2009 Rainfall to Date in California

*UPDATE* Rainfall totals for January 18-20, 2010 are available:
http://weatherarc.com/blog/2010/01/21/california-rains/

Here are some 2009 rainfall totals for several locations in California. These rainfall totals are for all rain that fell from January 1, 2009 to March 7, 2009. I have additional statistics for other cities in California if you are interested; I also have more recent rainfall totals if you need them. Please leave a comment and I will see what I can do. These statistics are provided courtesy of WeatherARC.

The cities are ordered by population with Los Angeles having the highest population. It would be interesting to see if there is a correlation between the location of the city within California and the rainfall amounts.

Archived Weather Data

Hello!

I know it can be very hard to find archived weather data online. Wouldn't it be nice to go to one website and get all of the archived weather data you need? There is a great site, called WeatherARC, that has both archived upper air and surface observations for many stations across the United States. More stations and more data are being added every day. Getting the data is easy and quick, whether you want data for one station or several stations. Go check it out at www.weatherarc.com.
