.DISCUSSION (Today through Tuesday)...
Issued at 249 AM EDT Wed Apr 22 2026

Early This Morning...

Some upper energy is interacting with elevated moisture/instability
and producing scattered showers and thunderstorms across central
Indiana early this morning. A few of the storms are pulsing high
enough for perhaps some gusty winds/small hail.

This should continue through the predawn hours, but the focus should
gradually shift southeast as the upper energy moves southeast. Will
continue with PoPs no higher than chance category.

Today and Tonight...

A few showers or storms may linger into the daylight morning hours
across mainly the southeast forecast area as the upper energy exits.
There should then be a lull before more scattered convection
develops this afternoon. Additional upper energy plus some influence
from a cold front north of the area will help these develop. With
upper ridging trying to nudge into the southwest forecast area, will
confine PoPs to the northeast half of the area, which is also closer
to the front to the north.

Instability and shear look to be enough for an isolated strong or
severe storm, but these should be mostly confined to north and east
of central Indiana where the better parameters will exist.

Temperatures will peak in the mid to upper 70s. However, if clouds
are less numerous, then temperatures might get closer to 80,
especially southwest.

Convection should end by mid-evening with loss of instability and
with the ridging moving in. Lows will be in the 50s.

Thursday...

Upper ridging will provide quiet and warm weather Thursday, with
highs around 80.

Friday and beyond...

An upper trough rotating around an upper high across southern Canada
will bring forcing along with a surface cold front on Friday.
Moisture will flow north from the Gulf into this system, so will go
high PoPs on Friday.

Much of Saturday and all of Sunday should be dry with high pressure
building in.

Early next week, a stronger upper trough will move into the area,
bringing a low pressure system and another cold front. This will
bring more rain to the area. Present indications that Monday will
have the highest chances for rain.

Only slightly cooler air will be behind the first front, so above
normal temperatures will continue into the weekend. Cooler, but
still close to normal, temperatures will return after Monday`s
front.

.AVIATION (06Z TAF Issuance)...
Issued at 107 AM EDT Wed Apr 22 2026

Impacts:

- Scattered showers and some thunderstorms at times through
  Wednesday
- LLWS continues through early morning
- MVFR ceilings developing Wednesday morning
- Wind gusts around 20kt Wednesday afternoon

Discussion:

An upper disturbance will continue to generate scattered showers and
a few thunderstorms overnight, with coverage gradually diminishing
by late in the overnight. More scattered convection may develop
Wednesday afternoon, mainly around the northern sites.

MVFR ceilings will develop by 12Z or so at the northern sites as the
atmosphere moistens up some. This will lift/break up by afternoon.
