As for the temperature, Friday's high of 66 degrees will drop to a chilly 58 in San Francisco on Saturday. The low is currently forecasted at 47. Other nearby cities could experience lows in the mid-30s, however.

" Cold front on track to bring widespread rain, cooler temperatures, and gusty winds this weekend," the National Weather Service said. "Behind the cold front Saturday afternoon and evening, there is a slight chance for isolated thunderstorms across the area.

"Scattered showers will persist into Saturday evening, but conditions appear favorable for a few locally strong updrafts that would support a rumble of thunder or two, as well as small hail."

The good news is that the skies will clear again on Sunday. Forecasters said that a warm up is on tap for the rest of next week with highs of nearly 80 degrees predicted for San Francisco on Wednesday.
