NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
324 am CDT Monday Aug 3 2015 


Short term: (through late this afternoon) 
issued at 316 am CDT Monday Aug 3 2015 


Surface front extends from northern Illinois through southern 
Iowa into far northwestern Missouri at this hour. This front will 
move south today and begin to realign itself under the 
northwesterlyupper flow aloft so that it will extend from 
central Missouri into southeast Missouri by later this afternoon. 
While there will not be any significant shortwave troughs moving 
through the area today to provide enhanced ascent along the 
front...there will be enough low level convergence along it to 
support going slight chances. MLCAPES by later this afternoon will 
be in the 2000-3000 j/kg range. 


Temperatures will still be warm ahead of the front in the southern 
County Warning Area where mixing will be above 850mb. Temperatures will still 
likely be in the lower to middle 90s along and south of I-70 ahead 
of the cold front where mixing will be above 850mb. 


Britt 


Long term: (tonight through sunday) 
issued at 316 am CDT Monday Aug 3 2015 


(tonight through wednesday) 


The surface front will move south of the area by Tuesday morning and 
remain south of the area through Wednesday. Rain chances will be 
greater tonight into Tuesday as both the NAM and GFS are showing an 
increase in low level moisture convergence overnight over northeast 
and east central Missouri overnight. By Tuesday and Wednesday...two 
significant shortwave troughs will move across Missouri and 
Illinois with a corresponding increase in low level moisture 
convergence. This justifies the going high chance or likely 
chances for thunderstorms. 


(Thursday through sunday) 


Wavy front will remain over the area at least through Friday 
keeping thunderstorm chances in the forecast. Heights will 
increase over the area by the weekend with 850mb temperatures near 
20c. This should cause temperatures to climb back above normal.

Aviation: (for the 06z tafs through 06z Monday night) 
issued at 1149 PM CDT sun Aug 2 2015 


I've included a short tempo group at the beginning of the taf 
period for kcou due to weakening cluster of storms tracking 
southeast towards the terminal. Otherwise I expect a dry night 
with VFR flight conditions. A cold front will move across the area 
on Monday. There will probably be isolated-scattered storms 
(20-30% probability) with the front in the afternoon. However 
given the low coverage and uncertainty with location and terminal 
impacts, I have opted to not mention any thunder in the tafs at 
this time. 


Specifics for kstl: 


VFR flight conditions are expected to dominate the taf period. A 
cold front will move across the area on Monday. There will 
probably be isolated-scattered storms (20-30% probability) with 
the front in the afternoon. However given the low coverage and 
uncertainty with location and terminal impacts, I have opted to 
not mention any thunder in the kstl taf at this time.
