NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
332 am CDT Wed Jul 23 2014 


Short term: (through late this afternoon) 
issued at 330 am CDT Wed Jul 23 2014 


Cold front to continue tracking south through forecast area this 
morning, before exiting region early this afternoon. Despite decent 
cap over area, could still see some isolated/scattered storms 
develop as front moves through. Highest pops will be this morning 
for southern half of cwa, then taper off rather quickly after 18z. 
As for highs today, will range from the low 80s far north to around 
90 far south. Drier/cooler air is lagging behind boundary, so with 
dewpts still in the 70s could see heat indicies approaching 95 early 
this afternoon.

Long term: (tonight through tuesday) 
issued at 330 am CDT Wed Jul 23 2014 


By tonight, surface ridge begins to build in and bring in drier and 
cooler weather for the last half of the work week. Lows tonight will 
be in the mid 50s to near 60. Highs on Thursday will be in the upper 
70s to low 80s. 


Surface ridge to move off to the east by Friday with a warm front 
developing across region with elevated convection possible for 
northern portions of forecast area late Thursday night through 
Friday night. Then as main cold front moves into region on Saturday, 
will see additional rounds of storms through Sunday before system 
exits region Sunday night. Temperatures to moderate through the 
weekend once again. Models are indicating 850 temps between 24c and 
26c on Saturday and if they mix down, could see highs in the upper 
90s for portions of the area. For now raised highs a few degrees for 
Saturday, into the upper 80s to mid 90s. 


Beyond the weekend, surface ridge builds in once again for early 
next week with highs cooling off into the upper 70s to mid 80s for 
Monday and Tuesday.

Aviation: (for the 06z tafs through 06z Wednesday night) 
issued at 1147 PM CDT Tue Jul 22 2014 


Tstms have struggled to maintain vs a strong cap this evening. 
Don't expect much to change overnight with isld activity 
continuing thru the night. Removed prevailing thunder group 
completely from kcou and KUIN and changed to thunderstorms in the vicinity at stl Metro 
sites at a later time. Band of ceilings near 2.5kft has dvlpd just 
behind the front...as indicated by the models...across nthrn MO 
and on into cntrl/nthrn Illinois. Expect this to follow the front south 
overnight and possibly expand some. MVFR fog is also possible 
towards mrng with a moist bndry lyr in place. Otherwise...expect 
diurnal cu and north/north-northeast winds aob 12kts. 


Specifics for kstl: 


Coverage for tstms has been minimal this evng as the convection 
struggles to survive against a strong cap...so have a thunderstorms in the vicinity group 
to cover the threat. A band of Post frontal high end MVFR cigs 
has dvlpd across nthrn Illinois and cntrl Illinois. This should push S in 
concert with the front. Otherwise...expect diurnal cu and a north/north-northeast 
wind aob 12kts.
