PHOENIX (AP) — Overnight temperatures in metropolitan Phoenix haven't dipped below 90 degrees for the past three days.
Monday's overnight low in Phoenix was 91, and Sunday's was 92. The record high for an overnight low is 96.
Sunday was the first night of the year when the overnight low temperature remained above 90.
Overnight low temperatures tend to stay high once the dew point increases and the monsoon has begun.
But apart from morning showers that set up a relatively cloudy day on the Fourth of July, the cooling rains have been absent so far this summer.
The heat could let up a little bit in coming days.
Monsoon storms are possible, although the chances of a storm are no greater than 30 percent.
