Prepare for widespread thunderstorm activity across Central and Northern Alberta starting Monday afternoon and persisting into the evening hours. According to the latest data, several of these storms have the potential to become severe, particularly in Central Alberta, including Whitecourt, Edmonton, Red Deer, and Lloydminster.
We have this area in the slight severe risk, with large hail up to the size of golf balls or potentially even larger being the primary threat. Additionally, damaging wind gusts of up to 100 km/h are possible, and there is a slight chance of an isolated tornado.
Surrounding areas, including Calgary, Medicine Hat, and High Prairie, have an isolated severe risk, but it remains uncertain if storms will affect these areas.
Widespread thunderstorm activity is expected across Central and Northern Alberta starting Monday afternoon and lingering into the evening hours. There are indications that some of these storms could reach severe levels, especially around the Red Deer, Edmonton and High Prairie area. The exact severity is unclear so we are sticking with an isolated severe risk although we may upgrade it in a future update.
A localized strong severe risk is anticipated in a zone extending from just west of Red Deer and up into Grande Prairie during the afternoon and evening hours on Sunday.
Isolated pop-up thunderstorms are expected to develop within this region, and given the strong environment, they have the potential to quickly intensify into severe storms. The primary threat associated with these storms will be very large hail, reaching the size of golf balls or even larger. Damaging wind gusts and heavy rainfall are also possible.
While the tornado risk is not particularly strong, there is a possibility of one or two tornadoes with these storms.

Isolated thunderstorms are possible stretching from Southeastern Alberta through the Rockies including Calgary and Grande Prairie. There is a small region in Southeastern Alberta including Brooks, Taber and Medicine Hat that could see some of these storms reach severe levels with large hail and damaging wind gusts. Funnel clouds are also possible with these storms which in rare cases can touch down and become a landspout tornado.
There is an isolated risk for severe thunderstorms on Monday afternoon extending from Lethbridge through Calgary and into Grande Prairie. The primary threats will be large hail up to the size of toonies, 90 km/h wind gusts and funnel clouds. In rare cases, funnel clouds can touch down and become a landspout tornado.
The rest of Southern and Central Alberta including Edmonton can expect localized non-severe thunderstorm activity, but it will be very sporadic and not everyone will see it.
Isolated pop-up thunderstorms are possible along the Rockies on Sunday afternoon and evening. The threat of non-severe storms includes Calgary, Red Deer, Grande Cache and Grande Prairie.
