Exceptional drought, the most severe category on the U.S. Drought Monitor, now covers 16.59% of Oklahoma after expanding by 3.46 percentage points in a single week. New areas of exceptional drought appeared in Bryan, Atoka, Stephens and Jefferson counties in southern Oklahoma, according to the Oklahoma Farm Report's analysis of the map released Sept. 17. Every part of the state is now in moderate drought or worse, and none of Oklahoma is drought-free.

The practical effect is showing up on farms. Oklahoma winter wheat seeding stood at 3% complete for the week ending Sept. 13, half the five-year average of 7%, with a lack of soil moisture cited as the main reason, according to a DTN analysis of crop progress data. DTN ag meteorologist emeritus Bryce Anderson wrote that the extent and severity of drought in Oklahoma are the greatest since the bone-dry year of 2012.

That delay matters well beyond grain. Many Oklahoma cattle operations depend on grazing young wheat through fall and winter, and a late or thin stand means ranchers may need to buy more hay or cut herd numbers.

How Oklahoma Went from Wet to Parched in Weeks

Nature World News reported in August that the share of Oklahoma in some form of dryness had jumped from about 65% to nearly 96% in a single week. Since then, the worst category has spread into southern counties, and drought now blankets the entire state.

The change from a year ago is stark. In September 2025, only about 25% of Oklahoma had any dryness, with none in severe drought, according to DTN. By Sept. 8, 2026, almost 89% of the state was in severe, extreme, or exceptional drought.

The weather behind it has been relentless. Much of central and western Oklahoma has logged more than 50 days above 100 degrees Fahrenheit this year, according to Oklahoma Mesonet data cited by DTN, and the state's southwestern corner has recorded 70. Large parts of central, southern and southeastern Oklahoma went more than 50 consecutive days with less than a quarter inch of rain, and central and western Oklahoma received no more than about 4 inches in June through August, mostly 25% to 75% of normal.

Why Flash Drought Feeds Itself

Most droughts develop over months or years. A flash drought develops in weeks, driven by little rain combined with intense heat, strong sunshine, and wind that pull moisture from soil and plants. Drought.gov reported that as of Sept. 15, flash drought was continuing to worsen across the southern Plains and the lower Mississippi River Basin.

Heat and drought reinforce each other. When soil is moist, part of the sun's energy goes into evaporating water, which keeps the ground cooler. When soil dries out, more of that energy heats the ground and the air above it. The persistent September heat dome over the south-central United States amplified that cycle.

The U.S. Drought Monitor's commentary for the week of Sept. 8, quoted by DTN, described temperatures 5 to 15 degrees above normal from western and northern Texas through most of Oklahoma, Arkansas, northern Mississippi and Tennessee, with dropping soil moisture and streamflow "leading to widespread agricultural drought impacts."

Parched Ground Changes What Rain Does

Rain is not always the simple fix it seems. Just south of the Red River, storms on Sept. 20 prompted a flash flood warning after emergency management reported impassable roads and potential water rescues in Denison, Texas, according to the NWS Fort Worth warning text. Very dry, hardened soil can absorb heavy rain slowly at first, so intense downpours may run off into streets and creeks instead of soaking in.

That pattern is a reminder for Oklahoma. A single heavy storm could flood low spots while doing little to rebuild deep soil moisture, stock ponds, or wheat seedbeds. Slower, steadier rain over several days does more for drought recovery than a brief cloudburst.

There is some hope in the forecast. DTN said forecast maps through the end of September suggest some beneficial moderate to heavy rain for the southern Plains, including Oklahoma, and the Climate Prediction Center's six-to-10-day outlook leaned toward above-normal rain chances for western Oklahoma, according to the Oklahoma Farm Report. Those outlooks are probabilities, not guarantees, and even a wet stretch would need weeks to reverse a drought this deep.

Who Is Paying the Price and What Comes Next

Ranchers face the most immediate strain. Pastures have stopped growing, stock ponds are shrinking, and delayed wheat pasture pushes feed costs higher. Farmers waiting to plant winter wheat face a narrowing window. Rural households on private wells should watch for dropping water levels, and communities that rely on small reservoirs may see voluntary or mandatory conservation measures.

Wildfire risk is also rising. Cured grasses and low fuel moisture help fires spread quickly. Residents should avoid outdoor burning, follow county burn bans, keep vehicles off dry grass and report smoke promptly.

Help is available. USDA Farm Service Agency drought programs, including the Livestock Forage Disaster Program, use Drought Monitor categories to help determine eligibility, so producers should contact their county FSA office and document losses now. Oklahoma State University Extension also offers drought management resources.

The next map will be released Thursday, Sept. 24, reflecting conditions through Sept. 22, and readers can follow the Oklahoma Drought Monitor map as it updates. The key question is whether late-September rain arrives as forecast and soaks in rather than running off. Until then, Oklahoma remains in its most severe drought in more than a decade.

What Readers Want to Know

How bad is Oklahoma's drought right now?

As of the Drought Monitor map released Sept. 17, exceptional drought covered 16.59% of the state, and 100% of Oklahoma was in moderate drought or worse. DTN called it the most severe drought in Oklahoma since 2012.

What is a flash drought?

A drought that develops over weeks rather than months, driven by little rain combined with heat, sunshine, and wind that rapidly dry out soil and plants.

Which counties were newly added to exceptional drought?

Bryan, Atoka, Stephens, and Jefferson counties in southern Oklahoma, according to the Oklahoma Farm Report.

How is the drought affecting agriculture?

Winter wheat seeding was 3% complete for the week ending Sept. 13, half the five-year average, which delays the wheat pasture many cattle operations rely on.

Will rain end the drought?

Forecasts suggest some rain in late September, but a single storm on hardened soil may run off rather than soak in. Recovery from drought this deep usually takes weeks of steady rainfall.

Where can farmers and ranchers get help?

County USDA Farm Service Agency offices administer drought assistance programs, and Oklahoma State University Extension offers management guidance.

When is the next drought update?

The U.S. Drought Monitor releases a new map every Thursday. The next map comes out Sept. 24.
