Average thunderstorm days for each month How can I find the average number of days with thunderstorms for each month for different cities in the United States? I’m doing a researching project for this and I need to find some links that will show me the average number of days with thunderstorms for each month for different cities in the United States.
You should start with NOAA services. They have a Storm Events Database going back to 1950, where you can do queries for states/counties of interest. If you are more interested in lightning data, they also have some products, including raw data from a private company (you'll need access for this) and freely available derived products.
