Forecaster: Field, B. and Henz, D.
 
Synopsis:

Expect cooler temperatures and breezy conditions as general troughing affects AZ today and tomorrow. Currently there's no rain in the forecast as this is a dry system, but temperatures are expected to dip well below normal this weekend providing a much deserved relief from the summer heat. The next weather pattern is right around the corner so be sure to read the full forecast for more details on storm chances for early next week.

For today, expect breezy conditions and clear skies and with mostly south westerly winds 15-25 mph.  Afternoon highs are right where they should be in the 99°F - 101°F range. Overnight expect decreasing winds leading to calm conditions and lows in the upper 60’s to low 70’s across the Valley. For tomorrow expect similar conditions but a bit cooler with highs near 95°F - 98°F range for the Valley. Westerly flow persists near 10 mph. During overnight hours expect lows in the upper 60s’s with a few locales in the low 70’s. For Saturday expect calm and sunny conditions with afternoon highs in the mid 90’s. 

Extended Forecast: We’re keeping close tabs on the late Sun-Tues time frame. Model guidance continues to show a rigorous Pacific trough dig south into the SoCal region and interact with moisture from the remnants of Hurricane Lorena. Should this setup pan out, it would be favorable for a severe weather outbreak and a potential widespread heavy rain event to unfold across the region early next week. That being said, there is still large model uncertainty to the exact track and timing of these systems. Any negative changes to the track would result in significantly less impacts for our area. We’ll have more details to share as more information becomes available.
