Area forecast discussion 
National Weather Service St Louis MO 
issued by National Weather Service Lincoln Illinois 
1223 PM CDT Tuesday Jun 30 2015 


Update... 
issued at 919 am CDT Tue Jun 30 2015 


With the passage of the shortwave to the east with its isolated 
convection have pretty dropped all pops from this morning except 
over the far eastern County Warning Area. Will monitor the weak cold front sliding 
southeast through northern Illinois for any afternoon development. 
Satellite imagery not showing any feature immediately upstream 
although the 12z NAM indicates a couple of weak h7 vorticity maxima 
that may or may not exist. Illinois counties within the County Warning Area will have the 
best chance for afternoon convection.

Short term... (through late this afternoon) 
issued at 434 am CDT Tue Jun 30 2015 


Scattered showers and storms are expected mainly this afternoon and 
mainly across west central and southwest IL, east of the Mississippi 
River as northwest flow shortwaves move southeastward through our 
area. The atmosphere will destabilize this afternoon due to daytime 
heating, especially across Illinois near the axis of the upper level 
trough centered over the Great Lakes region where mid level 
temperatures will be a little colder and hence lapse rates steeper. 
High temperatures should be a little warmer today compared to Monday 
and close to seasonal normals for the end of June. 


Gks 


Long term... (tonight through monday) 
issued at 434 am CDT Tue Jun 30 2015 


Showers and thunderstorms can be expected late tonight and Wednesday 
as a southwesterly low level jet brings strong low level warm air 
advection and moisture convergence to our forecast area, and a 
surface low approaches from Kansas while a front sags slowly southward 
through the region. The models were also depicting strong upper 
level divergence over our forecast area ahead of a northwest flow 
shortwave. There will be the potential for heavy rainfall which 
could result in more flooding. High temperatures on Wednesday will 
be cooler due to the increased cloud cover along with fairly 
widespread precipitation. As the surface low and front sag slowly 
southward the best threat for convection will shift to the southern 
portion of the area Wednesday night and Thursday. A surface ridge 
across the Great Lakes region will nose into northeast MO and west 
central Illinois likely ending the chance of precipitation across this 
area Thursday and Thursday night. Another upper level trough 
dropping southeastward into the region will keep the threat for 
showers/storms going at least across the western and southern 
portion of our area Thursday through Friday. The GFS model is a 
little stronger with the surface ridge over the Great Lakes region 
and is a little further south with its quantitative precipitation forecast than the NAM and the 
European model (ecmwf) models. Upper level troffing over the region coupled with a 
moist low level southerly flow should lead to at least scattered 
afternoon and evening convection Saturday and Sunday.

Aviation... (for the 18z tafs through 18z wednesday) 
issued at 1223 PM CDT Tue Jun 30 2015 


Mainly seeing a thick smoke layer aloft at midday, although some 
diurnal cumulus was forming east of the Mississippi River. KUIN most 
likely to see these lower clouds this afternoon. 17z obs have these 
as low as 2000 feet, but heights should increase quickly as the 
clouds track through west central Illinois. 


Main concern for this taf set will be with a developing convective 
complex to the northwest this evening. 12z model guidance showing 
this complex to be taking a southeast turn through Missouri after 
06z. Ensemble members keep the general edge of this cluster near the 
St. Louis Metro, so have hit kcou harder with thunderstorms and rain beginning around 
08z and the Metro taf's more as vcsh for now. The frontal boundary 
associated with this cluster will stall out near the I-70 corridor 
toward midday, increasing the risk of afternoon redevelopment. 




Specifics for kstl: 


Northwest winds around 10 knots this afternoon will gradually trend 
toward the north by mid evening. Winds to become light and variable 
late evening before trending more southerly Wednesday morning. Have 
kept thunderstorms and rain mention west of kstl for late night where the low level 
jet is more favorable, but some showers are likely by 10-11z. As a 
frontal boundary become stationary over the Metro, a better chance 
of thunder will be present by Wednesday afternoon, so have 
introduced a thunderstorms in the vicinity mention beginning around 18z.
