They were right: It got even colder Thursday morning, with temperatures dropping into the teens in some areas of the North Bay as a cold front that blew in earlier in the week continued its winterizing work.
The frosty morning brought warnings of black ice on local roadways and sent homeless people to warming stations by the dozens.
Graton was among the cold spots, posting 19 degrees at sunrise, with Occidental close behind at 20, the National Weather Service said.

Elsewhere, early morning reports included 22 degrees in Petaluma and Healdsburg, 19 at the Napa County airport, and 26 at the Charles M. Schulz-Sonoma County Airport, meteorologist Austin Cross said.
Official low temperatures from overnight were not yet available, but it appeared Santa Rosa, at least, might have come in at just above the record 24 degrees on Dec. 5, 1972.
But in some places “we are breaking 1972 records,” Cross said, “like down in San Rafael it got down to 30, which beats the old record of 31.”
At the Homeless Services Center run by Catholic Charities, about 35 people sought refuge through the night after organizers and close to a dozen last-minute volunteers set up warming stations at the Morgan Street drop-in center, said Jennilynn Holmes, the agency's director of shelter and housing services.
“We expect about double that tonight,” Holmes said.
The organization set up canopies and heaters, and donors came by with sleeping bags, jackets, gloves, warm socks and other items, more of which are still needed, Holmes said.
“We're just trying to keep people alive,” she said.
Anyone with donations they would like to contribute can contact Holmes at her office, (707) 542-5426.
