San Francisco Bay Area/Monterey, California

New SHORT TERM, LONG TERM

• Minor coastal flooding at high tide for Bayshore through the Sunday
• Hazardous Beach Conditions Monday and Tuesday
• Seasonal to slightly below seasonal temperatures through Thursday
• Potential for light rain Tuesday

(Tonight through Monday)

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.

(Monday night through next Saturday)

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.

Currently VFR. Rain showers are approaching from the west and will spread from northwest to southeast between now and 14Z. Low-end VFR ceilings with brief reductions to MVFR ceilings and visibilities can be expected with rain shower activity. Low probability for thunderstorms with the best chances over the waters and to the east of our area. After the cold front passes, skies will clear and winds will increase.

Vicinity of SFO...Currently VFR with southerly flow. Rain showers are approaching from the west and will likely arrive between 08Z and 09Z with activity diminishing between 13Z and 14Z. Brief reductions in ceiling and visibility can be expected, likely in the MVFR category. After the rain showers pass, skies will clear and westerly winds will increase.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR with southerly flow at MRY and VFR with westerly flow at SNS. Low-end VFR ceilings are expected through mid-morning tomorrow. Rain showers are approaching from the west and will likely arrive between 10Z and 11Z with activity diminishing between 13Z and 14Z. After the rain showers pass, skies will clear and drainage winds may briefly return before onshore winds increase late this morning.

Unsettled weather is possible over the waters tonight through early Sunday with scattered showers and isolated thunderstorms. Otherwise, northwest gentle to moderate breezes and moderate seas will persist through the early next week. By mid- week, northwest winds increase to fresh with building rough seas across the outer waters. A long period southerly swell remains this weekend and combines with a long period northwesterly swell on Monday.
