Will there be tornadoes in Oklahoma during Memorial Day weekend?

NWS Norman expects tornadoes in Oklahoma Saturday afternoon and evening. The weather service advised that strong, long track tornadoes are possible with any storm in any risk area.

As of Friday morning, Oklahoma City county, northern Cleveland County and eastern Canadian County were at a low risk for tornadoes Saturday.

Western Canadian County to western Custer County were at a medium risk for tornadoes that day along with areas in the northern part of the state, including parts of Enid.

Areas in the far west region of the state were at a very low risk for tornadoes, like Altus and Lawton, as well as the south central region, including Ardmore and parts of Durant.

Severe thunderstorms forecasted in Oklahoma Sunday

Large hail and damaging winds are forecasted in the southcentral region of the state Sunday afternoon and evening, according to NWS Norman.

Areas east of Stillwater, including Bartlesville and Tulsa county, are at a marginal risk for severe thunderstorms Sunday, according to NWS Tulsa.

Areas east of Tulsa to the Oklahoma-Arkansas border are at a slight risk for severe thunderstorms that day.

Level of categorical severe weather risks explained

The Storm Prediction Center, which is part of the National Weather Service, explained the risk levels associated with severe weather forecasts:

1. Marginal risk(dark green): An area of severe storms of either limited organization and longevity, or very low coverage and marginal intensity.

2. Slight risk (yellow): An area of organized severe storms, which is not widespread in coverage with varying levels of intensity.

3. Enhanced risk (orange): An area of greater (relative to slight risk) severe storm coverage with varying levels of intensity.

4. Moderate risk (red): An area where widespread severe weather with several tornadoes and/or numerous severe thunderstorms is likely, some of which should be intense. This risk is usually reserved for days with several supercells producing intense tornadoes and/or very large hail, or an intense squall line with widespread damaging winds.

5. High risk (magenta): An area where a severe weather outbreak is expected from either numerous intense and long-tracked tornadoes or a long-lived derecho-producing thunderstorm complex that produces hurricane-force wind gusts and widespread damage. This risk is reserved for when high confidence exists in widespread coverage of severe weather with embedded instances of extreme severe (i.e., violent tornadoes or very damaging convective wind events).
