WeatherMatrix: U.S. Daily Weather Records

WeatherMatrix - 10,000 Weather Enthusiasts Can't Be Wrong!

WeatherMatrix is a worldwide organization of over 10,000 amateur and professional weather enthusiasts -- meteorologists, storm chasers and spotters, and weather observers from all parts of the globe. Online for 10 years, we are the largest online weather community.

The National Weather Service constantly outputs statements on record weather events, or "RER / Record Event Reports", which are tied or broken in the United States. Through WeatherMatirx, Internet users have access to a summary report issued each morning. We used to send the daily reports through the StormReports email list, before that list was discontinued. The latest summaries are shown below. More extreme weather information is avialable on our Extreme Weather page.

* = Disclaimers for statistics: Numbers are approximate due to random NWS formatting, random retransmission, corrections, and data delivery formats. Total may not equal parts due to multiple locations in one record report or improper formatting which causes records to not be extracted. Breakdown of record type only available after 8/22/2004. These totals are only available since 3/1/2003.

A More Accurate, But Less Available Source: Guy Walton at the Weather Channel maintains a more manual, scientific total number of records per year, and probably per day and month (reference). He does not make this information public on a routine basis (other than the yearly 2000-2005 records he published in WeatherWise Magazine) and he is not reachable over the Internet.

WeatherMatrix also provides an archive of U.S. Weather Records for the current month and has the information for 2003 available on CD-ROM.

The links shown above include the time, date, location and type of record broken. To see specific values of records broken, consult our monthly archive see the Recent Record Values section below.
