DISCUSSION:

A dry weather pattern will continue through today, then shower
chances will increase along the Central Coast tonight through
Wednesday. On Wednesday, the tail end of a weakening atmospheric
river will likely bring rain to the Central Coast. Rainfall amounts
will mostly be under a tenth of an inch or less through Wednesday
night, except a quarter to three quarters of an inch of rain in
northwest San Luis Obispo County. There is a 10 to 15 percent chance
of amounts over an inch in northwest San Luis Obispo County.

There is a high potential for widespread rain at some point after
next Tuesday. There is a 30 percent chance of impacts associated
with periods of moderate to heavy rainfall. Peak timing of the rain
looks to fall sometime between Wednesday and Friday (11/12-14).
While early, initial estimates appears to place amounts between one
and two inches across the coastal and valley areas.
