Weather Forecast – Classic Late May Blend of Sun, Warmth, and a Chance of Thunder
A Mild Start with Calm Winds and Climbing Temperatures
Fort Frances, Rainy River & Red Gut First Nation – Tuesday, May 27, 2025: It’s a comfortable morning in the Rainy River District, where the temperature sits at 11.6°C as of 6:00 AM, under a sky that’s starting to brighten up — even if it’s not officially “observed” yet at the weather station. Humidity sits at 69%, the dew point is 6.1°C, and there’s a light southeasterly breeze at 6 km/h. The pressure is rising at 102.5 kPa, giving us a stable setup to start the day.
The forecast for today includes a mix of sun and cloud, with temperatures climbing to a comfortable high of 21°C. However, there’s a 30% chance of showers this afternoon, along with a risk of thunderstorms — especially in areas further west. It’s the kind of day that starts like summer and might end with a quick splash if the clouds build up fast. The UV index is 6, so even with some cloud, sun protection is important if you’re spending time outdoors.
Evening Showers Possible, Then a Calm, Mild Night
Tonight, expect partly cloudy skies with that lingering 30% chance of early evening showers and a possible thunderstorm, particularly before midnight. Once that passes, skies will begin to clear, and we’re looking at a mild overnight low of 10°C.
Midweek Sunshine with Just a Hint of Showers
Wednesday begins with sunshine in the morning, shifting to a mix of sun and cloud in the afternoon. There’s again a 30% chance of showers later in the day, but otherwise, it’s another beautiful spring day with a high of 23°C. The UV index rises to 7, so sun safety is a must. Wednesday night is expected to be clear with a low of 10°C, setting the tone for a spectacular late-week forecast.
Thursday and Friday: Full Sunshine and Summer-Like Heat
Thursday brings sunny skies and a high of 27°C — it’s looking like the best day of the week for anything outdoors. Thursday night stays clear with a low of 13°C, and Friday follows with more sunshine and a high of 26°C. A mild low of 11°C Friday night wraps up a stretch of perfect pre-summer weather.
What to Wear?
Start with layers this morning, but switch to short sleeves by mid-day. Bring along an umbrella or rain jacket if you’re out for the afternoon, especially with the thunderstorm risk. And definitely don’t forget sunglasses, a hat, and sunscreen — even through patchy clouds, UV levels are high.
Historic Temperatures for May 27
On this date, Fort Frances has reached a record high of 30.4°C, with a record low of -1.0°C. Today’s high of 21°C keeps us comfortably within the late-spring sweet zone — warm enough to enjoy, cool enough to keep the bugs (slightly) in check.
