Weekly Look Ahead

June 27, 2024 (Updated Every Thursday)

1–5 Day

During the next five days (June 27–July 1), a couple of storm systems and trailing frontal boundaries are forecast to bring periods of rainfall to portions of the eastern U.S. These storm systems are likely to usher in some cooler-than-normal air behind them, particularly across the northern tier of the lower 48 states. 

Temperatures are expected to remain predominantly warmer than normal across the southern tier of the U.S., with excessive heat also possible across the Gulf Coast states.

6–10 Day

The Climate Prediction Center’s 6–10 day outlook (valid July 2–6), favors enhanced chances of above-average temperatures across the southern two-thirds of the lower 48 states and near- to below-normal temperatures across the northern tier states. Near- to below-normal temperatures are also favored in the Desert Southwest, due to the increased potential for above-normal precipitation. Below-normal precipitation is favored across parts of California and Nevada, and across the southeastern U.S. Increased above-normal precipitation chances are favored elsewhere across the lower 48 states, with the highest chances across portions of the Southwest and Midwest.

 

This weekly look ahead is modified from the U.S. Drought Monitor's National Drought Summary for June 25, 2024, written by Adam Hartman (NOAA's Climate Prediction Center) and Rocky Bilotta (NOAA's National Centers for Environmental Information).

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).
