KEY MESSAGES

- Scattered showers and thunderstorms today

- Isolated strong storms are possible, with gusty winds and hail, mainly northeast

- Rain chances again Friday into Saturday and early next week

- Above normal temperatures through early next week

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 (12Z TAF Issuance)

Issued at 653 AM EDT Wed Apr 22 2026

Impacts:

- Isolated showers near KBMG early - Scattered convection possible this afternoon and evening, mainly KLAF/KIND - Wind gusts around 20kt this afternoon

Discussion:

Most convection has ended, but a few showers may linger in the KBMG area this morning. More scattered convection may develop this afternoon and linger into the evening, mainly around the northern sites.

Confidence has lowered in the MVFR ceilings this morning, so just allowed low VFR ceilings to develop. Still can't rule out MVFR completely this morning though. Otherwise, VFR conditions are expected outside of any convection.

IND WATCHES/WARNINGS/ADVISORIES

None.
