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 29, 2:53 PM CDT, 1 hour 25 minutes earlier.

Area forecast discussion, Mar 29, 2:53 PM CDT, 1 hour 25 minutes before

Area Forecast Discussion
National Weather Service Saint Louis MO
253 PM CDT Thu Mar 29 2018

.SHORT TERM...  (Through Late Friday Afternoon)
Issued at 252 PM CDT Thu Mar 29 2018

It looks like the trof/weather system that has been affecting us for
a while will finally lift out of the area the next 12 hours. However
we have to get through the next 12 hours. If it were colder I would
say we have a nice winter storm with a good deformation zone
developing, but it is warm so all we have to worry about is rain.
That said, the HRRR and CONSHORT agree in holding some pops across
parts of east and southeast MO and southern IL through the evening.
It will likely end up being a narrow band, but will keep at least
chance pops going through 06z for much of the southern part of the
CWA. Drier air is filtering in from the north so improvement is on
the way for Friday. Patchy fog may be an issue overnight given the
wet ground, but will let the evening shift tackle that as it
develops. With cloud cover holding in for much of the are
overnight, have raised low temperatures to the warmer MAV levels.
Guidance for Friday looks good.

This will be my last forecast shift for the NWS as I am retiring as
of March 31. It has been a pleasure working with and serving
everyone across the 46 county area of the NWS St. Louis. Take Care.

Jim Kramper

.LONG TERM...  (Friday Night through Next Thursday)
Issued at 252 PM CDT Thu Mar 29 2018

Active pattern will continue over the weekend into next week as
global models show that the upper flow will be semi-zonal over
Missouri and Illinois.

The first chance of rain will come late Friday night into Saturday
night as GFS/ECMWF/Canadian show a shortwave trough and attendant
cold front dropping east southeastward from the northern Plains into
Missouri/Illinois.  After this first shortwave moves quickly off to
the east, a second shortwave will move across southern Missouri and
far southern Illinois late Sunday into Sunday night bringing another
chance of rain with some snow possibly mixed in based on forecast
soundings.  The best chance for showers will be Monday into Tuesday
ahead of deeper trough that will move across the area on Tuesday
night.  There will be stronger moisture transport ahead of it along
with some instability, so kept the chance of thunderstorms Monday
afternoon into Tuesday. Wednesday looks dry at this point behind the
upper trough as a surface high moves across the area before the next
upper trough and attendant front affects Missouri and Illinois next
Thursday.

Temperatures still look below normal through this period based on
clouds and rain chances as well as the ECMWF MOS and the GEFS mean
temps.

.AVIATION...  (For the 18z TAFs through 18z Friday Afternoon)
Issued at 1127 AM CDT Thu Mar 29 2018

The good news is the weather system will finally move east of the
region tonight and it looks like dry weather for Friday. The task
at hand will be when to end the rain and improve to VFR. HRRR and
some other short range models show a tendency to hold in rain
across parts of eastern MO and southern Il through the evening, so
at least MVFR will likely hold on their longer. That said, it
looks like UIN and COU will improve, the question will be whether
fog keeps conditions marginal. Most short range models keep the
VFR so will go with it. There is the possibility that MVFR clouds
could develop and hold in until Friday morning. Will be optimistic
for now and hold in MVFR longer than advertised, but go VFR by 12z
Friday.

SPECIFICS FOR KSTL: HRRR wants to hold in rain across STL through
the evening. CONSHORT pops surprisingly go along with that trend.
Thus I will likely hold some rain in until about 06z, and then
slowly improve. I went with a blend of the pessimistic/optimistic
models and it gives me VFR by 12z, so will go with it for now.
