History of WFO Cleveland's Climate Sites

ThreadEx, which stands for Threaded Extremes, takes the maximum and minimum temperature and daily total precipitation recorded at the National Weather Service Automated Surface Observing Stations (ASOS) and pieces it together with other historical data nearby to create a single, long-term set of daily weather information. This includes all of NWS Cleveland's climate sites, which have had the ASOS moved at times. Below is the outlined station history of each climate site, but remember that ultimately all the data is 'threaded' to give us the current climate database!
