RTV6 Meteorologist Todd Klaassen said Hoosiers could expect 103 degrees by midday.

Marion County’s burn ban includes any open burning, comfort fires, camp fires or agricultural burning.

Indianapolis Fire Department officials said the ban does not apply to outdoor grilling or fireworks, but authorities are discouraging those activities during the extreme heat.

"The state will not allow us to ban fireworks between the end of June and into July, so what we're saying with fireworks is we're hoping that people will go to (fireworks shows),” said IFD Battalion Chief Fred Purvine.

The fine for violating a burn ban with an open fire is $2,500, RTV6’s Julie Pursley reported.

Meanwhile, the Salvation Army is scheduled to open two Indy cooling stations to help Hoosiers beat the heat.

The Eagle Creek Salvation Army location in the 4400 block of North High School Road will be open Thursday through Sunday from 10 a.m. to 6 p.m.

The Fountain Square Salvation Army at 1337 Shelby Street will also be open Thursday through Sunday from 10 a.m. to 6 p.m.
