A short-lived but intense storm will drop upwards of 25 centimetres of snow on the Avalon tomorrow night, but there’s another system in the forecast threatening a second dose of snow.
PAL Airlines and Aerospace Meteorologist Brian Walsh says snow will begin on the Avalon and Burin Peninsulas late tomorrow afternoon, becoming heavy through the evening but tapering to flurries by Friday morning.
Storm Timeline for St. John’s-Metro:
Thursday 3 – 6 PM: Light snow developing around 5 PM. Wind increasing to northeast 30 gusting to 50 km/h.
Thursday 6 – 9 PM: Heavy snow. Blowing snow. Snowfall amount 5-8 cm. Wind northeast 40 gusting to 70 km/h.
Thursday 9 PM – Midnight: Heavy snow. Blowing snow. Snowfall amount 8-10 cm. Wind northeast 40 gusting to 70 km/h.
Friday 12 – 3 AM: Heavy snow tapering to light snow. Blowing snow. Snowfall amount 3-5 cm. Wind north 40 gusting to 70 km/h.
Friday 3 – 6 AM: Light snow. Blowing snow. Snowfall amount 2 cm. Wind northwest 40 gusting to 70 km/h.
Friday 6 – 9 AM: Flurries. Snowfall amount less than 2 cm. Wind northwest 40 gusting to 60 km/h.
Friday 9 AM – Noon: Flurries ending, then sun and cloud. Wind west 30 gusting to 50 km/h.
The system should run its course over a 12-hour period. When all is said and done, the Avalon could see upwards of 25 centimetres, while the Bonavista and Burin Peninsulas through Terra Nova will see closer to 10-15.
Snowfall Amounts Thursday Night-Friday Morning:
Avalon Peninsula: 15-25 cm
Bonavista Peninsula, Burin Peninsula, Terra Nova, and Clarenville: 10-15 cm
Central Newfoundland (east of Grand Falls-Windsor) and Connaigre Peninsula: 5-10 cm
Rest of Newfoundland: Less than 5 cm
Walsh cautions that winds gusting 60 to 80 km/h will be enough to reduce visibility, causing near white-out conditions at times.
Then, on Saturday, a second system looks to bring another 5 to 10 centimetres of snow to Eastern Newfoundland before it moves out.

Police Offer Safety Tips for Winter Driving
Meanwhile, the RNC is encouraging everyone to get themselves ready for the challenges of winter driving ahead of the system.
Heavy snow and blowing snow can cause rapidly deteriorating and dangerous road conditions.
The RNC says drivers should check weather conditions and road reports before heading out. Plan for extra travel time, slow down and increase your following distance. Assume conditions will be slippery in winter.
Some other tips include:
- Dress for winter in case you get stranded, even if you just plan to be in your car.
- Carry a cell phone in case you need to contact emergency services
- Prepare an survival kit in your vehicle. Suggested items include a shovel, salt, a blanket, booster cables, a flashlight, high energy foods, matches and a candle.
- Make sure your car is in good working order and that you have winter tires installed.
- Clear all windows of snow and ice before hitting the road.
- Keep your fuel tank at least half full, so you don’t run out of gas if stranded.
