Forecaster:  Henz, D.
 
Synopsis:
Morning analysis reveals a weak shortwave moving east into AZ. Weak lift ahead of this wave has allowed for some scattered high clouds and a gorgeous sunrise, though we’ll see little else from this system. There’s little change to the forecast through Friday with quiet weather conditions and continuing above average temperatures. It is worth noting that after today, daily temperatures will begin a steady downward trend through the extended period. Our attention now shifts to the upcoming weekend as model guidance is coming into better agreement on a pretty significant pattern shift that should play out into next week. As of now, a big cool down is all but certain, but there is still plenty of ambiguity in regards to possible precipitation chances during the Sunday-Tuesday time frame. We’ll shed some more light on the situation in tomorrow’s extended Outlook. 

For today plan on mostly sunny skies mixed with lingering high clouds and haze (smoke). Afternoon temperatures will warm into the 94˚F-97˚F range around the Valley with low 90s across the higher terrain locales. Variable winds will remain in the 3-10mph range with no gusts of any consequence to contend with. Overnight lows will remain crisp dipping into the mid to low 60s around the urban corridor.

Dry conditions and quiet weather will continue tomorrow across the state. Daytime highs will reach into the 93˚F-95˚F range around the Valley. Variable winds will continue to hover in the light category with no noteworthy gusts. Heading into Friday, we’ll likely see a steady uptick in passing high clouds as the day wears on. Afternoon highs are forecast to step back into the low 90s across the lower deserts.
