Short term: (through late this afternoon) 
issued at 348 am CDT Tue Jul 22 2014 


During the day today the upper ridge will remain in place with 
surface temperatures expected to warm up into the low to mid 90s. 
Low level moisture continues to increase as well, so will see heat 
indicies between 100 and 105 for central and northeast MO as well as 
west central Illinois.

Long term: (tonight through monday) 
issued at 348 am CDT Tue Jul 22 2014 


In the meantime, cold front associated with next weather system 
to move into far northern portions of MO by 00z Wednesday. Short 
term models begin to develop complex along frontal boundary around 
this time and track it to the south and southeast through forecast 
area tonight. Some differences on timing and coverage between the 
models, so went with a blend and increased pops to likely late 
this evening and into the overnight hours as it moves through. 
Despite all of the instability and moisture, some concern about 
mid level capping, but confident cap will weaken sufficiently to 
allow storm development. With decent CAPES, moisture and 
instability, Storm Prediction Center has placed northern portions of forecast area in 
a slight risk for tonight with main threats being large hail and 
damaging winds. 


System to continue tracking south through southern portions of 
forecast area Wednesday morning, before tapering off Wednesday 
afternoon. As for highs on Wednesday, will range from the low 80s 
far north to around 90 far south. 


By Wednesday night, surface ridge begins to build in and bring in 
drier and cooler weather for the last half of the work week. Highs 
on Thursday will be in the upper 70s to mid 80s. 


Surface ridge to move off to the east by Friday with a warm front 
developing across region with elevated convection possible for 
portions of forecast area Friday and Friday night. Then as main cold 
front moves into region on Saturday, will see additional rounds of 
storms through Sunday night before system exits region on Monday. 
Temperatures to moderate through the weekend once again.

Aviation: (for the 12z tafs through 12z Wednesday morning) 
issued at 604 am CDT Tue Jul 22 2014 


VFR conditions are anticipated today with southwest wind around 
10kt. Cold front will move across the area this evening and 
overnight with thunderstorms expected to develop along and ahead 
of the front. Conditions could dip into MVFR range with 
thunderstorms, otherwise a wind shift to the northwest will occur 
with the front. 


Specifics for kstl: 
expect thunderstorm complex ahead of the cold front will move 
across the terminal around 06z with a temporary reduction in 
visibility, a wind shift to the northwest and potential for some 
gusts to 25kt. Conditions will rapidly improve on Wednesday with 
north wind.
