Today and Tuesday the inland areas of Northern California will be mostly clear with temperatures slightly above normal.  Winds will be light becoming south to southwest in the afternoon.  Wednesday the high pressure area that dominates our weather will weaken as a low pressure trough moves through Canada.  This will allow temperatures to cool a few degrees.  There will also be a chance of isolated afternoon and evening thunderstorms Wednesday over the areas north of Redding.  Light moderate southwest winds will occur Wednesday afternoon.

Thursday through at least the weekend high pressure will be over the western U.S. (see map below).  Skies will be clear and temperatures will warm to 3 to 6 degrees above normal by the weekend. Winds will continue relatively light.

This morning's satellite picture (below) shows a nice looking low pressure area off the coast.  However, the high pressure area over the western U.S. is stronger and that low will move northeastward over the next few days and then across Canada (see map below).    The next 7 to 10 days the inland areas of Northern California will be sunny with a few afternoon cumulus clouds over the mountains.  Temperatures will be 3 to 6 degrees above normal.  Winds will be light increasing from the south and southwest in the afternoon.

The picture below is from the morning of the 27th.  To get an updated image click on this   LINK .

I am again posting an animation of the water vapor satellite picture.  This is because the low pressure area is very weak and the water vapor shows it better.  To answer the question from the comments of the last blog.  This water vapor image is from the upper levels of the atmosphere and focuses on moisture at that level.  Approximately 30000 feet. This image is from this morning to get an updated image click the link above.

A weak upper level low pressure area is just off the coast and will move across Northern California today.  The low will trigger thunderstorms over the foothills and mountains with an isolated thunderstorm possible in the north end of the valley.  Temperatures today will be slightly above normal. 

Tuesday will be sunny with above normal temperatures and light winds.  Wednesday there will be some afternoon cumulus and isolated thunderstorms over the higher elevations north and east of the valley.  Temperatures Tuesday and Wednesday will be about 5 degrees above normal.  

The map below shows the weather pattern we will be under Thursday through the weekend.  Strong high pressure will be over the western U.S. with a low pressure area moving into Canada.  Inland areas will have clear skies with temperatures 3 to 5 degrees above normal.  Winds will light nights and mornings increasing in the afternoon from the south and southwest.

The low pressure trough that brought showers and thunderstorms to the area is moving slowly eastward.  This morning we will see partly cloudy to cloudy skies with a few showers over the higher elevations and chance of a sprinkle in the north end of the valley.  Clouds will be decreasing in the afternoon with any shower activity confined to the areas east of the valley.  Temperatures today will be quite a bit below normal.  light to moderate southwest to west winds are expected.  

Sunday looks partly sunny with temperatures warmer but still below normal. Winds will be light. Monday and early Tuesday a low pressure area will move across Western Canada and the Pacific Northwest (see map below).  This system will bring clouds to the north state and keep the temperatures a little below normal.

Tuesday afternoon high pressure begins rebuilding over the west coast and this high will dominate our weather through at least next weekend.  Skies will be clear.  Temperatures will be warming and will be above normal by Wednesday.  Gusty north winds will occur from late Tuesday through midday Thursday.

High pressure is over the western U.S.  Today should be sunny with temperatures a few degrees above normal and light winds.  A low pressure trough is developing in the Gulf of Alaska and will drop southeastward and move across Northern California on Friday (see map below).  Thursday temperatures will be cooler with increasing clouds and south winds in the afternoon.  Partly cloudy to cloudy skies and scattered showers and thunderstorms are expected Friday.  Saturday the trough will be moving eastward.  There could be a few showers early Saturday over the higher elevations east of the valley but overall skies will be clearing.  

Sunday through next week high pressure will be over our area.  Temperatures will back to near normal by Monday and remain normal to slightly above normal through the week.

High pressure is along and over the west coast and will.hold there through Thursday afternoon.  During this time skies will be mostly sunny.  Temperatures today will be a few degrees below normal with temperatures Tuesday through Thursday normal or a few degrees above.  Winds will be light.

Thursday afternoon a low pressure trough will be approaching the coast and will move across the north state on Friday (see map below). This system will bring scattered showers to our area Thursday night through Friday evening.  Most of the activity will be in the foothills and mountains but there should be a few light showers in the valley from Chico northward.

High pressure bounces back over the area on the weekend.  This will clear tnings out and bring temperatures back to near normal by Sunday and Monday.
