 Flash Flood Watch  Statement as of 2:44 PM CDT on August 4, 2015


... Flash Flood Watch in effect from Wednesday morning through
Thursday morning...

The National Weather Service in St Louis has issued a

* Flash Flood Watch for portions of Illinois and Missouri...
including the following counties... in Illinois... Bond IL...
Clinton IL... Madison IL... Marion IL... Monroe IL... Randolph
IL... St. Clair IL and Washington IL. In Missouri... Boone MO...
Callaway MO... Cole MO... Crawford MO... Franklin MO... Gasconade
MO... Iron MO... Jefferson MO... Madison MO... Moniteau MO...
Montgomery MO... Osage MO... Reynolds MO... St. Charles MO... St.
Francois MO... St. Louis city MO... St. Louis MO... Ste.
Genevieve MO... Warren MO and Washington MO.

* From Wednesday morning through Thursday morning

* multiple rounds of showers and thunderstorms will bring
widespread rainfall amounts of 2 to 3 inches to the region
Wednesday morning through late Wednesday night. Locally higher
amounts are expected where thunderstorms repeatedly move across
the same locations.

* Heavy rainfall may result in flooding of low lying or poor
drainage areas... and ultimately dangerous flash flooding on
smaller creeks and streams. Significant rises on larger streams
and rivers will also be possible.

Precautionary/preparedness actions...

A Flash Flood Watch means that flash flooding is possible but not
imminent in the watch area. People in the watch area should be
aware of the possibility of heavy rainfall and flash flooding.
Check your preparedness requirements... especially if you live in
flood prone areas. Stay informed... and be ready for quick action
if flooding is observed or if a Flash Flood Warning is issued.

NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1208 am CDT Wednesday Aug 5 2015 


Short term: (through this evening) 
issued at 236 PM CDT Tuesday Aug 4 2015 


Isolated to scattered thunderstorms are expected to develop late 
this afternoon and early this evening near the front that is 
stalled just south of Interstate 70 and is being reinforced by an 
outflow boundary that is moving south from the convection that 
developed and crossed northern Missouri into west central 
Illinois. Mesoscale convective vortex and associated light rain shield in southeast 
Kansas is also moving northeast and will be near central Missouri 
for the evening hours. Will have to monitor trends and increase 
probability of precipitation if they can focus into a line/cluster. 


Cvking 


Long term: (overnight through next tuesday) 
issued at 236 PM CDT Tuesday Aug 4 2015 


A lead shortwave moving east-northeast from Kansas/Oklahoma in 
concert with a developing low level jet intersecting a nearly 
stationary surface boundary should result in numerous showers and 
thunderstorms developing and propogating across the County Warning Area from 
southwest to northeast tonight and Wednesday morning. Despite 
model quantitative precipitation forecast differences...mass fields are in good agreement. 
Utilized the bullseye of moisture convergence for highest probability of precipitation and 
quantitative precipitation forecast through Wednesday morning. 


Meanwhile...the main shortwave/vorticity maximum currently located across 
Wyoming will travel southeast tonight across the plains and into the 
lower Missouri River valley on Wednesday. This will provide 
additional synoptic lift and aid in reintensifying the low level jet 
by Wednesday afternoon across the County Warning Area. There is a conditional threat 
of severe thunderstorms that is highlighted by the day 2 convective 
outlook...but the main hazard appears to be locally heavy rainfall 
and flash flooding. 


Storm total quantitative precipitation forecast from tonight through Thursday morning will likely 
range from 1 inch in the far northern reaches of the County Warning Area to around 3 
inches from Interstate 70 and points south. Locally higher amounts 
will occur with training of thunderstorms. As I stated 
yesterday...the ground has recovered some from the record rainfall 
of June and early July and flash flood guidance is relatively high. 
That being said...widespread rainfall amounts of three inches over 
24 hours could lead to some local flash flooding...especially across 
the Eastern Ozarks. Have coordinated a Flash Flood Watch for 12z 
Wednesday through 12z Thursday to highlight this threat. 


Rain will come to an end on Thursday from west to east as the 
shortwave and low level jet focus thier attention toward the Ohio 
River valley and temporary subsidence ensues. 


Front is not expected to travel far and therefore the threat of 
showers and thunderstorms will continue through the weekend as we 
remain on the northeast periphery of the building upper level ridge.

Aviation: (for the 06z tafs through 06z Wednesday night) 
issued at 1201 am CDT Wednesday Aug 5 2015 


Main area of rain filling in over southwest MO currently and it 
now looks like much of the I-70 taf sites...cou and stl 
metropolitan...will be on the northern edge of this rain through much of 
Wednesday. Have maintained a rainy forecast with minimal 
restrictions, but a slight turn more to the south of this system 
could keep these areas now mostly dry. Uin may miss much of this 
system other than the outlow generated rain showers moving their way over 
the next few hours. Still looking at a break midday into early 
afternoon with new development 4-5 hours later heading towards 
early evening. Light easterly flow expected for much of the valid 
period. VFR conditons will give way to MVFR at most sites late 
tonight and Wednesday. 


Specifics for kstl: should be quiet and VFR until late tonight 
when the next round of rain with perhaps some thunderstorms and rain moves in. A 
this will probably continue until midday when it exits and a new, 
initially more scattered, round develops late afternoon and 
continues into the evening. Light easterly flow through the period 
with MVFR ceilings prevailing more on Wednesday.
