DALLAS, Texas — A highly conditional but potentially dangerous severe weather setup is in place for Sunday, April 12, as forecasters warn that if storms are able to develop across the Texas, Oklahoma, and Kansas corridor, the environment will be more than capable of supporting large hail, damaging winds, and a few tornadoes from San Antonio all the way north to Wichita.
The greatest severe weather potential is focused along a corridor stretching from San Antonio, Texas through Dallas, Oklahoma City, and Tulsa up to Wichita, Kansas, according to the latest outlook issued by Max Velocity Weather, with a Slight Risk zone covering the heart of this corridor as of Sunday, April 12, 2026.
Cities and States in the Risk Zone
- Texas: San Antonio, Dallas, Lubbock, Amarillo, and Houston sit within the risk zone — San Antonio to Dallas corridor carries the highest local concern
- Oklahoma: Oklahoma City and Tulsa are directly inside the Slight Risk zone where tornado potential is greatest
- Kansas: Wichita falls at the northern end of the primary severe weather corridor
- Missouri: Springfield and surrounding areas sit within the broader Marginal Risk zone
- Arkansas: Little Rock and surrounding communities fall within the outer Marginal Risk zone
- Louisiana/Mississippi: Shreveport, Jackson, and Memphis sit on the eastern edge of the broader threat area
Primary Threats
Sunday’s setup is described as highly conditional — meaning the threats below only materialize if storms can actually develop and fire. If they do, forecasters say the atmosphere will support:
- Large hail — The environment has enough instability to support significant hail-producing thunderstorms across the San Antonio to Wichita corridor
- Damaging winds — Straight-line wind damage is possible with any storms that develop Sunday afternoon and evening
- Tornadoes — A few tornadoes cannot be ruled out, particularly across the Oklahoma City, Tulsa, and Dallas metro areas where atmospheric conditions are most favorable
Why This Matters for Texas and Oklahoma
The core of Sunday’s threat sits directly over some of the most populated metro areas in Texas and Oklahoma. Cities like Dallas, Oklahoma City, and Tulsa are no strangers to severe weather, but a setup where tornadoes are possible — even under conditional circumstances — demands attention from residents across the region.
The critical factor forecasters are watching is whether morning convection — storms that fire overnight and into the early morning hours — will stabilize the atmosphere and prevent afternoon storm development. If morning storm activity exhausts the available energy and lift remains absent through the afternoon, storms may simply not develop and the threat fizzles out entirely…
