The high pressure ridge is weakening and moving eastward as frontal systems approach the coast. The first system will move through tonight and Thursday. This front will bring light rain or showers to the foothills and mountains with a chance of a light shower in the valley. Late Thursday and Friday we will see partly sunny to partly cloudy skies with below normal temperatures. Then late Friday and Saturday the next system moves through. This will also be a weak system with the precipitation mostly over the higher elevations with a light shower possible in the valley.
Sunday high pressure begins to build along and over the west coast. A strong high pressure ridge will be over the west coast next week (see map below). The north state will have clear skies with temperatures 8 to 12 degrees above normal the last half of next week. Gusty north winds will occur Sunday and early Monday with light winds the rest of the week.
