PHOENIX -- A weak weather system is bringing some slightly cooler air into Arizona, but not much in the way of any rain or snow. As a result, expect weekend highs in the Valley to be in the upper-70s, warming into the 80s next week.
The discussion from the National Weather Service says:
Visual satellite imagery shows continued clearing with just some remnant cirrus across northern third of Arizona and far southeast corner of the state. Other areas of southern Arizona and southeast California are clear as the upper level moisture source that produced the cloudiness over the past few days has mostly dried up.
Water vapor imagery shows the narrow dry slot along northern Baja Calif. across southwest Ariz. stretching over the Phoenix area. Temperatures across the area are several degrees below what they were 24 hours ago.
Phoenix's morning low was 60, which is 5 degrees below yesterdays low.
Trough extension from Canada and northern Rockies continue to reflect across Arizona and is passing over the state today, putting us under northwest flow aloft bringing cooler temps and drier air.
Little else expected for the next five days other than a gradual warming Sunday through Wednesday. The next item of interest is a possible Pacific storm at the edge of our extended period seven to 10 days out.
