Temperature & Precipitation

Air temperature and precipitation can have wide-ranging effects on natural processes, and their datasets are foundational for drought and climate analysis. Changes in temperature and precipitation can substantially disrupt crops and livestock, influence the frequency and intensity of severe weather events, and affect the quality and quantity of water available for municipal and industrial use.

    • Temperature and Precipitation Measurements

    Temperature and precipitation data are collected from weather stations, weather radar, satellites, and computer models.

    Warmer air temperatures increase evapotranspiration—which is the combination of evaporation from the soil and bodies of water and transpiration from plants—and lower soil moisture.

    Drought is defined as the lack of precipitation over an extended period of time, usually for a season or more, that results in a water shortage.

    Data, Maps, and Tools

    To make data easier to use, many organizations derive products from raw data. These derived products may start with station data, which estimate (or interpolate) the information between stations using different methodologies. Radar- and satellite-based products may include station data as “ground truth” to remove bias and create more accurate products.

    Temperature and Precipitation Outlooks

    CPC Temperature Outlooks

    6–10 Day One Month Three Month

    The National Weather Service's Climate Prediction Center (CPC) produces temperature outlooks for the U.S., including 6–10 day, 8–14 day, monthly, and seasonal outlooks. The outlooks depict whether there is a greater chance for above-normal, below-normal, or near-normal conditions during the noted time frame. Learn more.
