Northern Ontario’s remote First Nations communities are transitioning into typical fall conditions with cooler temperatures, breezy winds, and occasional periods of cloud cover. As the barometric pressure trends offer insights into these upcoming changes, weather patterns across these areas will bring both stable and shifting conditions.
Today’s Weather Overview:
Sandy Lake:
- Current Temperature: 7°C

- Conditions: Partly cloudy with a low chance of rain.
Wasaho Cree Nation (Fort Severn):
- Current Temperature: 6°C
- Wind: 20 km/h from the west, gusting up to 30 km/h.
- Barometric Pressure: 101.0 kPa, showing a slow rise. This points to improving conditions, though still cool and breezy.
- Conditions: Mostly cloudy with potential clearing in the late afternoon.
Webequie:
- Current Temperature: 6°C
- Wind: From the northwest at 20-25 km/h, with gusts reaching 35 km/h by afternoon.
- Barometric Pressure: 101.3 kPa, rising slightly, which suggests stabilizing weather after early morning clouds.
- Conditions: Cloudy skies clearing by late afternoon, with a mild breeze.
Marten Falls:
- Current Temperature: 7°C
- Wind: Light at 15 km/h, increasing to 25 km/h in the afternoon.
- Barometric Pressure: 101.5 kPa, steady, indicating calm conditions with minimal chances of rain.
- Conditions: Partly sunny, with a few scattered clouds but no rain expected.
Tomorrow’s Forecast (October 2):
Across all communities, expect:
- Highs of 13-16°C.
- Lows of 3-5°C at night.
- Winds easing overnight but picking up again in the afternoon, generally from the northwest.
- Partly cloudy conditions with a 30-40% chance of scattered showers, particularly in Kasabonika and Bearskin Lake.
The Importance of Barometric Pressure in Weather Forecasting:
Barometric pressure measures the weight of the air above us and plays a crucial role in predicting weather. Low pressure generally brings stormy or wet conditions, as the air rises and cools, leading to cloud formation and precipitation. Conversely, high pressure signals clear, stable weather, as the air is descending, preventing cloud formation. A rising barometer usually indicates improving conditions, while a falling barometer can be an early warning of approaching storms or unsettled weather. By tracking these trends, meteorologists can forecast the likelihood of rain, wind, and temperature shifts in advance.
Wardrobe Recommendations:
Residents should dress in layers to accommodate the cool temperatures and breezy winds. A light jacket with a windproof layer is recommended for the afternoon, while an insulated layer may be necessary for the evening and overnight, particularly in areas where the temperature dips near freezing.
