Mid-Atlantic Climate Impacts Summary and Outlook: Winter 2022–2023

MARISA Mid-Atlantic Regional Climate Summary map and title

The winter season was marked by warmer than normal temperatures and lower than average snowfall in the Mid-Atlantic region.

Most areas experienced temperatures 4–6 degrees above normal, while the southern half of the region saw less than a quarter of normal winter snowfall.

Explore an analysis of how the average number of days per year with cold low temperatures is projected to change in the future in the latest MARISA Seasonal Climate Impacts Summary and Outlook.

Highlights

Most areas experienced temperatures 4–6 degrees F above normal. We have not seen seasonal temperatures this far above normal for any season since the start of the MARISA climate summary series in Summer/Fall 2018.
The southern half of the region received less than 25 percent of normal winter season snowfall, with several sites hitting records for the least snowy winter on record.
Under a high emissions scenario, the average annual number of days with minimum temperatures below 20 degrees F in the Mid-Atlantic region are projected to decrease to about 14 days/year by late century, compared to 43 days per year between 1991–2020.

The MARISA Seasonal Climate Impacts Summary and Outlook is a seasonal series produced by NOAA’s Mid-Atlantic Regional Integrated Sciences and Assessments program that details seasonal weather and climate variability and change in the Mid-Atlantic region.

MARISA is led by the non-profit RAND Corporation, in partnership with researchers in Penn State University’s Earth and Environmental Systems Institute, Johns Hopkins University, the Department of Earth and Atmospheric Sciences at Cornell University, the Virginia Institute of Marine Science, Morgan State University, and Carnegie Mellon University.
