A storm that moved in late Sunday is expected to be slow-paced as low pressure near the coast slowly moves to our south, producing rain through Wednesday before clearing out.  

The valley and delta are in a Flood Watch from Sunday afternoon through Wednesday morning. 

Monday saw a slight chance of isolated tornadoes across portions of the Sacramento Valley and Central Valley, including Sacramento, Stockton, Modesto, Yuba City, Roseville and Elk Grove. 

More showers arrived on Tuesday, with thundershowers forecasted in the afternoon. Gusty winds, small hail, and localized flooding were all possible impacts.
