Payne County has 59 tornadoes in NOAA’s Storm Prediction Center (SPC) record from 1950 through 2025. Stillwater is its county seat. Five were rated F3/EF3 or stronger, and one reached F4. Three people died in tornadoes that touched the county.

Two tornadoes account for all three deaths

May 3, 1999. An F4 on a 35-mile path through Logan, Noble and Payne counties killed 2 people and injured 26. It came on the same day as the F5 that crossed Cleveland County and Oklahoma County. The record lists the two as separate tornadoes. It is the strongest and the deadliest tornado in the county’s record.

May 15, 1990. An F3 with a 7-mile path, recorded only in Payne County, killed 1 person and injured 12.

Ratings and casualty figures cover the full tornado path, including stretches outside Payne County.

Mostly weak tornadoes, and no strong one since 2016

Of the 59 tornadoes, 41 were rated F0/EF0 or F1/EF1, and one has no known rating. From 2016 through 2025 the county had 9 tornadoes, none of them rated EF3 or stronger.

Weak tornadoes were also undercounted in the early decades. That makes strong-tornado counts the fairer way to compare one period with another.

Clay that sits below the surface

About 32% of the county’s mapped land has soils rated high for shrink-swell: clay that swells when wet and shrinks as it dries. None of it falls in the very high class. The top layer of soil is much milder: only about 0.2% of mapped land is rated high there. The largest high-rated area is a Grainola-Lucien complex on 5–12% slopes, at 21,975 acres. It sits right on the line between moderate and high. These are county map figures rather than a reading of one lot. For what this kind of soil means for a house, see foundation repair in Oklahoma.

Getting a shelter priced for your home

A quote request goes to a local installer. The installer can look at your house and yard and tell you whether a garage-floor, in-ground or above-ground shelter fits. Ask for a written, itemized price that names:

  • the shelter
  • whether a permit is needed and who will pull it
  • any permit fee

That way you can compare bids line by line. Published guide ranges are on storm shelter costs in Oklahoma. Shelter options statewide are on storm shelters in Oklahoma.
