12.6 is a fine voltage for a car battery at rest and 14v indicates it is charging properly.
You can see how it drops all the way to 10 volts when cranking because the starter needs SO much more power than anything else and the colder the ambient temp is the more power it needs to turn the engine over properly.
Check it again tomorrow after it sits overnight or after it's been sitting for a few days again and for sure next time it won't start, that will give you a better idea of what is going on.
I agree with Brian you should probably check the terminals and cables for corrosion.
Like I said when my battery was going dead it would charge up to 12.6 or 12.7 after I'd driven it for a while and then stay relatively high and by the morning it would be down to 12.4 or 12.3 and had trouble cranking.. Put a new battery in and have not had any problems since.
I'm still eyeing up the battery as the cause of this it's the most likely culprit so we need to rule it out before looking at other systems. Don't replace it though until we can confirm this is where the problem lies, they aren't cheap.

They will definitely be lower tomorrow... It's a matter of how much lower. Check it before you start the car, you don't want to get any charge into it.
Just to give you an idea of charge levels on a 12v automotive battery (with no draw):
100% - 12.6+ V
75% - 12.4 V
50% - 12.2 V
25% - 12.0 V
Dead - 11.9 and below
It should be able to stay between 100 and 75% charge overnight and even for a few days unless something is wrong (device is drawing power when the car is off or battery is bad)
My original battery went last winter in my 2010 so it won't highly surprise me if it's toast.
Like I said the useful life is generally meant to be 4-6 years... If you look most places won't warranty even the fanciest most expensive batteries much past 4 years.
Another thing to note is a charged battery won't generally freeze, however if it discharges enough it can freeze and once it's done so once it can significantly degrade the quality of the battery.

Thoughts?

Who is they?
I can't imagine how sitting for a couple days would somehow make the gas low or where water would come from..
If your fuel pump was going bad you would be having random problem starting regardless of sitting or not and it would also stall out on you while driving.
Also the way you said it started sounds like you had un-burned gas in the cylinders.
Another thing to try next time is hold down the gas pedal while turning it over a few times and then try and start it....

But for now we'll just see if it happens again. Thanks for all the help. I learned a lot!
Out if curiosity, I just checked my old winter beater, and it was 12.3v but had a lot of green corrosion on the positive post. I'm going to clean it with some baking soda and a toothbrush

Did you have the dealer actually check it while it was still under warranty? If they did but didn't fix it they should still be able to fix it under warranty (if it isn't actually the battery)
I've ran my tank down to like fumes in the freezing cold and I've never had a problem starting mine. I wouldn't expect that to be a problem, and if it was due to low fuel somehow it wouldn't just "fix" itself.
It wouldn't be a bad idea to clean off the corrosion it can cause problems starting at some point and you don't want to have more problems....

Mine eats a battery every two years. The factory battery lasted almost three, but I kept topping it off with distilled water. I have a nice little Black n Decker charger I got online for $12 and plug it in whenever out of town, to help.
I was fussing with a friends Audi for different starting problems for six months until he mentioned that the battery was six friggin years old. Replaced it and no problems again. Newer cars are just way more sensitive to voltage/amperage changes.
I get a decent replacement with the longest warranty and highest CCA from a national chain so when it dies, they credit you part of the $ back.
