High country storms, cooler than normal temps this weekendPosted: Updated:
PHOENIX -- An area of low pressure continues to slowly track east across Arizona this weekend. The system will fire up isolated to scattered thunderstorms across the high country Saturday afternoon through Sunday evening. A stray storm drifting into the Valley during this time cannot be ruled out.
Any storms that develop could produce wind gusts of 30 to 40 mph, blowing dust in dust-prone areas and lightning. Otherwise, look for partly sunny to mostly sunny skies.
For crews battling the Slide Fire in the Oak Creek Canyon area of Sedona, humidity is higher and temperatures will be in the mid-70s. There’s a chance of scattered storms. Winds will be out of the west at 10 to 15 mph with gusts of 20. If storms materialize in the area, winds could produce erratic fire behavior and any heavy downpour could produce debris slides.
This area of low pressure is also keeping temperatures a few degrees cooler than normal across the state. The Phoenix-metro will see highs in the low 90s Saturday with highs in the mid-90s Sunday.
By Monday, high pressure starts to build into the region. This will kick off a drying and warming trend. The Valley will see triple-digits starting Memorial Day and continuing through the week.
