... Heat advisory now in effect until 7 PM CDT Monday...

* timing... dangerous levels of heat and humidity will continue
through the weekend.

* Heat index values... up to 108.

* Impacts... the combination of hot temperatures and high
humidity will likely lead to an increased risk of heat-
related stress and illness. The very Young... the elderly...
those without air conditioning... and those participating in
strenuous outdoor activities will be the most susceptible.
Also... car interiors can reach lethal temperatures in a matter
of minutes. Beat the heat... check the backseat! Never leave
children or pets unattended in a vehicle... not even for a
minute.

Precautionary/preparedness actions...

Take extra precautions if you work or spend time outside. When
possible... reschedule strenuous activities to the early morning
or evening. Know the signs and symptoms of heat exhaustion and
heat stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work... the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency. Call 9-1-1 immediately.

NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1112 PM CDT Fri Aug 22 2014 


Update: 
issued at 1037 PM CDT Fri Aug 22 2014 


Main change to forecast for overnight was to cut pops back below 
mentionable levels. A secondary warm frontal type boundary does 
remain draped over central portions of the County warning forecast area. However...there 
is a lack of forcing aloft to trigger anything as low level jet resides over 
central Kansas with subsidence aloft from mid/upper level ridging. 
Peaking into Saturday...it appears some activity may approach far 
western or northwestern sections of the area as low level jet does veer to 
more westerly. Did not add any pops at this time but mid shift 
may need to take a closer look at this possibility. In 
addition...latest guidance keeps aforementioned boundary nearly 
stationary which could have implications on temps/dewpoints 
tomorrow as well.

Short term: (through late tonight) 
issued at 303 PM CDT Fri Aug 22 2014 


Similar to the past few days, isolated thunderstorms are expected 
across the southern County Warning Area due to terrain influences in the Eastern 
Ozarks. These storms will dissipate with the loss of daytime 
heating. 


Isolated to scattered thunderstorms are also possible across 
northeast MO/west central Illinois tonight in the vicinity of a warm 
front or outflow boundary. Favorable parameters overnight include 
precipitable water values near 2", 700 mb-500 mb lapse rates of 6 to 6.5 deg c/km, 
sufficient MUCAPE for elevated thunderstorms, and a strengthening 
low level jet. At this time, it looks like the best coverage should remain 
to the north of the County Warning Area. 


Kanofsky 


Long term: (saturday through next friday) 
issued at 303 PM CDT Fri Aug 22 2014 


Dangerous levels of heat and humidity will remain across the 
region through the weekend and into early next week. These 
conditions are due to an upper level ridge of high pressure across 
the central Continental U.S. Along with favorable surface winds that will 
maintain high dew points. The heat advisory has been spatially 
extended to cover additional counties in the Eastern Ozarks where 
dew points are no longer expected to mix out each afternoon. The 
lack of substantial mixing will likely result in at least 4 
consecutive days where heat index values exceed 100 degrees f. 
This is supported by the Missouri mesonet site in Crawford County 
near Cook Station, which was already reporting heat index values 
between 100-104 degrees f this afternoon. The heat advisory and 
the excessive heat warning have also been temporally extended 
through Monday evening now that models have reached improved 
agreement on the large scale upper air pattern through Tuesday. 
Some portions of the heat advisory, especially across northern MO 
and west central IL, might be canceled early if convective debris 
cloudiness interferes with heating. 


A cold front is forecast to end the stretch of hot/humid weather 
during the middle of the upcoming week. The best opportunity for 
widespread precipitation appears to be on Wed/Wed night with the 
cold front and passage of the upper trough, but the details are 
still uncertain this far in advance.

Aviation: (for the 06z tafs through 06z Saturday night) 
issued at 1111 PM CDT Fri Aug 22 2014 


Although there may be isolated thunderstorms across much of the 
area late tonight and Saturday in the humid and unstable 
environment, the best threat for more widespread convection should 
be north of the taf sites as a weak warm front lifts northward. 
For now will leave the tafs dry. Should be just mid-high level 
clouds outside of the convection late tonight and Saturday, 
including high level convective debris cloudiness. Light surface 
winds late tonight, then mainly weak sly surface winds on 
Saturday. 


Specifics for kstl: most of the convection should remain north and 
northeast of stl this forecast period. Just mid-high level 
cloudiness mainly late tonight and Saturday morning. The light surface 
wind will only increase to 6-8 kts Saturday afternoon, mainly from 
a sly direction.
