...Discussion from SFOFWFMTR...

Upper level ridging and high pressure keep the  upcoming forecast
relatively stable through the remainder of the  week. Foggy
conditions overnight/morning conditions remain likely  for the North
Bay and East Bay as Tule Fog is advected in from the Central Valley.
Coastal stratus and fog remain possible as a  shallow (500 ft)
marine layer attempts to redevelop by late this  week. Light,
offshore winds continue through the rest of this week with hazy
conditions expected across the interior.


...Discussion from SFOFWFEKA...

High pressure ridging will be the prevailing  pattern well into the
week. A stationary frontal system further north will periodically
clip Northern CA this week could bringing light precipitation to Del
Norte & northern Humboldt counties. A  warming trend with light
winds and morning valley fog expected  elsewhere this week.
