CA-CNR Weather


#1

Looking out to next week, the GFS has been consistent in showing a strong ridge of HP developing in the wake of a small system passing through far Northern California/Southern Oregon( Jefferson). The HP ridge looks to dominate the weather between Tuesday-Saturday of next week. If the model is correct , there could be an extended period of offshore flow, with some strong winds around the 30/31 time frame. I would expect that this could become a “high risk” event for PDS.
Would be interested to see what some of the weather folks think.


#2

Some high risk days have been added for NOP’s.

28%20AM


#3

Lots of high risk on today’s outlook.


#4

Red Flag today (10/28) for parts of Sierra’s


#5

Should be an interesting week for most of the state. Long lived offshore wind event, with a possible re-load next weekend.
Weak to moderate SA event taking shape for much of Socal, and warm temps. Main issue looks to be a long termed event.
For North Ops, another long termed event, with some moderate winds and potentially stronger gusts at night.
