“They said it would snow and it didn’t.” Maybe. Or maybe it came six hours later than expected.
Forecasts usually get the pattern right: a cold front is coming, a chinook is building, a storm is moving in. What’s harder to pin down is exactly when it arrives, how strong it is, and exactly where the heaviest part lands. Southern Alberta makes this extra tricky, because the mountains can speed systems up, slow them down or split them.
When a forecast seems wrong, ask:
- Was it the timing? The front arrived, just later than expected.
- Was it the intensity? It snowed, but less than forecast.
- Was it the location? The heavy snow fell 50 km north of the city.
Thinking this way makes forecasts much more useful. A “wrong” forecast that was only three hours late still told you what was coming.
What to do
- Look at the forecast trend, not just one forecast. If several updates in a row keep pushing the timing later, plan for later.
- Watch local conditions as the event gets close. Wind shifts, pressure changes and the temperature trend often tell you the system is arriving.
- Treat the first few hours of a forecast window as a “maybe” and the middle as the most likely.
