Wednesday will see a slight chance of showers after mid-morning, with highs near 58 degrees and calm winds. Wednesday night is expected to be partly cloudy with lows around 43.
The most significant rainfall is forecast Thursday night, with a 70 percent chance of showers after 10:00 p.m. Rainfall totals are projected between 0.5 and 1 inch, with higher amounts in foothill and mountain areas.

The weekend outlook is favorable, with mostly sunny skies Saturday and highs near 62. Sunday and Monday are expected to be sunny with highs near 66.
