Westlock residents can expect a mixed bag of weather this week, starting with a chance of thunderstorms on Monday before a warming trend brings sunny skies and temperatures climbing well above normal by Thursday. According to Environment Canada, no weather alerts are currently in effect for the area.
As of 10 a.m. Monday, conditions in Westlock were cool and damp at 12.2 C with humidity at 89 percent and light northwest winds. The forecast for the rest of the day calls for a mix of sun and cloud, a 60 percent chance of showers, and a risk of a thunderstorm late this afternoon, with a high of 17 C and a UV index of 6, or high.
Things start to turn around on Tuesday. Sunny skies are expected after any morning fog patches clear, and the daytime high will reach 22 C. The warming continues Wednesday with more sunshine and a high of 24 C, setting the stage for Thursday to be the warmest day of the week at 25 C. That is roughly 3 degrees above the normal June high of 22 C for Westlock.
The pleasant stretch will be short-lived, however. Environment Canada says unsettled weather returns Friday, with increasing cloudiness and a high of 24 C before showers move in Friday night. Saturday looks wet with showers and a high of only 16 C, and Sunday brings a 70 percent chance of more showers and a high of 18 C.
June is typically the third busiest month for thunderstorms in Alberta, and the province averages about 15 tornadoes a year. The Westlock area, an agricultural hub about 85 kilometres north of Edmonton, relies heavily on June rainfall to get crops started. A wet end to the week could help ease moisture concerns that have been flagged for the 2026 growing season.
