Winter Weather Advisory: April Storms Hit Midwest & Great Lakes

April may be here, but winter is refusing to leave. A powerful and wide-ranging late-season storm system is currently impacting millions of residents across the Upper Midwest and Great Lakes, bringing hazardous conditions that forecasters say could last through Easter weekend. The National Weather Service has issued winter storm warnings, watches, and advisories for areas spanning Minnesota, Michigan, South Dakota, and beyond — a jarring reminder that spring weather in the northern United States is rarely predictable.

Whether you're trying to figure out if your area is affected, planning Easter weekend travel, or just trying to stay safe, here's everything you need to know about the current winter weather advisory situation and what's still to come.

Current Winter Storm Warnings and Advisories in Effect

Starting April 1, 2026, at midnight, a winter weather advisory went into effect across much of south-central Minnesota as precipitation transitioned from rain to a dangerous wintry mix. A stronger winter storm warning extends eastward into Wisconsin, covering areas expected to receive the heaviest accumulations.

According to the KEYC News report, the advisory covers the region as a wintry mix — including rain, freezing rain, sleet, and snow — moves through overnight Wednesday into Thursday morning. Temperatures are expected to drop into the low-to-mid 30s during this window, making roads and sidewalks especially treacherous.

The advisory is currently in effect through noon Thursday, April 3, but conditions won't end there. More mixed precipitation is forecast to return Friday afternoon and continue overnight into Saturday, with wind gusts up to 40 mph possible on Saturday.

Snowfall Totals, Ice, and Wind: What to Expect

The headline numbers from this storm are significant. As reported by AccuWeather via Yahoo News, parts of South Dakota, Minnesota, and Michigan are expected to see 6 to 12 inches of snow from April 1 through April 3, combined with sustained winds and gusts reaching 40 mph.

This combination of heavy, wet snow and strong winds creates a particularly dangerous scenario:

• Blowing and drifting snow will significantly reduce visibility on highways and rural roads
• Wet, clinging snow can weigh down tree branches and power lines, increasing the risk of outages
• Ice storm conditions are also forecast for Michigan, Wisconsin, and parts of the broader Great Lakes region
• Freezing rain and sleet will create black ice on untreated surfaces, especially overnight

AccuWeather explicitly warned that "this storm can result in dangerous travel from the Dakotas through the Great Lakes through Thursday night," urging residents to avoid unnecessary trips during the peak of the storm.

Which States and Regions Are Most Affected?

The storm system is sprawling, and its effects are being felt across a wide swath of the country. According to MSN Weather's storm map coverage, snowstorms are currently on track to hit nine states. The core impact zone includes:

• South Dakota — heavy snow and wind, among the hardest-hit areas
• Minnesota — winter weather advisory and storm warning zones across much of the state
• Michigan — both snowfall accumulations and ice storm threats
• Wisconsin — winter storm warning in effect, freezing rain possible
• Iowa — additional storm impacts expected into Easter weekend
• North Dakota — caught in the broader system affecting the Dakotas

A second storm system projected for Easter weekend (April 4–5) is expected to bring additional snow and ice to Minnesota, South Dakota, Iowa, Wisconsin, northern Michigan, and as far east as far northern Maine.

Easter Weekend Storm: What's Still Coming

If you thought the first storm was the end of it, think again. Forecasters are tracking a separate weather system that is expected to impact much of the same region over Easter weekend. This additional storm is projected to bring another round of snow and ice to:

• Minnesota
• South Dakota
• Iowa
• Wisconsin
• Northern Michigan
• Far northern Maine

For families planning Easter Sunday gatherings or holiday travel, this is critical information. Road conditions may remain poor or deteriorate again after a brief improvement Friday morning. Anyone planning to travel across the Upper Midwest or Great Lakes region this weekend should monitor the latest National Weather Service updates closely and have a flexible backup plan.

