Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
536 am CDT Mon Oct 20 2014 


Short term: (through late this afternoon) 
issued at 301 am CDT Mon Oct 20 2014 


Scattered sprinkles and light rain showers developed across the 
southern half of the lsx County Warning Area overnight. Pcpn will gradually 
diminish today due to increasingly drier air behind a low pressure 
system which will continue moving from the Great Lakes into the 
northeastern US. 


Kanofsky 


Long term: (tonight through sunday) 
issued at 301 am CDT Mon Oct 20 2014 


Expect dry weather and seasonably mild temperatures to last 
through at least the middle of the week due to the influence of a 
highly amplified upper ridge across the central Continental U.S. As well as a 
surface ridge axis extending southwestward from Ontario through 
the Great Lakes and into MO/IL. A low pressure system will cross 
The Rockies and move into the plains towards the end of the week, 
and some of the precipitation associated with this system might 
clip the western County Warning Area on Thursday. Most of the model runs over the 
last few days were depicting a low pressure system which moved 
southeastward from The Rockies into the Southern Plains and then 
continued towards the Gulf of Mexico, but the 23/00z runs now 
depict a very different solution with a shortwave moving through 
the northern plains.

Aviation: (for the 12z tafs through 12z Tuesday morning) 
issued at 532 am CDT Mon Oct 20 2014

precipitation is expected as the front passes. Surface winds will 
veer from west to northwest behind the front. 


Specifics for kstl: southwest winds this morning will gradaully 
become northwesterely this afternoon behind a cold front. The
