Forecaster: Waters, S.
 
Synopsis:

Today: Sunny with mild breezes and near-normal temperatures.  Highs will range from 93-95 degrees across the northern zones to 97-99 degrees for greater Phoenix, Tonopah and Gila Bend.

Tomorrow: Not enough change from today to be worth detailing.

Sunday:  Start the day with mostly sunny skies and temperatures bump up just a bit.  Look for middle 90s across the northern county zones and right around 100 for greater Phoenix, western and southwestern zones.  Dense cloud-cover begins to move in for the evening hours.

Extended Forecast: We’re keeping close tabs on the late Sun-Tues night time frame.  Model guidance continues to show a rigorous Pacific trough dig south into the SoCal/Nevada region and interact with moisture from the remnants of Hurricane Lorena.  This trough could drop down over Rocky Point, become a cutoff low, then slowly meander back into central AZ by Thursday.  Were this setup to pan out, it would be favorable for a severe weather outbreak and a potential widespread and long-term heavy rain event to unfold across the region next week.  At this point models have shifted the areas of heaviest impact from central AZ to the west about 50 miles.  That being said, there is still large model uncertainty to the exact track and timing of these systems.  We’ll have more details to share as more information becomes available, but it’s not too early to be considering response and staffing needs for next week.
