A developing low pressure system and associated trough will develop in central Alberta tomorrow afternoon bringing thunderstorms to much of the province. Through most of the province thunderstorms have the potential to become severe with large hail and damaging wind gusts being the main threat. Over east-central Alberta there is also the potential to see an isolated tornado. Thunderstorms will initiate in the early afternoon over more western sections and then track eastwards into the late afternoon and evening."