How to Stay Safe During a Winter Weather Advisory

Late-season storms catch people off guard precisely because we've mentally shifted to spring mode. But a winter weather advisory demands the same precautions as any January storm. Here's what safety experts recommend:

Before the Storm

• Stock your vehicle with a Emergency car kit including jumper cables, a blanket, flashlight, and first aid supplies
• Make sure you have an Ice scraper and snow brush in your car — don't assume the one from last winter is still there
• Fill your gas tank before the storm arrives
• Check your snow shovel and ice melt supplies at home
• Charge all devices and have a portable power bank ready in case of outages

During the Storm

• Avoid driving if at all possible — black ice and blowing snow create near-zero visibility conditions
• If you must drive, reduce speed dramatically and increase following distance
• Watch for downed power lines, especially after wet, heavy snow loads
• Keep a weather alert radio or reliable app for real-time NWS updates
• Never run a generator indoors — carbon monoxide poisoning is a leading cause of storm-related deaths

After the Storm

• Clear snow from around exhaust pipes before starting your car
• Use roof rake for snow removal to prevent ice dams on your home's roof
• Be cautious of refreezing overnight even after daytime melting

Why Late-Season Winter Storms Are Particularly Dangerous

Meteorologists often point out that late-season storms like this one can be more dangerous in certain ways than those in the heart of winter. Several factors make April storms uniquely hazardous:

• Complacency: People have mentally moved on from winter preparedness — snow tires may already be swapped out, winter gear is packed away
• Wet, heavy snow: Warmer ambient temperatures mean the snowfall that does occur tends to be wetter and heavier, putting more stress on trees, power lines, and roofs
• Mixed precipitation: The temperature window between rain and snow means more freezing rain and sleet, which create glassy, unpredictable road surfaces
• Infrastructure strain: Road crews and utility companies may be less prepared for a major storm event in April than they would be in December

The current system checks all of these boxes, which is why forecasters are treating it seriously despite its unusual timing.

Frequently Asked Questions About Winter Weather Advisories

What is the difference between a winter weather advisory, a winter storm watch, and a winter storm warning?

A winter weather advisory means conditions will cause significant inconveniences and may be hazardous but are not severe enough for a warning. A winter storm watch means severe winter conditions are possible within 48 hours — be prepared. A winter storm warning is the most serious: severe conditions are imminent or already occurring, and you should take immediate action to protect yourself.

How much snow is expected from the current storm?

Forecasters are projecting 6 to 12 inches of snow in parts of South Dakota, Minnesota, and Michigan between April 1 and April 3. Combined with 40 mph wind gusts, drifting will make some areas significantly worse.

Will Easter weekend be affected?

Yes. A second storm system is projected to impact Minnesota, South Dakota, Iowa, Wisconsin, northern Michigan, and far northern Maine over Easter weekend (April 4–5). Anyone planning holiday travel in these regions should check forecasts closely and consider delaying or adjusting plans.

Is an ice storm warning in effect?

An ice storm threat has been forecast for Michigan, Wisconsin, and the broader Great Lakes region. While not all areas have ice storm warnings specifically, freezing rain and sleet are expected to create dangerous icy conditions, particularly overnight.

When does the current winter weather advisory expire?

The winter weather advisory currently in effect for much of south-central Minnesota runs through noon on Thursday, April 3. However, conditions are expected to deteriorate again Friday afternoon with another round of mixed precipitation continuing into Saturday.

Conclusion: Don't Let Your Guard Down This Easter Weekend

This late-season storm is a stark reminder that winter doesn't follow the calendar. With 6 to 12 inches of snow, ice storm threats, and 40 mph winds already battering the Upper Midwest and Great Lakes, and a second storm looming over Easter weekend, residents across nine states need to remain vigilant through at least the first full weekend of April.

Stay connected to your local National Weather Service alerts, keep your vehicle and home prepared, and avoid non-essential travel through Thursday and again this weekend. The conditions may be unusual for early April, but the dangers they pose are very real.
