.SHORT TERM (Today and tonight)...
Issued at 215 AM EDT Tue Jun 10 2025

Early This Morning...

Quiet weather will continue as a surface cold front has moved
southeast of central Indiana. There will be some passing mid clouds,
especially south, as they traverse through an upper trough.

Today...

The area will remain in northwest flow aloft on the back side of an
upper trough, keeping some cooler air aloft over the region. This
will allow scattered cumulus to pop up today, becoming broken at
times.

In addition, another round of elevated wildfire smoke will move in.
This will keep skies hazier than normal.

The result of the above will be partly cloudy conditions at times
throughout the day.

At the surface, high pressure will be in control.

The available sunshine today will help temperatures peak in the
middle and upper 70s.

Tonight...

A quiet night is expected with high pressure remaining the dominant
influence. Cumulus will dissipate by early evening, just leaving
some passing elevated smoke at times.

Lows will generally be in the middle and upper 50s.

&&

.LONG TERM (Wednesday through Monday)...
Issued at 215 AM EDT Tue Jun 10 2025

Split flow will continue through much of the period, with the jet
stream staying north of central Indiana. An upper level trough will
eventually move northeast into the area, which will keep rain
chances around.

Wednesday into Thursday...

Wednesday will be quiet with upper ridging in place. Warmer air
moving in will bring highs in the mid 80s.

On Thursday, the northern stream will bring a cold front into
northern Indiana. Most of the chances for rain should remain north
of the forecast area, but can`t absolutely rule out an isolated
shower or storm reaching the northern forecast area. Will have some
slight chance PoPs Thursday afternoon north, but with low confidence.

Friday and beyond...

Uncertainty remains higher than normal through the remainder of the
long term period. As noted above, an upper trough will move from the
south central part of the country northeast into the area. Models
are not consistent with the timing of this though, which leads to
the uncertainty.

Before the trough arrives, the old surface front will remain in
northern Indiana. Southerly flow will bring in moisture, and with
high temperatures in the 80s, instability will thus build in the
afternoons. Scattered showers and storms will be possible before the
trough arrives.

Will thus have PoPs throughout the long term period. At the moment,
this weekend looks to have the highest chances for rain, but that
could change.

Even if the trough moves through quicker, zonal flow could set up,
bringing occasional rounds of forcing which would bring periodic
chances for rain regardless.

Highs in the 80s with lows in the 60s will be the rule through the
long term.
