APPARENT TEMPERATURE is the perceived temperature in degrees Fahrenheit 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.

CATEGORICAL CONVECTIVE HAZARD OUTLOOK is a categorical forecast (slight, moderate, or high risk) that specifies the perceived level of threat of thunderstorms, severe thunderstorms, hail, damaging winds, and tornadoes.

HAZARDS are weather or hydrologic hazardous events issued for the protection of life and property and the enhancement of the national economy. For a specific list of hazards available through NDFD, see the Product Description Document entitled "Experimental Hazard Grids in the National Digital Forecast Database

PROBABILISTIC TROPICAL CYCLONE SURFACE WIND SPEED (CUMULATIVE) is the probability (in percent) of sustained surface wind speed greater than 34-, 50- and 64-knots (3 separate elements) sometime during the specified cumulative forecast period (0 – 6 hours, 0-12, 0-18, etc.) at each specific point. NOTE: This element is provided for coastal and inland points as well as offshore locations (e.g., buoys).

PROBABILISTIC TROPICAL CYCLONE SURFACE WIND SPEED (INCREMENTAL) is the probability (in percent) of sustained surface wind speed greater than 34-, 50-, and 64-knots (3 separate elements) sometime during the specified forecast period (0 - 6 hours, 6 -12, 12 -18, etc.) at each specific point. These values are incremental since they can increase in value by accounting for the possibility the event might start in an earlier period and still be occurring in the specified period. NOTE: This element is provided for coastal and inland points as well as offshore locations (e.g., buoys).

QUANTITATIVE PRECIPITATION FORECAST (QPF) is the expected amount of liquid precipitation (in hundredths of inches) accumulated over a six hourly period. A QPF will be specified when a measurable ( 1/100th of an inch or more) precipitation type is forecast for any hour during a QPF valid period. NDFD valid periods for QPF are 6 hours long beginning and ending at 0000, 0600, 1200 and 1800 UTC.

RELATIVE HUMIDITY is a ratio, expressed as a percent, of the amount of atmospheric moisture present relative to the amount that would be present if the air were saturated. Since the latter amount is dependent on temperature, relative humidity is a function of both moisture content and temperature.
