Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
634 am CDT Thu Jul 31 2014 


Short term: (through tonight) 
issued at 307 am CDT Thu Jul 31 2014 


Expect highs in the upper 70s to mid 80s followed by overnight 
lows in the lower 60s. Such temperatures are 3-10 degrees below 
average for this time of year. Light rain is possible across the 
extreme southern County Warning Area today on the northern fringes of an area of 
precipitation which is being generated by a shortwave moving from 
OK into Arkansas. Isolated to scattered precip is also possible late 
this afternoon and early tonight across the northern County Warning Area ahead of 
an approaching shortwave which is diving south-southeastward from 
ND/Minnesota per 06z water vapor imagery. 


Kanofsky 


Long term: (tomorrow through wednesday) 
issued at 307 am CDT Thu Jul 31 2014 


Diurnal instability combined with lift ahead of occasional weak 
shortwaves might produce iso-sct sh/ts over the next couple of 
days, especially during the afternoon hours. Slightly cooler than 
average temperatures will continue until the northwest flow 
pattern aloft begins to change over the weekend, eventually 
becoming quasizonal. After an upper ridge de-amplifies and shifts 
into the plains early next week while surface winds turn 
southerly, seasonable levels of heat/humidity should return to the 
region. The next opportunity for widespread rainfall appears to be 
associated with a potential synoptic scale system during the 
middle of next week.

Aviation: (for the 12z tafs through 12z Friday morning) 
issued at 629 am CDT Thu Jul 31 2014 


Ongoing radiational fog should dissipate by 13-14z with VFR flight 
conditions expected to dominate through the remainder of the day 
and evening. Clouds will consist primarily of diurnal cu and some 
high clouds. Given the persistence of light winds, during the 
overnight hours we should see radiational fog once again develop. 


Specifics for kstl: 


VFR flight conditions expected to dominate through the forecast 
period. The wind will be light and clouds will consist primarily 
of diurnal cu and some high clouds.
