Under a higher emissions pathway, historically unprecedented warming is projected by the end of the 21st century. Extreme heat is of particular concern for densely populated urban areas (such as where high temperatures and high humidity can cause dangerous heat index values. Observed data are for 1900– 2014.

Excessive Heat Warning: (See a map of Excessive Heat Warning Criteria) Excessive Heat Watch: Possibility that Excessive Heat Warning Criteria may be met at longer ranges (12 to 48 hrs out). For an outlook beyond 3-4 days, see the extended heat index guidance we get from the NWS's Hydrometeorological Prediction Center (HPC): Note that maximum heat index data are sparse. Heat index data are recorded only for days when the air temperature is above 80 degrees Fahrenheit (26.7 degrees Celsius). See Additional Information for more information about heat index data. These daily mean, minimum, and maximum heat index products are guidance products. Official forecasts of instantaneous apparent temperatures (e.g., heat index or wind chill) are displayed on the National Weather Service web page. Definition of Heat Index: The heat index is an estimate of how hot the air “feels” to the human body and provides a relative indication of potential health risks. Among others, the two primary factors in the heat index equations are temperature and water vapor (i.e., moisture/humidity). Reported measures are the average temperature, number of observations, and range for the daily maximum and minimum air temperatures, and also percent coverage for the daily maximum heat index. Data are available by place (combined 48 contiguous states, region, division, state, county), time (year, month, day) and specified maximum and minimum air temperature, and heat index value. Reported measures are the average temperature, number of observations, and range for the daily maximum and minimum air temperatures, and also percent coverage for the daily maximum heat index.
