Alberta: Thunderstorm Forecast for Sunday, June 18, 2023
/
There is the potential for thunderstorm action in Central and Southeastern Alberta. Places like Edmonton, Red Deer, Calgary, Lethbridge, and Medicine Hat could experience isolated pop-up storms during the afternoon and evening on Sunday. Now, most of these storms are expected to stay non-severe. With the exception of an area east of Calgary, as one or two storms may reach severe levels with quarter-sized hail and 90 km/h wind gusts
We're keeping a close watch on conditions that could lead to funnel cloud development. In fact, the environment looks quite strong and may result in several landspout tornadoes. The current data suggest that the target area for these landspouts is quite similar to the region that witnessed landspouts earlier this week. This includes High River, north of Lethbridge, and into Brooks.
As you can see on our map, the highest risk for landspouts falls within the highlighted zone. However, it's important to note that these landspouts could still occur anywhere within both the severe and non-severe risk areas.
