ATLANTA -- Wintry weather blew into Georgia on Tuesday, dumping several inches of snow in the northern mountains but leaving no significant accumulation in Atlanta.

School districts canceled classes and airlines canceled flights in anticipation of snowy conditions, and a winter storm warning lingered into the afternoon.

Some school districts are struggling to meet the required 180 classroom days this school year because so many days have been lost because of bad weather. That includes days missed because of flooding last September.

Tuesday's snow, combined with freezing overnight temperatures, could have caused problems on Wednesday, however strong winds and higher then expected temperatures diminished the chances for widespread icing.

Georgia Department of Transportation crews were dispatched across the Metro around 3 a.m. Wednesday as a precaution, spreading sand and gravel on some bridges and overpasses.

"We treated I-75 from 10th to 17th streets as well as some of the ramps on I-20," said Luke Carman, foreman at the Cheshire Bridge Street GDOT location.

While there were a few weather-related car crashes, Georgia State Patrol reported a routine morning.

A Chevy Tahoe flipped on its side in a ditch in Alpharetta just before 8 a.m. on Northpoint Parkway near Kimball Bridge Road.

Firefighters had to use a crowbar to pry open the back and help the driver out to safety.

Enoch Shoates said the roads are pretty clear today, he will drive cautiously anyway.

"I'm driving under 40. Trust me. Someone may fishtail. I don't mess around, trust me," said Shoates.

In the pre-dawn darkness, a tow truck had to clean up the mess after a three vehicle accident on Georgia 400 shut down all three southbound lanes.

GDOT said one person was injured and traffic was backed up for 20 minutes.

Tuesday's snowfall was the region's fourth "measurable snowfall" of the winter. The metro area generally gets one to two measurable snowfalls per year, meteorologists said.

How much snow you got Tuesday depended on where you live. Metro Atlanta saw on average 1 to 3 inches, with 4 inches or more reported in extreme north Georgia.

Before Tuesday's snow, Atlanta had gotten 4.2 inches of snow, nearly double its normal 2.4 inches.

The weather is expected to remain chilly but dry for the next few days in north Georgia, with warmer, dryer weather ahead for the weekend.
