Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
710 PM CDT Tue Sep 30 2014 


Short term: (through late tonight) 
issued at 300 PM CDT Tue Sep 30 2014 


Cu field on vis satellite marking the front quite well and currently 
extends from through southwest Iowa to just north of St. Louis 
into southern Illinois. The front may sag a tad south over eastern MO 
into Illinois tonight as the surface winds back to more east-southeasterly, 
but the portion of the front in our area is largely expected to 
remain unactive. Further west/northwest however the low level jet shifts 
eastward from the plains overnight and becomes focused in the 
vicinity of the front across northwest MO into southwest Iowa 
favoring the highest shower/thunderstorm potential. Lows once 
again tonight coolest from the Eastern Ozarks through southern Illinois. 
May once again see some patchy radiational fog as well. 


Glass 


Long term: (wednesday through next tuesday) 
issued at 300 PM CDT Tue Sep 30 2014 


Active weather unfolds Wednesday and especially in the Wednesday 
night into Thursday evening time. Multicellular convection is 
expected to evolve on Wednesday afternoon across northwest MO and 
progress into central and northeast MO during the late afternoon. 
High temperatures will remain above average. 


Thunderstorms are expected to really get going on Wednesday 
night. At least one disturbance in the southwest flow aloft will 
traverse northern MO Wednesday night, and this combined with a 
veering and strengthening southwesterly low level jet will provide favorable 
convergence/lift for convection across northern MO into west 
central Illinois - especially along and north of a Jefferson City to 
Litchfield line. Repetitive convection and some locally heavy rain 
is certainly within the realm in this region. Thunderstorms remain 
likely Thursday and Thursday night with the potential for some 
strong-severe storms. This potential will probably be intimately 
controlled by mesoscale features. Showers and thunderstorms are 
expected to be ongoing Thursday morning across northern MO into 
central Illinois with a convective outflow boundary likely to their 
south. This boundary along with a pre-frontal convergence zone 
will dictate to some degree the best instability and low-level 
shear. Otherwise the advancing cold front and attendant short wave 
trof will provide deep large scale ascent, and deep layer shear is 
favorable for organized severe during the afternoon and evening 
with the orientation suggestive of a linear Mode. The vast 
majority of showers and thunderstorms should be located well into 
Illinois by 06z Friday and east of the County Warning Area by daybreak Friday. 


Friday is looking more and more like a typically blustery fall day 
with much cooler temperatures and gusty northwest winds. A deep 
long wave trof, which has become progressively stronger in the 
latest model runs, will dominate the eastern half of the nation 
from the weekend into early next week. This will result in below 
average temperatures for most of that period.

Aviation: (for the 00z tafs through 00z Wednesday evening) 
issued at 650 PM CDT Tue Sep 30 2014 


The backdoor cold front that pushed into the area this morning 
continues to slowly work south-southwest. It currently stretches from sthrn 
Illinois northwest thru ern into N cntrl MO and on into wrn Iowa. This bndry is 
fcst to stall this evng and then begin lifting north overnight as 
the assoc sfc low over the Dakotas lifts into sthrn Canada by 
Wednesday. Therefore winds should be eserly overnight bcmng sserly 
during the day tomorrow...staying aob 10kts. By Wednesday 
aftn...a bndry extending south from the original low in Canada to 
a new sfc low...that is fcst to form overnight across the cntrl 
High Plains...will approach cntrl MO Wednesday aftn. This should 
be the focus for at least isld/scttrd convection for cntrl and NE 
MO and possibly as far east as W cntrl Illinois. Not confident enough on 
the coverage/timing to include attm. Precip coverage becomes 
greater after the valid time of this fcst. Other than the clouds 
assoc with the convection late in the prd...can expect diurnal cu 
and some cirrus. 


Specifics for kstl: 


VFR fcst with east-southeast wind bcmng south-southeast Wed mrng as a frontal bndry moves 
north of the terminal. There is the potential for convection late in the 
prd...after 00z Thu...but late enough in the fcst and enough 
uncertainty in timing/coverage not to include attm.
