Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1158 PM CDT Tue Jul 22 2014 


Short term: (through late tonight) 
issued at 330 PM CDT Tue Jul 22 2014 


There is a considerable amount of uncertainty in the convective 
evolution and coverage tonight. Dew points in the 70s, strong 
heating and steep mid level lapse rates are currently contributing 
to SBCAPE of 3500-6000 j/kg across the northwest 2/3rds of the County Warning Area 
with the highest values across central and north central MO. There 
also is a significant cap in place due to warm mid level temperatures. 
The big question is when and how much of the cap will be reduced 
as the front moves southward out of Iowa and southeast Nebraska 
into northern MO this evening. Model solutions including the 
convection allowing models are quite varied on quantitative precipitation forecast and implied 
coverage. Recent runs of the hrrr are quite stingy on coverage 
with isolated storms at best. I don't have a great feel for what 
is going to occur, but the deterministic models suggest that height 
falls/cooling aloft should be sufficient to weaken the cap and 
allow for scattered development along front, mainly late this 
evening and especially overnight. I have attempted to follow this 
trend with the greatest coverage along/east of the MS river. The 
severe threat is conditional on development early enough this 
evening to realize the big cape, and the main threat would appear 
to be damaging winds given the warm air aloft.

Long term: (wednesday through next tuesday) 
issued at 330 PM CDT Tue Jul 22 2014 


The cold front should lie roughly from south central Illinois to near 
St. Louis into southwest MO at 12z and exit the County Warning Area by early 
afternoon. There will continue to be a threat of scattered showers 
and storms ahead of the advancing front. Temperatures should be 
cooler tomorrow with the main thrust of cooling and drying in the 
afternoon. Unseasonably deep upper troffing in the eastern U.S. 
Will keep a large surface high dominating the area Wednesday night 
into Friday, with most of this period dominated by lower humidity 
and below average temperatures. 


Beginning late Thursday night and into Friday the threat of precipitation 
will return in association with elevated showers/thunderstorms due to 
strong warm advection/moisture transport via a southwesterly low level jet ahead 
of the slowly retreating warm front and in association with impulses 
aloft dropping southeastward along the eastern periphery of the 
upper high. A cold front will then drop through the area Saturday 
afternoon-Sunday as a upper trof digs southeastward from the upper 
MS valley and into the Great Lakes bringing another threat of 
showers and thunderstorms. This upper wave will be part of large 
scale amplification of the upper air pattern across noam and will 
feature another deep trof over the eastern U.S. Through the first 
part of next week and send out July with another period of below 
average temperatures.

Aviation: (for the 06z tafs through 06z Wednesday night) 
issued at 1147 PM CDT Tue Jul 22 2014 


Tstms have struggled to maintain vs a strong cap this evening. 
Don't expect much to change overnight with isld activity 
continuing thru the night. Removed prevailing thunder group 
completely from kcou and KUIN and changed to thunderstorms in the vicinity at stl Metro 
sites at a later time. Band of ceilings near 2.5kft has dvlpd just 
behind the front...as indicated by the models...across nthrn MO 
and on into cntrl/nthrn Illinois. Expect this to follow the front south 
overnight and possibly expand some. MVFR fog is also possible 
towards mrng with a moist bndry lyr in place. Otherwise...expect 
diurnal cu and north/north-northeast winds aob 12kts. 


Specifics for kstl: 


Coverage for tstms has been minimal this evng as the convection 
struggles to survive against a strong cap...so have a thunderstorms in the vicinity group 
to cover the threat. A band of Post frontal high end MVFR cigs 
has dvlpd across nthrn Illinois and cntrl Illinois. This should push S in 
concert with the front. Otherwise...expect diurnal cu and a north/north-northeast 
wind aob 12kts.
