Central Indiana could see severe thunderstorms capable of isolated tornadoes overnight

Indianapolis' weather forecast for Friday, Dec. 10.

A strong weather system, unusual for winter, will move through Central Indiana on Friday and carries a chance of severe thunderstorms capable of producing an isolated tornado.

After a bout of dense morning fog settling throughout much of the region, delaying the start of some school systems' classes, the National Weather Service said conditions will shift tonight to a slight severe thunderstorm risk beginning about 9 p.m.

Damaging winds that could reach 60 mph pose the biggest threat, the weather service said.

Hail and an isolated tornado churned up from the strong wind, meteorologists said, are also possibilities.

“This is a really complex system,” said NWS Meteorologist David Beachler, calling it an “anomalous” event. “This type of event during the winter months is not normal, but they do occur and we try to alert the public as much as we can.”

Beachler said this type of pop-up severe weather hazard during the winter months typically comes a day or two after a stint of cold temperatures that are followed by warmer weather.

He said Central Indiana residents should continue to check on forecasts through the evening, especially because the storms are expected to occur overnight.

Meteorologists said the storms will dissipate by 8-9 p.m. Saturday. Beachler said the area will see a milder stretch of weather for the next several days.
