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 5, 2:52 PM CDT, 5 minutes earlier.

Area forecast discussion, May 5, 2:52 PM CDT, 5 minutes before

Area Forecast Discussion
National Weather Service Saint Louis MO
252 PM CDT Thu May 5 2022

.SHORT TERM...  (Through Late Friday Night)
Issued at 242 PM CDT Thu May 5 2022

This morning's soaking rain has moved out of the area, though a
stacked cyclone remains to just to the west of the region. This
system will continue to drift east, bringing another round of
precipitation into central/southern MO as the center of the low
moves into the region late this evening. On and off showers will
then spread across the region overnight, lingering until the low
departs the region tomorrow afternoon. We may see a few thunderstorms
embedded within the showers, mainly south of the I-70 corridor,
though very limited instability will keep these few a far between.
The lack of deep convection should keep additional precip totals
in check, with amounts generally expected to be less than 1".
However, the HREF probability matched mean QPF, which preserves
some of the higher precip bullseyes in the individual CAMS, does
show additional QPF exceeding 1" over a small portion of our
forecast area. Should this heavier precipitation fall over areas
that have already received 2-3", generally between the Missouri
and Meramec Rivers, it may exacerbate any lingering flooding
issues.

Continued showers, overcast skies, and generally
northerly winds will keep temperatures quite cool tomorrow.

BSH

.LONG TERM...  (Saturday through Next Thursday)
Issued at 242 PM CDT Thu May 5 2022

By Saturday morning, the cyclone responsible for today's wet weather
will be pushing through the Mid-Atlantic states, which will draw
much of the moisture responsible for Friday's rain and clouds out of
the area. Meanwhile a broad trough will be digging into the Pacific
Northwest, deepening a surface trough over the High Plains as it
pushes eastward through the day. Downstream of the trough, deep
ridging will amplify over the Midwest, with the ridge axis pushing
east of the Mississippi sometime on Saturday. As the ridge shifts
east, winds over the mid-Mississippi River Valley will shift from
the north/east to the south by Saturday afternoon or evening. The
initially cool winds on Saturday, along with any lingering clouds
associated with the departing low, will result in a chilly start
to the day. Temperatures will then climb rapidly and reach to
just below normal by the afternoon.

Southerly flow will intensify on Saturday night and Sunday as the
PacNW trough pushes further inland and the surface trough/low
deepens over the Plains. Increasing southerly winds draw even warmer
air into the region, with both the NAEFS and ECMWF ensemble means
topping the 90th climatological percentile across much of the
forecast area by Sunday afternoon. The southerly winds will also
advect deeper moisture into the region, though there is some
uncertainty as to whether this increasing moisture will be
sufficient to result in precipitation. Roughly 30% of ensemble
members are spitting out measurable precipitation somewhere in our
forecast area, with the majority of those members residing in the
GEFS system. If we do see any precip, the odds of seeing any
impactful showers or thunderstorms appears quite low; virtually
none of the ensemble members show even 0.01" of QPF on Sunday,
and the probability for any more than 500 J/kg of MUCAPE is quite
low.

The upper level flow will further amplify as we move into the work
week with the ridge expanding across the eastern half of CONUS and a
reinforcing shortwave deepening the trough over the western CONUS.
This will result in deep southwesterly flow over the central portion
of the country and will continue to advect even warmer temperatures
into the region. On Monday, Tuesday, and Wednesday, both the ECMWF
and NAEFS ensemble mean 850 temps are at or near climatological
maximums area-wide. With rising heights aloft largely keeping a lid
on precipitation chances and limiting cloud coverage, temperatures
should easily push into the upper 80s and will approach record
values in most locations. Things may get slightly cooler on
Thursday as the upper ridge begins to break down, but considerable
differences remain in the guidance this far out. Nevertheless, we
can say the the well above normal temperatures will continue into
the end of next week.

.AVIATION...  (For the 18z TAFs through 18z Friday Afternoon)
Issued at 1234 PM CDT Thu May 5 2022

Showers are exiting the area to the east, leaving a widespread
stratus deck in their wake. This stratus will remain in place
through the duration of the TAF period, with cigs lingering near
or below 1000 ft. Model guidance is in strong consensus keeping
IFR cigs in place throughout the TAF period, and the last several
hours of observations support the guidance in most locations. I do
think we'll see the individual terminals occasionally poke above
1kft this afternoon, but it seems likely that we'll largely
remain at IFR conditions, especially in the evening and overnight
hours. The exception to all this is in central MO, where cigs have
lingered just above IFR levels for the last several hours. Given
this trend, I've kept MVFR cigs in place at COU and JEF until
roughly sunset, when those cigs should come down.

The other aviation concern is the next round of showers expected
to move into the region this evening and overnight. This area of
showers and storms will drift across the region from west to east
and is likely to impact each terminal. There may be a few embedded
storms, but the odds of them impacting any of the terminals are
quite low, so I've kept the mention of thunder out of the
forecast.
