Time series of temperature data?

Hi all,

Where do I get time series of temperature data of a city, say San Francisco?

Thanks!

 

See attached file.

Also Jim Simons has several times claimed Rentec has tested temperature series as indicators.

Any more specific instructions?

I saw a bunch of big raw text file...

I want to find weather time series for an arbitrary city in the US.

Thanks
