SATURDAY: Energy from the west will enhance rain chances yet again on Saturday (60%). A messy upper level setup will make it tough to pinpoint timing and amounts. Clouds and rain will make for slightly cooler temperatures.
SUNDAY: Quieter weather is forecast for Sunday, with the sun making a return. Highs will reach the mid-80s
MONDAY: Only isolated storms are expected (20%). Temperatures will reach to near 90.
