The owners manual lists the following viscosities for synthetic oil, "mostly higher than 50F":
10W40
15W40
15W50
For "mostly lower than 14F" they list:
10W40
10W30
5W30
So how would 0W40 be ok? I guess because it is warm now the oil will be thick enough?

lots and lots of oil threads, so a search may help (or be completely overwhelming) and you're right. quick way to start a flame war.
anyway, the 0w oil is more of a compromise that i think makes it fairly reasonable to expect that if the car is in really cold climates it'll be fine and in warmer climates it'll be okay until it's warm. remember, the lower the number the less viscous the oil. so it'll flow easier at colder temps.
personally, i use 10w40 (castrol syntec) as i think a lot of people on the forum do as well. some stick with the porsche factory mobil 1 0w40.
just don't do anything-30...
