An isolated shower or thunderstorm is possible early Tuesday morning before the sun reappears later in the day. Rain brings the start of cooler, fall-like temperatures, with highs between 71 and 75 degrees.
Later in the week, temps continue to drop, lingering in the 50s and 60s, according to Avalos.
