUIN will likely not see strong storms, but weaker
ones will still threaten the terminal.

VFR conditions will degrade to MVFR and IFR as the night
progresses, and a cold front will approach from the west to swing
winds more westerly as well Tuesday afternoon and evening. Low
CIGs will likely persist after the front passes through with
cyclonic flow aloft staying put. Rain chances don't definitively
end until beyond the valid TAF period.
