Desert air is moving in aloft from the west. Temperatures tonight with light wind and fairly low humidity will still be comfortable. Very warm desert air aloft will mix down each afternoon with the stirring of the air with daytime heating. 100F heat is likely. A bit more of a gulf influence will move in during the weekend with fair weather clouds, higher humidity, and temperatures under 100F.
I'm expecting clear with comfortable temperatures late tonight, low in the high 60's. Sunny and hot Wednesday through Friday, highs around or a bit above 100. Partly cloudy Saturday through Monday, highs in the high 90's. Mostly sunny Tuesday, highs around 100.
