Sault STE. MARIE – WEATHER DESK – Sault Ste. Marie is heading into a wet and unsettled stretch of weather, with a Special Weather Statement in effect for Sault Ste. Marie – St. Joseph Island. Environment Canada says the region can expect 20 to 40 mm of rain from Sunday morning through late Monday morning, with locally higher amounts possible.
Forecasters also warn that the frozen or nearly saturated ground will not absorb rain well, raising the risk of ponding and localized flooding concerns.
Today’s Weather Overview
At 7:00 AM EDT Sunday, April 12, conditions at Sault Ste. Marie Airport were already damp and raw. The city was reporting light rain, a temperature of 2.0°C, pressure at 102.0 kPa and falling, humidity at 91 percent, and ESE winds at 21 km/h gusting to 33 km/h. Visibility was down to 10 km, which fits the gloomy start to what looks like a very wet day.
Environment Canada says periods of rain will continue through the day, with rain mixed with light snow early this morning, along with a risk of freezing drizzle early and a risk of a thunderstorm late this afternoon. Rainfall amounts of 5 to 10 mm are expected today, while winds become south 20 km/h gusting to 40 and temperatures rise to a high near 6°C.
Tonight and the Next Three Days
Tonight looks especially active. Environment Canada is calling for periods of rain, a risk of a thunderstorm this evening and after midnight, and a local rainfall amount of 15 to 25 mm. Winds shift from southeast 20 km/h gusting to 40 to southwest 20 gusting to 40 later in the evening. One of the more unusual parts of the forecast is the temperature trend: it is expected to rise to 12°C this evening and then hold steady, which is why the overnight period is flagged as an abnormal temperature trend.
On Monday, April 13, showers should taper off in the morning, followed by a mix of sun and cloud. Winds ease through the day, and temperatures are forecast to fall to 8°C in the afternoon. Monday night turns cloudy with a low of 1°C.
The pattern stays unsettled beyond that. Tuesday brings cloudy skies with a 60 percent chance of rain and a high of 6°C, while Wednesday carries a 60 percent chance of showers and a high of 8°C. Thursday looks wetter again, with showers and a high of 11°C. Environment Canada also says another episode of significant rainfall is possible Tuesday, and notes that rainfall warnings could still be issued for some areas if amounts trend higher.
Travel and Local Impact
The biggest concern is not snow or ice this time, but water. Because the ground is still frozen or nearly saturated, this rain will have a harder time soaking in. That makes low spots, ditches, poorly drained roads, and urban puddling more likely problems through Sunday and into Monday. The added risk of thunderstorms later today and tonight could also briefly increase rainfall intensity.
Wardrobe Recommendations
This is a rain gear day in the Sault. A waterproof jacket, waterproof footwear, and an umbrella are the smart choices. With gusty winds and wet conditions, it will feel chilly early on even though temperatures climb later. By tonight, lighter rain gear may be enough as the air turns much milder, but it will still be a messy evening to be outdoors. This is an inference based on the official temperature, wind, and rainfall forecast.
Weather Trivia
Spring in Sault Ste. Marie often turns dramatic when colder northern air, milder southern air, and Great Lakes moisture all meet at once. That is how the city can go from rain mixed with snow in the morning to thunderstorm risk and double-digit temperatures by evening. This is an inference based on the official forecast pattern for Sunday into Sunday night.
In Conclusion
Sault Ste. Marie weather update for April 12, 2026: a Special Weather Statement is in effect as 20 to 40 mm of rain, gusty winds, and thunderstorm risk move into the region through Monday.
