This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.

Ref comment from Mark.  The standard computer models show forecast skill out to 7 to 10.  There are some "climat" models that are run weekly or monthly.   I will try to include info from them when available. 

The high pressure continues with little change expected through the weekend (see map below).  It looks like the high will weaken a little next week.  The inland areas of Northern California will remain sunny with some afternoon cumulus clouds over the mountains.  There is a chance of isolated thunderstorms today and Thursday over Siskiyou, Modoc, and Lassen counties.  Hottest days will be Thursday and Friday when temperatures will be 10 to 15 degrees above normal.  Today and the weekend temps will be 6 to 12 degrees above normal.  Next week we should be 2 to 4 degrees above normal. Winds will be light. 

The longer range models I mentioned above show some cooling or continued weakening of the high pressure area the first week of August.   However, they do keep the high centered over the west through the month.
