I know you are dissapointed by the weather - however, it works great for me since now I won't be working on Sunday and can go diving.
I was in the Detroit River on May 3rd and registered a temp of 41 degrees. Although I was in a drysuit there were lots of wetsuit divers and they all seemed to be comfortable.
A few additional points/thoughts/reminders:
1) Stay out of the wind, and try to stay in the sun between dives. Even if you have dried off the wind can still cause you to loose more heat (or slow down your rewarming process).
2) When you get in the water but before you submerge - submerge your face without your mask on (or completely flood it). This will give you a chance to climatize yourself to the water temp and if you do have to do a mask clearing while diving you may prevent some of the extremeness of the ice cream headache. Doing this will also help you slow your breathing rate down some.
Enjoy - the diving in the Great Lakes is awesome ... not as many pesky fish to get in the way of the cool wrecks
