Mid-Atlantic Climate Impacts Summary and Outlook: Spring 2024

MARISA Mid-Atlantic Regional Climate Summary map and title

Spring temperatures were warmer than normal for most of the Mid-Atlantic region. Explore future projected days with precipitation above two inches in the latest MARISA Seasonal Climate Impacts Summary and Outlook.

Highlights

Average temperatures for the 2024 spring season were 2–4 degrees F above normal for the majority of the region. This is slightly less warm compared to normal than the winter season, but is a few degrees warmer than the spring 2023 season.
Precipitation amounts varied across the region this spring, with some locations, particularly western Pennsylvania, experiencing greater than 150 percent of normal precipitation and a few areas receiving between 50 percent and 75 percent of normal spring precipitation.
The 2024 Atlantic hurricane season is forecasted with a high level of confidence to be an above-normal season with 17–25 named storms, 8–13 hurricanes, and 4–7 major hurricanes (defined as category 3, 4, or 5 with winds of at least 111 mph). Forecasters have a "higher-than-normal confidence" in their forecast for a very active season.
The Mid-Atlantic Region could see more than a 35 percent increase in the average annual number of days with precipitation above two inches by the middle of the century and a nearly 60 percent increase by the end of the century under a high emissions future climate scenario (SSP3-7.0).
