How does late April until May 4th look for southern Utah?

Will there be any wildflowers in bloom? How is the weather if we fly into Vegas and just tour the southern parks of Utah? We travel a lot, but this is one place my hubby is really wanting to go.
Thanks so much,
Nan

Using the Grand Staircase-Escalante National Monument, which covers a large portion of southern Utah, as a proxy for everything else, it looks like March is as good a guess as any. But of course, that will vary with the year, rainfall, elevation, etc. and no one can accurately predict desert wildflower blooms.
