Comment: Per several declines of Draft:September 14 tornado outbreak, comments here and at Luna.t5's talk page. This topic is not notable so time to move on. There are plenty of other activities you can do to help so suggest checking out WP:WikiProject Weather. S0091 (talk) 16:12, 19 September 2025 (UTC)
- Comment: This has been declined several times before; the templates were removed. I personally don't think this is notable as I don't see WP:SUSTAINED coverage of the event but I won't review it. EF5 16:02, 19 September 2025 (UTC)

The September 13-15 tornado outbreak was caused by a powerful extratropical cyclone that produced widespread, linear tornado damage across North Dakota, Kansas, Iowa, and South Dakota with Texas receiving hurricane-force wind gusts. It lasted for 8 hours, and produced moderate damaging tornadoes and small scale cyclonic winds. The cyclone's winds were way below normal for a extratropical cyclone. The outbreak was historic, with more tornadoes recorded than North Dakota had seen for 3 decades combined[1]

A area of low pressure formed over the Central Plains ahead of a warm front that was moving toward North Dakota, moving up across the North Dakota border toward Canada, causing squalls on Lake Erie gusting to 35 kts (40 mph).
Storm development
[edit]At 5:00 PM UTC, thunderstorms started developing in south central North Dakota due to extremely high low-level shear, seasonal dew points of 64-70 °F (17.7-21.1 °C), and jet stream influence.[2]
Tornado watch issuance
[edit]At 6:10 PM UTC, a tornado watch was issued because the atmosphere was becoming extremely favorable for strong, long-tracked tornadoes.[2]
First warnings
[edit]Next, at 7:22 PM and 7:25 PM UTC respectively, two PDS tornado warnings were issued, each causing damage to multiple elementary schools in suburban Bismarck.[3]
Later on, over 20 tornado warnings were issued as the outbreak magnified in intensity with storms merging into each other and influencing as they were less than 1 mi (0.6 km) apart.[3]
Results

Here, a concentrated corridor of enhanced low-level vorticity accompanying a northward-moving MCV will continue to support embedded low-level mesocyclones with a risk of a couple tornadoes. In the near-term, the tornado risk should generally be maximized in the path of the MCV. With time, additional development will be possible along a warm front draped across parts of south-central and southeastern ND -- aided by a strengthening low-level jet and diurnal heating of a moist boundary layer (lower 70s dewpoints). Any sustained storms in the vicinity of the warm front may become superceullular and pose a risk of a couple tornadoes, given the favorable/strengthening low-level shear and destabilizing boundary layer."
