SEBASTOPOL (CBS SF) – A KPIX Weather Watcher spotted a funnel cloud from Sebastopol Thursday morning.

Kathy Munch saw the cloud as she walked out her door at 5:54 a.m. She was looking north towards Lake Sonoma.

“With the viewer reporting rotation, we feel that it is suspicious and possibly a funnel,” National Weather Service meteorologist Charles Bell said. “If it is actually a funnel, it would be very weak.”

KPIX Weather Anchor Roberta Gonzales checked the cloud with radar at the time and discovered there was a band of light rain moving through the area. “I realized it was certainly possible the cloud would classify as a funnel cloud,” she said.

The photo was submitted to the National Weather Service for further review and Gonzales says it has since been classified as a very weak funnel.

Later Thursday there is a strong possibility of isolated thunderstorms containing hail and lightning in the Bay Area, especially this afternoon. The KPIX 5 newsroom received several reports of hail in the Fremont area Thursday morning.
