Thursday’s forecast for Calgary has undergone a few changes over the past few days – originally we had forecast to remain high and dry, then a chance of thunderstorms rolled in on us.
Now it’s downgraded to a chance of light showers tonight as the mid-level marginal instability that governed storm potential earlier in the week has moved north. The first half of the forecast involves plenty of sunshine, which has been the thread of the week.
With the big storm heading east from the Prairies, Calgary set the stage for thunderstorms Friday night as instability emerges in the storm’s wake. The risk of thunderstorms is minimal; the chance of showers is much better.
Special weather reports (in grey) for this storm predict 20 to 40 millimeters of rain and in warning areas 30 to 50 mm are expected.
Parts of British Columbia are also facing weather reports, as snow help is expected at higher elevations there. Something to consider if you have travel plans.
Beyond that, the forecast for Calgary follows a warming cycle. Friday offers a slight drop, but the weekend is more than prepared to catch it. We will fall under a ridge of high pressure on Sunday, with the outlook still looking for midweek showers ahead of the May long weekend.
