NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
606 am CDT Tue Sep 30 2014 


Short term: (through late this afternoon) 
issued at 224 am CDT Tue Sep 30 2014 


Focus continues to be temps with one more dry day expected. 


Cdfnt shows up well on regional radar and currently pushing into nrn 
MO and central Illinois. Mdls are in fairly good agreement with this fnt 
slowly sinking swd today, eventually reaching along a line from irk 
to near stl to slo before stalling. Have made only minor changes to 
the prev forecast, trending twd persistence along and S of the fnt. 
Area of St across ern Iowa and nrn Illinois continuing to move swd presents 
a forecast problem for today. The rap/hrrr seem to have the best 
handle on these clouds currently. However, even these mdls suggest 
these clouds will dissipate by noon today. Therefore, north of the fnt, 
have trended near the warmer guidance. 


Long term: (wednesday through monday) 
issued at 306 am CDT Tue Sep 30 2014 


Focus quickly turns to precip chances thru the end of the work 
week. 


Mdls are in very good agreement regarding mass fields thru the 
week. Not much change from the prev forecast as there is not much 
change to latest mdls from what the day shift had to work with. 
It appears the NAM and local WRF have caught up with the other mdl 
guidance regarding cdfnt timing later this week. However, the 
GFS/ECMWF/Gem have slowed timing of fropa compared to prev cycles. 


Have therefore raised temps slightly for sern portions of the County Warning Area 
on thurs. Have also raised pops for thurs night to account for the 
slower fropa timing. 


Otherwise, much cooler temps advecting into the region for the 
weekend and into next week behind the fnt.

Aviation: (for the 12z tafs through 12z Wednesday morning) 
issued at 603 am CDT Tue Sep 30 2014 


Backdoor cold front stretching from KUIN to k1h2 will continue to 
move southwest and bring IFR ceiling and MVFR fog to KUIN by 12z 
and perhaps to stl Metro terminals by 15z. Light and variable wind 
to become east/northeast in wake of the front. Expect this layer 
of stratus to lift and scatter out this morning. 


Specifics for kstl: 


Watching wall of stratus moving southwest toward terminal this 
morning behind backdoor cold front. Think we may have at least a 
few hours of IFR conditions before stratus lifts and scatters by 
this afternoon. Wind to become east/northeast.
