PHOENIX — It's been an incredibly warm November in the Valley!

Phoenix has hit 80 degrees or more 25 times this month. That's the most ever, breaking the old record of 24 days set in 1949.

With high pressure in control all week, the 80s will stick around heading into December.

Wednesday's record high is 83 degrees set in 1949 and we could tie that.

Thursday's record high is 84 degrees set in 2017. Right now, the forecast calls for a high of 82, so that record is likely safe.

But, we'll be within a degree of Friday's record high of 81 set in 1940.

Then, we'll drop into the upper 70s over the weekend.

Mornings will stay cool, at least. Expect overnight lows in the 50s all week long.
