Phoenix weather: Warm-up begins

Posted: Updated:

PHOENIX -- A ridge of high pressure building over the Southwest means a warm-up is underway for Arizona. 

A new storm brings rain, snow and strong winds to the Northwest today, but the jet stream will stay well to our north, keeping skies clear and temperatures warm in Arizona. 

The average high for the Valley this time of year is 79 degrees, and we'll be near 80 today. Tomorrow, we'll jump another four to five degrees and we could see our first 90 degree day of the year on Saturday.  March 31 is actually the exact average day we see our first 90.  It hasn't been that warm in the Valley since Oct. 31. 

The heat won't last past Saturday, as temperatures are forecast to drop back about 10 degrees on Sunday with breezy conditions as well. 

No rain or snow is in the forecast for at least the next seven days, and both Snowbowl and Sunrise ski areas are set to close for the season on April 1.
