Mother Nature flocked much of the North Bay early Sunday, leaving a frosty white coating on everything from Christmas tree farms and vineyards in the county to residential yards and parked cars in the cities.

Temperatures were in the low 20s in many areas of the region, enough to freeze and burst some water pipes but not set any local records.

Santa Rosa's morning low downtown Sunday was 24.

The record remains at 21 degrees, set on a frightfully frigid Jan. 13, 1949, and again in 2007.

The Charles M. Schulz-Sonoma County Airport reported 23 degrees Sunday, and that wasn't a record either.

The mercury hit 23 in Sonoma, 22 in Petaluma and a balmy 31 on the coast in Bodega Bay. Farther north, Middleton reached 20 degrees and Ukiah 24.

Fire dispatchers heard of a few broken water pipes and several frozen ones. The CHP early Sunday reported that a broken pipe north of Bodega Bay had created an icy roadway, but knew of no crashes.

The big chill is due to continue until Thursday, when morning temperatures should creep up into the 30s and the afternoon should reach the low 60s, according to the National Weather Service.
