The day began with showers and rainbows, but precip quickly ended and so did the rainbows. Pleasant weather prevailed for the rest of the day with seasonably cool temps.
Pretty quiet evening as well. Sunset and lingering cumulus clouds faded. Clear skies prevail this evening. The big question for tonight will be, can enough radiational cooling occur before high clouds arrive? Latest satellite already shows some high clouds creeping in from the west. We'll be watching it closely. No update needed at this time,

An upper level low and associated cold front worked its way through the region this morning. Behind it a mix of Sun and clouds, with cool temperatures peaking in the 60s for interior valley locations, upper 50s to low 60s along the coast, and mid 50s to low 60s in the hills and mountains. As the sunsets, cumulus clouds should dissipate and onshore winds will ease. Guidance tonight shows high clouds moving in, which makes the forecast a bit interesting. Current thinking is that these will roll in and limit radiational cooling and radiational fog development. Kept the shot for patchy fog in the forecast for the interior valleys of the Bay Area, but it will be dependent on cloud cover and winds. High pressure continues to build in on Monday which will lead to slightly warmer temperatures and dry weather.

A quick moving shortwave trough will bring light rain to Bay Area and Santa Cruz on Tuesday, with perhaps some showers making into northern Monterey and San Benito counties. Rainfall amounts look to be light and generally around 0.15-0.40" for the North Bay, and 0.05- 0.25" for the San Francisco Peninsula, East Bay, and Santa Cruz, and around 0.0-0.10" for Santa Clara County. south of that amounts in Monterey and San Benito are generally a couple hundredths of an inch or less. Once the this shortwave moves through, we'll see a mix of zonal flow and ridging builds behind it. This will lead to a warming and drying trend through the week.
