Question:  But when will it end?
Answer:  The middle of next week!

A few forecast models are now forcasting a deep troft in the west that will bring us cooler temperatures and a possibility of rain here in the desert staring late Tuesday and through Thanksgiving Day. Temperatures are forecasted in the high 60′s by mid week and precipitation possibilities for the valley floor as high as 60% on Wednesday.

Now alot can happen with forecast models more than a week out so we will have to monitor them.
