Mid-Atlantic Climate Data Tools

The following data tools were produced as part of the Mid-Atlantic Climate Impacts Summary and Outlook, a quarterly series that details seasonal weather and climate variability and change in the Mid-Atlantic region. Review the full list of climate summaries.

Precipitation

  • A screen capture of a map tool showing a heat map of the Mid-Atlantic region, displaying projected data on longest stretches of dry days.

    Longest Annual Stretch of Dry Days

    An interactive data tool that presents an analysis of historical and projected consecutive dry days in the Mid-Atlantic.

  • A screen capture of a data tool with lines of colored bars representing projected changes in total monthly precipitation.

    Projected Changes in Total Monthly Precipitation

    An interactive data tool showing how total monthly precipitation is projected to change in the future compared to an historical baseline (1950–2020), and climate normal (1991–2020).

  • A screen capture of a data tool showing projected difference from 'normal' total annual precipitation in the Mid-Atlantic region.

    Differences from "Normal" Total Annual Precipitation

    An interactive data tool exploring how the changing definition of a climate normal affects our interpretation of projected future average precipitation.

  • Changes in Seasonal Total Precipitation from 1976 to Present – Bar Chart

    This tool uses an interactive bar chart to provide city, county, state or watershed-level estimates of how winter, spring, summer and fall total precipitation from 1976 to 2017 compare to a historic 30-year average (1976-2005) of total precipitation for each season.

  • Changes in Future Seasonal Total Precipitation – Bar Chart

    This tool uses an interactive bar chart to provide city, county, state or watershed-level estimates of how projections of winter, spring, summer and fall total precipitation from 2020 to 2095, under two future emissions scenarios, compare to a historic 30-year average (1976-2005) of total precipitation for each season.

  • Changes in Seasonal Total Precipitation from 1976 to Present – Chesapeake Bay Map

    This tool is an interactive map of the Chesapeake Bay watershed that provides gridded estimates of how winter, spring, summer and fall total precipitation from 2006 to 2017 compare to a historic 30-year average (1976-2005) of total precipitation for each season.

  • Changes in Future Seasonal Total Precipitation – Chesapeake Bay Map

    This tool is an interactive map of the Chesapeake Bay watershed that provides gridded estimates of how projections of winter, spring, summer and fall total precipitation during 30-year periods (2006-2035, 2036-2065, 2066-2095), under two future emissions scenarios, compare to a historic 30-year average (1976-2005) of total precipitation for each season.

    Mar 25, 2019

  • Changes in Extreme Precipitation from 1976 to Present

    This tool is an interactive map of the Chesapeake Bay watershed that provides gridded estimates of how extreme precipitation - the number of days each year with precipitation above a 1", 2" or 3" threshold - from 2006-2017 has changed compared to a historic 30-year average (1976-2005).

  • Changes in Future Extreme Precipitation

    This tool is an interactive map of the Chesapeake Bay watershed that provides gridded estimates of how projections of future extreme precipitation—the number of days each year with precipitation above a 1", 2" or 3" threshold—during 30-year periods (2006-2035, 2036-2065, 2066-2095) and under two future emissions scenarios, compare to a historic 30-year average (1976-2005).
