For tonight, look for increasingly cloudy skies with a chance of scattered showers developing. Overnight lows will be mainly in the low to mid50s. Tomorrow under mostly cloudy conditions and a chance of continued showers, well see highs ranging from about 60 at the coast to low 70s inland. Heres the accuweather sevenday forecast.
