Rain, Snow, or Sunshine? What Halloween Weather Looks Like Across Minnesota

The Halloween Storm of 1991 is one of Minnesota’s most infamous weather events, hitting just days after the Twins' World Series win. It began on October 31 with a mix of snow, rain, and sleet across southeast Minnesota, quickly escalating into a severe storm that caused widespread power outages due to heavy freezing rain.

Rochester avoided the worst ice damage thanks to slightly warmer temperatures. But other parts of the state were buried in snow. 28.4 inches fell in the Twin Cities and 36.9 inches in Duluth, the highest single-storm total in Minnesota history. Decades later, the storm remains scarred in people's memories and is a frequent topic of conversation as Halloween approaches each year.

Halloween is right around the corner, and by now you have probably already helped your kids pick out their costumes and have stocked up on candy to pass out.

You've probably already peeked at the long-range forecast, too. Trick-or-treating can be pretty miserable when it's nasty cold, raining, or even snowing. And, no kid wants to stretch their costume out over their winter coat.

The Old Farmer's Almanac Halloween Weather Forecast for Minnesota

The Old Farmer's Almanac has been predicting the weather since 1792 and claims they've been right more often than not over those 233 years.

The team at the Old Farmer’s Almanac just released their 60-day forecast for Minnesota. It doesn’t offer daily specifics, but breaks the weather down into stretches of days.

I looked ahead to the forecast for October 28 through 31 to get a sense of what to expect for Halloween.

Will Minnesota See Snow on Halloween?

According to the Almanac, cities across Minnesota, including Minneapolis, Mankato, Fairmont, Duluth, St. Cloud,  Faribault, Owatonna, and Rochester, will all experience the same type of weather.

Their prediction for Oct. 28-31 is a mix of sunshine followed by rain and snow, with chilly temperatures.

That sounds gross, so I found a second source. I checked the long-range forecast from AccuWeather, and their Halloween outlook doesn’t mention snow.

According to AccuWeather, parts of Minnesota could get some rain on the 30th. For Halloween day, they're forecasting highs in the low to mid-50s, with lows dipping into the mid-30s. It does look like it will be very windy, which could make it feel even cooler.

If you're planning to go trick-or-treating, keep an eye on the forecast. True Minnesotans know the weather forecasts are always changing.
