By iSkyNews | March 28, 2025

A significant severe weather outbreak is expected Sunday, March 30, 2025, as over 25 million Americans are in the Enhanced Risk zone for dangerous thunderstorms, according to the latest Day 3 Outlook issued by the NOAA Storm Prediction Center.

Communities across the Ohio Valley, Mid-South, and Lower Missouri and Tennessee River Valleys could face very large hail, destructive wind gusts, and strong tornadoes, including the cities of Indianapolis, Memphis, Nashville, St. Louis, and Cincinnati.

Outlook Breakdown:

Enhanced Risk (ENH):235,853 sq. mi. | 25.7 million people
- Major cities: Indianapolis, Memphis, Nashville, St. Louis, Cincinnati
Slight Risk (SLGT):285,501 sq. mi. | 45.9 million people
- Includes: Chicago, Detroit, Columbus, Cleveland, Pittsburgh
Marginal Risk (MRGL):196,804 sq. mi. | 36.5 million people
- Includes: Houston, Dallas, Austin, Fort Worth, Milwaukee

What to Expect:

Ohio Valley: A favorable overlap of surface heating and low-level wind fields creates the potential for discrete supercells. With effective shear vectors orthogonal to the cold front, the environment supports strong tornadoes, very large hail, and severe winds.

Mid-South: Heating and moisture return are expected to break through any morning cap, possibly leading to late-afternoon development. A pre-frontal confluence zone may set up, increasing the likelihood of strong tornadoes in discrete storms.
East Texas/Sabine Valley: Convection is expected along a dryline with discrete supercells, capable of producing giant hail, damaging winds, and isolated tornadoes before a cold front surges in, leading to storm mergers and line formation.

📍 Stay Weather-Aware: Sunday’s setup holds the potential for long-track tornadoes and damaging wind events. Residents are urged to review their safety plans, ensure weather alerts are active, and stay tuned to iSkyNews.com for live updates and storm tracking coverage.
