Current Map Historical Timeseries
The U.S. Drought Monitor depicts the location and intensity of drought across the country. The map uses 5 classifications: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4).

The U.S. Drought Monitor depicts the location and intensity of drought across the country. This historical timeseries shows the progression of drought & dryness across Kansas, Texas, and Oklahoma from 2000 to the present, as a percent of total land area.
Key Takeaway: Drought in the Texas Hill Country has gone through episodes of intensification and improvement. Notably,Kendall County Texas, has been in Extreme Drought (D3) or worse for over 110 weeks. Flash drought (rapid drought intensification) developed over northern Oklahoma and central Kansas in April. For example, Ford County, Kansas, began the month of April with no drought and ended the month with 100% of the county in Severe Drought (D2).
The first two weeks of May were very wet for most of Oklahoma, withmore than 5 inches of rain in eastern Oklahoma and more than2 inches in western Oklahoma. Severe Drought (D2) remains in northwest Oklahoma.

Adrought indexcombines multiple drought indicators (e.g., precipitation, temperature, soil moisture) to depict drought conditions. For some products, like the U.S. Drought Monitor, authors combine their analysis of drought indicators with input from local observers. Other drought indices, like the Standardized Precipitation Index (SPI), use an objective calculation to describe the severity, location, timing, and/or duration of drought.
Periods of drought can lead to inadequatewater supply, threatening the health, safety, and welfare of communities. Streamflow, groundwater, reservoir, and snowpack data are key to monitoring and forecasting water supply.
Drought 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. Monitoringagricultural drought typically focuses on examining levels of precipitation, evaporative demand, soil moisture, and surface/groundwater quantity and quality.

Current Conditions for the Southern Plains
- A dry February through April resulted inflash droughtdevelopment (i.e., rapid drought intensification) in central and western Kansas and western Oklahoma.
- Dodge City had 0.02 inches of rain in April, which ties 1909 as the driest April on record. With a combined 2-month total rainfall of only 0.27 inches, Dodge City, Kansas, had its driest March–April on record.
- South Texas Heatwave: May 9 was one of the hottest days ever recorded in the Rio Grande Valley. New May maximum temperature records were set at:
- McAllen, Texas, 111°F. The previous record was 110°F on May 4, 1999. McAllen tied an all-time station record from June 22, 2017.
- Harlingen, Texas, 107°F. The previous record was 105°F on May 12, 1974.
- Brownsville, Texas, 104°F. The previous record was 102°F on May 22, 1916; May 11, 1974; and May 5, 1999.
- Del Rio, Texas, 109°F. Tied the previous record set on May 24, 2000.
2-Month U.S. Drought Monitor Change Map (Since March 19, 2024)
Key Takeaway:Central Kansas experienced a four-category degradation in drought conditions over the 8 weeks from March 19 to May 14. Parts of northern Oklahoma also saw rapid intensification of drought over the same period, with a two-category degradation.
30-Day Percent of Normal Precipitation for the Southern Plains
Key Takeaway: Most of Texas, Oklahoma, and Kansas usually receive between 10%–15% of their annual precipitation in May. (The primary exception is the Upper Rio Grande region of far west Texas, which is usually very dry in the months before the onset of the Southwest Monsoon). For places like Dodge City, Kansas, this is usually between 3 and 3.5 inches of precipitation. Dodge City received only 0.84 inches of rainfall over the last 30 days and has not yet exceeded 3 inches of rainfall for the year to date.
May-to-Date Departure from Normal Maximum Temperature
Key Takeaway:Early May has been exceptionally hot across southern Texas, setting new temperature records. Drought has developed or intensified in that part of the region.
Southern Plains Drought Impacts
- Lower Rio Grande water shortages:
- Drought puts a strain on the U.S.-Mexico water treaty.
- Cities along the lower Rio Grande enacted drought declarations and water restrictions:
- A dry February through April resulted in subsoil drying and led to poor wheat growth in central and western Kansas and western Oklahoma.
- Thewinter wheat crop inKansas has been rated very poor for the fourth straight week, according to the U.S. Department of Agriculture.
- Inseveral central Kansas counties, the last decent precipitation for the wheat came on February 5.
- A dry spell of 80 to 105 days affected wheat in northwest Oklahoma. For most of northwest Oklahoma, the dry spell lasted from February 5 to May 12.

28-Day Average Streamflow Conditions (Valid May 13, 2024)
Key Takeaway:Meteorological drought over northern Oklahoma and central Kansas since February has curtailed streamflow and led to hydrologic drought conditions, with the most severe conditions in south-central Kansas. South Texas, especially the Hill Country, is seeing the impacts of persistent (100+ weeks) drought, including much below average streamflow.
Texas Reservoir Levels
Key Takeaway: Reservoir levels in eastern Texas improved over the past two months, while reservoir levels in central and southern Texas remained low. A few notable reservoirs in drought status are:
- Falcon Reservoir, Rio Grande: 9.4% full
- Amistad Reservoir, Rio Grande: 27.9 % full
- Medina Lake, Medina River: 2.7% full
Oklahoma Reservoir Levels
Key Takeaway: Most reservoirs in northeastern Oklahoma are generally 90+% full, while most reservoirs in the southwestern part of the state are less than 80% full.
Outlooks and Potential Impacts for the Southern Plains
- The summer months (June-July-August) are usually the wettest time of the year for Southern Plains states, especially for the western part of the region that can usually pick up some rainfall from the Southwest Monsoon.
- The latest monthly and seasonal climate outlooks show:
- A hot and dry summer is ahead for the western parts of the Southern Plains that usually expect monsoonal rainfall.
- A warm and wet summer for the eastern part of the region, including the Gulf Coast.
- El Niño is on the way out. La Niña is on deck.
- El Niño weakened significantly over the last few months, which is typical in spring months.
- Early summer will be governed by a neutral pattern (neither El Niño nor La Niña), which means that this climate pattern is not driving weather patterns in early summer.
- A La Niña pattern is likely to develop by mid- to late-summer and will last through winter. La Niña usually, but not always, correlates with a wetter and cooler summer for southern Texas, but a drier summer for the rest of the Southern Plains (with no strong influence on temperatures).
- Looking further ahead, La Niña usually, but not always, correlates with a drier winter for the southern U.S.
June 2024 Temperature Outlook
Key Takeaway:Odds favor above-normal temperatures for all of the Southern Plains DEWS region for June, with the highest odds for Texas.
Seasonal (3-Month) Temperature Outlook: Summer (June–August) 2024
Key Takeaway: A warmer-than-normal summer is likely for the Southern Plains DEWS Region. Highest odds (60%-70% chance) of a warmer-than-normal summer are over the Upper Rio Grande region of western Texas.
June 2024 Precipitation Outlook
Key Takeaway: June in the Southern Plains can possibly expect (33%–50% chance) below normal precipitation for western and central Texas, but odds slightly favor (33%-50% chance) above normal precipitation for eastern Kansas and northeast Oklahoma.
Seasonal (3-Month) Precipitation Outlook: Summer (July–August) 2024
Key Takeaway: The latest precipitation outlook shows lower-than-normal precipitation from the Southwest Monsoon this summer. This extends into far western Kansas, Texas, and the Oklahoma panhandle (33%–40% chance). The eastern U.S., including the Gulf Coast region of Texas, can likely (33%-40% chance) expect a wetter-than-normal summer.
