There's a risk of afternoon thunderstorms for much of the province Wednesday afternoon, with the greatest risk of severe weather focused on west-central regions. Smoke is generally clearing through the rest of the week, but a west and southwest flow on Wednesday and Thursday will continue to bring pockets of haze into southern Alberta.
