I forgot to put antifreeze in my car last night and it got down to 20 degrees. It overheated on my way to work this morning. The water looks fine (no oil in it) and I have had no problems until this morning. Is it possible that the lines are just frozen and the water could not make it through.

You aren't going to know until you get it completely thawed out and run it. You could pressure test the cooling system then to see if you have any leaks. Very bad thing to let happen.

If not windy and you drove it the afternoon before it wasn't frozen until you drove it - it plugged up radiator, no flow and overheat.
That's just the beginning. It's had no antifreeze in it for protection against corrosion along the way then an overheat on top. Begin checking more for what overheating did and if it now leaks like nuts (radiator or tanks to it) you can't pressure test it so the disaster grows,

I have to wait until I get off work to really look at it more but, when it was overheating the only leaking was from the overflow on the coolant reservoir.

This suggests you have this at work now? At best it's low on even water alone if above freezing so don't drive it at all now. If you can't add antifreeze to radiator itself if not cap on radiator it's not going to suck any back in from reservoir tank if any leak in system and that's not how you fill a system without a radiator cap on radiator anyway.
Your call. You stand a chance of little to no damage now. It won't get better by driving it more but would have to run it to properly fill it up unless you can vacuum fill it where it is then find out about other leaks when run.
It's already trouble so do as you wish AYOR but note that when heater stops throwing heat when it's warm at all (engine) then it's either still too low on coolant or boiling again from lack of coolant anything. Boiling liquids do not transfer heat, warm/hot liquids do.
It's still on the list but why or what happened or leaked that you only added water to begin with? That problem probably still exists too,

If it's still ayt work, that means it's still sitting outside in the cold with no anti freeze. If you didn't have engine damage this morning, you probably do by now.

Thank you all for the advise. I ended up getting it towed and got a proper coolant flush done. Everything is fine now. I have no leaks and no engine damage!

You are VERY lucky if that proves true. Hope so. Don't let that happen again or even close,
