Southeastern Oklahoma Weather by Season: Ice, Storms, Flooding and Heat

By Seth Willyard, Blue River Realty

Southeastern Oklahoma is the wettest and one of the mildest corners of the state. The Oklahoma Climatological Survey puts annual precipitation at about 56 inches in the far southeast, against about 17 inches in the western panhandle, and average snowfall at less than 2 inches a year. The weather that actually costs land owners money here is not cold or snow. It is ice on power lines and timber every so often in winter, fast-rising creeks in spring and fall, and humid heat from June into September.

This guide goes through the year the way an owner of a recreational tract meets it, using figures from the Oklahoma Climatological Survey, the Oklahoma Mesonet, the U.S. Forest Service and the National Weather Service. It is part of our Oklahoma recreational land guide.

The numbers in one table

Figures are for the far southeast of Oklahoma or for the Ouachita Mountains as a region, not for any one tract. Mountain weather varies with elevation and with which side of a ridge you are on.

The Climatological Survey adds a detail that matters for anyone planning a garden or food plot on a mountain tract: growing seasons in the Ouachita Mountains run three to four weeks shorter than in the surrounding lowlands, and freeze dates differ from nearby terrain by about two weeks in both spring and fall. A cold hollow and a south-facing bench on the same tract are not the same climate.

Winter: mild, with ice as the real risk

Most winters are easy. Soil rarely freezes deep or for long, snow is scarce, and the Climatological Survey notes that Southeastern Oklahoma has gone several years at a time between snow events. Winter is the season for clearing brush, walking property lines with the leaves off and working without ticks or snakes. Our fall and winter land guide covers that side.

The exception is freezing rain. Two entries from the Climatological Survey's weather timeline show what a bad one does:

• December 25 to 27, 2000. Ice and snow storms hit the state. With an earlier storm that month, at least 120,000 homes and businesses lost power, including 90 percent of residents in McIntosh, Latimer and Pittsburg counties. The Survey records at least 27 deaths and about $170 million in property damage, and 67 counties qualified for federal disaster relief.
• January 12 to 14, 2007. Frozen precipitation fell for nearly 72 hours. McAlester and Muskogee were hit hardest, with ice close to 4 inches thick, and about 125,000 customers were without power at the peak.

Deep cold is rarer still, but it happens. In February 2021 the state stayed below freezing for more than 200 hours and 96 of the Mesonet's 120 stations set all-time record lows, while two storms in the same stretch left 5 to 15 inches of snow statewide.

What that means on a tract:

• Rural power comes off long lines through timber. After a major ice storm, expect to be without it for days. A tract you visit on weekends should be able to sit unattended through an outage: drained water lines, no reliance on an electric heat source to protect plumbing.
• Ice brings down limbs and whole trees across roads and fences. Keep a chainsaw and fuel where you can reach them without driving in.
• Steep gravel in the mountains is not passable on ice. If your access climbs, plan to stay home or stay put.

Power, wells and plumbing choices are covered in utilities on rural land and in off-grid cabin living in Southeast Oklahoma.

Spring: storms, tornadoes and rising water

Spring is the main severe-weather season, though the Climatological Survey notes that severe storms can come at any time of year. Thunderstorms peak in late spring and early summer.

Tornadoes. Since 1950 Oklahoma has averaged 53 tornadoes a year. Three-quarters of them come in April, May and June, about 80 percent strike between noon and midnight, and the peak hours are 4 to 8 in the evening. The southeast sees fewer than the central part of the state. Choctaw County, on the Red River, recorded the fewest of any Oklahoma county between 1950 and 2024, with 27. Fewer is not none. The timeline lists an F5 tornado that killed 69 people in Antlers on April 12, 1945.

A tent, a camper or a small cabin is poor shelter in a severe storm. Know before you arrive where the nearest sturdy building is, and have a way to receive warnings that does not depend on a cell signal you may not have on the tract.

Rain and flooding. This is the hazard that most often catches land owners. The far southeast is the wettest part of Oklahoma, and it comes in bursts:

• The greatest annual total ever recorded at an official Oklahoma station was 84.47 inches at Kiamichi Tower, in the southeast, in 1957.
• In March 2008, Cloudy, Mt. Herman and Talihina each recorded more than 14 inches of rain in the month.
• In February 2018, the Broken Bow station recorded 17.65 inches, a state record for February.
• In September 2010, the remnants of Tropical Storm Hermine dropped more than 10 inches on eastern Oklahoma in under two days.

The Climatological Survey says major river floods are most frequent in spring and autumn and that flash flooding of creeks and small streams remains a serious threat. Mountain creeks rise in hours because steep, stony slopes shed water quickly.

The National Weather Service gives the numbers that should decide every low-water crossing:

• 6 inches of fast-moving water can knock over an adult.
• 12 inches of rushing water can carry away most cars.
• 2 feet can carry away SUVs and trucks.
• Over half of flood-related drownings happen when a vehicle is driven into flood water.

If the only way onto a tract crosses a creek without a bridge, there will be days you cannot get in and days you cannot get out. That is a reasonable trade for some buyers and a deal-breaker for others. Decide it before you buy, check the flood map with flood zones, surveys and title insurance, and weigh the two kinds of ground in mountain view vs creek bottom.

