...HEAT ADVISORY IN EFFECT FROM 2 PM FRIDAY TO 8 PM EDT
SATURDAY...

The National Weather Service in Indianapolis has issued a Heat
Advisory, which is in effect from 2 PM Friday to 8 PM EDT
Saturday. 

* TEMPERATURE...High temperatures will be in the low to mid 90s,
  with peak heat index values of 100 to 110 degrees.

* IMPACTS...There will be an increased risk of heat stress and
  heat illness for everyone, but especially among vulnerable
  populations, such as the very young, the elderly, the infirm,
  those without access to air conditioning, and those spending
  significant time outdoors. Pets are also susceptible to heat
  illness. Heat illnesses can occur very quickly. Additionally, 
  car interiors will reach lethal temperatures in a matter of 
  minutes.

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.

What forecasters said that day

The local office's own words before this heat advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Indianapolis, IN wrote its last area forecast discussion before this heat advisory went out at Jun 28, 1:34 PM EDT, 1 hour 45 minutes earlier.

Area Forecast Discussion
National Weather Service Indianapolis IN
134 PM EDT Thu Jun 28 2018

.UPDATE...
The AVIATION Section has been updated below.

&&

.SYNOPSIS...
Issued at 323 AM EDT Thu Jun 28 2018

The hottest air of the season is poised to expand into central
Indiana late week into the weekend as a strong upper level ridge
centers over the region. The ridge will shift west into early next
week...enabling a frontal boundary to slip into the region from the
north by late weekend. This will help to pull temperatures down
slightly for the first half of next week while bringing better
chances for scattered thunderstorms.

&&

.NEAR TERM /Today/...
Issued at 1024 AM EDT Thu Jun 28 2018

The primary change made during this morning update is in regards
to the afternoon max temp. Boosted the max a degree or so this
afternoon as current temp trends were outpacing the forecast and
MAVMOS guidance also agreed. The previous discussion follows...

Issued at 323 AM EDT Thu Jun 28 2018
Mainly clear skies over central Indiana early this morning as
weak high pressure has built in from the north. Convection has
been firing this morning along the remnant frontal boundary and
instability gradient which resides from central Missouri southeast
into western and southern Kentucky. Muggy this morning with 07Z
temperatures ranging from the mid 60s to the lower 70s.

The weak surface high will maintain dry weather over the forecast
area today as upscale convective development will focus along the
front which will remain to our southwest. Model soundings show a
solid capping inversion which should only strengthen through the
course of the day as warming commences aloft. Expect some diurnal cu
formation with a lingering low level thermal trough over the
region...but the cap should limit overall vertical extent.

Temps...plenty of sunshine and moderating temperatures in the
boundary layer support a return to warmer weather compared to the
last few days. Low level thermals are supportive of the warmer
MAVMOS with highs likely to top out in the upper 80s to lower 90s.
It will be muggy today but presence of a north/northeast flow for
much of the day will keep dewpoints from getting out of control.

&&

.SHORT TERM /Tonight through Saturday Night/...
Issued at 323 AM EDT Thu Jun 28 2018

Forecast challenges focus squarely on the arrival of what is likely
to be the most uncomfortable conditions of the summer so far through
the period.

Upper ridging centered over the southern Plains this morning will
expand into the Ohio Valley and lower Great Lakes into the weekend
with mid level heights likely to top out at or just above 595dam.
With the frontal boundary currently over the lower Ohio Valley
poised to surge back north through the region Friday into
Saturday...the floodgates will be opened for the highest dewpoint
air yet this year to advect into the region. Dewpoints are in the
mid and upper 70s located just south of the frontal boundary from
eastern Kansas into western Tennessee and those numbers seem quite
reasonable as the front shifts back north into the region by Friday
afternoon and into Saturday. The result will be a truly oppressive
feel to the airmass for Friday and Saturday.

With the core of the ridge building into the area...little to no
forcing aloft...paltry BL shear and model soundings showing the
capping inversion persisting...any threat for convection appears low
at this point. That being said...with such strong diurnal heating
both Friday and Saturday...instability levels approaching 5000 J/KG
exist above the inversion. If any of this instability can be
tapped...isolated slow moving strong storms would likely explode
focused during the afternoon and evenings. The amount of instability
present alone would suggest any storm would be a prolific
lightning producer and would be capable of locally heavy rainfall.

There appears to be a narrow window for convective development on
Friday as a weakness develops over the area on the east side of the
expanding ridge core. The NAMNest is the only model that appears to
be capturing this idea...pulling a convective complex southeast into
the region around the periphery of the ridge. Confidence in this
occurring is very low to say the least considering the presence of
such a strong cap...but it is a possibility to keep in the back of
our minds going forward. The other spot where a few storms may
develop is Saturday afternoon as the cap is actually weaker...but
virtually no forcing aloft exists under the ridge core. Will
continue with a dry forecast at this time with low confidence in any
potential convection development.

Temps...the story will be the heat and humidity through the period
as 850mb temps rise to 21-23C by Saturday with 925mb temps at 27-
28C. This is fully supportive of widespread 90s both Friday and
Saturday...with mid 90s likely present across the board Saturday.
Dewpoints in the mid to possibly upper 70s will produce max heat
indices over 100 both days and potentially pushing 110 on Saturday
afternoon. Headlines in the form of a Heat Advisory are virtually
certain to be needed for Friday and especially Saturday. With
primary impacts still 24+ hours away...will hold off on any issuance
this morning and focus via the HWO and an SPS. Lows will likely not
fall any lower than the mid 70s over the weekend.

&&

.LONG TERM /Sunday through Wednesday/...
Issued at 238 AM EDT Thu Jun 28 2018

Ensembles in good agreement with the overall weather pattern
during this period. Short wave troughing moving through the Great
Lakes early next week will temporarily suppress the heat ridge
somewhat, before it builds back into the area by the middle of
next week.

Ensembles indicate a front will approach the area from the
northwest on Sunday, eventually settling across the area and
gradually weakening with time.

Long range operational models suggest the local area will reside
along the eastern edge of the mid level cap during this period.
Not sure cap will be strong enough to suppress potential for
convective complexes given the high instability progged. Will
keep chance PoPs going throughout the extended.

&&

.AVIATION /Discussion for the 28/1800Z TAF Issuance/...

Issued at 119 PM EDT Thu Jun 28 2018

VFR conditions are expected to persist through the TAF period.
Diurnal CU at around 3500 feet are over most of the terminals at
varying coverages. CU is expected to dissipate by 2300Z today.
Surface winds remain light today and then push in from the south
and southeast after 1200Z Friday at up to 8 to 10 knots.

A couple model solutions depict the possibility for convection
pushing near or into the western portions of central Indiana
Friday morning after 29/0900Z as an upper level disturbance is
forecast to ride the top of the upper ridge building over the area
and push south-southeast into the area. Confidence in this
scenario occurring is not currently very high...thus, it has been
left out of this round of TAFs.
