Outlooks & Forecasts
1–5 Day
From April 23-28,, large portions of the contiguous U.S. are expecting at least moderate precipitation, with scattered heavy amounts over 2 inches. This includes a swath from northwestern Wyoming across southern Montana and most of the Dakotas, the Upper Mississippi Valley, through much of the Great Lakes and New England. Heavy amounts could be most widespread in the Red River (south) Valley, central Oklahoma, and from the central Plains into Iowa. In addition, most of the central and southern Great Plains should receive several tenths of an inch to near 2 inches, along with the Lower Mississippi Valley, southern and central Appalachians, and the interior Southeast. In the West, a few tenths to about 1.5 inches of precipitation are forecast for southern Oregon, northern and eastern California, the northern Great Basin, and the swath of higher elevations from central Utah through western Montana and adjacent Idaho. Meanwhile, little or no precipitation is forecast for most of the Four Corners Region, southern sections of the Great Basin and California, southern Texas, the immediate Gulf Coast, most of Florida, and southeastern Georgia. Below-normal temperatures are expected in the Southwest and California, with above-normal temperatures over most other portions of the Lower 48.
6–10 Day
The National Weather Service Climate Prediction Center’s 6–10 day outlook (valid April 29–May 3, 2025) favors wetter-than-normal conditions from the southeastern Rockies eastward through the Middle and Lower Mississippi Valley, and most of the eastern states outside eastern New England and southern Florida. Meanwhile, below-normal precipitation is most likely across the northern Plains, central and western Rockies, the Intermountain West, and California. Wet weather is slightly favored in the remaining dry areas in southeastern Alaska and Hawaii.
Warm weather should prevail across the contiguous United States outside the southern High Plains and adjacent Rockies. The greatest odds for warmth extend from California and the Great Basin through the northern Rockies and Intermountain West, as well as the lower Mississippi Valley and the eastern states. Above-normal temperatures are also significantly favored across Hawaii. Below-normal temperatures are expected to be limited to Alaska.
This weekly look ahead is modified from the U.S. Drought Monitor's National Drought Summary for April 22, 2025, written by Richard Tinker (NOAA's Climate Prediction Center) and Daniel Whitesel (National Drought Mitigation Center).

2-4 Week Hazard Outlook
Risk of Rapid Onset Drought
National Weather Service forecasters predict that rapid drought development (also known as "flash drought") may occur in the coming 2–4 weeks.
The Monthly Drought Outlook predicts whether drought will develop, remain, improve, or be removed in the next calendar month.
The Seasonal Drought Outlook predicts whether drought will develop, remain, improve, or be removed in the next 3 months or so.
This National Weather Service hazard outlook map shows the risk of rapid onset drought (flash drought) development during the next 2–4 weeks.
Forecasters use initial conditions, like existing dryness (e.g., soil moisture), temperature, and precipitation outlooks, to assess the risk of rapid drought development. Rapid onset drought risk areas (yellow) can give users, such as farmers making decisions about planting and supplemental irrigation, an early warning of the potential for hot and dry conditions.
The Climate Prediction Center issues its Monthly Drought Outlooks on the last day of the calendar month.
The Climate Prediction Center issues its Seasonal Drought Outlooks on the third Thursday of each calendar month. Sometimes, the map is adjusted on the last day of the month to maintain consistency with the Monthly Drought Outlook.
National Weather Service (NWS) forecasters issue rapid onset drought (ROD) risk areas on Thursdays, with the potential for updates on the following Mondays, from April 1–October 31.
The NWS Climate Prediction Center hazards outlook is issued between 2–5 p.m. ET, and this Drought.gov map updates at 7 p.m. ET.
Snow drought is a period of abnormally low snowpack for the time of year. Snowpack typically acts as a natural reservoir, providing water throughout the drier summer months. Lack of snowpack storage, or a shift in timing of snowmelt, can be a challenge for drought planning.
Learn MorePeriods of drought can lead to inadequate water supply, threatening the health, safety, and welfare of communities. Streamflow, groundwater, reservoir, and snowpack data are key to monitoring and forecasting water supply.
Learn MoreDrought can reduce the water availability and water quality necessary for productive farms, ranches, and grazing lands, resulting in significant negative direct and indirect economic impacts to the agricultural sector. Monitoring agricultural drought typically focuses on examining levels of precipitation, evaporative demand, soil moisture, and surface/groundwater quantity and quality.
Learn MoreDuring drought conditions, fuels for wildfire, such as grasses and trees, can dry out and become more flammable. Drought can also increase the probability of ignition and the rate at which fire spreads. Temperature, soil moisture, humidity, wind speed, and fuel availability (vegetation) are all factors that interact to influence the frequency of large wildfires.

Temperature, soil moisture, humidity, wind speed, and fuel availability (vegetation) are all factors that interact to influence the frequency of large wildfires.
Learn MoreAir temperature can have wide-ranging effects on natural processes. Warmer air temperatures increase evapotranspiration—which is the combination of evaporation from the soil and bodies of water and transpiration from plants—and lower soil moisture.
Learn MoreFlash drought is the rapid onset or intensification of drought. Unlike slow-evolving drought, which is caused by a decline in precipitation, flash drought occurs when low precipitation is accompanied by abnormally high temperatures, high winds, and/or changes in radiation. These sometimes-rapid changes can quickly raise evapotranspiration rates and remove available water from the landscape.

Learn MoreExtreme weather events can interact or cascade—where one disaster event triggers or changes the probability of another event. For example, drought conditions can increase the probability of large-scale wildfires, and droughts are often accompanied by extreme heat. By including drought in multi-hazard planning, a community can consolidate its resources and develop coordinated responses before a disaster.

Air temperature can have wide-ranging effects on natural processes. Warmer air temperatures increase evapotranspiration—which is the combination of evaporation from the soil and bodies of water and transpiration from plants—and lower soil moisture.
Learn MoreFlash drought is the rapid onset or intensification of drought. Unlike slow-evolving drought, which is caused by a decline in precipitation, flash drought occurs when low precipitation is accompanied by abnormally high temperatures, high winds, and/or changes in radiation. These sometimes-rapid changes can quickly raise evapotranspiration rates and remove available water from the landscape.

Learn MoreSnow drought is a period of abnormally low snowpack for the time of year. Snowpack typically acts as a natural reservoir, providing water throughout the drier summer months. Lack of snowpack storage, or a shift in timing of snowmelt, can be a challenge for drought planning.
Learn MoreDrought can reduce the water availability and water quality necessary for productive farms, ranches, and grazing lands, resulting in significant negative direct and indirect economic impacts to the agricultural sector. Monitoring agricultural drought typically focuses on examining levels of precipitation, evaporative demand, soil moisture, and surface/groundwater quantity and quality.

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).
