Snow forecasts can be confusing if you are only glancing at the percentage chance of snow. Snow removal crews read the same forecasts very differently, looking past the headline number to figure out exactly when and how much equipment needs to be on the road.
The first thing pros check is total accumulation over the storm window, not just the daily total. A forecast calling for 15 centimetres over 18 hours behaves very differently than the same amount falling in 3 hours. Snow ratio matters too. Cold, dry snow piles up fast but is easy to push, while wet, heavy snow near freezing packs down hard and takes longer to clear safely.
Timing is the other piece that separates a rough read from a useful one. Pros watch when the heaviest band of snow is expected to hit, since that tells them when to stage equipment and when overnight or early morning crews need to be ready. Wind is factored in as well, since blowing snow can undo a freshly cleared driveway or lot within an hour even after the snowfall itself has stopped.
Temperature trends before and after the storm shape the plan too. A storm followed by a hard freeze calls for salt or brine applied early to stop bonding, while a storm followed by a warm-up changes when and how much de-icer actually gets used.
Warnings, Watches and Special Weather Statements
Environment Canada uses different alerts for different levels of risk. A special weather statement flags something worth keeping an eye on. A watch means conditions are favourable for a significant event. A warning means the event is happening or is very likely. When you see a warning for the London area, it is a good time to make sure your car is in the garage or off the driveway and anything that could be buried, such as hoses or decorations, is out of the way.
What the Forecast Means for Your Driveway
For homeowners, the number that matters most is whether the snowfall will reach the trigger depth. Thames Valley Snow seasonal plans run on a 5 cm trigger, so once that much snow has fallen your property is added to the route automatically. A forecast of 2 cm of light flurries usually means no visit, while a forecast of 10 to 15 cm almost certainly means one, and a long storm may mean more than one.
Freezing rain and ice pellets deserve extra attention. They often add little depth but create the most dangerous surfaces of the winter. If your plan includes seasonal salting ($175 for the season), that service covers freezing rain and refreeze conditions, which is exactly when a slippery walkway becomes a real hazard.
Simple Habits That Help on Storm Days
Check the forecast the night before, move vehicles if you can, and keep the edges of the driveway clear of anything a plow could catch. Edge markers placed before the season help the operator find the pavement when everything is white. After each visit you can check the timestamped photo to see when the work was done.
Frequently Asked Questions
Do I need to call when a big storm is forecast?
No. On a seasonal plan, service starts automatically once 5 cm has fallen.
Why is wet snow harder to clear?
Wet snow near the freezing mark is heavy and packs down quickly, so it takes more effort to move and is more likely to leave a slippery base if it is not cleared promptly.
