Violent overnight thunderstorms turned deadly in northeast Georgia, where a tree fell on an elderly Banks County man's mobile home, crushing him as he lay in his bed.

The tree toppled onto the unidentified man's home near Homer shortly before 10 p.m. Tuesday, authorities said.

Elsewhere, storms uprooted a large pine near Lawrenceville, sending it crashing onto a home on Chandler Road, Gwinnett fire Capt. Tommy Rutledge said. He said a woman in the house was treated at the scene for minor injuries, but several small children escaped injury.

Lightning from the storms sparked house fires in Gwinnett and north Fulton counties. No injuries were reported in the fires.

The risk of afternoon and evening thunderstorms remains in the forecast for metro Atlanta through the weekend, the National Weather Service said.

The chance of storms is 20 percent tonight, 50 percent on Thursday and 20 percent Friday, forecasters said. Highs will be in the mid-80s Thursday and Friday.

The outlook for the weekend calls for a 40 percent chance of showers and thunderstorms Saturday and Sunday, with highs each day near 90 degrees.
