I mentioned earlier today that my friend Jan Null, former lead forecaster for the NWS in San Francisco and now operator of Golden Gate Weather Service pointed out that a number of cold records were set overnight. Looks like we are in for a second night, and it looks even colder for some areas. Napa’s wine valley may hit 26-27 tonight. 2011 may not be a good year for wine then. We’ll see. Other grape growing areas in coastal valleys will also be affected:
Here’s the official record reports:

Here’s the forecast for Saint Helena in the center of the Napa Valley tonight, they call for 26 degrees.
Growing areas near Salinas will also get a frost.
