Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
614 PM CDT Thu Sep 18 2014 


Short term: (through late tonight) 
issued at 321 PM CDT Thu Sep 18 2014 


High pressure centered across the Great Lakes continues to advect 
dry low level airmass into the region, which along with the 
September sun was able to break the stratus up across Illinois and 
the eastern half of Missouri. Expect there could be some valley fog 
that develops overnight, but otherwise quiet weather expected with a 
light southeast wind. 


Cvking 


Long term: (friday through next thursday) 
issued at 321 PM CDT Thu Sep 18 2014 


By Friday, surface ridge to move off to the east allowing warmer 
southerly flow to return to the region. Highs on Friday will be in 
the mid to upper 70s and in the low to mid 80s on Saturday. 


In the meantime, next weather system to move in by Saturday 
afternoon with showers and thunderstorms developing and spreading 
southeast across region as cold front moves through. Best chances of 
precipitation will be Saturday night before tapering off Sunday 
morning. 


On Sunday after system exits, begin to cool back down as next ridge 
of high pressure builds in. Cooler and drier weather to persist 
through the middle of next week with highs in the 70s and lows in 
the 50s.

Aviation: (for the 00z tafs through 00z Friday evening) 
issued at 608 PM CDT Thu Sep 18 2014 


Drying low level easterly flow prevails across the region thanks 
to expansive high pressure centered northeast of the Great Lakes. 
This should result in VFR conditions through this evening. 
Overnight some patchy radiational fog may occur reducing the 
visibility to 3-5sm. A little diurnal cu expected on Friday with a 
continuation of VFR flight conditions. 


Specifics for kstl: 


VFR flight conditions will prevail through the period. Light 
easterly winds tonight will veer to southeasterly on Friday.
