The heat wave settling over the Midwest is a byproduct of what’s left of Tropical Storm Barry, according to the National Weather Service.

NWS Meteorologist Mike Ryan says Hoosiers in central and southern parts of the state can expect high temperatures combined with high humidity through Sunday.

He says the tropical humidity is what makes this heat wave so unusual.

"It’s amplifying, basically, how it feels outside with the temperatures that we’re expecting in the afternoon," Ryan says.

National Weather Service meteorologists say the cold snap heading to Indiana beginning Tuesday night is going to hang around for at least the next ten days.

"Teens and twenties at night and thirties for highs," says National Weather Service meteorologist Mike Ryan. "Still looks like potential maybe for some light snow on Sunday and then also some maybe some later next week. But again, that being out a few days -- need to fine-tune that."

Ryan says the system is funneling cold air down from Canada over much of the eastern U.S.
