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 29, 6:16 AM CDT, 1 hour 40 minutes earlier. Its key messages:

  • Lingering showers along with a few thunderstorms are forecast through much of the day today in parts of southeast Missouri and southwest Illinois. Further northwest, dry weather is expected.
  • Temperatures will remain above-normal through the work week, with on/off rain chances. The highest chance for rain will accompany a cold front in the Thursday - Friday timeframe.

.KEY MESSAGES...

- Lingering showers along with a few thunderstorms are forecast through
  much of the day today in parts of southeast Missouri and
  southwest Illinois. Further northwest, dry weather is expected.

- Temperatures will remain above-normal through the work week,
  with on/off rain chances. The highest chance for rain will
  accompany a cold front in the Thursday - Friday timeframe.

&&

.SHORT TERM...  (Through Late Tuesday Afternoon)
Issued at 343 AM CDT Mon Apr 29 2024

(Today)

Widespread showers and embedded thunderstorms continues to push
eastward along with an area of low-level moisture convergence. This
forcing is expected to weaken by 1200 UTC, so the expectation is for
the intensity of the convection and associated rainfall rates to
decrease across southeast Missouri and southwest Illinois as well.
The synoptic cold front still lags to the west a bit, located near a
KCOU>>KIRK axis as of 0700 UTC. This front is expected to wash out
over the next several hours. However, look for showers along with a
few thunderstorms to remain possible most of the day in parts of
southeast Missouri and southwest Illinois as a midlevel shortwave
trough moves across the mid south this afternoon. Nothing strong to
severe is expected, but some brief downpours are possible.

High temperatures today are expected to be similar to yesterday in
most locations, generally in the low to mid 70s. The coolest
locations are forecast to be in parts of northeast Missouri behind
the cold front and in parts of southeast Missouri/southwest Illinois
where clouds will be prevalent into the afternoon hours.

(Tonight - Tuesday)

Decreasing cloudiness is forecast across southeast Missouri and
southwest Illinois this evening, with a clear sky overnight for the
entire area. Light/variable winds along with this clear sky should
allow for temperatures to cool back into the low to mid 50s for
overnight lows. These values are near the 25th percentile of
available model guidance. Given that these lows or below afternoon
crossover temperatures, would think fog may be a concern. This will
especially be true in favored river valleys and where there is
excess surface moisture from recent heavy rainfall.

A quick warmup is expected during the day on Tuesday as low-level
warm air advection strengthens. Highs in the upper 70s to low 80s
are forecast, or about 10 degrees above normal for the last day of
April.

.LONG TERM...  (Tuesday Night through Sunday)
Issued at 343 AM CDT Mon Apr 29 2024

(Tuesday Night - Wednesday Night)

Deterministic models show a midlevel shortwave trough moving quickly
across the Upper Midwest Tuesday night, with a surface low north of
the Twin Cities at 0600 UTC Wednesday. An attendant cold front will
be draped to its south, with this frontal boundary nearing parts of
northeast and central Missouri. This will bring a chance of showers
and thunderstorms to this part of the CWA in the 0600-1200 UTC time
period, with chances rapidly decreasing by Wednesday morning as the
mid/upper level forcing for ascent is becomes even more displaced to
the north and the surface cold front washes out. Mostly dry weather
is forecast on Wednesday, before the chances of showers and
thunderstorms returns to parts of central and northeast Missouri as
well as west-central Illinois Wednesday night. Similar to Tuesday
night, this area gets brushed with mid/upper level ascent southeast
of the track of a midlevel shortwave trough. However, the better
chances of elevated convection reside further to the north where the
warm front should reside and the stronger low-level moisture
convergence.

Temperature wise, the well-above normal values will continue, with
lows in the low 60s each night and highs Wednesday afternoon mostly
in the low 80s.

(Thursday - Friday)

The period with the best chances of showers and thunderstorms (60-
80%) remains Thursday through Friday. The broad time period is due
to uncertainty with the timing of a cold frontal passage across the
region. Ahead of this front, the continuation of well-above normal
temperatures day and night is expected. There is more uncertainty
with Friday's high temperatures across much of the area due to the
differences in frontal timing. Differences between the 25th/75th
percentile of the NBM increase more toward 6-10F degrees in most
locations.

(Friday Night - Sunday)

There is high uncertainty in sensible weather heading into next
weekend. WPC 500-hPa height clusters show vastly different solutions
across the central CONUS, ranging from continued southwest flow
aloft to much cooler weather behind a stronger cold front. Slightly
above normal temperatures with PoPs below climatological normals are
forecast at this time, but confidence is very low.

.AVIATION...  (For the 12z TAFs through 12z Tuesday Morning)
Issued at 607 AM CDT Mon Apr 29 2024

The rain has moved off to the south and east of the metro
terminals, with dry conditions across much of the area through the
remainder of the period. The exception is for some scattered
showers along with a few thunderstorms through this afternoon in
parts of southeast Missouri and southwest Illinois. Ceilings are
variable behind the rain, but generally range from 500 to 2500
feet AGL. This area of stratus will advect out from west to east
through the morning, with metro terminals improving closer to
noon. After the stratus moves out, look for VFR conditions through
this evening. The next concern will be fog late tonight into
Tuesday morning. The best chances are at river valley sites
(KSUS/KJEF/KCPS) and added MVFR visiblities starting between 0700
and 0900 UTC Tuesday. IFR visibilities are possible at these
sites, particularly at KSUS. If confidence increases in fog
potential, worse visibilities than currently forecast may need to
be added.
