Today will sunny across all of northern California with temperatures a little warmer and  light to moderate north to northeast winds.  Strongest winds will be in the Sacramento Valley this morning where gusts will reach 30 mph.  A low pressure trough is moving down the Canadian coast this morning and by Tuesday night a portion of this trough will be moving into the Pacific Northwest and northern California. (see map below)  This system will bring cooler temperatures with partly cloudy to cloudy skies late Tuesday through early Thursday.  There will be scattered showers and possible thunderstorms over the mountains with a chance of a shower in the far north end of the Sacramento Valley.  Temperatures will drop 4 to 8 degrees Tuesday and then another 10 to 15 degrees on Wednesday.  Max temperatures on Wednesday will be in the upper 70s in the Sacramento Valley with the mid 50s and 60s in the foothills and mountains.   The trough will be east of our area by Thursday afternoon and then we will go into a late summer or early fall type weather pattern, shown on the map below for Saturday.   The large scale high pressure ridges will be to the east and south of our area and the large scale low pressure troughs and jetstream will be to the north.   This pattern will hold from late Thursday through next weekend and will result in dry weather with temperatures a little below normal.

The low pressure trough is east of the area and high pressure is temporarily along the coast.  This will bring sunny skies to all of northern California today with temperatures a little cooler than yesterday.  Gusty north winds will occur in the Sacramento Valley and over the higher elevations.  Labor Day will be sunny and a little warmer with the north winds decreasing in the afternoon.  The big change in the weather starts Tuesday as the low pressure trough now in the Gulf of Alaska moves into western Canada and splits apart with a low pressure area forming on the southern end.  The map below shows this low over northern California on Wednesday.   Tuesday's temperatures will be 4 to 8 degrees cooler than Monday with some clouds beginning to move across northern California in the afternoon.  Wednesday will be partly cloudy to cloudy with showers over the mountains and a chance of a shower in the north end of the valley.  The combination of cool air from the trough and cloud cover will really cool temperatures Wednesday with the north valley expected to be in the 70s and the foothills and mountains in the mid 50s and 60s.  The trough will be east of the area by midday Thursday.   However, temperatures will be slow to recover as another low pressure trough will be approaching the coast by late Friday and the weekend.

The low pressure trough is now moving into western Canada.  This is a dry and fairly weak system but the southern end will move across northern California this afternoon.    This will drop temperatures 2 to 6 degrees with increased south to southwest winds this afternoon.  Sunday will be cooler especially in the mountains as the cold air behind the trough moves into northern California.  Gusty north winds will startup in the northern Sacramento Valley later tonight and continue through Monday.  Monday we will be between systems with sunny skies and temperatures a little warmer than Sunday's.  Tuesday the next trough moves into western Canada and this system will split apart with the southern end  forming an upper level low that will move across northern California late Tuesday and Wednesday. (see map below)  This system will bring partly cloudy to cloudy skies to northern California with scattered showers in the mountains and a chance of a light shower in the northern end of the Sacramento Valley.   Temperatures will continue to cool with high temperatures Wednesday upper 70s in the north valley and 50s and 60s in the foothills and mountains.   The trough will be east of our area by midday Thursday but temperatures will be slow to rebound and by the end of next week we still be 4 to 8 degrees below normal.  Another low pressure trough may drop southward along the coast next weekend.

The high pressure area that has been along the coast is beginning to weaken as a low pressure trough pushes into western Canada.  Temperatures today will be about like yesterdays in the foothills and mountains and 2 to 4 degrees cooler in the Sacramento Valley.  Temperatures will cool a little more on Saturday as the southern end of the trough brushes northern California. This is a "dry" system and will only bring scattered clouds to the far north end of the state...however...gusty southwest winds will also occur over the higher elevations on Saturday.  The cool air behind the trough will be over the area on Sunday and this will drop temperatures 5 to 10 degrees from their Saturday levels.   Another trough begins to drop southward along the coast Monday and by late Tuesday a weak upper level low will have formed on the south end of the trough (see map below).  This system will be strong enough to bring partly cloudy skies to the north state with a chance of showers in the northern mountains late Tuesday and Wednesday.  Max temperatures by Wednesday will be upper 50s and 60s in the mountains and 70s in the Sacramento Valley.

***********************************************************

Hurricane Earl poses a major threat to the east coast. Click here for the latest satellite images of the hurricane.   The National Hurricane Center has it  forecast to move up the east coast during then next 48 hours.  Below I have attached the latest forecast storm track.

**********************************************************

Light north winds continued all night in the north end of the Sacramento Valley and that made for a warm night with the Redding airport staying in the upper 60s while the thermal belt areas on the west side of town only dropped to the low to mid 70s.   High pressure is over California and today will be 3 to 5 degrees hotter than yesterday with the Redding and Red Bluff areas 100 to 104.  The valley areas to the south....(Chico, Biggs) will be in the upper 90s and the foothills and mountains will be upper 80s to mid 90s.   Temperatures will cool slightly Friday as the high pressure area begins to weaken as the low pressure trough shown on this mornings satellite picture moves into western Canada with the southern end brushing northern California.  Further cooling will occur on the weekend and by Sunday we can expect temperatures  12 to 15 degrees cooler than today's.  The trough should be east of our area by late Sunday.  It looks like a colder and stronger low pressure trough will drop southward along the west coast early next week.  This system will keep our temperatures below normal and could bring showers to the northern mountains.

Hurricane Earl poses a major threat to the east coast.  The National Hurricane Center has it  forecast to come very close to the east coast.  Below I have attached a forecast of the latest forecast storm track.

**********************************************************

 

High pressure is along the west coast and over the southwestern U.S.  This will bring sunny and warmer weather to northern California with gusty north winds in the Sacramento Valley.  Temperatures today will be 4 to 8 degrees warmer than yesterday which will put the north end of the valley near the 100 degree mark.  Thursday will be hottest day with temperatures up another 2 to 4 degrees.  Friday we start back into the same old cycle the Pacific high moves back to the west and the southwestern high moves east.   This will allow a low pressure trough to drop southward along the west coast.   Temperatures will start cooling Friday and will cool through the weekend.  The map below for Saturday shows the trough along the coast.   The southern end of this system will brush northern California with just a few clouds and no precipitation.  It will bring gusty southwest winds to the higher elevations to the north and east of Redding.  This trough will move east of the area late Sunday...however another low pressure trough will drop in behind it and this will continue below normal temperatures for most of next week.

High pressure is beginning to build over the area and this will bring warming and drying to all of inland northern California.  The map below for Thursday shows the high at its strongest and this will be the hottest day with temperature 4 to 8 degrees above normal....north valley 100 to 103 and foothills and mountains mid 80s and 90s.  The high will begin to weaken Friday as the low pressure trough in the Gulf of Alaska shifts eastward.  The map below for Saturday shows this system moving into the Pacific Northwest.   This will be a "dry" system for northern California but will drop the temperatures back below normal for the weekend.   Summary... sunny across inland northern California with warming through Thursday and then slow cooling through the weekend. 

*******************************************************************

There was a comment/question about the La Nina pattern and the upcoming winter.  If you are interested in the El Nino/La Nina checkout this link  http://ggweather.com/enso.htm     It was complied by Jan Null, certified consulting meteorologist at Golden Gate Weather.  There is not a really good correlation on La Nina's and the expected winter.  Looking at the map types associated with La Nina's I would feel we have a colder than normal winter with close to normal precipitation.
