PHOENIX -- An area of low pressure is tracking across Arizona Friday through Sunday. This will keep temperatures cooler than normal and bring the chance for isolated showers and storms across parts of Arizona. The best chance for showers and storms over the next three days will be across the higher terrain. 

The Valley will see a 10 to 20 percent chance of an isolated shower or storm Friday afternoon through Sunday afternoon. Any storms that develop could produce erratic winds. Dust could also be a problem from outflow boundaries of thunderstorms in dust prone areas. 
 
Otherwise, in the Valley, look for partly sunny skies through Sunday with highs in the upper 80s Friday, low 90s Saturday and mid 90s Sunday. 
 
For crews battling the Slide Fire in the Sedona area, there's a slight chance of isolated storms Friday through this weekend. Winds Friday will be from the south at 5 to 10 mph with gusts of up to 20. If there's a thunderstorm that develops, winds will be stronger. The high will be 74 Friday afternoon.
