Forecaster: Waters, S.
 
Synopsis:

Today: Sunny with mild breezes and near-normal temperatures.  Highs will range from 91-93 degrees across the northern zones to 95-97 degrees for greater Phoenix, Tonopah and Gila Bend.  Overnight lows will drop to the low 60s for Wickenburg over to Carefree and mid to upper 60s for greater Phoenix.

Tomorrow: Sunny again.  Mild breezes, cloudiness and dew points picking up in the afternoon.  Highs up about 2 degrees from today.

Monday:  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 a moisture surge from the remnants of Hurricane Lorena.  Were this setup to pan out, it would be favorable for a severe weather outbreak and a potential widespread and heavy rain event to unfold across the region next week.  That being said, there is still large model uncertainty to the exact track and timing of this system.  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.  The possibility of issuing a Message 2 (Flash Flood Watch) tomorrow, which would also include a County Storm Warning, is looking likely to be issued tomorrow.
