.DISCUSSION (Today through Wednesday)...
Issued at 305 AM EDT Thu Jun 11 2026

The pattern aloft is characterized by ridging over the eastern US
and into Canada with troughing over the western US and northern
Plains. Troughing has been gradually pushing eastward over the past
few days. Embedded waves have ejected from the trough, bringing
round after round of severe weather across the Plains and Midwest.
We are seeing the remnants of some of these storms right now, as an
MCS enters Indiana from the NW as of this writing. Weakening is
expected as the system outruns the best synoptic forcing and shear.
Nevertheless, thunderstorms with gusty wind are possible as far as
Indianapolis through the morning hours.

Once the rain dissipates, we`ll be left with clearing skies. High
temperatures today will be near 90, with dew points into the low to
mid 70s. Max heat indices are forecasted to be between 100 and 105,
which may lead to enhanced heat risk for vulnerable populations.

After a mostly dry day today, another round of convection associated
with a wave ejecting from the broader trough arrives tonight.
Guidance shows a bit more energy in the atmosphere which could lead
to severe thunderstorms at times, especially northwestern portions
of central Indiana. Like this past evening, storms likely become
outflow dominant as they head southeast away from the best forcing
and shear. Strong to severe wind gusts and localized flooding are
the primary hazards with the highest threat in our NW.

Once that system and its cold front pass through late Thursday
night, a transition to a cooler and less active pattern appears
likely. Broad troughing aloft looks to persist this weekend and
into next week, with near-average temperatures (highs near 80 and
lows near 60) along with lower humidity. A few weak waves embedded
within the broader trough may bring rain chances on Sunday and then
again on Tuesday or Wednesday of next week. These are subtle
features and are hard to pin point this far out. So we will maintain
only chance PoPs next week until the signal become clearer.

.AVIATION (12Z TAF Issuance)...
Issued at 640 AM EDT Thu Jun 11 2026

Impacts:

- Rain ending this morning.

- Gusty SW winds from 20-25 kts during the afternoon.

- Thunderstorms arrive this evening, approaching KIND during
  freighter inbounds.

- LLWS between 40-45kt tonight.

Discussion:

Showers and thunderstorms persist over central Indiana, with light
rain at all terminals. Rain will come to an end between 12-13z with
VFR conditions expected for the remainder of the day.

Increasing SW wind gusts of 20-25 kts by afternoon are expected.

Another convective line will move across central Indiana Thursday
night possibly affecting KIND during the middle part of the
freighter inbounds. A prob30 group was included for all terminals
given the potential for strong thunderstorms with MVFR or lower
conditions.

After the storms end tonight, a cold front will cross the area
causing winds to become west-northwesterly.
