The only story in the West of big importance weather-wise is the impending chance of rain next week over much of California. An early season closed low will bring the chance of some rain for much of central and Southern California for at least several days next week along with temperatures well-below normal.
The ideas remain the same from my two previous posts. I am not going to rehash what I have been saying. I do want to give you a visual look at each day Monday through Thursday next week to show you the stability of the REX block. Because we cannot redistribute the European model data in graphical form, and the fact that there really is no important large-scale differences between it and the GFS, I give you the 500 mb graphics from the 12Z run of the GFS for each day.
As with any closed low where precipitation occurs, it is very hard to forecast even a day or two out. It is obvious that there is a good chance for scattered showers, and even a thundershower, somewhere around this closed low each day. It is also likely in this pattern that temperatures will stay well below normal for some time to come.
This storm is going to bring about accumulating snow to places that don’t see it often.
In the citrus areas from the San Joaquin Valley to northern Ventura County expect a hard freeze in most area
a well established spoke of energy rotated northeast and is bringing some areas a LOT more rain than the sprinkle or light shower I predicted.
It looks like the Cascades of Washington will get some important snow Sunday and Monday.
Southern California looks like it will get wet Thanksgiving and Black Friday.
The storm dropping south off the southern California coast tonight and parked nearly stationary Friday into Saturday brings a high chance of flooding problems
