Residents in Lethbridge, Alberta, should prepare for a sharp return to winter conditions this week as temperatures are expected to drop significantly following a period of mild weather. According to Environment Canada, a high of 11°C on Monday, March 23, 2026, will give way to much colder air and a 60 per cent chance of rain showers or flurries by Wednesday night.
The shift began early Monday morning at the Lethbridge Airport, where temperatures were recorded at -2.2°C with a wind chill making it feel like -8. While Tuesday will see a high of 8°C, the temperature is expected to plunge to a low of -10°C on Wednesday night. The Weather Network also noted these sharp contrasts, reporting that the spring-like warmth seen earlier this month is being replaced by conditions that feel much colder.
Moisture is expected to move into the region starting Tuesday with a 30 per cent chance of rain showers or flurries, increasing to a 60 per cent chance by Wednesday evening. Alberta Transportation and Economic Corridors warns that these fluctuating temperatures can make roads dangerous, especially on bridge decks which often become slicker than other surfaces. Drivers are legally required to adjust their speed for the conditions to avoid fines and ensure safety on the highway.
This type of unpredictable weather is common in southern Alberta due to Chinook winds, which can cause temperatures to swing by 20 degrees in just a few hours. Historical data from Current Results shows that Lethbridge typically receives about 22.5 centimetres of snow during the month of March. By Thursday, March 26, 2026, the daytime high is only expected to reach 2°C, reminding residents to keep their winter gear handy for a few more days.
