This article translates a forthcoming severe-weather event into clear, science-based guidance for residents, responders, and decision-makers. It explains the meteorological setup behind the forecast, outlines the primary threats in southern Minnesota and western Wisconsin, and offers practical safety steps to reduce harm as the storm system unfolds on Monday, April 13, 2026.
Forecast Overview
The National Weather Service has issued an enhanced risk for severe weather, signaling conditions favorable for supercells capable of rapid intensification. Forecasters emphasize the potential for tornadoes, very large hail, and damaging wind gusts as the storm moves through the region this Monday afternoon and evening.
Storm dynamics and risk factors
Scientists note that a warm front is likely to stall somewhere across southern Minnesota, creating a zone where atmospheric shear and instability align to produce tornadic activity. The combination of strong wind fields and instability can lead to rapid intensification of storms, especially those near the stalled front.
The exact location of the greatest danger remains uncertain until forecast tools converge on the boundary location.
Timing and geography
Most storm development is anticipated between about 4 p.m. and 6 p.m. local time on Monday, April 13, 2026. The most dangerous corridor is expected to lie along and just south of the stalled warm front, where the tornado threat could be strongest.
People in southern Minnesota and western Wisconsin should monitor updates closely, as small shifts in the front position can shift risk areas.
Threats and Impacts
The forecast calls for multiple hazards that could pose serious risks to people and property, including potential impacts to power, transportation, and public safety.
- Tornadoes are possible, with the highest threat near the stalled front and given the potential for a few strong tornadoes.
- Large hail could reach 2–3 inches in diameter in the strongest cells, capable of causing significant damage to vehicles and structures.
- Damaging wind gusts up to 70 mph may accompany fast-moving thunderstorms, posing hazards to trees, power lines, and unsecured objects.
- The weather event poses risks to property, power infrastructure, transportation networks, and public safety if warnings are issued and not acted upon.
Quick, widespread weather changes can disrupt daily life. Communities should be ready for rapid decision-making, timely alerts, and responsive sheltering as conditions evolve.

Preparedness is essential to reduce harm during this potentially dangerous severe-weather episode. Local residents, schools, businesses, and emergency managers should have plans that enable rapid sheltering and communication when warnings are issued.
- Know where to seek shelter: identify the strongest part of a building (typically an interior room on the lowest floor, away from windows).
- Develop a family emergency plan and practice it. Assign roles (who checks warnings, who leads sheltering, who handles pets).
- Protect mobile homes and outdoor structures by seeking sturdier shelter if possible and securing loose objects that could become projectiles.
- Stay connected with weather updates through NOAA Weather Radio, official apps, and local media. Keep devices charged and have a go-bag ready with essentials.
- Vehicle safety: if you are driving, seek substantial shelter if a tornado warning is issued; if not feasible, find a sturdy building or lie flat in a low-lying area away from trees and cars when necessary.
- School and workplace planning: ensure indoor locations are identified for shelter during potential tornado warnings and practice drill protocols when alerts occur.
Official Guidance and Community Readiness
Officials urge the public to stay weather-aware and heed warnings from the National Weather Service. Preparedness and rapid response are critical to minimizing harm, protecting lives, and ensuring continuity of essential services during this severe-weather episode.
Final Take from an Experienced Meteorologist
With three decades in the field, I’ve observed that the most dangerous severe-weather events hinge on two factors: timely, accurate forecasts and swift action at the community level.
This setup offers a real opportunity for protective decisions—seek shelter when warnings are issued and monitor updates closely.
Avoid risky behaviors during the peak of activity.
