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 Mar 3, 5:34 AM CST, 4 hours earlier.

Area forecast discussion, Mar 3, 5:34 AM CST, 4 hours before

Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
534 AM CST Fri Mar 3 2023

.SHORT TERM...  (Through Late Saturday Afternoon)
Issued at 419 AM CST Fri Mar 3 2023

Main concern in the short term continues to be the potential for
areal flooding through this morning and winds through this
afternoon.  Have made no changes to going Flood Watch or Wind
Advisory.

Regional radar is showing widespread rain spreading north across the
CWA this morning with surface observations reporting moderate to
heavy rain across the southern and eastern part of the CWA.  Expect
this trend to continue into the morning as surface low currently
over Arkansas is expected to move northeast and quickly deepen as it
moves into southern Illinois by 18Z.  The CWA will lie under strong
ascent caused by a negatively tilted mid-level trough moving through
Missouri and Illinois underneath a coupled upper level jet.  A 60+
knot low level jet will bring in 1-1.5" PWATS which is near max
values for this time of year.  Expect another 1-3" of rainfall with
locally higher amounts in the flood watch this morning.  The
heaviest rates will end this morning with lighter rain ending from
west to east this afternoon as the upper low quicker lifts out.
There may be some light snow mixing with the rain early this morning
over the far northwest part of the CWA, but little if any
accumulation is expected.

Have kept the wind advisory in place as the surface low is expected
to track across southeast Missouri into southern Illinois with tight
pressure gradient across the area.  This will bring up to 50 mph
wind gusts today over eastern Missouri and southwest Illinois.  This
low will move quickly to the northeast by this evening causing the
gusts to decrease after sunset.

Expect quiet weather tonight into Saturday as subsidence sets in
behind the exiting upper low.  The NAM/GFS will move across the area
tonight into early Saturday.

Highs today will be held done by the clouds and the rain.  With
clearing tonight and light winds, lows will be near freezing.  Highs
will warm back above normal on Saturday with sunshine and winds
turning out of the southwest.

Britt

.LONG TERM...  (Saturday Night through Thursday)
Issued at 419 AM CST Fri Mar 3 2023

Dry weather is expected to continue late into the weekend as the
active storm track stays north of the area.  The weather will become
more active by the middle of next week.   The ECMWF/GFS are in
general agreement that a front will move south through the area on
Monday while a upper trough will drop south into the western CONUS.
While there are disagreements on how quickly the western trough will
move east into the Midwest, have enough confidence to keep a chance
of precipitation going from Tuesday into Thursday.

Temperatures will continue to warm into early next week ahead of the
cold front as 850 mb temperatures climb into the 10-15C range on
Monday, but then fall to around 0C by Wednesday.  This is reflected
well by the NBM and GEFS temperature plumes.

.AVIATION...  (For the 12z TAFs through 12z Saturday Morning)
Issued at 519 AM CST Fri Mar 3 2023

Rain, moderate to heavy at times, can be expected at the St. Louis
area terminals through 18Z before the rain will begin to gradually
diminish through the afternoon. Light to moderate rain is also
expected this morning before diminishing early this afternoon at
UIN, COU, and JEF. Predominantly IFR ceilings are expected
through early afternoon at the central Missouri and the St. Louis
area terminals before turning VFR by this evening. MVFR conditions
are expected through this evening. Winds will gust to between
30-40 knots this morning and this afternoon as they back from east
to northwest before decreasing this evening. Conditions will turn
dry and VFR late in the period.
