 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 
1259 PM CDT Tuesday Aug 4 2015 


Short term: (through late this afternoon) 
issued at 358 am CDT Tuesday Aug 4 2015 




Quasi-stationary front looks to help provide focus for 
scattered thunderstorms during the day today. Best chances for 
storms throughout most of the day to be in close proximity to this 
frontal boundary where surface convergence is maximized. Front will 
likely waver around a bit and may sag back to the south and west 
(or at least the effective front) due to convective outflows. Mean 
frontal boundary likely to be placed from the northwest to southeast roughly 
through the middle of the County warning forecast area. 


Temperature guidance advertising highs in the 80s looked reasonable 
and did not deviate too much. Warmest highs will be across central 
and southeast Missouri on the warm side of the boundary with low 80s 
further to the north and east across northeast Missouri through 
south-central Illinois. 




Gosselin 


Long term: (tonight through monday) 
issued at 358 am CDT Tuesday Aug 4 2015 




(tonight - thursday) 


A lead shortwave trough will approach the region embedded within west-northwest 
flow aloft. Dcpva ahead of this feature coincident with a 
strengthening southwesterly low level jet at 850 hpa looks to produce a good 
chance of showers and storms...particularly late tonight along the 
Missouri River. 


Unfortunately...models begin to diverge quite substantially already 
on Wednesday and thereafter. Main differences lie with speed of 
secondary shortwave trough/its interaction with lead shortwave and 
track/speed of low-level cyclone. Went with a model consensus for 
probability of precipitation and other sensible weather elements for Wednesday through 
Thursday. Regardless...the midweek timeframe appears to be quite 
active with the primary concern for heavy rainfall which may result 
in flash flooding and renewed river/stream flooding. Late Wednesday 
afternoon and especially Wednesday night appear to be of heightened 
concern for heavy rain as both the GFS/NAM have strong moisture 
convergence on the nose of a 40-50 knots low level jet...good upper-level 
support...precipitable water values over 2 inches...and favorable thermodynamic 
profiles all highlighting possibility of heavy rain. 


Due to high degree of uncertainty for midweek and...at least at the 
moment...fairly receptive soils...will hold off on issuing a Flash 
Flood Watch for now. One may be needed however down the Road if 
model consensus rises and/or parts of the County warning forecast area receive sufficient 
rainfall over the next 24 hours to saturate soils. 


Active weather by Thursday afternoon at least should push off to the 
south and east with subsidence behind Stout secondary vorticity maximum. 
Thursday afternoon looks fairly dry with only schc/chance probability of precipitation and high 
temperatures slightly below normal. 




(Friday - monday) 


Upper-level anticyclone begins to flex its muscles across the 
Southern Plains beginning Friday and heading into this upcoming 
weekend. Complexity of forecast stays quite high though as middle- 
Mississippi Valley stays on the northeastern periphery of 
aforementioned high. Too difficult to pin down exactly when there 
will be chances for showers/storms...due to high degree of 
uncertainty with timing of disturbances within the "ring of fire". 


Temperatures will likely be on the increase both day and night 
compared to the middle of this week as heights rise and 850-hpa 
temperatures warm back of +20c. Near normal temperatures are most 
likely for this period...but bust potential during each day will be 
high as in the absence of clouds/storms temperatures may soar well into the 
90s whereas a convective complex coming down from the middle-Missouri 
Valley at the right time could have highs in the 70s/low 80s. Due to 
very high level of uncertainty with probability of precipitation/cloud cover...relied on 
model consensus for temperatures.

Aviation: (for the 18z tafs through 18z Wednesday afternoon) 
issued at 1247 PM CDT Tuesday Aug 4 2015 


Specifics for kuin: ongoing sh/ts at taf issuance will persist for 
the next few hours before diminishing with the loss of daytime 
heating. A second round of precipitation is expected late overnight 
but the timing is uncertain near KUIN because it is farther north. 


Specifics for kcou: two periods of sh/ts are expected during the 
next 24 hours. The first period will occur this afternoon due to 
diurnal heating in vicinity of a quasistationary boundary ahead of an upper 
level disturbance. These storms will likely diminish after sunset. 
The next period will occur late tonight and last into tomorrow. 
These sh/ts will occur ahead of a second upper level disturbance. 
The timing for the overnight precipitation is still uncertain but 
will probably not begin until after 03z at kcou. 


Specifics for kstl, ksus, kcps: two periods of sh/ts are expected 
during the next 24-30 hours. The first period will occur this 
afternoon due to diurnal heating in vicinity of a quasistationary boundary 
with support from an upper level disturbance. These storms will 
likely diminish after sunset. The next period will occur late 
tonight and last into tomorrow. These sh/ts will occur ahead of a 
second upper level disturbance. The timing for the overnight 
precipitation is still uncertain but will probably not begin until 
after 06z in the St Louis metropolitan area.
