National Current Conditions

January 13, 2021 - January 19, 2021

While drought persisted across the West in 2020, the Southeast was mostly wet. However, abnormal dryness now appears in Alabama, Florida, Georgia, South Carolina, Louisiana, and Mississippi. La Niña may turn that dryness into drought. According to NOAA's Climate Prediction Center, La Niña is expected to continue through the winter and early spring. This week’s U.S. Drought Monitor change map shows mostly small degradations scattered around the U.S. The exception is a large area of dryness developing across Kentucky and Tennessee, though some of this may improve with incoming precipitation. Extreme (D3) to Exceptional (D4) Drought continues across much of the Plains, Rockies, and Southwest. As of January 19, 2021, 37.64% of the U.S. was in drought.

U.S. Drought Monitor

The U.S. Drought Monitor (USDM) is updated each Thursday to show the location and intensity of drought across the country using a five-category system, from Abnormally Dry (D0) conditions to Exceptional Drought (D4).

The USDM is a joint effort of the National Drought Mitigation Center, USDA, and NOAA. Learn more.

The USDM Change Map shows where drought has improved, remained the same, or worsened since the previous week's Drought Monitor. Learn more.

Precipitation Conditions

The current precipitation conditions show the precipitation accumulation for the last 7 days using the gridMET and NLDAS precipitation datasets, which are delayed from the current day by 2 to 3 days to allow for data collection and quality control. The last 30- and 60-day percentages of normal precipitation are also available, which show the difference of the last 30 or 60 days from the usual conditions for the same time period averaged since 1980. Learn more.

Drought Indicator Blends

These experimental drought blends integrate several key drought monitoring products and indices into a single short-term or long-term product, based on the methodology developed at the NOAA Climate Prediction Center. The blends are created using the Climate Engine tool, and apply the CPC weighting ratios to the high-resolution gridMET gridded research dataset. The data is updated daily, with a delay of 2 to 3 days to allow for data collection and quality control. The short-term blend combines PDSI, Z-Index, 1-month SPI, and 3-month SPI to estimate the overall short-term drought. This product is an example of current NIDIS-funded researchLearn more.

Palmer Drought Severity Index (PDSI)

This new experimental implementation of the Palmer Drought Severity Index (PDSI) updates every 5 days using the high-resolution gridMET gridded research dataset and USDA STATSGO soils data. The PDSI is a standardized index based on a simplified soil water balance and estimates relative soil moisture conditions. The magnitude of PDSI indicates the severity of the departure from normal conditions. A PDSI value >4 represents very wet conditions, while a PDSI <-4 represents an extreme drought. 

This PDSI uses a new methodology for sub-monthly PDSI. Learn more.

Evaporative Demand Drought Index (EDDI)

The Evaporative Demand Drought Index (EDDI) is an experimental drought monitoring tool that can serve as an indicator of both rapidly evolving "flash" droughts and sustained droughts. It examines how anomalous the atmospheric evaporative demand (E0; also known as "the thirst of the atmosphere") is for a given location and across a time period of interest. EDDI can offer early warning of agricultural drought, hydrologic drought, and fire-weather risk. Learn more.
