Weather can feel random, but in Lethbridge the same patterns come back again and again. Once you know them, you can see what’s coming and get ready earlier.
A few local classics
- The chinook cycle: a chinook arch over the mountains, strong west winds, a quick warm-up and melt, then a refreeze when it ends.
- The Arctic push: a sharp wind shift to the north, a big temperature drop over a few hours, and often blowing snow. Days of bitter cold can follow.
- The upslope storm: easterly winds push moist air up against the foothills. These bring our biggest snowfalls, and in spring, heavy wet snow.
- The calm, clear night: light wind and clear sky mean fast cooling, frost and fog in the low spots.
- The summer storm day: a warm, humid morning, cumulus clouds building over the mountains by noon, and thunderstorms rolling east in the afternoon and evening.
What to do
- When you recognize one of these setups starting, get ready for the usual effects. Don’t wait for the warning.
- Keep a simple weather diary for a season. Write down what the sky looked like, the wind direction and what happened next. You’ll be surprised how quickly the patterns show up.
