Las Vegas 21st March 04th April

[Arrows]

I'm flying out to Vegas early Saturday morning and will be in Vegas until Wednesday where i will fly to California. Any advice on progged temps for the period listed above as ive seen different temperature variations. It fluctuates from 71-85F etc, with clear blue skies. I know that it's not going to be mega hot but I'm sure even mid 70's will seem warm compared to what we've had here. So please,,,any predictions would be massively appreciated.
