You need to keep your winter gear handy this morning, but don’t get too attached to it. A significant shift in weather patterns brings a messy mix of precipitation and a major warm-up to Saint John this weekend.

According to the latest data from Environment Canada, we face a roller coaster forecast starting with a deep freeze today and peaking with double-digit highs by Sunday.

Friday: The Deep Freeze

Current conditions at the Saint John Airport show temperatures sitting around -7°C, but the wind chill tells a colder story. You will feel values closer to -19 this morning and -9 this afternoon. While we see a mix of sun and cloud today, the high struggles to reach -4°C. The UV index remains moderate at 3.

Saturday: Messy Transition and Freezing Rain Risk

Saturday marks the transition point, and it looks messy. Clouds roll in tonight, and by early Saturday morning, we expect flurries.

Drivers should exercise caution early Saturday. The forecast indicates a risk of freezing rain in the morning hours before the temperature rises enough to change precipitation into rain showers. Winds pick up significantly, shifting to the south at 20 km/h and gusting up to 40 km/h. The temperature climbs to a high of +4°C, though the morning wind chill still bites at -6.

Sunday: Rain and Double-Digit Highs

By Sunday, March 8, the warm air fully takes over. We expect a high of 11°C—a stark contrast to Friday’s wind chill. However, you will need an umbrella as showers remain in the forecast throughout the day.

Looking Ahead to Next Week

The warmth lingers briefly into the start of the workweek. Monday and Tuesday feature a mix of sun and cloud with highs of 8°C and 10°C, respectively. However, reality returns by Wednesday, with temperatures dropping back to the freezing mark and a renewed chance of flurries.
