Area Forecast Discussion
National Weather Service Indianapolis IN
302 AM EDT Thu Jun 18 2026

- Better chances for rain return Sunday into Monday

- Below normal temperatures will continue for much of the period

&&

.DISCUSSION (Today through Wednesday)...
Issued at 301 AM EDT Thu Jun 18 2026

Early This Morning...

Convection will continue across the southern forecast area where
instability remains but will be slowly weakening. Severe storm
threat should end before 08Z as the leading edge of the convection
sinks south of central Indiana, limiting the inflow of storms to the
north. Threat will transition to flooding with repeated rounds of
storms moving through. Current thoughts are that by the end of the
Flood Watch valid time, most areas will have transitioned to ongoing
flood advisories/warnings, so will let it expire.

Today...

By 12Z rain should be south of the forecast area, so will start the
day off dry. However, some additional upper forcing will move
through this afternoon and could generate some sprinkles or a few
showers. Will have some slight chance PoPs across portions of the
southern half or so of the forecast area this afternoon.

Highs will be in the lower to middle 70s north to around 80 south.
There is some uncertainty with these numbers as cloud cover with the
afternoon sprinkles/showers may keep readings down.

Tonight and Friday...

High pressure will build in and bring quiet weather to the area
during this period. Below normal temperatures will continue with
lows in the 50s tonight and highs mainly in the 70s Friday.

Saturday...

A weak system in northwest flow will bring some forcing to the area
on Saturday. However, moisture will be limited. Will have some
slight chance PoPs with this system. Below normal readings in the
middle 70s to around 80 will continue for high temperatures.

Sunday and Monday...

An upper level wave and surface low pressure system will move
through the area during this time. There remains some questions in
timing of these, but for now it appears that the highest PoPs will
be Sunday night. This system may be able to tap into some moisture
and bring near an inch of rain.

Tuesday and beyond...

High pressure will try to keep the area dry mid-week next week, but
some upper energy may try to squeeze out a few showers around
Wednesday. Temperatures will continue to be below normal for much of
the area.
