This morning's satellite picture (below) shows a low pressure area and frontal system moving toward Canada and the Pacific Northwest.  The southern end of this system will move across Northern California tonight and Thursday.  We will see a few clouds from this system with light showers over the northwest corner of the state.  Temperatures today and Thursday will be near normal.  Gusty southwest to west winds will occur in the afternoons.  

Friday high pressure begins to rebuild over the west.  This will result in a very strong high pressure area over the west Saturday through the mid part of next week (see map below).  Temperatures Saturday through early next week will be 10 to 15 degrees above normal.  Strong and gusty northeast to east wind will occur Saturday through midday Tuesday.
