 Public Information Statement  Statement as of 3:45 PM CST on March 4, 2015


... Illinois and Missouri severe weather awareness week 2015...
... This is flash flood safety day...

A flash flood is a rapid rise in creeks and streams... or serious
urban flooding... caused by heavy rain from thunderstorms... that
poses a threat to life and property. On average every year... floods
and flash floods kill more people nationwide than any other storm
hazard.

About half of all flash flood related deaths occur in vehicles.
Dont drive through flooded roads... especially if the water is
moving rapidly. Flooded or washed out roads are especially
difficult to see at night. Remember... turn around... don't drown.

A major problem in Illinois and Missouri is low water crossings.
These are designed to be crossed only when the water level is low.
When the water lever rises and is flowing swiftly due to recent
rain... turn around! Do not drown!

Do not let children play near storm drains... creeks or flooded
areas. It may look like fun but it can be deadly. As little as 6
inches of rapicly moving water can sewep an adult off their feet.

If you live near a creek or stream... evacuate to higher ground if
water rises rapidly or if a Flash Flood Warning is issued.

Urban flooding is also potentially dangerous. Heavy rain that
results in flooding of streets... viaducts and underpasses in an
urban area can pose a threat to motorists. Heavy rain can also
result in flooded basements... ponding of water in low spots and
rapid flooding of drainage ditches and storm sewer systems.

NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
631 PM CST Wed Mar 4 2015 


Short term: (through tonight) 
issued at 217 PM CST Wed Mar 4 2015 


All of the precipitation has changed to snow over our forecast area. 
As of 20z, heaviest band of snow has setup along a line from 
Reynolds County MO to Randolph County IL, in the warning area. 
Upwards of two inches has fallen in this area so far with lesser 
amounts to the north. With decent lift as next shortwave slides east 
northeast through southern MO, will see another 2 to 3 inches, maybe 
a bit more, before snow tapers off late this evening. Storm totals 
in our far south still look to be between 3 to 6 inches. For now 
will keep all headlines going. Otherwise, for areas north of I-44 in 
MO and I-70 in IL, it will be dry with skies remaining mostly 
cloudy overnight. As for low temps, single digits far north to the 
mid teens far south. 


Byrd 


Long term: (thursday through next wednesday) 
issued at 217 PM CST Wed Mar 4 2015 


(thursday through saturday) 


Sfc ridge will continue to build into the region thurs with northwest flow 
aloft. Based on upstream obs over ND/SD, have trended cloud forecast 
twd the more cloudy NAM/local WRF for thurs. Expecting high level 
clouds to pull sewd out of the region during the morning, with cumulus 
developing during the late morning into afternoon. Based on progd 
soundings across the region, any cumulus that develops has the potential 
for flurries. While going forecast contains more cloud cover than 
previously, have kept temps for thurs as-is as breaks in clouds shud 
help temps warm. 


Otherwise, little change to prev forecast thru Sat as prev forecast 
still appears on track. 


(Sunday through wednesday) 


Not much change to the prev forecast. Mdls are in rather good 
agreement overall. Northwest flow aloft dominates the extd and lacks any 
noteworthy trof. That said, a weak S/W and associated sfc cdfnt pass 
to the NE of the region late Sat which shud be monitored for future 
shifts in track. 


Overall, no precip expected thru the period with temps that 
gradually warm thru the period with above seasonal average temps by 
sun and into next week.

Aviation: (for the 00z tafs through 00z Thursday evening) 
issued at 540 PM CST Wed Mar 4 2015 


Ongoing storm system affecting the sthrn plains NE into the Ohio Vly 
will remain south of the terminals overnight. Widespread mid/high 
clouds will continue to stream NE this evng skies should clear 
either late tonight or early Thu mrng as the storm system moves 
east. Some model guidance is suggesting an area of 
stratus...possibly below 1kft...dropping out of Iowa towards 12z. 
Not confident in this solution...therefore have not included any 
mention of low clouds attm. Otherwise...N/NW winds around 10kts 
and clear skies. 


Specifics for kstl: 


Mid/high clouds will continue to stream overhead thru the 
night...finally pushing east towards 12z. Models are hinting at a 
small area of stratus dropping south along the MS rvr Thu mrng 
but to not have enough confidence in that solution to include 
mention attm. Otherwise expect north/northwest wind around 10kts and clear 
skies. Winds should go lght/vrb tomorrow evng as sfc ridge passes.
