...HEAT ADVISORY FOR THE AREA EXPIRES AT 8 PM...
...HEAT ADVISORY FOR PORTIONS OF SOUTHERN IOWA WEDNESDAY...

.Temperatures continue to fall slowly this evening though humidity
levels remain rather high. Heat indices are still near the 100
degree mark...but will fall the remainder of this evening into the
80s after 10 pm this evening. 

Another day of high heat and humidity is likely in the same area
on Wednesday. A Heat Advisory has been posted for Wednesday
afternoon and early evening for parts of southwest Iowa where
confidence is high that heat indices will reach or exceed 105 
degrees.

...HEAT ADVISORY IN EFFECT FROM NOON TO 7 PM CDT WEDNESDAY...
...HEAT ADVISORY WILL EXPIRE AT 8 PM CDT THIS EVENING...

* TEMPERATURE...High temperatures in the low 90s with heat index 
  values around 105 degrees mid to late afternoon Wednesday. 

* IMPACTS...Prolonged exposure to heat and humidity may lead to 
  heat-related illness if precautions are not taken. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Heat Advisory means that a period of hot temperatures is
expected. The combination of hot temperatures and high humidity
will combine to create a situation in which heat illnesses are
possible. Drink plenty of fluids, stay in an air-conditioned
room, stay out of the sun, and check up on relatives and
neighbors.

   Take extra precautions, if you work or spend time outside.
When possible, reschedule strenuous activities to 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.

plans are to be outdoors the next couple of hours still use some
precaution.  

Very warm and humid conditions will return tomorrow. A heat
advisory may again be needed during the afternoon and evening
though it depends on thunderstorm coverage overnight tonight and
cloud cover through Wednesday morning which may help limit the 
hot conditions across the area Wednesday afternoon.

Area Forecast Discussion
National Weather Service Des Moines IA
328 PM CDT Tue Jul 11 2017

.SHORT TERM.../Tonight through Wednesday/
Issued at 328 PM CDT Tue Jul 11 2017

Excessive heat has been the weather highlight so far today. Dew
points have run a few degrees higher than guidance this morning,
with many locations along and south of Highway 30 in the mid to
upper 70s and heat indices near or exceeding 105 degrees. Little
relief tonight as the oppressive humidity limits cooling to the mid
to upper 70s.

A weak shortwave passing through today has supported scattered
elevated showers and storms to the north of a slowly advancing warm
front. This activity should dissipate and move out of the CWA in the
next couple hours. Although the atmosphere is highly unstable, warm
temperatures aloft will likely keep a firm cap on convection until
late tonight. Hi-res models continue to advertise a line(s) of
storms diving south out of Minnesota after 5z, likely in the
vicinity of a warm front that will be draped from north central to
east central Iowa. These storms may be severe with large hail and
damaging winds given that they will be working with an environment
characterized by 2000+ J/kg of MUCAPE rooted above 850mb and 25-30
kts of effective shear. Additional storms are possible in parts of
central and southern Iowa overnight into early Wed morning as theta-
e advection ramps up in concert with a strengthening low level jet.
Confidence is low at this time due to warm temperatures aloft, but
storms didn't have much difficulty firing last night in a similar
environment.

Heat will once again be an issue tomorrow as temperatures push back
into the 90s with high humidity. Another Heat Advisory has been
issued for parts of southwest Iowa where confidence is highest that
heat indicies will approach 105 degrees at times. The advisory may
be expanded further north and east similar to today, however at this
time the spatial extent of cloud cover and the impact on temps
remains in question. Next round of storms will be possible by late
afternoon as a stronger shortwave trough near the Canadian border
forces the aforementioned front back south into northeast
Nebraska/northwest Iowa. Weak cold air advection in the 850-700mb
layer will weaken the cap in the vicinity of the front and support
the development of isolated to scattered strong to severe storms.

.LONG TERM.../Wednesday night through Tuesday/
Issued at 328 PM CDT Tue Jul 11 2017

Front will move south through Iowa on Wednesday night with ongoing
convection at the beginning of the period. The convection will be
fed by strong instability south of the boundary and with strong
westerly flow aloft, sufficient shear for some organization into
strong to severe storms. This activity will sink southeast across
the state during the night as the front settles toward Missouri.
Much of the convection will have ended by Thursday morning as the
front slides south of Iowa and drier air pushes into the state.
This cooler and drier airmass will linger from Thursday into
Friday with Iowa on southern periphery of Canadian high pressure
sliding through Minnesota and Wisconsin.

After this period, attention turns to building ridge across the
intermountain west. Thermally, readings will warm underneath this
ridge and slide east toward the region into the weekend with
gradual warming. However, both GFS and Euro do indicate a boundary
sliding through Iowa on Sunday which will put a hold on the warm
briefly. However, the upper ridge is expected to slide east into
the central United States by the middle of next week with a large
area of much above normal temperatures into the Plains edging into
Iowa. Euro remains somewhat flatter in the amplitude while GFS is
more pronounced in the northern extent of the ridge. Both would
indicate the hot and humid conditions returning with the Euro
holding the southern edge of the westerlies closer to Iowa. This
would suggest a better threat of a convective system dropping into
the state, but still somewhat limited. For now, much of the
forecast will be dry into next week with temperatures remaining
above normal.

&&

.AVIATION.../For the 18Z TAFS through 18Z Wednesday afternoon/
Issued at 1232 PM CDT Tue Jul 11 2017

VFR conditions are expected over most of central Iowa through the
current TAF period. Scattered showers and storms in north central
Iowa may lead to temporary MVFR cigs this afternoon, including
KALO. Additional thunderstorms are possible overnight. VCTS was
mentioned at KALO/KMCW/KFOD where confidence is higher than
terminals further south. Any storm that impacts a terminal will
have the potential for gusty winds and heavy rain.
