The cutoff low pressure area is now over Northern and Central California and is moving southeastward. Scattered showers and thunderstorms will occur again this afternoon and evening over the foothills and mountains with isolated activity possible in the valley. Temperatures will be cooler today. Sunday most of the state will be sunny except over the Sierras south of Mt. Lassen, where isolated afternoon thunderstorms will occur.
Monday and Tuesday look clear with temperatures back above normal. Winds will be light.
Quite a change in the weather starting Wednesday. A strong...for this time of year...low pressure area will be nearing the coast late Tuesday (see map below). This system will move slowly across the north state Wednesday and Thursday. The low will trigger showers and thunderstorms. Temperatures will be below normal. Snow levels will be 5000 to 6000 feet. Periods of gusty southwest to northwest winds will occur. Friday looks partly cloudy over the areas north and east of the valley with a few showers. Temperatures will continue below normal.
Late Saturday and Sunday a weak system could bring showers over the areas from Redding northward.
