Tomorrow should see more showers, primarily before noon, and there will be more widespread fog before 2 p.m. The high temperature should reach about 60 degrees. There is a chance of rain tomorrow night, with cloudy skies and a low temperature about 42 degrees.

On Wednesday and Thursday, the weather service predicts, skies will be cloudy with a chance of rain both days and high temperatures in the upper-40s.
