Tule fog in the vicinity of the East Bay and southern Napa County is struggling to advance farther west where dewpoint depressions in lower lying areas remain around 5-10 degrees as of 3AM PST. High clouds have begun making their way inland on the subsident side of the amplified ridge axis just offshore and will continuing drifting over our area throughout the day. Although the synoptic ridging pattern across the west will persist into the beginning of the upcoming work week, we'll see a series of shortwave troughs interrupt the ridging at our latitude with little impact on our ambient weather conditions today and tonight. High temperatures today will be cooler than Saturday for the North Bay, Bay Area and East Bay with increasing mid/high level cloud cover and the weak offshore flow getting neutralized. Overnight lows into early Monday morning will also tick a few degrees warmer for most of our interior locations.

Modest increases in mid level heights and thickness will increase temperatures on Monday into the low to mid 60s for most of our area as the upper level ridging is reinvigorated through Tuesday. However, the reincarnated ridging on Tuesday is progressive. A deepening trough over the eastern Pacific in the wake of the ridging appears to lift north as it approaches the coast, with a trend toward less rainfall for our area Wednesday from the previous update Saturday afternoon. The longwave synoptic pattern remains active through the remainder of the extended forecast, especially for eastern CONUS, but the net result for the Bay Area and Central Coast is relatively quiet weather. There's a slight chance for some light amounts of beneficial rain next weekend.
