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 ~390 stations in the CONUS database as of 2025. Data updated through 12/31/2024. These graphics use the latest (00Z/06Z/12Z/18Z) National Digital Forecast Database (NDFD) grids and compare to the record database (from ThreadEx).

Stations within 1°F of a record are plotted. Please note that minimum temperatures are forecast for the morning hours but the records encompass the entire calendar day; therefore, the low temperature for the day may occur just before midnight and may be...

The National Digital Forecast Database (NDFD) is a suite of gridded forecasts of sensible weather elements (e.g., cloud cover, maximum temperature).

NWS field offices working in collaboration with the National Centers for Environmental Prediction (NCEP) are combined in the NDFD to create a seamless mosaic of digital forecasts. Access to NDFD Data via ftp and https in GRIB format. Access to NDFD Data via SOAP and REST in XML. Tools for viewing NDFD Data in graphical form. Information and support tools for using NDFD Data. The National Digital Forecast Database (NDFD) is a suite of products generated by the National Weather Service (NWS) using data from regional NWS Weather Forecast Offices (WFOs) and the National Centers for Environmental Prediction...

The database provides access to forecasts produced at WFOs, as well as NCEP gridded model data enhanced by WFO staff. The NWS uses these products to make text, graphic, and digital products for emergency managers and the public. The NDFD also provides data for commercial weather companies to generate their own products based on NWS forecasts. NDFD products are available through NCEI model data services. For data prior to October 6, 2008 use the NCEI Archive Information Request System (AIRS). Requests are limited to one day’s worth of data at a time due to size and processing requirements.

AIRS access is recommended for users wanting to obtain many days of NDFD data. The NOAA Big Data Program also provides access to NDFD data from April 16, 2020 to present organized by WMO element in the AWS Open Data Registry for NDFD. The National Digital Forecast Database (NDFD) Web Services provide a set of gridded weather forecasts for various sensible weather elements in near real-time. These forecasts are generated by a collaboration between the National Weather Service (NWS) field offices and the National Centers for Environmental Prediction (NCEP). The NDFD Web Services offer a seamless, digital mosaic of weather forecasts that can be accessed by users to obtain up-to-date information on a variety of weather conditions. The NDFD's forecasts are gridded, meaning they cover large geographic areas with weather data at specific intervals, providing high-resolution, geographically distributed forecasts.

These forecasts can include temperature, precipitation, wind speed and direction, cloud cover, and other meteorological parameters. These web services are hosted by the Office of Dissemination’s CloudGIS team, which ensures the forecasts are readily accessible and deliverable over the internet. Users, including meteorologists, developers, and anyone interested in weather data, can query these web services for up-to-date forecasts in a digital format, enabling integration into applications, websites, and other platforms. 12-Hour Probability of Precipitation Web Service's data layer is the likelihood, expressed as a percent, of a measurable precipitation event (1/100th of an inch or more) at a grid point during the 12-hour valid... The 12-hour valid periods begin and end at 0000 and 1200 Coordinated Universal Time (UTC). Apparent Temperature Web Service: contains data that is the perceived temperature derived from either a combination of temperature and wind (Wind Chill) or temperature and humidity (Heat Index) for the indicated hour.

When the temperature at a particular grid point falls to 50 F or less, wind chill will be used for that point for the Apparent Temperature. When the temperature at a grid point rises above 80 F, the heat index will be used for Apparent Temperature. Between 51 and 80 F, the Apparent Temperature will be the ambient air temperature.
