New Products

WeatherARC is looking to add some new products and redesign the website a little bit. They have also just begun to offer certified weather data services should you need certified weather reports. Check the site out in the next several weeks to see the upcoming changes. Why don't you bookmark the page while you are there?

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.

Record Rainfall for Seattle - October 2003

I was going through some temperature data and saw abnormally high rainfall totals for the month of October in 2003 for Seattle Washington (almost 9 inches fell during the entire month). Look at the graph below to see what I am talking about:

What was the weather like?

What was the weather like on a specific day in the past? What was the weather on my birthday? WeatherARC has all of that information and more available.

Weather data for many locations is available back to 1931 for some locations.

If you are interested in upper air data or simply surface data you can find it on the WeatherARC site. You can also find definitions for things like temperature, degree days, wind, dewpoint, relative humidity, precipitation, and atmospheric pressure by going here.

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.
