Area forecast discussion 
National Weather Service St Louis MO 
232 am CDT Wed Oct 1 2014 


Short term: (through late this afternoon) 
issued at 226 am CDT Wed Oct 1 2014 


As expected the convection stayed west of the County Warning Area overnight with 
parts of northeast Kansas, eastern Nebraska, western Iowa, and 
northern Missouri picking up some hefty precipitation totals from 
training convection. Model guidance depicts a slow eastward movement 
to the convection this morning, with additional storms likely firing 
during the afternoon across northwest or central Missouri. The 
front that settled to our south yesterday evening will lift north as 
a warm front today, allowing temperatures to rise well above average 
again. 


Cvking 


Long term: (tonight through tuesday) 
issued at 226 am CDT Wed Oct 1 2014 


Thunderstorms should increase in coverage and intensity tonight 
as next upper level disturbance rounding the base of the large 
scale trof at the moment lifts northeast across the Southern 
Plains into the Midwest. Combine this synoptic lift with a 
strengthening low level jet and the result should be some hefty 
convection across northern Missouri into west central Illinois. 
Training convection could lead to some rainfall totals in excess 
of 2 inches and the threat of flash flooding will need to be 
monitored. Will not issue a watch due to dry antecedent 
conditions. Slight risk of severe thunderstorms from Storm Prediction Center reaches 
into central and northeast Missouri. Could certainly be some 
reports of large hail and damaging winds with the strongest cells. 


Complex of thunderstorms will be weakening and exiting into weather forecast office ilx 
area Thursday morning with attention turning to the cold front 
moving into Missouri from the west. Thunderstorms again expected to 
develop, maybe in waves on Thursday, along and ahead of the 
front. These storms will be capable of producing the full gamut 
of severe weather, especially given the favorable shear profile. 
The exact timing, location, and severity of convection will be 
modulated by mesoscale features such as outflow boundaries. 


Expect most of the convection to be exiting the area by 06z Friday 
with only a few showers lingering after midnight as the cold front 
sweeps across the County Warning Area. 


Friday looks windy and much colder as upper level low moving 
southeast across the upper Midwest deepens the long wave trof as it 
slides east of the County Warning Area. Colder than normal conditions expected on 
Saturday with temperatures only rising into the 50s. 


Temperatures to slowly warm the remainder of the extended but there 
is some indications that this long wave trof will stay parked to our 
east, keeping northwest flow alive and well overhead. A disturbance 
moving southeast within that flow could bring few sprinkles or rain 
showers to the County Warning Area on Sunday/Sunday night.

Aviation: (for the 06z tafs through 06z Wednesday night) 
issued at 1138 PM CDT Tue Sep 30 2014 


Ongoing convection continues to track from cntrl and ern Kansas into 
southeast NE and on into wrn Iowa. This should continue most of the night 
as the low level jet remains anchored in that area overnight. This 
convection will eventually reach the local sites sites but will it 
will take until late Wednesday aftn to reach cntrl MO...and nearly 
midnight for it to reach the stl Metro area. Most of the taf prd 
should be dry and VFR. In the near term...ksus may once again 
have steam fog prior to sunrise. With the wind direction aiming 
the fog away form the terminal...not sure how dense it will be. 
The rain showers/thunderstorm threat will continue after the end of the valid prd. 


Specifics for kstl: 


VFR fcst thru 06z Thursday...then a chance for shra/tstms.
