The weak upper level low pressure area is now over Northern California and is moving slowly eastward.   This system will trigger isolated thunderstorms over the areas north and east of Redding today.   Thursday the high pressure area will be back over the western U.S.  However, the high will be weakened and pushed eastward as a low pressure area develops off the Canadian coast (see map below).  Temperatures today will a little cooler than yesterday with southwest to northwest winds in the afternoon.   

Friday through early next week we will see mostly clear skies with temperatures slowly dropping back to normal or a few degrees above.  Gusty south to southwest winds will occur in some areas during the afternoon. 

One thing to watch is the low off the Canadian Coast.  One model takes it eastward and weakens it the other model closes or cuts it off the drops it southward along the coast, with it off the Northern California coast by the mid part of next week..

The clouds over Northern California this morning are from a frontal system that is nearing the coast and is being dissipated by the high pressure ridge that is over the western U.S.  This front has held together a little more than expected and there could be a few light showers over the northwest corner of the state.  Temperatures today will be near normal south of Redding and several degrees below normal north of Redding.  Gusty southwest to northwest winds will occur this afternoon.

The high pressure ridge will bounce back Thursday and will hold over the western U.S. for the next week (see map below).  Temperatures will be 3 to 7 degrees above normal and winds will be light.

Quite a light show last night as the low pressure area neared the coast and triggered showers and thunderstorms.  The low is currently moving onshore at about the Oregon/Calilfornia border and will continue eastward during the day.  The low will continue to bring showers and thunderstorms today to the area north of a line from Clear Lake to Red Bluff to Tahoe.  Skies will clear tonight and Sunday as the low continues east and high pressure tries to rebuild over the west.  Cool today then warming to a few degrees below normal Sunday.  

Monday through Wednesday the north state will be sunny with slightly above normal temperatures and light winds.  Thursday through the weekend we will still be mostly sunny but temperatures will cool to normal or a few degrees below due to a weak low pressure area moving into Canada and the Pacific Northwest (see map below).

The low pressure area is still off the coast but is moving slowly eastward.  It now looks like the low will take a little further south track and will move across the Oregon/California border late Friday and early Saturday (see map below). Today will be mostly sunny and Thursday we will see a few clouds with a chance of isolated thunderstorms over the mountains.  Temperatures will be near normal today and a few degrees below normal Thursday.  Light to moderate south to southwest winds will occur in the afternoons. 

Friday and Saturday the clouds and chance of thunderstorms will increase especially from Redding northward.  Most of the activity will be over the higher elevations but there is a chance of a thunderstorm moving across the north end of the valley.  Temperatures will be 8 to 12 degree below normal.  Gusty southwest to northwest winds will occur in the afternoons. 

Sunday high pressure returns over the western U.S.   This will bring a return of sunny weather and normal or slightly above temperatures for most of next week.
