What Kind of Tree is This?

This pretty tree is growing in the circle median that sits in the middle of our neighborhood. I have been trying to identify what type it is, but so many of the white flowering trees look alike to me! I saw the first blooms on this tree a week or so ago. We live on the Texas Gulf Coast where all sorts of pretty things are finally starting to bloom!

Is it a cherry tree of some type?

Or maybe a tea crabapple?

Or, is it something else completely?

If you know what type of tree this is, please let me know. Thanks!
