Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
1236 PM CDT TUE JUN 21 2016

.SHORT TERM...  (Through Late This Afternoon)
Issued at 307 AM CDT Tue Jun 21 2016

Convection continues to develop across parts of eastern Nebraska,
southwest IA and northwest MO in a zone of 850 mb moisture convergence
on the nose of a southwesterly low level jet, and also along the
western extent of a cold front that has become stationary and
along an outflow boundary from earlier convection. This activity
should continue to drop southeastward into central MO early this
morning, but should tend to weaken by late morning. Some
redevelopment is forecast this afternoon along this front as it
becomes oriented northwest to southeast across central and
southeast MO into southwest IL. Should have slightly cooler high
temperatures behind the front across northeast MO and west central
IL, but also further south as well due to cloud cover and
precipitation.

GKS

.LONG TERM...  (Tonight through Monday)
Issued at 307 AM CDT Tue Jun 21 2016

More convection is expected tonight as the front begins to lift
northeastward as a warm front as surface low pressure develops
over the northern Plains. Low-mid level warm air advection is
expected over this front on the nose of a southwesterly low level
jet. The best coverage of convection should occur across northeast
MO and west central and southwest IL. Most of the showers/storms
should shift northeast of our forecast area on Wednesday. Very
warm and humid conditions can be expected on Wednesday with
southwest winds and potentially little cloud cover. Will probably
need a heat advisory for the St Louis metro area with afternoon
heat indices likely topping out around 105. As the surface low
shifts eastward into the Great Lakes region it will drag a cold
front southeastward through our forecast area Wednesday night and
Thursday. While there may be isolated showers/storms across
northeast MO and west central IL Wednesday night along this
front, the better threat for convection will likely be across
southeast MO and southwest IL Thursday afternoon. Slightly cooler
temperatures can be expected Thursday night and Friday as a
surface ridge moves through the Great Lakes region. There will
likely be scattered showers/storms across central and southeast MO
on Friday ahead of a weak shortwave with return flow behind the
retreating surface ridge. An upper level trough moving eastward
through the northern Plains will send a weakening cold front
southeastward through the forecast area Sunday afternoon and
night. This will be the focus for at least scattered convection.

.AVIATION...  (For the 18z TAFs through 18z Wednesday Afternoon)
Issued at 1230 PM CDT Tue Jun 21 2016

Overnight MCS has weakened considerably over the past couple of
hours with just a few showers/storms remaining. Believe much of
the rest of the afternoon and early evening will remain quiet with
additional showers and storms developing along and to the
northeast of a retreating warm front. Believe best chance will be
along/east of the Mississippi River overnight tonight with best
chance at KUIN so did prevail thunderstorms at that site. KCOU is
believed to stay dry through the valid TAF period with the metro
TAF sites likely on the western edge of activity so have a VCTS
group in for those sites. Light/variable winds tonight will become
southerly and increase to 10-15 knots by midday Wednesday.

Specifics for KSTL:

Believe much of the rest of the afternoon and early evening will
remain quiet though will watch a small cluster entering
southwestern Pike County in Missouri as of 1730 UTC. Additional
showers and storms should develop along and to the northeast of a
retreating warm front near the MO/IA border by mid evening and
move southeastward in time. Better chances of showers/storms will
be to the northeast of terminal but concerned frontal boundary may
be a bit further southeast than previously predicted due to the
earlier effects of the MCS. Have therefore added a VCTS group in
for now. Light/variable winds tonight will become southerly and
increase to 10-15 knots by midday Wednesday.
