National Weather Service San Francisco CA 843am PST Sat Dec 2 2023
Issued at 233am PST Sat Dec 2 2023
Cool, unsettled weather for the next few days followed by a warming trend into early next week. An approaching trough of low pressure towards the middle of the upcoming week will bring the return of unsettled weather.
Issued at 842am PST Sat Dec 2 2023
Dreary start to your Saturday with a mix of sun/clouds, cool/damp conditions and scattered showers. KMUX radar, located in the Santa Cruz Mts, continues to show widely scattered showers moving through the Bay Area and Central Coast. Rainfall amounts over the last six hours range greatly - trace to no precipitation South Bay southward to a few hundredths Santa Cruz Mts/San Francisco Bay northward. Current forecast calls for lingering showers through out the day and see no reason to update the forecast. While today will not be a wash out, hit or miss showers will be possible. Additional rainfall today will be on par with the last six hours - a few hundredths to maybe a tenth with a stronger showers.
.SHORT TERM... (Today and tonight) Issued at 233am PST Sat Dec 2 2023
Isolated showers are moving across the region this morning mainly across the North Bay, San Francisco Bay Area
and down into the Santa Cruz Mountains. They may reach the Central Coast late this morning, but amounts are anticipated to be light. By this afternoon, the focus for additional precipitation will shift north across the North Bay.
Another cool afternoon is in store with temperatures struggle to warm much beyond the mid 60s across the interior, upper 50s elsewhere and upper 40s to lower 50s in the highest peaks. Tonight, look for temperatures to cool into the lower 50s in the hills and around the San Francisco Bay Shoreline to the mid 40s elsewhere.
(Sunday through Friday) Issued at 233am PST Sat Dec 2 2023
A subtle warming trend will get underway on Sunday and then become more robust Monday into Tuesday. By Monday the interior is expected to reach the lower 70s and mid 70s by Tuesday. This warm up will be short-lived as the next mid/upper level trough approaches the West Coast.
Cooling will take place on Wednesday across the North Bay while mild conditions prevail over the Central Coast. This is when/where precipitation chances increase late Tuesday night into Wednesday. Cool, unsettled weather will continue into Friday.
Once the precipitation tapers off on Friday the focus then turns to overnight lows. Longer range guidance suggests another round of chilly to cold night with frost/freeze conditions possible.
(Today through Thursday) Issued at 233am PST Sat Dec 2 2023
Gentle to moderate westerly breezes continue through the weekend with chance for rain across the northern waters. Northwest swell will build today into Sunday, resulting in elevated seas of 8 to 10 feet that will be hazardous to small craft across the northern waters. A series of larger northwest swells with a 16-20 second period will result in a continuation of elevated and hazardous seas through much of the upcoming week.
