TUCSON - An old friend returns to the forecast to wrap the work week.
Dry Pacific air continues its ambush on Arizona, according to 4WARN Meteorologist Jeff Beamish. Sunshine prevails today as highs reach the 100s in Tucson. Today likely marks the 51st triple digit day of 2017 in Tucson, which is a typical amount of 100°+ days through mid August.
Monsoon moisture slowly start to return by Saturday, leading to scattered storms along the International Border & New Mexico border. While a stray storm can't be ruled out in Tucson by Sunday, scattered storms still appear to arrive Monday & Tuesday. Each day features a 30% chance of metro thunder.
Numerous computer models agree that Monday's storms will be confined to the afternoon & early evening hours. Much of Southern Arizona should see mostly sunny skies for Monday morning's partial solar eclipse. Temperatures during the late morning hours should be in the low to mid 80s for Metro Tucson.
