Area Forecast Discussion
National Weather Service Saint Louis MO
345 AM CDT FRI SEP 9 2016

.SHORT TERM...  (Through Late This Afternoon)
Issued at 345 AM CDT Fri Sep 9 2016

A band of thunderstorms containing heavy rainfall extended from MYJ
southeast through SUS to SAR.  Some of these storms were producing
rainfall rates as high as 1-2 inches per hour.  More complexes of
storms across portions of western MO and eastern KS will move
eastward through much of our forecast area for the rest of the
morning per the latest HRRR model runs.  With the recent rainfall
amounts from Thursday will issue a Flash Flood Watch for parts of
central MO into southwest IL along the I-70 corridor and including
COU, JEF, and the St Louis metro area until early Saturday morning.
Most of the current shower/storm activity should shift east of our
forecast area by noon, although could not rule out isolated to
scattered storms redeveloping along outflow boundaries from morning
convection this afternoon.  Should see enough partial clearing this
afternoon that high temperatures will be slightly warmer than
yesterday, and at or a tad above seasonal normals.

GKS

.LONG TERM...  (Tonight through Thursday)
Issued at 345 AM CDT Fri Sep 9 2016

(Tonight)

Another round of TSRA expected to be either ongoing or develop
shortly into the evening hours as an approaching cold front, strong
mid level shortwave, and persistent rich moisture thru the column
interact to produce what should be a widespread rainfall for the
area.  The most vulnerable areas that can be ascertained for now
will be locations that have already received heavy rainfall, namely
central MO into parts of east-central MO.  Will issue a Flash Flood
Watch thru 12z/Sat to highlight heigtened flash flood threat given
expected high rainfall rates in any TSRA and should not take as much
as areas outside of FFA for flooding.

(Saturday - Monday)

Northwest flow aloft and high pressure at the surface should equate
to a quiet wx period here.  Initially temps are expected to be below
average, but with southerly flow by late Sunday into Monday, temps
should rise back to above average levels by Monday.

GFS already develops rain chances by late Monday northwest of STL
metro, but prefer slower onset from EC.

(Tuesday - Thursday)

Rain chances should return by Tuesday with a cold front dropping
thru, with cooler air for Wednesday and Thursday with a 1028mb high
pressure settling over the Great Lakes.

TES

.AVIATION...  (For the 06z TAFs through 06z Friday Night)
Issued at 1127 PM CDT Thu Sep 8 2016

Period of clearing this evening resulted in formation of local
IFR ceilings and visibilities at KCPS and KSUS in fog. This will
likley improve over the next several hours as next batch of rain
and scattered thunderstorms moves in. Most instability is located
south of KCOU to KSTL line so still think most lightning will stay
south of there however will stick with VCTS to cover possibility
of some mostly in cloud lightning. Precip should end from west to
east towards dawn with ceilings improving to VFR.

SPECIFICS FOR KSTL: VFR conditions should last until around 09Z
when next batch of rain and isolated thunderstorms moves in
producing MVFR ceilings and visibilities. Most lightning should
remain south of KSTL where greater instability is
located...however some in cloud lightning is possible. Rain
should clear KSTL by around 14Z with VFR ceilings returning.
