Weather in Calgary: Windy Wednesday with chance of rain showers/thunderstorms

0

A low-pressure system near the surface in central Alberta will increase instability across much of the province on Wednesday.

This low pressure system is moving northeastward toward the Northwest Territories, bringing rain and possible convective activity along associated fronts. The heaviest accumulations are expected in the northern and southern halves of Alberta.

Similar to Tuesday, some conditions are lacking for severe thunderstorms to develop. However, strong winds could offset this and increase the risk of severe weather warnings for southern Alberta.

As of 7:30 a.m. Wednesday morning, no weather warnings or advisories had been issued.

Calgary is expected to experience moderate winds throughout Wednesday, initially blowing from the west and southwest at around 20-40 km/h before turning to the northwest at 30-50 km/h near this low.

The counterclockwise rotation around this low pressure system could also pull wildfire smoke back to central Alberta on Wednesday and southern Alberta by Thursday.

On Thursday, the risk of intermittent rain showers and thunderstorms in Calgary will decrease, the sun will shine longer and daytime highs will remain just below seasonal highs.

By Saturday, daily maximum temperatures will rise again to the seasonal 18 to 19 degrees Celsius, with minimum temperatures between 7 and 9 degrees Celsius.
