An upper level low is slowly moving eastward well South of us.  A surface frontal system is moving Southeastward through California, but another upper level low will show up  so there will be at least a chance of precipitation for the next 7 days, but the chances will be quite low. Wednesday will see another frontal system taking the same course and by Thursday it will be past us.

Advisories: NONE AT THIS TIME.
