Outlooks & Forecasts
1–7 Day
Like the last 7 days, a southerly flow of Gulf of Mexico moisture will feed showers and storms that develop from the Rockies to the Mississippi River during the next 7 days. An inch or more of rain is forecast from the Southern Plains to northern Rockies, with locally 4 inches or more from the Texas panhandle to southern Kansas, and locally 2 inches or more in parts of Colorado to Montana. A fourth of an inch or more can be expected from California’s Sierra Nevada to the Great Basin, across the Northern Plains to Mississippi Valley, in the Tennessee Valley, across the Gulf of Mexico coast, and along the Appalachians to Northeast. New England may see over an inch of rain, while much of the Florida peninsula will be inundated with another 2+ inches of rain. Little to no precipitation is predicted for the eastern Great Lakes to Ohio Valley, the interior Southeast, and southern and western portions of the West.
6–10 Day
For June 6–14, a warmer-than-normal pattern is likely for the Pacific Northwest to western Great Lakes, the northern half of Alaska, and the Alaska panhandle, with cooler-than-normal temperatures across southern portions of the West, the Southern Plains, and from the Appalachians to New England.
Odds favor wetter-than-normal conditions across the West, Southern Plains, western portions of the Central to Northern Plains, and the southwest half of Alaska, with drier-than-normal conditions across the Great Lakes, Upper Mississippi Valley, Ohio Valley, and northeast Alaska.
This weekly look ahead is modified from the U.S. Drought Monitor's National Drought Summary for May 30, 2023, written by Richard Heim and Rocky Bilotta (NOAA's National Centers for Environmental Information).

The Evaporative Demand Drought Index (EDDI) is a drought monitoring tool that shows the anomaly in daily evaporative demand (the "thirst of the atmosphere") over a given period time. Unusually high evaporative demand can lead to moisture stress on the land surface, and ultimately to drought—even when precipitation has been near normal.
This experimental subseasonal EDDI forecast shows projected evaporative demand for the next 14 days from the CFS-gridMET dataset at 4-km gridded resolution.

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).
