2023 Weather in Review: New River Gorge National Park and Preserve

NPS photo

In order to better understand ecosystem health in national parks, the Eastern Rivers and Mountains Network measures ecosystem "vital signs" in select national parks in West Virginia, Pennsylvania, New Jersey, and New York. One of those vital signs is weather and climate. Below is a summary of 2023 weather conditions at New River Gorge National Park and Preserve.

This brief provides county-scale weather data averaged from all of the counties surrounding the park, including data from 1895–2023 (i.e., period of record). These counties include Fayette, Raleigh, and Summers counties, West Virginia. Data and analyses herein are courtesy of the National Oceanic and Atmospheric Administration's (NOAA) Climate at a Glance Program.

Weather vs. Climate

First of all, what is the difference between weather and climate? Weather consists of the short-term (minutes to months) changes in the atmosphere. Weather is what is happening outside at this very moment, be it rain, snow, or just a warm sunny day. Climate is what you expect to see based on long-term patterns of over 30 years or more. An easy way to remember the difference is that climate is what you might expect, like a hot summer, and weather is what you get, like a warm rainy day.

The following information includes a discussion of 2023 weather placed in the context of long-term climate (i.e., how did 2023 compare to a "normal" year?).

2023 Summary

In all, 2023 was much warmer than average for Fayette, Raleigh, and Summers counties, West Virginia. In contrast, total annual precipitation was just below normal. The year ended as the 7^th warmest and 44^th driest on record (since 1895). Data indicate that over the long term, annual average temperature and annual total precipitation have both increased (+0.05°F per decade and +0.06 inches per decade, respectively).

Temperature

In total, 2023 was the 7^th warmest year recorded at the park. Seasonally, the fall and winter were particularly warm (Figure 1). Eight months had warmer than normal temperatures, and January and February were more than 7.5°F above long-term averages (Table 1).

Precipitation

It was a slighly dry year for counties surrounding the park, with most seasons being near or below normal for precipitation. The year ranked as the 44^th driest on record (Figure 2). In total, 41.64 inches of precipitation fell, almost 2.75 inches less than the long-term average (Table 2).

Temperature and Precipitation Trends
(1895-2023)

Data for Fayette, Raleigh, and Summers counties, WV indicate that annual average temperature has increased approximately 0.05°F per decade and annual total precipitation has increased approximately 0.06 inches per decade since 1895 (Figure 3).

National Park Service scientists have forecast future changes in climate too. Models estimate that by 2100, annual average temperature at the park will increase by 2.9–8.6°F (from a best-case to worst-case scenario, respectively). Annual total precipitation is expected to increase by 6–11% (see Gonzalez et al., 2018 for details).

Climate Change

Today's rapid climate change challenges national parks in ways we've never seen before. Wildlife migrations are altered, increasingly destructive storms threaten cultural resources and park facilities, habitat is disrupted—the list goes on.
