The National Weather Service says the pattern of cold nights and warming days will continue today and Monday.
"Little change in conditions is expected the next few days with cold nights and warm daytime highs," the weather service reports.
It attributes that to a high pressure ridge over the region - one that likely will translate into patches of fog near waterways in the central valley in the morning.
A new weather system is approaching from the west and will push the current ridge in Northern California east. But that isn't likely to change the weather that much, the weather service says. By Wednesday, there is a possibility of light precipitation north of Sacramento. The weather service says night time lows should be warmer.
