Minnesota faced a major March snowstorm on the weekend of March 15–16, 2026, producing widespread disruptions across the state. The storm—under a NEXT Weather Alert into Monday—was forecast to deliver more than 1 foot of snow in many locations, with isolated amounts above 18 inches and snowfall rates of 1–3 inches per hour. Strong winds of 30–50 mph raised the risk of whiteout conditions and widespread travel hazards. In response, Gov. Tim Walz authorized the Minnesota National Guard to support emergency operations as communities prepared for power outages, road closures and cancelled flights.
Key Takeaways
- NEXT Weather Alert in effect into Monday after the March 15–16 storm; forecasts called for many areas to receive over 12 inches of snow and some spots over 18 inches.
- Snowfall rates were expected at 1–3 inches per hour with winds of 30–50 mph, creating potential whiteouts and rapid visibility loss.
- More than 600 flights at Minneapolis–St. Paul International Airport were cancelled as of 9:30 p.m. Saturday, according to FlightAware.
- Gov. Tim Walz signed an executive order authorizing the Minnesota National Guard; four armories were positioned in Albert Lea, Fairmont, Owatonna and Redwood Falls for possible activation.
- Local authorities declared snow emergencies in multiple cities; several cultural institutions and businesses announced closures for Sunday.
- A multi-vehicle crash on I‑35 near Elko New Market just before 8 p.m. Saturday injured one person; injuries were not considered life-threatening.
- Civic services were affected: Minneapolis and St. Paul opened free/low-cost parking options, and St. Paul announced no garbage pickup on Monday due to the storm.
Background
Late-season March storms remain a known hazard in Minnesota, where spring-pattern variability can still produce heavy snow and powerful winds. Even after milder days, residents and officials often prepare for abrupt winter returns; state emergency protocols allow rapid mobilization of resources when forecasts indicate high-impact conditions. The state government has precedent for activating the National Guard for severe winter events to assist with rescues, supply distribution and transportation support.
Minneapolis–St. Paul International Airport is a major regional hub, so significant cancellations at MSP quickly ripple through national and international travel schedules. Road and transit systems in the Twin Cities and greater Minnesota are particularly vulnerable when high snowfall rates combine with strong winds, which can produce drifting and extended closures. Local governments—city mayors, public works and transportation agencies—typically announce parking measures and snow emergencies in advance to speed clearance and reduce stranded vehicles.
Main Event
Forecast models and live observations on Saturday indicated the storm would peak late Saturday into Sunday, prompting a NEXT Weather Alert that extended into Monday. The strongest bands were expected to deliver rapid accumulation—1 to 3 inches per hour—across stretches of southern and central Minnesota, with localized heavier totals exceeding 18 inches. Meteorologists warned that wind-driven snow could create whiteout conditions and severely reduced mobility on highways and secondary roads.
Gov. Tim Walz authorized the Minnesota National Guard by executive order ahead of the event; the Guard placed personnel and tracked SUSV vehicles at armories in Albert Lea, Fairmont, Owatonna and Redwood Falls to be ready for rescue or transportation missions if road conditions deteriorated. Colonel John McCrae, director of operations for the Guard, said armories were positioned so units could respond quickly to local needs.
Transport and commerce were visibly affected. Airlines advised travelers to rebook as the MSP system absorbed more than 600 cancellations for Sunday as of 9:30 p.m. Saturday. Twin Cities officials announced snow emergencies—effective 9 p.m. Sunday—to facilitate plowing and clear arterial routes; both Minneapolis and St. Paul opened specific parking lots and ramps to help residents relocate vehicles ahead of enforcement.
Incidents on the roads underscored the hazard: a preliminary Minnesota State Patrol investigation found a primary crash on I‑35 near Elko New Market shortly before 8 p.m. Saturday, when a vehicle struck a guardrail and became disabled, triggering a secondary multi-vehicle collision. One person sustained non-life-threatening injuries, and MnDOT reported major delays as crews and emergency services responded.
Analysis & Implications
High snowfall rates combined with strong winds concentrate risk: even a storm with average totals can produce prolonged travel paralysis when visibility collapses and drifting closes corridors. Emergency services face two simultaneous stresses—responding to crashes and protecting stranded motorists—while trying to keep primary arterials open for essential movement. The Guard’s deployment posture reflects the expectation that some areas may be inaccessible to standard vehicles without tracked or specialized equipment.
Aviation disruptions at MSP add an economic dimension beyond immediate safety concerns. Hundreds of cancellations inconvenience travelers and create downstream labor and cargo disruptions; hotels, rental car operators and local businesses near the airport typically see knock-on effects. For freight and supply chains that rely on timely air connections, delays can shift deliveries and inventory cycles for retail and medical suppliers.
Municipal operations—trash collection, parking enforcement, transit scheduling—face compressed decision windows once accumulations exceed plow capacity and staffing thresholds. St. Paul’s decision to suspend Monday garbage pickup reflects the trade-offs cities make when prioritizing emergency and snow-clearing operations. Residents who rely on curbside services, or whose work depends on predictable transit, may face disruptions for several days after the storm.
Looking ahead, forecasting placement uncertainty 24 hours out means communities should plan for worst-case scenarios even if final band placement shifts. Resource staging (fuel, shelter space, tow and recovery assets) remains an effective mitigating strategy when rapid-onset, high-rate snowfall is expected.
Comparison & Data
| Metric | Forecast / Reported |
|---|---|
| Typical accumulation cited | Many areas >12 inches; isolated >18 inches |
| Snowfall rate | 1–3 inches per hour |
| Wind | 30–50 mph (gusts creating whiteouts) |
| MSP cancellations (as of 9:30 p.m. Sat) | >600 flights (FlightAware) |
The table summarizes the primary numeric forecasts and observed disruption figures reported during the event. Rapid accumulation and high winds are the two factors that most heavily influenced public-safety and transportation decisions, including the Guard authorization and municipal snow-emergency declarations.

Unconfirmed
- Final statewide total of storm-related damage and economic losses is not yet available and will require post-storm assessments.
- Exact final placement of the heaviest snow band remained subject to model shifts and was still uncertain 24 hours before peak accumulation.
- Any additional storm-related injuries or late reports of infrastructure damage were still being compiled by local authorities at the time of the last update.
Bottom Line
This March storm was a high-impact late-winter event: rapid accumulations, strong winds and the potential for whiteout conditions combined to create immediate public-safety and transportation challenges. The state’s preemptive authorization of the National Guard and municipal snow-emergency declarations were intended to accelerate response, prioritize road clearance and protect residents who might become stranded.
Residents should heed local emergency orders, avoid nonessential travel during peak conditions, and follow official guidance on parking and sheltering. Watch for updates from local public-safety agencies and transportation authorities as crews shift from response to recovery and as final snowfall totals and impacts are tallied.
