Lethbridge residents can expect a shift back to wet weather starting Friday, June 26, 2026, after enjoying a stretch of sunny and warm days mid-week. The Weather Network forecasts a 70 per cent chance of showers and a risk of thunderstorms for Friday afternoon and evening, with 1 to 3 millimetres of rain possible. Temperatures will reach a high of 26°C before dropping to 19°C in the evening, with an overnight low near 12°C.
The unsettled pattern is set to linger through the weekend. Saturday will see a mix of sun and clouds during the day, with showers developing in the evening and a growing chance of rain overnight, when the probability jumps to 90 per cent. Sunday morning looks to be the wettest period, with a 90 per cent chance of rain and 5 to 10 millimetres expected. Showers could continue into Sunday afternoon and Monday, though lighter amounts are likely.
This comes after several days of mainly sunny skies on Tuesday and Wednesday, with a mix of sun and clouds on Thursday and highs between 22°C and 26°C. The return of rain aligns with June being Lethbridge’s wettest month on average, though totals can vary widely because of local thunderstorm activity.
Environment Canada’s summer outlook for June through August gives the Lethbridge area a 20 to 40 per cent chance of near-normal temperatures. Meteorologist Alysa Pederson noted that summer thunderstorms can bring sudden downpours to specific spots, making rainfall predictions tricky.
No weather warnings are in effect for Lethbridge, but residents with outdoor plans this weekend are encouraged to monitor the forecast closely and be ready for sudden changes.
