PHOENIX -- High pressure centered to the west of Arizona continues to bring much warmer temperatures than normal.

It looks like temps will peak on Saturday around the Valley, with highs approaching 90 degrees. Overnight lows will be in the 50s and 60s for the most part.

Early next week, the ridge of high pressure shifts to the west as the whole jet stream pattern gets rather stacked up. That’s going to result in little day-to-day changes next week and no rain or snow.

It’s the same weather pattern that’s going to lead to some really cold weather in the eastern half of the country by late next week. You’ll be hearing the term “polar vortex” a lot.

As it is, we will see some gradual cooling next week. Monday we’ll see highs in the mid-80s. By the end of next week, highs will most likely be in the 70s.
