Tuesday and most of Wednesday the north state will be partly to mostly sunny as high pressure tries to rebuild along the coast.   Late Wednesday and Thursday a low pressure trough and frontal system will move into the Pacific Northwest  with the southern end brushing Northern California.  Wednesday night and Thursday we will have partly cloudy to cloudy skies with a few showers mainly over the higher elevations.  

Friday through the weekend high pressure rebuilds along the coast.   Northern California will be sunny with above normal temperatures and gusty north winds.

The jetstream is still just to our north.  Today through midday Thursday Northern California will be partly cloudy to cloudy with a few showers over the coastal and northern mountains.  

Thursday afternoon through the mid part of next week the high pressure ridge along the coast will push a little farther north (see map below).  During this time the north state will be partly sunny to partly cloudy with normal or slightly above normal temperatures.  

At this time it looks like a return to a wet pattern late next week.

Want to see how this year compares with other years.  This table was done by Jan Null at Golden Gate Weather Services.  http://ggweather.posthaven.com/ranked 

 If you look at the satellite picture and two maps below you see that the weather pattern will change very little over the next week.  A low pressure area will remain off the Canadian Coast with the jetstream splitting as it moves across the Pacific.  The jetstream will be just to our north but will shift a little north and south during the week.  This type of weather pattern isn't extremely wet for Northern California but will keep things cloudy especially over the coastal and northern mountains. 

Today and Tuesday most of the north state will have periods of rain or showers.  Precipitation amounts will be light in the valley and lower elevations   Snow levels will be 1000 to 1500 feet north and 2000 to 2500 feet south.  

Wednesday and Thursday the showers will be confined to the areas from Redding northward, with partly cloudy skies elsewhere.  Snow levels will rise to around 4000 feet.

Friday through the weekend it looks like the jetstream will sink back a little to the south and this will bring a chance of light showers or rain to all of the north state.   Snow levels will be 5500 to 6500 feet.

Want to see how this year compares with other years.  This table was done by Jan Null at Golden Gate Weather Services.  http://ggweather.posthaven.com/ranked 

A low pressure trough is developing off the coast. (see satellite picture below).  This trough will continue slowly moving southward and then will move eastward across Northern California Sunday afternoon.  Rain will spread over the area today and continue through early Sunday.  The precipitation will turn to showers Sunday afternoon and end by evening.  Snow levels are 4000 feet north and higher south...but will be dropping.  Snow tonight and Sunday will be 1500 to 2500 feet north and 2500 to 3500 feet in the south.  

There will be brief break late Sunday and then a weaker storm system will move across the area Monday and Tuesday.  Light rain or showers is expected Monday and Tuesday with snow levels 2500 feet north and 3500 feet south.   

Wednesday and Thursday we will be under a weather pattern like the one shown on the map below.   A weak high pressure ridge will be over the western U.S. with the jetstream just to our north.  The areas north of Redding will be partly cloudy with a few showers over the higher elevations and the areas south of Redding will be partly sunny to partly cloudy.  

It looks like another weak storm system will bring light precipitation to the area next weekend.