Rain is also what wears out roads. A driveway built without culverts and a crown will show it after the first wet spring; see first improvements on raw land.

Summer: heat and humidity

The southeast has fewer 100-degree days than western Oklahoma, about 15 a year against 30 to 40, and it is more humid. The humidity is what you feel. The Climatological Survey counts more than 40 days a year in the far southeast when the heat index reaches 105 degrees or higher, and about 85 days with highs of 90 or more.

For an owner that shapes the working day. Clearing, fencing and building are morning jobs from June to early September. Carry more water than you think you need, because most raw tracts have none on site. Shade and elevation both help: a ridge with a breeze is noticeably more comfortable than a still creek bottom on a July afternoon.

Summer is also peak season for ticks, and snakes turn nocturnal in the heat. Both are covered in snakes, ticks and field safety.

Late summer and fall: dry spells, then the best weather

Drought is a recurring part of Oklahoma's climate. The Climatological Survey notes that western Oklahoma is more drought-prone than the east, but the southeast is not immune, and dry spells can last from a few months to several years. A dry late summer drops ponds and creeks, hardens food plots and dries out the leaf litter and pine straw on the forest floor.

That is when burn bans appear. Before you light a brush pile or even a campfire on a fall weekend, check whether your county is under a ban; the rules are in burn bans, wildfire and prescribed burns.

Autumn is a second season for river flooding, especially when the remains of a Gulf tropical system move north. Between those events, October and November bring the weather people buy land here for: cool mornings, dry air and color in the hardwoods. Along the Red River the first fall freeze averages around November 10, and the mountains run about two weeks ahead of the lowlands.

How to check conditions on your own tract

• Oklahoma Mesonet. The Mesonet runs 120 automated weather stations, at least one in each of Oklahoma's 77 counties, reporting every five minutes. Find the station nearest your land and bookmark it. It gives current rain, temperature, wind and soil conditions, plus past monthly summaries.
• County climate summaries. The Oklahoma Climatological Survey publishes a climate document for each county, built from long-term National Weather Service cooperative stations and the Mesonet, with temperature and precipitation normals, freeze dates and extremes.
• National Weather Service. Forecasts and warnings for eastern Oklahoma come from the Tulsa office; the far southeast corner is covered by the Shreveport office. Watches and warnings are issued by county, so know which county your tract is in.

What the weather means when you are choosing land

• Access. Ask what the road is like after three inches of rain and after an ice storm, not on the dry day you visit. County roads vs private roads explains who is responsible for fixing it.
• Water on the ground. Walk the tract after rain if you can. Where water stands and where it runs tell you where not to build.
• Aspect and elevation. South and west slopes are hotter and drier. North slopes and hollows hold cold and frost.
• Trees near the building site. Ice and wind bring them down. Leave room.
• Insurance. Wind, hail, ice and flood are treated differently by insurers, and flood is usually a separate policy. Ask an insurance agent what is covered on vacant land and on any structure before you build.

Frequently asked questions

How much rain does Southeastern Oklahoma get?

About 56 inches a year in the far southeast, according to the Oklahoma Climatological Survey, which makes it the wettest part of the state. The U.S. Forest Service gives 48 to 56 inches across the Ouachita Mountains. Rain falls on roughly 115 days a year near the Arkansas border. The wettest year at any official Oklahoma station was 84.47 inches at Kiamichi Tower in 1957.

Does it snow in Southeastern Oklahoma?

Rarely. The Oklahoma Climatological Survey puts average annual snowfall at less than 2 inches in the extreme southeast and notes that the area has gone several years between snow events. Heavier snow does occur in unusual winters; two storms in February 2021 left 5 to 15 inches across the state. Freezing rain is the more damaging winter hazard here.

How bad are ice storms in Southeastern Oklahoma?

They are infrequent but can be severe. In December 2000, ice and snow cut power to at least 120,000 homes and businesses in Oklahoma, including 90 percent of residents in Latimer, Pittsburg and McIntosh counties. In January 2007, ice near 4 inches thick built up around McAlester and Muskogee. Owners of rural tracts should plan for multi-day power outages and blocked roads.

Is Southeastern Oklahoma in Tornado Alley?

It sees fewer tornadoes than central Oklahoma. Choctaw County, in the southeast, recorded the fewest of any Oklahoma county from 1950 to 2024, with 27. The risk is still real: an F5 tornado killed 69 people in Antlers in 1945. Statewide, three-quarters of tornadoes occur in April, May and June, most often between 4 and 8 in the evening.

How hot does it get in summer?

Highs reach 90 degrees or more on about 85 days a year in Southeastern Oklahoma, and 100 degrees on about 15 days a year in the east. Humidity is the bigger factor: the far southeast has more than 40 days a year when the heat index is 105 or higher. Plan heavy outdoor work for early morning from June through early September.

When is the best time of year to visit a tract?

For comfort, October, November and the spring months before the heat. For judging the land, visit at least twice: once in winter with the leaves off, when you can see the terrain, the views and the neighbors, and once after a heavy rain, when you can see where water runs and how the road holds up.
