.FORECAST UPDATE...
Issued at 110 AM EDT Fri Jun 12 2026

Severe threat continues to lower with main outflow boundary now
south of much of the area. Still keeping an eye on storms moving
east from Sullivan County. Odds remain low for severe, but will
keep the severe watch going from there east just in case. With some
training of storms, will continue to monitor for flooding concerns.

Otherwise, coverage of rain will gradually diminish as main forcing
exits south.

.DISCUSSION (This evening through Thursday)...
Issued at 330 PM EDT Thu Jun 11 2026

Heat and humidity continue today with heat indices near 100 degrees
this afternoon. Behind a cold front, which will bring a line of
showers and thunderstorms tonight, some relief to the hot conditions
will arrive.

Tonight`s round of convection will also be spurred on by a wave
ejecting from the broader trough aloft. Recent CAM runs continue to
slow the line down despite lagging slightly from where storms are
actively ongoing to our northwest. Still can`t rule out the line
slowing some between now and tonight, but will keep with the
arrival timing between 8pm and 10pm rather than later. Guidance
continues to show a bit more energy in the atmosphere which could
lead to severe thunderstorms at times, especially northwestern
portions of central Indiana. Like last night, storms will likely
become outflow dominant as they head southeast away from the best
forcing and shear, but damaging wind gusts will again be the main
threat as storms decay over our forecast area. Localized flooding
may also be a concern in heavier storms. Storms are expected to
weaken by around 2am followed by rain and the associated cold
front exiting to the SE by tomorrow morning.

Behind the front, central Indiana will see some relief for the
weekend. Another system will likely bring additional showers and
storms Saturday night to Sunday morning followed by further heat and
humidity relief going into the start of next week.

.AVIATION (06Z TAF Issuance)...
Issued at 110 AM EDT Fri Jun 12 2026

Impacts:

- Showers and thunderstorms ending early
- Winds become northwest overnight
- Potential for gusts of 15-20kt Friday afternoon

Discussion:

Convection will gradually diminish from north to south early in the
period. Included TEMPOs and VCSH as needed. KBMG has the highest
chance for a thunderstorm. MVFR and worse conditions are possible in
a thunderstorm.

Behind the convection there may be a brief period of MVFR ceilings.
Otherwise outside of convection VFR conditions are expected through
Friday. Winds may become gusty for a period Friday afternoon, but
confidence isn`t high enough to add at the moment.
