After record-high temperature day, storms threaten Indy area. What's next in the forecast

Mother Nature delivered her Greatest Hits to the Indianapolis area this weekend.

Saturday, we chucked our winter boots for flip flops and enjoyed a sunny, breezy summer's day, which broke a decades-old high temperature record.

After midnight, the rain joined the wind. Around 3 a.m., National Weather Service tornado sirens and phone alerts startled Hamilton County residents awake with the call to seek shelter.

And after a calm Sunday, the threat may return Sunday night.

The NWS has not confirmed any tornado touchdowns, nor are there strong enough signs of any for the local office to send out surveyors, meteorologist Randy Bowers said.

The tornado warning started with Carmel, Noblesville and Westfield at 2:55 a.m., as a fast-moving line of severe thunderstorms approached with heavy wind gusts. Within minutes, the warning moved northeast to Madison and Delaware counties, including Muncie, Anderson and Yorktown.

While the radar showed some signs of rotation, most of the wind looked straight, Bowers said. Wind gusts clocked in up to 60 mph.

"We may have gotten away with some straight line winds," he said.

He said there were some reports of downed tree limbs and power lines, but none of serious damage.

Indianapolis did break a temperature record Saturday.

Saturday's high of 77 degrees beat the old record for March 5 that was set in 1956 and tied in 1983 — 75 degrees, according to the NWS.

Temperatures are falling to the mid 50s through the day Sunday, and some wind gusts are sticking around.

Then Sunday night after midnight, another line of severe thunderstorms is expected south of I-70, along with the threat of isolated tornadoes or damaging winds.

Then a cold front will move through the area Monday, dropping temperatures back to familiar territory overnight: below freezing.
