High pressure continues over the west. Today and Thursday Northern California will be sunny with daytime temperatures 10 to 15 degrees above normal. Gusty northeast winds continue in some areas but will end early Thursday.
Friday a low pressure area will drop southward over the Pacific Northwest. The low will continue southward and will be over Oregon by Monday (see map below). The track of the low will still be the issue. At this time it looks like it will remain close to the coast over over land. This will limit the moisture available to generate precipitation. There could be isolated showers over the higher elevations north of Redding on Friday with partly to mostly clear skies elsewhere. Saturday through Monday the north state will be partly cloudy to partly sunny with a few showers over the higher elevations with the chance of a light shower in the valley. Temperatures will start cooling Friday and will be 10 to 20 degrees below normal by the weekend. Gusty southwest to northwest winds will occur at times Friday through the weekend.
Tuesday and Wednesday the low will be moving east. We will have clear skies with temperatures returning to normal.
