NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
556 PM CDT Monday Aug 31 2015 


Short term: (through late tonight) 
issued at 304 PM CDT Monday Aug 31 2015 


Thunderstorms that produced heavy rainfall over the eastern County Warning Area this 
morning dissipated with the loss of the weak low level moisture 
convergence on the west side of the upper level low current centered 
over Indiana. More recently...atmosphere has become very unstable 
with MLCAPES of 2000-3000 j/kg with little cin. Shear axis has 
moved down into southern Missouri...so think best chance for 
thunderstorms will be over the Eastern Ozarks...particularly since 
that is traditionally where orographic lift has helped generate late 
afternoon/early evening thunderstorms in the past. Would expect any 
convection to diminish with loss of daytime heating. 


Additional thunderstorms will be possible once again late tonight 
over the eastern County Warning Area as both the NAM and GFS are pointing toward to 
some weak 925-850mb moisture convergence developing once again on 
the west side of the upper level low. Will go with a slight chance 
of thunderstorms late tonight through tomorrow morning.

Long term: (tuesday through next monday) 
issued at 304 PM CDT Monday Aug 31 2015 


(tuesday through thursday) 


Plan to go with a dry forecast from Tuesday afternoon through 
Thursday as forcing for thunderstorms looks weak as upper low moves 
east and upper ridge axis builds over the area which should suppress 
thunderstorm development. Don't expect much chance in the warm and 
humid conditions. Based highs on mixing down 850mb temperatures 
which are close to +20c. 


(Friday through monday) 


Forecast still looks on track for mainly dry weather early on for 
the Holiday weekend as the upper level ridge axis moves over the 
area which will suppress thunderstorms activity on Friday and 
Saturday. This ridge axis will begin to break down by Sunday...so 
will keep the slight chance of thunderstorms over northeast Missouri 
on Sunday. Will go with a wider chance of thunderstorms on Labor 
Day as both the GFS and European model (ecmwf) show the ridge axis moving south of 
the area at the same time a cold front enters the area from the 
north. Still went above normal through the Holiday weekend as we 
will stay in the same warm and humid airmass until the cold front 
moves through.

Aviation: (for the 00z tafs through 00z Tuesday evening) 
issued at 537 PM CDT Monday Aug 31 2015 


Upper level low/shear axis will remain in the region for another 
24 hours. It seems the best area for shower/thunderstorm 
develpment will be along moisture convergence regions that form on 
the west side of the upper low which will be over Indiana by 12z 
Tuesday. This should keep the developement east of the terminals 
overnight. Guidance keeps a 5-6 knot wind overnight and this may 
keep any fog at uin and cou from being very thick. Sus and cps may 
calm out, so will hit fog there a bit harder. 


Specifics for kstl: depending on how the radar looks, may keep a 
vcty in for an hour or may go dry. Otherwise persistance rules the 
forecast except for a slightly stronger southerly wind overnight. 
High pressure to the southeast will control the weather, generally 
dry and VFR.
