.Forecast Summary...An area of low pressure is located off the California coast this morning and will move inland tonight. Gusty southerly winds will be observed today in advance of it. The low will pass over our area this weekend. Showers and isolated thunderstorms mainly for the higher terrain will begin Saturday afternoon and last through Sunday. There could even be a few snow showers for the highest elevations. Little to no accumulations are expected. It will also be cool and breezy. The low will head east early next week as high pressure builds over the region. This will result in a warming trend under mostly sunny skies.
