The Valley has seen above-normal temperatures this November — in the mid- to high 80s and low 90s, and now heading into the weekend, with a storm on its way, they're expected to drop.
Meteorologist Alicia Ryan is with the National Weather Service in Phoenix.
"By Saturday afternoon into the evening and the overnight period into Sunday, better chances for the Phoenix metro to [see] some rainfall potential as well," Ryan said.
She said a low pressure system is also coming in, which is expected to drop highs in the Phoenix area to just under 70 degrees.
