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 350 stations in the CONUS database as of May 2018. Data updated through 12/31/2017.
These graphics use the latest NDFD grids and compare to the record database (from ThreadEx). Stations within 1°F of a record are plotted.
Images load about 60 minutes after the cycle (i.e., 12Z cycle data loads around 13Z).
