Mouseover the numbers above to show a list below. Keep in mind that this display shows the number of (usually major) cities that are forecast to be near (by <1°F), tie, or break the record. There are 368 stations in the CONUS database as of April 2019. Data updated through 12/31/2018.
These graphics use the latest National Digital Forecast Database (NDFD) grids and compare to the record database (from ThreadEx). Stations within 1°F of a record are plotted.
Images load about 45 minutes after the cycle (i.e., 12Z cycle data loads around 1245Z). What is Z time?
