Plains and Upper Midwest Brace for Long-Tracked Tornadoes and All Severe Hazards Monday May 18 Including Lincoln, Oklahoma City, Minneapolis and Chicago in Higher-End Outbreak Scenario
LINCOLN, Nebraska – A higher-end severe weather outbreak capable of producing strong, long-tracked tornadoes is shaping up across the Plains and Upper Midwest for Monday, May 18. Forecast data is painting a particularly alarming picture for communities from Oklahoma City north through Lincoln and Minneapolis, with all significant severe weather hazards on the table.
Why Monday May 18 Looks Especially Dangerous
What makes Monday, May 18 stand out from a typical severe weather day is the combination of ingredients coming together simultaneously across a wide corridor. Forecast models are depicting a very favorable setup for strong, long-tracked tornadoes, meaning tornadoes that stay on the ground for extended distances rather than brief touchdowns. This is considered a higher-end scenario compared to most other guidance currently available, but forecasters are treating it as a realistic depiction of what Monday could bring.
What a Particularly Dangerous Situation Tornado Threat Means
Forecast data for Monday, May 18 is flagging what meteorologists call a Particularly Dangerous Situation tornado threat, or PDS TOR, for portions of the Plains and Upper Midwest. A PDS TOR designation is reserved for the most extreme tornado setups, where violent, long-tracked tornadoes capable of significant destruction are considered likely rather than just possible. This is not issued lightly and represents one of the most serious tornado threat classifications forecasters use.
Cities Facing the Greatest Danger Monday
The following cities are within or near the highest-risk corridor for Monday, May 18:
- Lincoln, Nebraska sits inside one of the most concerning zones on the forecast maps for Monday and faces a real threat of long-tracked tornadoes, very large hail and damaging winds.
- Oklahoma City, Oklahoma is also highlighted within the severe weather corridor and should prepare for all hazards including tornadoes on Monday, May 18.
- Minneapolis, Minnesota falls within the broader severe weather threat area for Monday and could see significant storms push through during the afternoon and evening hours.

- Louisville, Kentucky and Denver, Colorado are also visible within the broader setup area and should monitor conditions closely heading into Monday.
All Severe Hazards Expected
Monday, May 18 is not a single-threat event. Forecasters are highlighting all significant severe weather hazards for the Plains and Upper Midwest:
- Strong, long-tracked tornadoes capable of staying on the ground for extended distances represent the most dangerous threat for Monday, May 18 across the Plains corridor.
