What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at May 7, 4:17 PM CDT, 41 minutes earlier.

Area forecast discussion, May 7, 4:17 PM CDT, 41 minutes before

Area Forecast Discussion
National Weather Service Saint Louis MO
417 PM CDT SAT MAY 7 2016

.SHORT TERM...  (Through Late Tonight)
Issued at 306 PM CDT Sat May 7 2016

Clusters of thunderstorms have developed this afternoon ahead of
a southward-moving cold front. These storms are expected to
affect parts of the greater St. Louis metropolitan area late this
afternoon and early this evening, particularly between 4-8pm.

The atmosphere has been destabilizing ahead of these storms due
to ample insolation and moisture pooling along the front beneath
H7-H5 lapse rates of 6.5-7 deg C/km. Models depict 0-6km bulk
shear values increasing to around 30-40 kts, which will be
sufficient for strong to severe thunderstorms across eastern MO
and southwestern IL over the next few hours. The primary threats
are damaging wind gusts (especially if the cluster becomes better
organized) and large hail in the strongest cores.

The front will stall across the region tonight. Additional
convection is possible overnight invof the stalled bdry.

Kanofsky

.LONG TERM...  (Sunday through Next Saturday)
Issued at 306 PM CDT Sat May 7 2016

Expect pds of active wx through the middle of the week.

The aforementioned stalled cold front will lift back northwards
as a warm front on Sunday due to the development of a surface low
pressure center near the OK/TX panhandles, which itself develops
in response to the northeastward advance of a closed upper low
lifting out of the western CONUS. The passage of the warm front
puts the entire CWA in the warm sector until a cold front
eventually moves across the region on late Wed night into Thu.

Thunderstorms are expected to develop over KS/NEB/wrn MO late
Sunday night once the LLJ increases, forming an MCS and
progressing into the LSX CWA late Sunday night into Monday. There
may be a lull in pcpn on Monday afternoon. SHRA/TSRA coverage
should increase again on Monday night into Tuesday due to moisture
convergence ahead of an approaching negatively tilted upper trough
and favorable jet dynamics (LER H25 jet). Additional pcpn is
expected ahead of a cdfnt on Wed night into Thu. Once the cdfnt
has moved through the region, quiet wx is expected for a few fcst
pds. Another low pressure system moves across the northern plains
late next week which could bring a chance of rain to the area.

Kanofsky

&&

.AVIATION...  (For the 18z TAFs through 18z Sunday Afternoon)
Issued at 1242 PM CDT Sat May 7 2016

A cold front will sag S into the area this aftn and continue to
drift S thru the night ending up S of I-70 by Sun mrng. Batch of
SHRAs/TSTMs dropping SE out of wrn/sthrn IA this mrng will
continue to slide along the front into NE MO/W Cntrl Il this
aftn...potentially impacting the KUIN terminal between 19-20Z.
Activity should continue to push SE and intensify. The wrn edge of
this activity may clip some of the STL metro sites after 21Z.
Addtnl SHRAs/TSTMs may percolate thru the night and have VCSH to
cover that threat due to uncertainties about timing...placement
and coverage. The bndry begins lifting back N tomorrow...current
thinkning is that it should be N of I-70 before aftn convection
begins to initiate.

Specifics for KSTL:

Precip may impact the terminal late this aftn as a cluster of
SHRAs/TSTMs passes to the NE of the terminal. If the terminal is
impacted by a stronger core...then conditions could drop to IFR in
heavy rain. Otherwise expect VFR conditions with scttrd SHRAs
thru the night assoc with a cold front moving S of the terminal.
This bndry is fcst to lift back N thru the terminal tomorrow...
temporarily ending the precip threat.
