PHOENIX — We're about five degrees above normal but, a cool down will kick in by mid-week and bring more seasonable temperatures.

A cut off low to our west and a storm system to our north with work together this week to bring a little bit of rain to Arizona.

Monday we'll remain cloudy and warm with westerly winds kicking in.

The chances are slim for rain (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 early Thanksgiving morning for NE AZ, although most of Thursday looks dry for now.
High elevation snow, above 7500 feet will be light and possible Tuesday night into Wednesday morning.

Cooler air coming in will drop highs into the low to mid 70s across the Valley just in time for Thanksgiving and keep temperatures in the 70s through the long holiday weekend.
