"Severe thunderstorms with damaging wind gusts, large hail and possibly a few tornadoes are expected," said the weather service.

With radar showing green and yellow trouble marching this way from the west, Roxbury High School officials are preparing, said district spokeswoman Ameerah Palacios.

"Roxbury High School administrators are closely watching the weather today in anticipation of graduation ceremonies," she said in an email. "We are hoping to be able to have graduation outside. However, we are set up to hold graduation in the gymnasium as a backup."

Video of the big event will be broadcast over the Internet for those unable to attend. The "livestreaming" will begin at 5 p.m. on, said Palacios.

The weather service said the worst of the weather is expected to arrive right about the time the high school seniors are getting their diplomas. "Severe storms are possible across the region, primarily in the afternoon to early evening hours just ahead of a cold front that is due to arrive," said the forecasters. "The primary hazard will be strong winds, but some hail is possible as well."

Before all that happens, "dangerously hot conditions will be possible" across the area, said the weather service. It urged people to "stay tuned" to
