It was a beautiful spring day in Edmonton, but it's ending on a stormy note.

Severe thunderstorms that developed over the city late Tuesday afternoon and brought wind, rain and lightning have moved off to the east-northeast, with the threat of severe storms ending for the time being.

As of 7 p.m. Tuesday, Environment and Climate Change Canada (ECCC) had ended the severe thunderstorm warning for Edmonton and area and kept the city, St. Albert and Sherwood Park under a thunderstorm watch alert.

ECCC had issued a severe thunderstorm warning at 5:15 p.m. for Edmonton and area as well as regions of the city south along Highway 2 through Red Deer and Calgary.

Earlier severe thunderstorm warnings for areas near Red Deer, Olds, Grande Cache, Botten, Amundson and Alder Flats have also ended.

The Edmonton region will continue to see rain and a few non-severe thundershowers early in the evening. The potential exists for a few more thunderstorms to redevelop mid-evening.

Cloudy, wet, windy and cool conditions will take over on Wednesday with gusts in the 40-50 km/h range through most of the day in Edmonton.

Rain may be in the area for much of the day, but the morning will likely be wetter than the afternoon.  

A severe thunderstorm 'warning' means the severe storms are occurring or imminent, while a 'watch' means potential for severe weather.

High over 20 C, clouds develop in afternoon, thunderstorms

For the second consecutive day, we got into the low 20s in Edmonton.

Sunshine and light wind early in the day gave way to increasing afternoon cloud then thunderstorms.

Edmonton's had back-to-back 20-degree days just a few times this spring:

  • May 9/10
  • May 27/28
  • June 1/2

And there are no three or four-days stretches in the 20s.

That trend will continue as cooler air settles in for Wednesday.

The heaviest, steadiest rain will be in east-central/northeast Alberta.
