EF0 tornado in Dyer County, Tennessee

A weak, short-lived EF0 tornado touched down on the southeast side of Dyersburg shortly after midnight Tuesday, April 28. The most significant damage occurred at a warehouse on E Court St, where ten skylights were blown out, and a large metal panel was pulled from the side of the building. The tornado continued southeastward almost parallel to E Court Street, causing tree damage on both sides of the road. Minor roof damage was noted at a house on Auburn Ave. The tornado lifted just before reaching U.S. Highway 412.

A significant multi-day severe weather event affected the Mid-South as a deepening surface low and cold front traversed the central United States. On April 27, 2026, a northward-lifting warm front introduced tropical moisture, with dewpoints rising into the upper 60s and lower 70s. This environment, supported by a strong 500 mb jet streak, produced MLCAPE values exceeding 2,500 J/kg and effective bulk shear values often surpassing 40 knots.

The event unfolded in several phases. Starting late Monday, April 27, supercells across southern Missouri and northern Arkansas consolidated into a Mesoscale Convective System (MCS). This MCS tracked southward through Tuesday morning, bringing damaging winds, large hail, and two weak tornadoes. On Tuesday, a secondary shortwave trough triggered two additional rounds of severe weather. The first occurred late Tuesday afternoon into the early evening, featuring organized convection with bowing line segments that produced damaging winds, large hail, and a weak tornado in northeast Arkansas. The second round developed immediately after the first round had moved into Middle Tennessee and north Alabama, bringing further damaging winds from Tuesday evening through early Wednesday morning, along with locally heavy rainfall that caused flash flooding. By early Wednesday morning, April 29, the cold front exited the region, ending the threat and returning the area to cooler, drier conditions.
