MANITOBA: Thunderstorm Forecast for Tuesday, July 18, 2023
/
FORECAST DISCUSSION
There is a chance of scattered thunderstorms developing along the Saskatchewan border and tracking into Western Manitoba during the afternoon and evening on Tuesday. However, it's important to note that the latest models suggest some lingering rain earlier in the day, which may impact the potential for storm development later in the afternoon. As a result, there is a possibility that the forecasted thunderstorms may not materialize as expected.
If storms do develop, they have the potential to become quite severe, with the main threats including hail ranging from toonie to ping pong ball-sized, wind gusts reaching speeds of up to 100 km/h, and localized flash flooding. Additionally, there is a low possibility of an isolated tornado.
The strongest risk for severe weather is concentrated in the southwestern portion of the province, including areas such as Virden, Souris, Boissevain, and Brandon. However, as the storms progress to the east and north, they are expected to weaken significantly by the time they reach those regions later in the day.
