Hello, my name is ***** ***** I will be the immigration attorney helping you today.
Unfortunately, the only sure way to be able to come back in to the US is to submit an I-90 form to replace your green card online, print out the receipt notice, make an infopass and take the receipt before you leave and have your passport stamped with the I-551 emergency travel document. At this point you would not have enough time to do the infopass part. You can try to go to your local USCIS office tmrw if you have time and try to see if someone will see you on emergency basis with copy of your ticket. There's no guarantee.
If not, You can do the I-90 tonight and just print the receipt and take it on your trip to use to come back. You would then be taking a risk to depart from the US and try to get back in with the I-90 receipt together with the copy of your green card. It will be up to the CBP officers to allow you back in at that point or not.
Here is the I-90 form to do it and pay online https://egov.uscis.gov/e-request/Intro.do;jsessionid=abcFg1g7hmPEQ7viTM8eu
