Weekly Look Ahead

August 21, 2025 (Updated Every Thursday)

1–5 Day

From August 21–26, the heaviest precipitation is forecast along the East Coast, especially from North Carolina through the Mid-Atlantic and into southern New England, where amounts may exceed 5 inches, likely tied to a coastal storm system. Pockets of heavier rain are also expected in parts of the central Rockies, High Plains, and southern Texas, with localized totals between 2 and 4 inches. Much of the Midwest, Southeast, and Southwest are forecast to receive lighter but widespread rainfall, generally between 0.5 and 2 inches. By contrast, the Pacific Northwest and much of California show little to no precipitation expected. Overall, the forecast highlights a wet period for the East Coast and scattered parts of the interior U.S., while the West Coast remains mostly dry.

6–10 Day

The National Weather Service Climate Prediction Center’s 6–10 day outlook (valid August  26–30, 2025) shows much of the Central and Eastern U.S. is expected to be cooler than normal, with the greatest chance for well-below-average temperatures across the Midwest and Ohio Valley. In contrast, warmer-than-normal conditions are favored along the West Coast, especially in the Pacific Northwest and northern California, as well as in Florida, parts of Alaska, and Hawaii. Rainfall patterns show a split across the country: wetter-than-normal conditions are likely in the central and southern Rockies, the Southwest, and the central Plains, along with parts of Alaska. Drier-than-normal conditions are forecast for the Great Lakes, Ohio Valley, and portions of the interior Northeast. Overall, the late-August outlook points to a cool and damp stretch for much of the central U.S., warmer weather along the West Coast and in the far South, and a drier setup in the Great Lakes and Ohio Valley.

Featured Outlooks & Forecasts

Predicting drought depends on the ability to forecast precipitation and temperature within the context of complex climate interactions. Many different datasets and maps are available that predict how precipitation and temperature may change in the future.

Challenges with Predicting Drought

Pressure Systems

High pressure systems, which hinder cloud formation and lead to low relative humidity and precipitation, can cause drought. When large-scale anomalies in atmospheric circulation patterns last for months or seasons, prolonged drought occurs (NDMC).

Temperate Zone Forecast Reliability

In temperate regions (above 30 north latitude), long-range forecasts have limited reliability. Due to differences in observed conditions and statistical models, reliable forecasts for temperate regions may not be attainable for a season or more in advance (NDMC).

Interconnected Variables

Anomalies in precipitation and temperature may last from several months to several decades, and how long they last can depend on air–sea interactions, soil moisture, land surface processes, topography, and weather systems at the global scale (NDMC).

ENSO and Global Weather Patterns

Teleconnections, such as ENSO and La Niña events, are atmospheric interactions between widely separated regions. Understanding these teleconnections can help in forecasting droughts, floods, tropical storms, and hurricanes (NDMC).
