The Evaporative Demand Drought Index (EDDI) is an experimental tool that can serve as an indicator of both rapidly evolving "flash" droughts (developing over a few weeks) and sustained droughts (developing over months but lasting up to years).

The Climate Prediction Center has developed monthly and seasonal tools are based on the Constructed Analog on Soil Moisture (CAS). Note that both of these are only forecast tools. They may be used in making the official outlooks that go out to the public, but are not official forecasts in their own right.
The Climate Prediction Center has developed a soil moisture tool for the next 2 weeks based on the National Weather Service Global Forecast System (GFS) model. Note that these are only forecast tools. They may be used in making the official outlooks that go out to the public, but are not official forecasts in their own right. The GFS bias corrected ensemble forecasts (daily precipitation and temperature at 00Z & 12Z) for Week 1 and Week 2 are used to drive the soil moisture model.
Forecasts and current conditions for soil moisture (SM) and cumulative runoff. Forecast maps include precentiles at one-, two- and three-month leads
Available in spring and summer for the western U.S. Monthly streamflow maps compare precent of monthly average flow to their respective 1981-2010 average.
Data from the USDA for streamflow, forecasts, reservoir storage and other hydrologic information for the Western United States.
The Day 3 – 8 Fire Weather Outlooks are intended to delineate areas of the continental U.S. where pre-existing fuel conditions, combined with forecast weather conditions during the next 8 days, will result in a significant threat for the ignition and/or spread of wildfires. This product is designed for use in the NWS, as well as other federal, state, and local government agencies. Each outlook consists of a categorical forecast that graphically depicts fire weather risk areas across the...
The main objectives of the National Significant Wildland Fire Potential Outlooks are to improve information available to fire management decision makers. These assessments are designed to inform decision makers for proactive wildland fire management, thus better protecting lives and property, reducing firefighting costs and improving firefighting efficiency. The following maps represent the cumulative forecasts of the eleven Geographic Area Predictive Services Units and the National...
Climate outlooks describe the chances that conditions will be below-normal, near-normal, or above-normal for the outlook period indicated. The U.S. Seasonal Drought Outlook depicts large-scale trends based on subjectively derived probabilites guided by short- and long-range statistical and dynamical forecasts.
Where do these data come from?
Climate scientists base future climate outlooks on current patterns in the ocean and atmosphere. They examine projections...
NWS Graphical Forecast is an interactive map that displays current and forecasted meteorological products including: Temperature, Precipitation, Probability of Precipitation, Weather, Hazards, Dew Point, Relative Humidity, Wind Speed, Wind Gusts, Wind Direction, and Sky Cover.
