An upper level trough is pushing additional cold air into Metro Atlanta over the next 24 hours, bringing the coldest temperatures so far this season.

As a result, morning lows will dip into the mid to upper 30s in Metro Atlanta Thursday morning, prompting the issuance of a Frost Advisory across the area.

A fall frost can damage house plants and crops, which is why it’s prudent to bring in the mums and other items you may have outside.
