Napa, CA – As Northern California enters the new week, residents can expect a warming trend to continue, according to the National Weather Service. Forecasters from the NWS San Francisco office reported Sunday that “quiet weather is on tap” for the region, with above-average temperatures beginning Monday and lasting through midweek.

A brief cooling trend is anticipated by Thursday or Friday, but temperatures are expected to rise again heading into the weekend. The dry and stable conditions come as the Bay Area and surrounding regions grapple with a series of troubling developments from the weekend.

Mass Shooting Near High School Injures Six

Authorities are investigating a mass shooting that left six people wounded near a Northern California high school on Saturday. Law enforcement officials have not released information regarding suspects or possible motives, but say the incident is part of a growing concern over gun violence in the region.

Witnesses reported chaos near the school as multiple gunshots rang out during what appeared to be a public gathering. Emergency crews transported several victims to nearby hospitals. Their conditions remain unknown as of Monday morning.

Police Shooting in East Bay Sends One to Hospital

Separately, an officer-involved shooting in the East Bay sent one individual to the hospital over the weekend. The incident occurred during a police response in a residential neighborhood. Details remain limited, but authorities confirmed the person shot was taken to the hospital with non-life-threatening injuries.

An internal investigation is underway, and the department has pledged transparency as it gathers more information.

3D-Printed Firearms Found in Bay Area Home

In another alarming case, a man on probation was arrested after police uncovered a cache of 3D-printed firearms inside his Bay Area residence. Investigators say the weapons were “fully functional” and potentially untraceable, raising fresh concerns about so-called “ghost guns” — firearms manufactured without serial numbers.

Officials have not released the suspect’s name but confirmed charges are pending. The discovery comes amid a broader national debate over the regulation of homemade weapons.

Gray Whale Deaths Along California Coast Spark Concern

Meanwhile, environmentalists and marine biologists are expressing concern over the growing number of gray whale deaths along the California coast. At least 80 gray whales have died in Mexican waters since the beginning of the year. In Northern California, three whales were found dead in San Francisco Bay in recent weeks.

Over the weekend, another dead whale washed ashore in Southern California, adding to what scientists are calling a “worrying trend.”

The cause of death in many cases remains unclear, though experts suspect a combination of malnutrition, changing ocean conditions, and ship strikes could be contributing factors. The National Oceanic and Atmospheric Administration (NOAA) has launched an investigation and is urging boaters and coastal observers to report any sightings of distressed or deceased whales.

As the week begins, Northern California residents face not only a shift in the weather, but the lingering impact of violence, legal challenges, and environmental warnings — all part of a rapidly changing landscape across the state.
