Las Vegas is an example of the 10 degrees warmer this week than normal. Their average right now should be 98 Degrees

 But, instead it is:

103 Sunday

104 Monday

108 Tuesday

108 Wednesday

107 Thursday

104 Friday

108 Saturday

Las Vegas and Palm Springs often have similar temperatures depending upon other factors like wind and rain and lightning and other weather factors. But, very often their temperatures are very close so this makes their weather generally very similar year around.
