Wednesday afternoon and into the early evening.

* Heat index values... up to 108 due to temperatures in the lower

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.

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.

Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1118 PM CDT Tuesday Jul 28 2015 


Update: 
issued at 915 PM CDT Tuesday Jul 28 2015 


Biggest change was to extended the excessive heat warning through 
Wednesday in the St. Louis metropolitan and surround areas to the south. 
Temperatures won't cool off much tonight and should warm rapidly 
on Wednesday morning before the front pushes through the area. 
While we shouldn't see the extreme heat of the last few days, the 
heat index values will rise into the 100-106 range given the 
pooling of dew points in the middle and upper 70s and temperatures rising 
quickly into the lower 90s, and this will keep the longevity of 
dangerous heat levels going. 


Otherise the front will sag south tonight bringing scattered 
thunderstorms to portions of northern Missouri into west central 
Illinois.

Short term: (through late tonight) 
issued at 349 PM CDT Tuesday Jul 28 2015 


Dangerous heat indices are currently in the 105-117f range over 
the area with temperatures well into the 90s. Lambert is currently 
reporting 100. These values should fall off below criteria by 9 
PM. Isolated thundertorms are beginning to develop over the area 
as atmosphere is currently uncapped and MLCAPES are between 
3000-4000 j/kg. Any storms that do develop this afternoon may 
become strong and may produce gusty winds and heavy downpours 
before the storms diminish around sunset. There will be a better 
chance of storms later tonight as a cold front moves into the 
northern part of the County Warning Area. Have kept with best chances of 
thunderstorms north of I-70 where there will be the best 
combination of ascent from passing trough to the north with low 
level moisture convergence. 


Long term: (wednesday through next tuesday) 
issued at 349 PM CDT Tuesday Jul 28 2015 


(wednesday through friday) 


Have extended the heat warning for the far southern part of the County Warning Area 
into the tomorrow afternoon. Even though the cold front will move 
through the area early in the day...there won't be a strong push of 
cooler and drier air into southeast Missouri and southern Illinois 
until Wednesday night. Because of this, dewpoints will still be in 
the middle 70s with high temperatures climbing into the low 90s which 
will allow heat index readings to climb to around 105 degrees during 
the afternoon. Cooler and drier weather will move into the area for 
Thursday and Friday. 


Scattered thunderstorms will move across with the front on Wednesday 
morning. These storms will be mainly confined along and south of I- 
44 in Missouri and along and south of I-70 in Illinois during the 
afternoon. Thursday and Friday look dry at this point. 


(Saturday through tuesday) 


European model (ecmwf) and GFS continue to advertise northwesterly upper flow for early 
next week with a large high over the southwestern Continental U.S. And large 
mean trough over eastern North America. The operational GFS begins 
to flatten the flow over the ridge by Tuesday whereas the European model (ecmwf) 
keeps the flow over Midwest more northwesterly. The European model (ecmwf) has been 
more consistent and has support from the GFS ensemble mean, so will 
keep with it's solution. Will keep with a dry forecast over the 
weekend into Monday as high pressure moves across the area. By late 
on Tuesday a front will begin to approach the area from the north 
which will increase thunderstorms chances as the atmosphere becomes 
more unstable late in the day. Temperatures will be close to late 
July normals with 850mb temperatures between 18-22c.

Aviation: (for the 06z tafs through 06z Wednesday night) 
issued at 1101 PM CDT Tuesday Jul 28 2015 


Thunderstorms over the MO/Iowa border have been weakening a bit 
thus Storm Prediction Center does not anticipate a watch for NE MO and wc Illinois. Very 
unstable air but synoptic forcing is weak and daytime heating is 
gone. Still expect some storms to make it to uin most likely from 
7z - 10z. Models decreasng the coverage overnight but still think 
a mention as the front approaches is warranted. Another question 
is will storms form Wednesday afternoon. NAM has been consistent 
is developing some and it has been OK lately so will go with it 
some thunderstorms in the vicinity for the afternoon. 


Specifics for kstl: front will approach stl 12z-15z with a west 
wind inittially then northwest by 15z. Models weaken and diminish 
coverage of the convection over the MO/Iowa border as it moves east 
southeast overnight...however most keep some precipitaton along 
the front so will introduce a vcty for the early morning. NAM has 
consistently been re-developing for Wednesday afternoon so will 
also carry a thunderstorms in the vicinity for this time as well.
