Forecaster: Henz, D.


After talking about nothing other than warming temperatures over the last week, a pivot in the upper-level pattern will bring welcomed changes to the forecast this week. Looking at the big picture, a large upper level trough will set up across the western US helping to suppress the Pacific ridge west of the Desert Southwest. Several dry disturbances are set to pass through the Great basin ultimately bringing periods of high clouds, breezy to windy conditions, and more importantly cooler temperatures to AZ.

For today plan on periods of overcast skies due to passing high clouds. Afternoon temperatures will step back into the 91˚F-93˚F range around the Valley with higher terrain areas reaching the mid 80s. West/southwest winds will be breezy in the 7-15mph range with gusts around 20-25mph this afternoon/evening. Overnight low temperatures will dip into the mid 60s around the Valley under partly cloudy skies.

Plan on even cooler temperatures and windier conditions tomorrow as a weak disturbance passes to the north of the region. Daytime highs will fall further into the 87˚F-89˚F range around the Valley. Windy conditions are expected for most of the day in the 10-20mph range with gusts as high as 30-35mph. Localized areas of blowing dust and hazier conditions are likely across portions of the lower deserts. Breezy conditions will persist through mid-week along with a modest rebound in daily temperatures. Expecting sunnier skies on Wednesday with highs in the low 90s around the Valley followed by similar temperatures on Thursday despite another uptick in high clouds.
