AccuWeather forecast: Cool weekend, drizzle in parts of Bay Area, chance of showers in Sonoma Co.

It's a cool weekend with afternoon highs well below average accompanied by morning patchy mist, drizzle both today and Sunday.

A system from the north will bring a chance of showers or thunderstorm to Sonoma County today. A deep marine layer & accumulated precipitation up to a tenth or two tenths of an inch of rain is possible near the coastal hills. This area of low pressure will allow highs to only reach the low 70s in our warmest inland valleys.

This system heads into Southern California tomorrow, but the weather looks pretty similar to round out the weekend. Bundle up!

After a brief warmup to start the work week another trough cools us down midweek.

The good news is that there won't be any fire concerns for the next seven days!
