Satellite imagery this morning shows the cold front south of Monterey and San Benito counties this morning, working its way through SLO and towards southern CA. There are a few lingering showers, mainly over over our waters, though a few reflectivites can be seen skirting the Big Sur coast and over interior Monterey County. Expecting drier conditions for the afternoon, with high temperatures making into the low to mid 60s for most interior valleys, the upper 50s to low 60s along the coast, and perhaps only into the upper 40s to mid 50s in the higher elevations of the region.

Popcorn shower activity focused over the interior CEntral Coast earlier in the nigh has since faded or moved eastward into the Central.
Focus quickly turns westward as a low pressure is now entering the northern coastal waters. The low pressure system and associated frontal boundaries are producing showers and isolated thunderstorms. KMUX radar even picked up some weak rotation with the stronger cells, but they're pulsing on any rotation. Environmental parameters show less instability and shear are present the closer one gets toward the coastline. As such, expect the shower activity to hold together into Sunday mid- morning, but not expecting any thunderstorms over land. By Sunday afternoon any showers will end with increasing sunshine. Rainfall amounts will be a trace to 0.25". Winds increase by the low pressure/cold front with breezy conditions at the coast.
Coastal flooding remains possible along the bayshore locations of the San Francisco, San Pablo, and Monterey Bays through Sunday at 6 PM PST.
Tonight through Monday - Winds ease overnight with clearing skies. Given the recent rain, decreasing winds, and clearing skies patchy fog is possible Monday morning. Warmer and drier conditions to kick off the work week.

Upper level ridge moves eastward as another upper level low/trough takes aim at the Bay Area Tuesday. As such, the next round of rain, albeit light, will move Tuesday and Tuesday night. Rainfall amounts with this system will be greatest over the North Bay with amounts 0.10-0.30", Bay Area is less than 0.10", and Central Coast is trace to nothing.
Thereafter, zonal flow to ridging develops by Wednesday and continues into next weekend. If the forecast holds, temperatures will return to the 70s by Friday possibly a few low 80s interior on Saturday.

Satellite imagery shows VFR conditions, the cold front out of our region, and cumulus clouds left in its wake mainly south of the North Bay and most prevalent over the terrain. A few isolated showers remain over the waters, though a few may skirt along the Big Sur coastline through the early afternoon. Expect onshore winds for much of the region, with winds becoming light and southerly to variable overnight. Generally think VFR conditions should prevail, with some high clouds trying to sneak in early Monday morning. Should we keep enough breaks in the clouds, or they don't manifest, we could see some pockets of fog in the North Bay valleys. Moderate to high confidence in the forecast.
Vicinity of SFO, Generally VFR conditions should prevail around SFO, with some cumulus clouds bubbling up along the nearby terrain. Winds should switch onshore by the afternoon, with perhaps a few gusts to 20-23kt this afternoon. Winds decrease after sunset, cumulus clouds should dissipate, with weak onshore flow overnight. Winds should shift to the south early Monday morning. Moderate to high confidence in the forecast.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, Mainly VFR conditions should prevail today, as northwest winds lead to lingering cu over the region. Showers should hold for a few hours over the coastal waters, and may skirt the Big Sur Coastline. Otherwise dry conditions prevail and onshore winds return this afternoon. We may see some gusts to 15-20kt around KMRY and KSNS through the early evening. Winds then weaken, with south to southeast flow expected by Monday morning. Moderate to high confidence in the forecast.

Gentle to moderate breezes and moderate seas will prevail, building to become rough in the outer waters Tuesday into Wednesday.
