Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1134 PM CDT Thu Oct 23 2014 


Short term: (through late tonight) 
issued at 333 PM CDT Thu Oct 23 2014 


Shortwave trough responsible for the isolated light showers 
currently over the northern part of the County Warning Area will be pushing east of 
the area early this evening. Will go dry tonight as any remaining 
rain shouldn't be more than just sprinkles. The models show that 
there will be enough low level moisture for low clouds and some fog 
to develop over central and northeast Missouri as well as west 
central Illinois after midnight that will last past sunrise Friday 
morning. Have added mention of patchy/areas of fog to account for 
this. Went with lows close to current dewpoints.

Long term: (friday through next thursday) 
issued at 333 PM CDT Thu Oct 23 2014 


(friday through Sunday ) 


Still looks like this will be a dry period with above normal 
temperatures. Weak trough will move across Missouri and Illinois 
tomorrow, though moisture will be too limited in northwest flow to 
provide any rain chances. Still expect temperatures to climb above 
normal as winds turn out of the southwest ahead of cold front that 
will move through the area early on Saturday. Even though the cold 
front will move through early in the day, highs should be well into 
the 70s on Saturday as 850mb temperatures climb into the mid teens 
celsius under mostly clear skies. Temperatures should be similar on 
Sunday as the surface high moves off the the east with clear skies. 


(Monday through next thursday) 


Will keep the chance of showers and isolated thunderstorms going 
over the area from Monday night into Tuesday as both the GFS and 
European model (ecmwf) show a trough and an attendant cold front moving across the 
region during this time frame. While there are some minor 
differences with depth and speed of the trough, do not think these 
will affect timing of this system. Highs on Monday should be once 
again be well above normal ahead the cold front, but then cool down 
on Tuesday with passage of the cold front. Wednesday and Thursday 
will see highs closer to normal with cold air advection behind the 
front and 5-10c 850mb temperatures.

Aviation: (for the 06z tafs through 06z Friday night) 
issued at 1106 PM CDT Thu Oct 23 2014 


A band of clouds around 3000-5000 feet was moving southeastward 
through the taf sites this evening. Behind it partial clearing was 
leading to the development of patchy stratus and fog. Additional 
development of stratus clouds and fog can be expected late 
tonight with the models depicting plenty of boundary layer 
moisture. These low level clouds and fog will dissipate by late 
Friday morning. A swly surface wind can be expected late tonight 
and Friday. 


Specifics for kstl: stratus clouds and fog will develop late 
tonight with MVFR conditions. These low level, MVFR clouds and fog will 
dissipate by late Friday morning. Light sly surface wind will veer 
around to a swly direction late tonight, then back around to a 
sly direction again late Friday afternoon.
