The declaration was extended to allow the state to continue using certain resources to help local governments clear roads and deal with other storm-related issues, Deal said in a statement.
The governor and Director of the Georgia Emergency Management Agency, Charley English, have taken responsibility for poor planning leading up to the storm.
"We did not make preparations early enough," Deal said at a news conference. "I'm not going to look for a scapegoat. I am the governor. The buck stops with me."
Deal added that state agencies would do internal reviews and come up with revised protocols to respond to severe weather forecasts.
Temperatures in the region were expected to reach the low 50s on Friday, which should help officials clear ice accumulations from local roads. Temperatures are expected to remain well above freezing and reach the low 60s Sunday, according to the National Weather Service.
