Weather Calgary: Alberta faces 70-90 km/h gusts Thursday afternoon
weather calgary brings a fast change for Alberta this week, with mid- to upper-20s temperatures on Wednesday giving way to cooler, wetter and windier conditions by Thursday and Friday. Widespread rain is expected to develop late Wednesday, and some areas could see snow return by Friday and the weekend.
Thursday afternoon is the sharpest change in the forecast. Wind gusts of 70-90 km/h are possible, while temperatures fall into the mid-teens and embedded thunderstorms remain possible. The wettest period runs from Wednesday night through Friday, with less than 10 mm generally expected in western regions and locally 30+ mm in eastern and northern sections.
Wednesday warmth
Wednesday is expected to stay mild across Alberta before temperatures begin to fall. Mid- to upper-20s readings are forecast for the day, with a chance of thunderstorms along the foothills and in extreme southern Alberta during the afternoon and evening.
Late Wednesday, widespread rain is forecast to develop as a low strengthens. That shift starts the period that is expected to bring the most rain across the province, and it moves the forecast from warm springlike conditions to a cooler, wetter setup heading into Thursday.
Thursday winds and rain
Thursday carries the highest risk for the strongest wind and continuing rain. Gusts of 70-90 km/h are possible in the afternoon, while rain continues and some areas could see embedded thunderstorms. Temperatures are forecast to sit in the mid-teens.
The rain amounts are not expected to be even across the province. Western regions are generally forecast to get less than 10 mm, while eastern and northern sections could receive locally 30+ mm. River levels are running high in northern parts of the province, adding another layer of concern for those areas as the wettest stretch arrives.
Friday and the weekend
By Friday, cooler air is expected to settle in. Single-digit daytime highs are possible for the long weekend, and some areas of Alberta could see snow return on Friday and the weekend.
For readers in the foothills, extreme southern Alberta, and the northern and eastern parts of the province, the main change is the timing: warmth on Wednesday, rain and stronger wind late Wednesday into Thursday, then a colder finish that may turn some places back to snow.
