Sunny start, mild highs and a chance of showers Wednesday night
Environment Canada observations early Tuesday indicate mainly sunny skies over North Bay with a temperature of 3.1°C at 8:01 a.m. The agency reported a rising barometer at 103.4 kPa, visibility extending to 48.3 km and a dew point close to freezing at -0.2°C, producing a relative humidity of 79%. The wind was from the east‑northeast at about 8 km/h.
Forecasters expect daytime temperatures to climb quickly under the sunshine, reaching a high of around 13°C. The UV index is forecast to be 3 (moderate), so brief sun protection for extended outdoor activity is advisable.
Hourly and short-term outlook
The hourly forecast shows a steady warming trend through the day, with temperatures rising from the low single digits this morning into the low teens by mid‑afternoon. Winds are expected to ease late in the morning from the current easterly direction.
- 9 a.m. — 3°C
- Noon — 8°C
- 3 p.m. — 12°C
- 5 p.m. — 13°C (high)
- Tonight — clear, low near 1°C
Morning fog patches are expected to dissipate early, improving visibility for drivers. Any lingering low clouds should break as the sun warms the near‑surface layer.
Into midweek and beyond
Wednesday is projected to remain predominately sunny for a large portion of the day, with increasing cloud cover around midday. The forecast carries a 40 percent chance of showers Wednesday night, as periods of cloud and moisture move into the region. Temperatures on Wednesday should be slightly warmer, with a high near 15°C.
Through the rest of the week the pattern looks relatively benign with daytime highs hovering in the low to mid‑teens and nights generally close to or just above freezing. The seven‑day guidance highlights:
| Day | High | Night | Notes |
|---|---|---|---|
| Tuesday | 13°C | +1°C | Sunny; fog lifting; moderate UV |
| Wednesday | 15°C | 6°C | Increasing cloudiness; chance of showers tonight |
| Thursday | 13°C | -1°C | Sunny |
| Friday | 13°C | +3°C | Sunny |
Weekend guidance indicates continued mild afternoons with a mix of sun and cloud and a few chances of showers, particularly over Saturday night into Sunday. Overnight lows will vary but generally trend a few degrees above typical seasonal minima.
Context and impacts
Current temperatures and the rising pressure reflect stable conditions that favour sunshine and good travel weather for this part of Ontario. The rapid warm‑up from morning to afternoon is typical when fog dissipates and solar heating increases; drivers should allow extra time for clearing fog in the early hours. The approaching cloud and the chance of showers later in the week could lead to wetter road surfaces and reduced visibility for short periods, but no significant precipitation amounts are indicated at this time.
For those planning outdoor activities: take advantage of the sunny, mild mid‑week afternoons, and keep a compact rain layer handy for the possibility of showers Wednesday night into the weekend. Environment Canada remains the source for updates and any advisories issued for the region.
