This week’s heat could be met with thunderstorms across B.C.’s Interior, according to forecasters.
Wednesday is anticipated to be the hottest day of the week in most of B.C., Environment Canada said in a series of tweets earlier that day.
But the national weather agency forecasts that a trough will swing across the province Wednesday evening, generating thunderstorms, risks of hail, heavy downpours and frequent lightning. Troughs are a meteorological term for a bout of low atmospheric pressure that bring wind shifts and clouds.
The storm is anticipated to hit parts of the Okanagan, and be most severe in the Cariboo, until Thursday.
The unstable weather comes as fire risks range from moderate to extreme in those region, according to the BC Wildfire Service.
Open fires are currently banned in the Coastal, Southeast and Cariboo regions.
