PHOENIX — Dry weekend even with all those clouds. Temperatures remain about five degrees above normal for a few more days before a cool down kicks in.

Sunday gusty winds across Northern Arizona are expected. A Wind Advisory has been issued for the Upper Colorado River Valley starting tonight at 11 p.m. through Sunday at 7 p.m. Gust in this area could be as storn as 50 mph.

By Monday, winds will pick up and it will get breezy here in the Valley and across southeastern Arizona.

Then, a storm system will move in from the west on Tuesday and Wednesday. This time, we could even see some rain and snow in parts of Arizona!

The chances are slim (at 10 to 20 percent for the Valley and 20 to 30 Percent for N, NE AZ), but they will kick in on Tuesday, ramp up a bit on Wednesday and could even linger into Thanksgiving morning.

Cooler air coming in will drop highs into the low to mid 70s across the Valley just in time for the holiday, too.
