Weekly Look Ahead

September 17, 2026 (Updated Every Thursday)

1–5 Day

Through next Tuesday, above-normal rainfall is forecast in South Florida, as well as a large area from southern Wisconsin and Minnesota into eastern Iowa and northern Illinois. Rainfall will continue to the east through central Michigan, the southern Great Lakes, Pennsylvania, New York, and much of central and southern New England. Rain is also forecast in the Appalachian Mountains, the western Great Plains, and the Four Corners states. 

Unfortunately, most of Texas, Oklahoma, Arkansas, Louisiana, Mississippi, and Alabama are forecast to receive little rainfall. Dry conditions are also forecast in California, Nevada, and Washington. Much-above-normal temperatures are forecast to continue this week in the Central and Southern U.S.

6–10 Day

The National Weather Service Climate Prediction Center's 6–10 day outlook (valid September 22–26, 2026) favors above-normal temperatures over nearly all of the Lower 48, plus Hawaii. The highest chances of above-normal temperatures are from the South into the Southeast, the far North, and Hawaii.

The Eastern Seaboard and the Southwest U.S. are both likely to receive above-normal rainfall next week. Below-normal rainfall is favored over the Central U.S. into the Upper Midwest. Odds favor above-normal rainfall in Hawaii and Alaska.

 

This weekly look ahead is modified from the U.S. Drought Monitor's National Drought Summary for September 15, 2026, written by David Mocko (National Aeronautics and Space Administration) and Lindsay Johnson (National Drought Mitigation Center).

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).
