A cold front will bring rain and thunderstorms back to the Miami Valley by Friday afternoon. Some of those storms could bring a threat of damaging winds, hail and heavy rainfall.

After breaking a daily rainfall record in Dayton on Thursday for the fifth time this year, more storms will threaten the Miami Valley today.

Our Storm Center 7 meteorologists are monitoring an approaching cold front that is expected to arrive in Ohio on this afternoon. Thunderstorms are expected to develop along the front and strengthen as the move into the Miami Valley during the peak heating of the day Friday.

Chief Meteorologist Eric Elwell said his main concern from the strongest storms will be for damaging winds and large hail. 

An isolated tornado cannot be ruled out as the cold front moves by, he said, noting, "We'll also have to watch the threat for flooding."

Elwell said that after some areas in the region took on nearly 3 inches of rain Thursday, it won't take much additional rain to create some problems. 

Storms are expected to move through fairly quickly, which should help keep flooding to a minimum, Elwell said. 

The front is expected to usher in cooler and less humid air tonight and into the weekend.

UPDATE @ 3:30 p.m.:

The mystery of what caused loud booms Saturday night in Middletown has been solved.  

Large rainfall during the removal of hot slag from the AK Steel plant caused “a louder than usual noise,” said Douglas Huffnagel from Stein.

Slag is a byproduct of the steelmaking process and can be extremely hot. When moisture hits slag, it can cause a loud noise.

Huffnagel said no one was injured and no equipment was damaged. 

For more than 60 years Stein Inc. has been providing slag processing and steel mill services, according to its website.

UPDATE @ 1 a.m.

There were numerous reports of several loud explosions Saturday night, but Middletown police said on social media they were not aware of any explosions and had not responded to one.

Middletown residents reported the blasts were believed to have come from AK Steel Corp., but the company told Middletown police they were fine.

EARLIER

There have been numerous reports of several loud explosions Saturday night at AK Steel Corp.
