Wednesday weather forecast: Warm!

Posted: Updated:

PHOENIX -- It will be an unseasonably warm Wednesday, with Valley highs topping out in the low 80s.  High pressure will bring those warm temperatures under mostly clear skies today and tonight before a change arrives for Thanksgiving. 

A storm system will move our way tomorrow, bringing a mostly cloudy holiday across the state.  Temperatures will be a bit cooler with Valley highs in the low 70s, and topping out in the 50s and 60s in the high country. 

There is a 20 percent chance of showers in the Valley Thursday evening into Friday morning, along with a slight chance of thunderstorms. 

Snow could fall in the high country, although more is likely in Eastern Arizona, in the White Mountains. 

The storm clears out quickly on Friday for a sunny and warmer Black Friday and weekend ahead.
