High pressure back along the coast.  Today through Monday we will continue sunny with temperatures 15 to 20 degrees above normal.  Winds will be light.

Ref. the questions in last blogs comments.   The medium and longer range models show the ridge breaking down the last week of Nov.  Still looking to see a wetter Dec through Feb.

High pressure is over the coast.   We will continue to see mid and high cloudiness through Friday as low pressure troughs and frontal systems move over the ridge and into the Pacific Northwest.  Temperatures will continue above normal and winds will be mostly light.

Saturday through Monday the high pressure ridge rebuilds just off the coast. The north state will be mostly sunny with above normal temperatures.  Local gusty north winds are expected Saturday with light winds Sunday.

Tuesday and Wednesday a low pressure area will drop from Canada into Nevada (see map below).  The models vary on whether it will end up over Nevada or a little further west.  If it ends up over Nevada we will see another round of "PGE type" strong gusty north to northeast winds Tuesday through early Thursday.  The areas east of the Sierra Cascade Crest will see a few clouds Tuesday and early Wednesday.  Temperatures will drop back to near normal.

High pressure is firmly entrenched along the west coast.  Today and Tuesday look sunny with some high cloudiness.  The high will weaken a little late Wednesday and Thursday as a low pressure trough moves through the Pacific Northwest. This trough will bring increased mid and high clouds to our area with light showers possible on the north coast.   After the trough passes high pressure rebounds along the coast (see map below).  This means continued sunny skies.  Temperatures will be 15 to  20 degrees above normal today but will cool slowly during the week.  Winds will be light for the next week.

The hardest part of today's forecast is how to write the same thing I have written for the last week and make it sound different  High pressure is still along and off the west coast and as the map below shows will hold there through at least mid November.   Northern California will continue mostly clear.  Temperatures will be above normal and winds will be light.

Not much change.   High pressure continues along and over the west coast.  While the map below shows some weakening of the high it won't be enough to allow the jetstream to sink southward over Northern California.

The next week to 10 days looks mostly clear.   Temperatures start off 10 to 15 degrees above normal but will cool to 4 to 8 degrees above normal by the end of the week and the weekend.  Winds will be light.
