Patchy thick inland fog coupled with cold temps in the 20s and 30s inland started the day, with more mild 40s closer to the inner bay. Low clouds and fog will likely linger around the North and East Bay valleys through midday keeping daytime temps in the near 50 to mid 50s range with other areas that woke up without low clouds like San Jose, should see highs closer to 60 during the afternoon. Patchy low clouds and fog will fill in again for Sunday night with air quality also being an issue. A Spare The Air alert is in effect for Sunday and could very well be carried into Monday as well. Dry weather is expected to rule the week with a fairly weak system tossing some showers possibly down the northern coastline on Thursday, but likely leaving the Bay Area dry. Winds may briefly kick in again behind this system on Christmas Eve with more dry weather expected for the rest of the holiday weekend.Enjoy your Sunday! - Rob Mayeda
Weather conditions forecast for Monday are expected to create unhealthy air quality in the Bay Area, prompting a local agency to proclaim season's seventh Winter Spare the Air Day.
The Bay Area Air Quality Management District announced Sunday that wood burning, both indoors and outdoors, will be illegal on Monday.
District officials said that the cold, still weather patterns returning to the Bay Area traps pollution close to the ground under a layer of warmer air. During winter months, wood smoke is the leading cause of wintertime air pollution in the Bay Area, according to district officials.
Wood smoke contains harmful pollutants, such as soot and carbon monoxide, and toxins such as dioxin, which has been linked to increased cancer rates in adults.
About one-third of the harmful soot in the winter air can be attributed to wood smoke from the roughly 1.4 million fireplaces and wood stoves in the Bay Area, according to the district.
More information about the ban can be found at www.sparetheair.org or by calling (877) 4NO-BURN (466-2876). Those wishing to receive automatic phone calls when a Winter Spare the Air alert is issued can register for the alerts by calling (800) 430-1515.
