Environment Canada issued a thunderstorm watch for the Weyburn area late Thursday afternoon. This joined a number of other watches that had been in effect since around noon, along with warnings that had popped up in parts of south-central Saskatchewan.
Thunderstorms have developed through the afternoon as an upper-level disturbance has been moving through southern portions of the province. Some of the thunderstorms that have developed are likely to be severe.
A thunderstorm watch is issued when the conditions are favourable for developing severe thunderstorms. These storms, when they develop, are capable of producing strong wind gusts, large hail and heavy rain. Severe thunderstorms can also produce tornadoes, and heavy downpours can cause flash flooding and water pooling on roads.
