An upper level disturbance passes over the region today which brought isolated rain showers this morning and left cloudy skies for the afternoon. Weak upper level high pressure builds over the intermountain west today, while a deep upper level low from the Gulf of Alaska digs into the Eastern Pacific. Flow becomes a bit more zonal on Saturday, which may lead to showers skirting portions of Sonoma County and a mix of Sun and clouds throughout the rest of the area.

Upper level ridging builds over the Desert Southwest, nudging the aforementioned upper level low to the north some. This should keep much of the region dry on Sunday, with rain chances being confined to the North Bay. This patter looks to hold until Monday, before the ridge flattens and the flow becomes more zonal. The upper level will tap into some tropical moisture, fueling our early-mid week rain and wind. Thankfully, the system doesn't look to stall in any regions, which will alleviating a pro-longed flood concern. Given recent rains, shallow landslides are possible as well as minor flooding of low-lying, poor drainage, and urban areas. Ponding of water and slick roadways are a guarantee. Mainstem river flooding is not expected with a low probability (less than 20%) of occurrence. Saturated soils, mean there is also a chance for downed trees with any stronger gusts.
