The potential thunderstorm activity will begin before 5PM today, here is the “General Thunder Parameter” from UWash for that time. You can see plenty of unsettled activity in the Pacific and some creeping onto the Central parts and West Coast of the Island but notice the image below of Convective Potential actually has very small areas of activity so the activity today should not be too strong.

As the sun rises on Friday morning the unsettled thunderstorm activity will increase quite a bit and spread over the entire South Coast between 8-11AM.  You can see by the 2nd Convective potential image below here that between 11AM and 2PM will be the most intense period of activity with it mainly focused on the Alberni Valley.
