Arizona weather forecast: Sunny skies and above-average temps in Phoenix

4 p.m. Weather Forecast - 12/5/24

PHOENIX - The warmer than average temperatures continue across the state.

Like the last few days, cold air is locked over the eastern half of the United States and warm air is locked over the western half. As a result, temperatures continue to run toasty for December. Fortunately, a compact area of low pressure has passed over Arizona, which is keeping temperatures below 80 degrees in the Valley.

The area of low pressure is also producing a few light showers along the east and southeast parts of the state. A few clouds or a sprinkle may approach the mountains just outside the Valley. However, it is unlikely any showers will actually make their way into Phoenix due to the dry air in place atop the Valley.

The forecast high continues to warm into the upper 70s from Thursday through Saturday. Phoenix saw 78 Thursday, and is expected to hit 79 Friday and 77 degrees Saturday.

By Sunday into early next week, a new storm system will develop along the Pacific Northwest and move inland across the Mountain West. As it moves inland, cooler air will drop across the western United States. Sunday is forecast to hit 74 and Monday 73 degrees.

By next Tuesday and Wednesday, highs may drop into the upper 60s, which is average for December. The pattern remains relatively dry for the next week with a sunny to mostly sunny outlook day to day.
