'01 Galant ES won't start -- freezing temp's

My 2001 Galant ES sat outside for about a day and a half and we've had below freezing temperatures (teens and twenties). Car wouldn't start this afternoon --- interior lights worked, fan blew weakly, but got little response from trying to start the engine .. just some of that sad clicking sound. Owner's manual isn't too helpful. Is there a quick(-ish) fix or do I just have to wait until the temperature rises to above freezing and get it jumped? Thanks.

Jump it! the battery is jus getting discharged from the cold. You could bring your battery into your house overnight and that will keep it charged
