These records are based on the historical daily observations archived in NCDC's Cooperative Summary of the Day data set and preliminary reports from Cooperative Observers and First Order National Weather Service stations, and as such are subject to change. All data in this database is "preliminary". This list may not representing all stations that set a record on any given day. Many stations do not report in real-time, and quality control methods on this dataset are not as complete as the final quality-controlled U.S. Historical Climatology Network dataset. The actual number of records set on a given day, in any category, is likely larger than depicted here. The Period of Record (POR) represents the number of years with a minimum of 50% data completeness. All stations have a Period of Record of at least 30 years. When the 6-digit COOP ID does not exist for a station the 5-digit WBAN ID is used.
