Area Forecast Discussion
National Weather Service Indianapolis IN
114 PM EDT Wed Aug 19 2026

.KEY MESSAGES...

- Flood Watch in effect from 2PM Today through 8AM Thursday across
  the northern half of central IN with localized flash flooding
  possible

- Scattered to numerous showers and storms are expected this
  afternoon into tonight, isolated severe storms are possible

- Generally drier late this week through early next week, but there
  is a chance for showers and storms late Friday into Saturday

&&

.FORECAST UPDATE...
Issued at 1141 AM EDT Wed Aug 19 2026

Isolated light showers are tracking across parts of south-central
Indiana. Later today, another round of showers and storms are
expected to move in from the northwest which could produce a swath
of 1-2" of rain from this afternoon through tomorrow morning. The
question is still where exactly the highest rain amounts fall, but
north of Indy is where models continue to highlight. If enough rain
falls within the White River basin, points along the river within
Indy could back into Action Stage with an outside chance of a brief
return to minor flooding by this weekend possible.

Outside of the flooding, some isolated areas of severe weather will
be possible this afternoon to evening with damaging winds and hail
the main threats. Given how saturated the ground is across the
forecast area, even sub-severe winds could lead to tree damage.

Made a few adjustments to the PoPs to better match ongoing isolated
showers and minor tweaks to the late day PoPs.

&&

.DISCUSSION (This afternoon through Tuesday)...
Issued at 618 AM EDT Wed Aug 19 2026

Today through tonight...

Patchy fog will be possible through daybreak as winds remain very
light across central Indiana. Any fog that develops should quickly
mix out in typical diurnal fashion. Regional radar mosaic depicts an
MCS currently moving across eastern MO and western IL. This system
will continue to propagate southeastward along an instability
gradient, keeping precipitation mostly confined to southwest
portions of the forecast area through the morning. Isolated
thunderstorms cannot be ruled out given weak elevated instability.

Greater chances for convection are expected this afternoon into
tonight as a mid-upper level wave pushes across the region. At the
surface, a weak west to east oriented cold front should gradually
push south providing low-level convergence. These features along
with daytime heating over an abundantly moist environment supports
the potential for scattered to numerous showers and thunderstorms.
Convection could continue well into the overnight, but expect
generally decreasing coverage late tonight as the the strongest
forcing shifts east

Deep-layer wind shear is supportive for organized convection, but
there remains some uncertainty on the degree of destabilization
later today which limits confidence on the overall severe threat.
Isolated damaging wind gusts or severe hail appear possible if
sufficient destabilization occurs as favorable deep-layer wind shear
supports the potential for multicell line segments and possibly even
a few transient supercells.

The greater concern will be localized flash flooding given soils
remain very saturated from recent rainfall. Model guidance continues
to suggest the potential for training storms with the west to east
oriented cold front slowly pushing south. Warm rain processes and
PWATs around or over 2 inches will also promote efficient rainfall
rates. Latest CAMs generally suggest the potential for 1 to 3 inches
of rain where training occurs. A Flood Watch is in effect from 2 PM
today through 8 AM Thursday across the northern half of central
Indiana where training storms over saturated soils appears most
likely. Additional fog development is possible late tonight once
convection dissipates.

Thursday through early next week...

Surface high pressure building in will provide mostly quiet weather
conditions Thursday and Friday. A few upper level disturbance will
move in late Friday into Saturday supporting at least low rain
chances with sufficient moisture advecting into central Indiana.
Long range guidance generally depicts surface high pressure building
in once again late weekend into early next week providing mundane
weather conditions. Expect temperatures to remain slightly below
normal during the period.

.AVIATION (18Z TAF Issuance)...
Issued at 114 PM EDT Wed Aug 19 2026

Impacts:

- Scattered to numerous showers/storms this afternoon/tonight

- Fog/low ceilings likely late tonight into Thursday morning

Discussion:

Convection is developing across the area and all sites will likely
see impacts at some point this afternoon into tonight. Will carry a
combination of PROB30 and TEMPO groups at all sites. Fluctuating
restrictions will be likely during convective impacts at all sites.

Late tonight as the cold front passes through the area, low clouds
and fog are likely to develop, with IFR or worse conditions
possible.

Winds will be southwesterly this afternoon, becoming light and
variable to calm overnight, then northerly late in the period.
