As summer slowly fades, parts of northern Minnesota are already feeling the chill. Tonight, another round of frost is expected, especially in rural and low-lying areas.
If you’re a farmer or gardener in the region, it’s time to take precautions as cooler temperatures could harm sensitive plants. Here’s a clear look at what to expect in the coming days.
Frost Warning for Saturday Night
Northern Minnesota will experience clear skies and calm winds overnight—ideal conditions for rapid cooling. As a result, temperatures are expected to fall into the mid-30s, with some areas nearing freezing.
Areas affected: International Falls, the Iron Range, and the Arrowhead region
Low temperatures: Around 33°F–36°F
Conditions: Calm winds, clear skies, chilly night
While a widespread freeze isn’t expected, patchy frost could still damage unprotected plants. If you have a garden or sensitive outdoor plants, it’s best to:
Cover them with cloth or blankets
Bring potted plants indoors
Delay early morning watering
Sunday: Chilly Morning, Mild Afternoon
After a frosty start, temperatures will slowly warm up during the day. Sunday will be mostly sunny with highs reaching the upper 50s to mid-60s. It’ll still feel cool, but the sunshine will offer some relief.
Daytime high: 58°F to 65°F
Evening low: Back into the mid-30s
Frost risk: Patchy frost possible again overnight
Another cold night is expected on Sunday, so keep your plants protected for one more round.
Monday-Tuesday: Rain and Thunderstorms Incoming
The calm, cool weather won’t last long. Starting Monday afternoon, a new weather system will bring in scattered showers and possibly a few thunderstorms.
Rain chances: Increase by Monday afternoon
Storm potential: Some storms could be strong, especially late Monday into Tuesday
Travel impact: Wet roads and lower visibility may affect commutes
While the rain is a welcome change for dry soil, keep an umbrella handy and drive carefully during the first half of the week.
Tuesday Onward: Warmer Days Return
By Tuesday and beyond, northern Minnesota will see a return to more seasonable temperatures. Though the rain may linger, daytime highs will gradually rise.
Expected highs: Upper 60s to low 70s by midweek
Overall outlook: Warmer, but slightly unsettled with rain chances off and on
