Freezing Fog Ushers in the Day
Ottawa is waking up to a hazy morning, with freezing fog limiting visibility to just 0.4 km. The temperature hovered at -3°C, but it felt chillier, with the wind chill making it feel like -6°C. The air is saturated, with 100% humidity, while the barometric pressure is at 101.9 kPa and rising, signaling a shift in weather patterns. Light winds from the east-northeast at 8 km/h add a slight bite to the air.
The forecast promises the fog patches will dissipate as the day unfolds, but don’t get too comfortable—rain will make an entrance this afternoon.
Expect 5 to 10 mm of precipitation, with winds picking up to 20 km/h from the east later today. Temperatures will climb to a high of 6°C, so perhaps trade the snow boots for rain boots.
Tonight: Rain Persists
Tonight, rain continues with another 10 mm expected. The temperature will hold steady at 7°C, while winds will ease, becoming light after midnight. It’s the kind of night that begs for an umbrella and a waterproof jacket if you’re venturing out.
Monday: A Warm Yet Wet Start to the Week
Monday’s high of 10°C might tempt you to pack away the heavy winter gear, but don’t be fooled—it’s still December! Rain will taper off in the morning, giving way to a cloudy sky with a 40% chance of showers through the afternoon. Showers are likely to return in the late afternoon, with southwest winds at 20 km/h adding to the damp feel.
As Monday night rolls in, the low will dip slightly to 1°C, and the sky will stay cloudy with a lingering chance of rain.
New Year’s Eve and Beyond
Tuesday, December 31, is shaping up to be a relatively calm day with cloudy skies and a high of 3°C. Clouds will remain through the night as temperatures hold at 1°C.
As we ring in the New Year, Wednesday brings periods of snow or rain and a high of 2°C. By nightfall, there’s a 60% chance of flurries as temperatures dip to -4°C.
Historical Weather Trivia
On this date, Ottawa’s historical high was a balmy 12°C, recorded in 1984, while the chilliest low was -31.3°C in 1933. It’s safe to say we’re sitting comfortably in the middle today!
