PHOENIX -- A strong ridge of high pressure sitting over the Southwest will bring abundant sunshine and record heat Friday. 

In the Valley look for highs topping out around 111 degrees, with temperatures up to 114 possible in the deserts further west. 

Most of the deserts of the state, including the Valley metro area, are under an Excessive Heat Warning today.  For the Valley, the warning is 10 a.m.-8 p.m. 

Lows tonight will be a bit warmer, but still cool to the 70s. 

Over the weekend, we cool off a couple of degrees, with 106 forecast for Saturday and 103 Sunday.

Next week looks a bit cooler as well, with more sunshine and highs near 100.
