Tomorrow Sunday) : Showers are still possible almost at any time. Chances for more consistent rain increase as a morning warm front approaches. Temperatures behind the front are expected to reach the upper 60s to low 70s late in the day as we see some flashes of sunshine. The more sunshine, the higher the chance of afternoon thunderstorms.
