.KEY MESSAGES...
- *HEAT ADVISORY* continues through late day Friday
- Heat indices up to 100-107 degrees and low temperatures near or
above 74 degrees through Friday
- Scattered daily afternoon showers/t-storms, isolated strong to
severe wind gusts are possible as well as localized flooding
&&
.SHORT TERM (This evening through Friday)...
Issued at 254 PM EDT Thu Jun 26 2025
Showers and thunderstorms have developed today, largely from Indy
eastward. Cumulus developed initially across the entire area fairly
evenly...but over time only the eastern half grew into storms. The
western half, however, has diminished in coverage and height.
Low-level water vapor reveals a pocket of dry air located over the
western portion of the CWA. What likely happened is that cumulus
fired up upon reaching convective temps...but as the boundary
layer deepened, some of that dry air mixed down allowing
convective processes to diminish over our western counties.
Convection is therefore likely to be confined mainly to the eastern
portions of the area. Some of the storms have strengthened nicely,
with a few weak downburst signatures shown on the KIND radar.
Storm activity may continue to pose a downburst threat as it
travels east into Ohio. Steep low-level lapse rates and decent
storm top flow support this idea. Shower and storm activity should
rapidly diminish after sunset as diurnal heating is lost.
Showers and thunderstorms return on Friday as a weak cold front
approaches the area. Model soundings show greater moisture in the
column compared to today, with similarly weak flow aloft. Lapse
rates are steep in the low-levels but modest to weak aloft. CAPE
profiles are tall with ELs over 12km and values around 2000-3000
J/Kg. Despite weak flow, frontal forcing combined with the
buoyant atmosphere should allow for convection by the afternoon.
Severe weather is not expected, but an isolated downburst capable
of strong/marginally severe wind gusts cannot be ruled out.
Temperatures...heat advisory continues into Friday with yet another
hot and humid day expected. Lows in the mid 70s should provide
little nocturnal relief and exacerbate heat-related health
effects.
&&
.LONG TERM (Friday night through Thursday)...
Issued at 254 PM EDT Thu Jun 26 2025
A Rex Block over the SE CONUS has kept a strong ridge over the Ohio
Valley, resulting in an extended heat wave for central Indiana. The
Rex Block creating the extended heat wave over the Ohio Valley will
begin to break down tomorrow through the weekend, mostly related to
the arrival of a weak and slow moving low level shortwave over the
Great Lakes region. As the shortwave nears late Friday into Saturday
an increase in lift will likely allow for continued scattered to
numerous coverage of showers and thunderstorms Friday night into
Saturday. Given the presence of the shortwave, there is likely to
be some near surface high pressure building in from the NW on
Saturday, with a push of slightly drier air along with its arrival.
This will slowly decrease precipitation chances throughout the day
Saturday from NW to SE. By Sunday, this dry air mass should
encompass all of central Indiana, significantly reducing PoPs. With
greater cloud coverage, and the arrival of a slightly drier air mass
on Saturday, it is likely that temperatures will be more limited,
with highs slightly lower; in the upper 80s.
Even with the shortwave present, upper level forcing will be very
weak, with marginal shear through the lowest 6km. This should limit
storm organization, with any severe weather expected to be very
isolated.
The ridge will continue to break down early next weak, with more
seasonal temperatures expected Monday through Wednesday (mid 80s).
Low to mid level moisture is expected to stick around for early next
week as well, leading to daily thunderstorm chances once convective
temperatures are reached. Generally, synoptic dynamics are expected
to remain weak, leading to the continued expectation of unorganized
thunderstorms, but model uncertainty is high on any low level
features for a more mesoscale specific threat.

.AVIATION (18Z TAF Issuance)...
Issued at 131 PM EDT Thu Jun 26 2025
Impacts:
- Chance for afternoon showers and thunderstorms
Discussion:
VFR conditions expected through the TAF period, except during
showers or thunderstorms.
Showers or thunderstorms are expected to be isolated in nature, and
the likelihood of any particular terminal experiencing one is
low...so they will not be explicitly shown in the TAFs for now.
Winds will retain a southwesterly component today around 10kt with
perhaps a gust to 20kt. Winds die down and become a bit more
southerly overnight, before picking up and returning to
southwesterly on Friday.
Showers and thunderstorms are once again possible on Friday but
mainly near and after the end of the TAF period.
&&
.IND WATCHES/WARNINGS/ADVISORIES...
Heat Advisory until 8 PM EDT Friday for INZ021-028>031-035>049-
051>057-060>065-067>072.
