Cover art for Colder Weather lyrics by Zac Brown Band

This is what I've heard...

Zac Brown's brother is addicted to Meth, which is known as "ice," hence the reference to colder weather. Recently, his long time girlfriend left him because she couldn't compete with his addiction any longer.

She wants him to choose her over his addiction - "She'd trade Colorado if he'd take her with him"

However, he once again chooses the drug over her - "She's answered by the taillights shinning through the window pane."

Of course he wants to get over his addiction and be with her but can't that easily - "I want to see you again, but I'm stuck in colder weather. Maybe tomorrow will be better, can I call you then?"

It ends with him not being able to shake his addiction, but being hopeful that "they'll soon be together."

Excellent song that depicts the struggles of addiction.

it didnt even occur to me that this was about drugs... Good explaination, it completely changed the song.

Not Valid

@truss007 This answer is actually the correct answer.

I have heard this through multiple sources, and also that the brother passed away from his addiction to ICE after he graduated from the University of West Georgia.

@truss007

After Zac graduated from University of West Georgia, to make that clear. It was then his brother (purportedly) died of a meth (ice) overdose.
