Recent Significant Climate Anomalies and Events in the US

Explanation of Maps
The following maps were generated with observed and recorded data from weather stations across the continental United States compiled and displayed at the High Plains Regional Climate Center (HPRCC) located in Lincoln, NE. The data uses a baseline or “climate normal” based on the 30-year climate averages for locations for the years 1981-2010. The standard 30-year climate averages will be updated again for the time frame 1991-2020 at the conclusion of year 2020.

Explanation of Maps
NOAA’s Climate Prediction Center (CPC) issues seasonal climate forecast maps. These maps show the probabilities of unusually warmer/colder or wetter/drier seasons (relative to the 1981-2010 climate averages). Specifically, “A” indicates chances are leaning toward above average, “B” indicates chances are leaning toward below average, and “EC” indicates that there are equal chances for above average, below average, or average conditions. This information is generated from forecast models that use information on ocean, land, and atmospheric conditions such as sea surface temperatures (e.g., El Niño/La Niña conditions), presence/absence of sea ice or snow pack, and tropical weather patterns that can influence the location of the Jetstream and persistent areas of high/low pressure systems during a season. Note: These are seasonal forecasts not predictions with 100% certainty. For example, a single hurricane with heavy rain or a week-long cold air blast/heat wave can impact the outcome of these forecasts. Please see this 2-minute video on how to interpret these maps.
