Forecaster:  Waters, S.

High pressure to our southeast and low pressure to our west are creating an atmospheric sandwich, driving moisture our way from the south. Surface dew points are in the middle 50s to low 60s – up about 10 degrees from this time yesterday. There are chances later in the day for light showers, mostly in the western and southwestern portions of the County. This moisture intrusion will lower afternoon highs to the middle 90s for the northern zones and low 100s for greater Phoenix and Gila Bend. Skies will be partly to mostly cloudy with light breezes except near storms. Overnight we’ll remain partly cloudy with a slight chance for showers, with middle 70s north to 80 for central Phoenix. Tomorrow a chance of rain remains in the afternoon/evening with more county-wide coverage and even lower afternoon highs from the low to upper 90s. Sunday will be mostly sunny with highs much like today – middle 90s to right around 100 degrees.
