.DISCUSSION (Today through Friday)...
Issued at 336 AM EDT Sat Jun 6 2026

More active pattern for central Indiana to begin today, with showers
and at least a few thunderstorms favored into the middle of next
week...with the return to generally dry conditions likely allowing
widespread low 90s and potentially 100F+ heat indices.  Generally
disturbed pattern to exhibit overly diurnally-driven showers/TRWs,
with more widespread rain coverage focused this afternoon/tonight
across the CWA`s northern half...and then for all zones within the
Monday-Tuesday timeframe.

Northern wave crossing the Great Lakes today will drag the tail of
its cold front across the northern Midwest...setting the stage for
showers and t-storms early this morning along our northern tier
where southwest breezes will combine with lift from this approaching
boundary.  Cannot rule out a few stronger cells, although very low
confidence in any damaging wind threat early today.  Better shot at
marginally strong/severe storms arrives this afternoon/evening and
possibly into portions of the overnight...as the next wave to our
west helps direct ribbon of increasing Gulf moisture into the
stationary boundary.  Focus will remain over region`s northern half,
albeit now with opportunities for a few severe storms with winds and
hail the only modes of concern, with the threat slowly waning during
the evening.  Perhaps greater overall concern will be localized
flash flooding as heavier rain may train west to east over same
areas, with chances for flooding increasing through PM hours over
far northern zones.

Turning to next week, a weakly forced and slowly-progressing short
wave...nestled on the west side of an eastern-NA upper ridge... will
drift from the central US today, to Indiana Monday night.  This
feature will combine with broad but weak surface ridging to our east
to promote slow increase of Gulf moisture northward into the
Midwest, with precipitable water values over 1.75 inches from dawn
Sunday into the mid-week.  Unsettled and humid set-up will often
host considerable cloudiness, as readings range from a muggy 70F or
so to somewhere in the 80s...with temperatures slowly trending
upward into the mid-week.  Often isolated to scattered showers and a
few rumbles of thunder will surround a 24-hour period of more
widespread showers and scattered thunder within Monday-Tuesday when
the short wave slowly trucks east across Indiana.  Too early to
decipher if any severe storms will occur, but at least isolated
strong cells will be on the table.

Turning hot at the end of the period amid southwest gusts around
10-20 mph both Wednesday and Thursday under decreasing clouds.
Highs will most likely reach the low 90s for Thursday and Friday
for most locations, while oppressive dewpoints still in the 70-75F
realm boost heat Indices potentially to 95-105 degrees during
afternoons.

.AVIATION (12Z TAF Issuance)...
Issued at 704 AM EDT Sat Jun 6 2026

Impacts:

- Scattered -SHRA/TSRA to impact KLAF this morning
- Stronger TSRA to trend from KLAF to KIND within 20Z-01Z, with less
   intense convection lingering through evening around KLAF/KIND
- Peak gusts outside storms to around 17-21KT today
- MVFR ceilings/visibility possible in stronger convection, as well
   at KLAF/KIND by evening

Discussion:

VFR is expected through the majority of the TAF period near central
Indiana terminals, with MVFR possible at times, mainly at KLAF/KIND.
This more active TAF period as southwest flow boosts Gulf moisture
into the region...will see morning convection likely impacting KLAF
and then more organized SHRA/TSRA from mid-afternoon into the
evening from KLAF to KIND...with very low confidence in any late day
convection reaching KHUF.

+RA and gusts in excess of 40KT are possible in/near stronger cells
within the 20Z-01Z period at KLAF/KIND.  Dragging cold front across
northern IN will stall tonight, favoring continuation of non-severe
-SHRA/few TSRA near mainly KLAF/KIND.  VCSH possible at KHUF this
evening, but confidence too low to include in TAF.

Southwest winds will stay breezy today, sustained at 7-14KT, gusting
up to 17-21KT through much of the day.  Winds this evening, outside
of convection, to diminish to under 7KT...with lighter flow
maintained into Sunday.
